Zin SRM, Kassim NM, Alshawsh MA, Hashim NE, Mohamed Z

Biomed Pharmacother, 2017 Jul;91:611-620.
PMID: 28486192 DOI: 10.1016/j.biopha.2017.05.011

Anastatica hierochuntica L. (A. hierochuntica) is a desert plant consumed by people across the globe to treat various medical conditions. This review is aimed at providing a summary of the scientific findings on biological activities of A. hierochuntica and suggests areas in which further research is needed. This systematic review was synthesized from the literature obtained from the following databases; PubMed, Science Direct, Web of Science, Ovid Medline, Scopus, Google Scholar and WorldCat. Previous studies have indicated that the methanolic and aqueous extracts of this plant have antioxidant, antifungal and antimicrobial activities. It was shown to have the ability to activate phagocytes and to possess microbicidal activity, thereby causing increased resistance to infection. Both methanolic and aqueous extracts of this plant were also demonstrated to have a hypoglycaemic property, whilst the methanolic extract significantly exhibited hypolipidaemic effects in diabetic rats. Moreover, the methanolic extract of A. hierochuntica has been suggested to have hepatoprotective properties. This is supported by its ability to significantly decrease transaminase and alkaline phosphatase activities in alloxan-induced diabetic rats. Besides, this desert plant exhibited anti-inflammatory, anti-melanogenic and gastroprotective activities. Even though A. hierochuntica is widely used, studies on this plant are still scarce, thus its reputed biological activities and medical benefits require critical evaluation. Before A. hierochuntica can be used clinically, further studies need to be conducted to increase our understanding of the effects of this plant, its constituents, and possible mechanisms of action.

Ficus deltoidea or Mas cotek is one of the common medicinal plants used in Malaysia has been claimed to have antidiabetic activity. However, scientific evidence to confirm its efficacy is still lacking. Thus, the present study was undertaken to evaluate the potential of ethanolic extract of Ficus deltoidea to reduce hyperglycaemia in streptozotocininduced diabetic rats at different prandial state. The results showed that, ethanolic extract of Ficus deltoidea significantly reduced fasting and postprandial hyperglycemia particularly after 4 and 6 hours of extract administration. Likewise, glucose tolerance activity was significantly improved in the presence of Ficus deltoidea ethanolic extract at a low dose, 100 mg/kg. It is suggested that ethanolic extract of Ficus deltoidea at particular doses, possess fasting and postprandial antihyperglycemic activity as well as glucose tolerance activity in streptozotocin-induced diabetic rats.

PMID: 28603121

Inhibition of intestinal α-amylase and α-glucosidase is an important strategy to regulate diabetes mellitus (DM). Antioxidants from plants are widely regarded in the prevention of diabetes. Fruits of Elettaria cardamomum (L.) Maton (Zingiberaceae) and Piper cubeba L. f. (Piperaceae) and flowers of Plumeria rubra L. (Apocynaceae) are traditionally used to cure DM in different countries. However, the role of these plants has been grossly under reported and is yet to receive proper scientific evaluation with respect to understand their traditional role in the management of diabetes especially as digestive enzymes inhibitors. Hence, methanol and aqueous extracts of the aforementioned plants were evaluated for their in vitro α-glucosidase and α-amylase inhibition at 1 mg/mL and quantification of their antioxidant properties (DPPH, FRAP tests, total phenolic and total flavonoids contents). In vitro optimization studies for the extracts were also performed to enhance in vitro biological activities. The % inhibition of α-glucosidase by the aqueous extracts of the fruits of E. cardamomum, P. cubeba and flowers of P. rubra were 10.41 (0.03), 95.19 (0.01), and -2.92 (0.03), while the methanol extracts exhibited % inhibition 13.73 (0.02), 92.77 (0.01), and -0.98 (0.01), respectively. The % inhibition of α-amylase by the aqueous extracts were 82.99 (0.01), 64.35 (0.01), and 20.28 (0.02), while the methanol extracts displayed % inhibition 39.93 (0.01), 31.06 (0.02), and 39.40 (0.01), respectively. Aqueous extracts displayed good in vitro antidiabetic and antioxidant activities. Moreover, in vitro optimization experiments helped to increase the α-glucosidase inhibitory activity of E. cardamomum. Our findings further justify the traditional claims of these plants as folk medicines to manage diabetes, however, through digestive enzymes inhibition effect.

Fulltext Olanzapine-induced Cataract in a Teenage Girl

Lim CZ, Sonny Teo KS, Tai E

Cureus, 2018 Apr 30;10(4):e2553.
PMID: 29974009 DOI: 10.7759/cureus.2553

Cataract, defined as cloudiness of the lens, is a common adverse effect of first-generation antipsychotic medications. Newer generation antipsychotics, also known as atypical antipsychotics, are less commonly associated with cataract. A 19-year-old girl with underlying schizophrenia on olanzapine for the past two years complained of gradual blurring of vision in both eyes for four months prior to presentation. On examination, the best corrected visual acuity was counting finger in both eyes. The anterior segment examination showed bilateral diffuse cortical cataract precluding fundus examination. Systemic examination was unremarkable. Blood investigations revealed a high random blood sugar, which normalised after she was initiated on oral hypoglycemic medication. After bilateral lens aspiration, her visual acuity was 6/6 bilaterally. Olanzapine may be cataractogenic via its action as a serotonin antagonist, which results in reduced glucose responsiveness of the pancreatic beta-cells. Patients on anti-psychotic medication are at risk of developing diabetes mellitus and cataract compared to the general population. Screening for diabetes mellitus should be part of the follow-up of these patients. Ophthalmological evaluation is warranted in the presence of visual complaints.

Butt M, Ali AM, Bakry MM

Curr Diabetes Rev, 2019;15(5):402-406.
PMID: 30156163 DOI: 10.2174/1573399814666180828152754

BACKGROUND: This study evaluated the association between self-reported adherence with concurrent and subsequent glycemic control amongst type 2 diabetes patients at a tertiary care hospital in Malaysia.
METHODS: Demographic and clinical variables were assessed at baseline, after three and six months in 73 type 2 diabetes patients. Regression analysis, using SPSS, evaluated the concurrent and longitudinal association of medication adherence and glycemic control. Potential confounders of variables were identified using bi-variate correlation analyses.
RESULTS: Concurrent Medication adherence and HbA1c association were significant after adjusting for ethnicity (P = 0.005). For longitudinal observation at 3 months, the association was significant after adjusting for ethnicity (P = 0.016); however, it became non-significant when baseline glycemic control was included in the model (P = 0.28).
CONCLUSION: Easy to administer MALMAS significantly predicted concurrent glycemic control independent of potential confounders. This association persisted in longitudinal observation after 3 months when adjusted for confounders and became non-significant after adjusting for baseline glycemic control.

Abbasi MA, Hassan M, Ur-Rehman A, Siddiqui SZ, Hussain G, Shah SAA, et al.

Comput Biol Chem, 2018 Dec;77:72-86.
PMID: 30245349 DOI: 10.1016/j.compbiolchem.2018.09.007

The heterocyclic compounds have been extensively reported for their bioactivity potential. The current research work reports the synthesis of some new multi-functional derivatives of 2-furoic piperazide (1; 1-(2-furoyl)piperazine). The synthesis was initiated by reacting the starting compound 1 with 3,5-dichloro-2-hydroxybenzenesulfonyl chloride (2) in a basic, polar and protic medium to obtain the parent sulfonamide 3 which was then treated with different electrophiles, 4a-g, in a polar and aprotic medium to acquire the designed molecules, 5a-g. These convergent derivatives were evaluated for their inhibitory potential against α-glucosidase, acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes. Acarbose was used as a reference standard for α-glucosidase inhibition while eserine for AChE and BChE inhibition. Some of the synthesized compounds were identified as promising inhibitors of these three enzymes and their bioactivity potentials were also supported by molecular docking study. The most active compounds among the synthetic analogues might be helpful in drug discovery and development for the treatment of type 2 diabetes and Alzhiemer's diseases.

PMID: 31787894 DOI: 10.3389/fphar.2019.01306

Objective: Medication adherence is defined as taking medications as advised and prescribed by health care professionals for stated duration. Diabetes mellitus (DM) is one of the most common chronic illnesses in Saudi Arabia. This study aimed to document medication adherence in Saudi patients with type 2 diabetes. Methods: A quantitative cross-sectional study was conducted in Saudi out-patients with type 2 DM in the city of Khobar, Saudi Arabia. The study used the General Medication Adherence Scale (GMAS) to document medication adherence in this population. Data was analyzed through SPSS version 23. Study was ethically approved. Results: Data was collected from 212 patients. Few patients (35.8%) had high adherence to anti diabetic medications. The correlation between HbA1c level and adherence score was negative and significantly strong (ρ = -0.413, p < 0.0001). Most patients (N = 126, 59.4%) modified their medication therapy during month of Ramadan and on Eid occassion. Education level was not a determinant of adherence in this population. Conclusion: This study highlighted that medication adherence is influenced by religious and social factors. Patient counseling is required to improve patient beliefs and increase awareness of adhering to prescribed anti diabetic pharmacotherapy. A pharmacist can play constructive role of a disease educator and patient counselor.

PMID: 31081759

Echinops echinatus is traditionally an important plant that finds its extensive use as a diuretic, anti-inflammatory, anti-pyretic, nerve tonic, abortifacient, aphrodisiac, antiasthmatic, and antidiabetic agent. The current study investigates protection against the hyperglycemia and dyslipidemia in alloxan-induced (type I diabetes) and fructose-fed insulin resistance (type II diabetes) models of diabetes treated with aqueous methanolic root extract of E. echinatus (Ee.Cr). Albino rats were treated orally with Ee.Cr at doses 100, 300 and 500mg/kg. The fasting blood glucose was measured by glucometer, while standard kits were used to determine the levels of serum total cholesterol, triglycerides and HDL. The administration of Ee.Cr significantly (P<0.001) reduced the FBG concentration in a dose-dependent pattern in alloxan-induced and fructose-fed diabetic rats. The Ee.Cr also corrected the dyslipidemia associated with fructose and alloxan-induced diabetes by significantly (P<0.001) decreasing the concentration of serum total cholesterol, triglycerides, and LDL and by increasing HDL concentration. Ee.Cr also significantly (P<0.001) improved the glucose tolerance in fructose-fed rats. We conclude that Ee.Cr has antidiabetic and antidyslipidemic effects in both insulin-dependent alloxan-induced diabetes and fructose-induced insulin resistance diabetes rat models.

Antihyperglycemic activity of F. deltoidea ethanolic extract in normal rats

Zainah Adam, Shafii Khamis, Muhajir Hamid, Muhammad Hanaffi Mohd. Mokhtar, Amin Ismail

Sains Malaysiana, 2011;40.

Ficus deltoidea is one of the common medicinal plants used in Malaysia. This epiphytic plant, from the Moraceae family has been claimed to have antidiabetic property. However, scientific evidence to confirm its efficacy is still lacking. The present study was undertaken to evaluate the effect of ethanolic extract of F. deltoidea on glucose level in normal rats at different prandial state. The results showed that, all doses of ethanolic extract of F. deltoidea reduced fasting blood glucose particularly after 6 h of administration. Interestingly, the extract did not produce severe hypoglycemia as shown by its comparable effect with metformin. Likewise, postprandial hyperglycemia was also significantly reduced particularly after 4 and 6 h of administration. Furthermore, extract was used at a dose of 1000 mg/kg b.w., reduced postprandial hyperglycemia similar to metformin. This suggests that postprandial antihyperglycemic mechanism of this extract is mediated through enhancement of glucose uptake into muscle cells and reduction of hepatic gluconeogenesis. Glucose tolerance activity was also significantly improved in the presence of ethanolic extract of F. deltoidea. From this study, it is suggested that ethanolic extract of F. deltoidea reduced postprandial hyperglycemia and improves glucose tolerance activity in normal rats.

Antioxidant, α-amylase and α-glucosidase activity of various solvent fractions of I. obliquus and the preventive role of active fraction against H2 O2 induced damage in hepatic L02 cells as fungisome

Gao X, Santhanam RK, Xue Z, Jia Y, Wang Y, Lu Y, et al.

J Food Sci, 2020 Apr;85(4):1060-1069.
PMID: 32147838 DOI: 10.1111/1750-3841.15084

Inonotus obliquus is a traditional mushroom well known for its therapeutic value. In this study, various solvent fractions of I. obliquus were preliminarily screened for their antioxidant, α-amylase and α-glucosidase inhibition properties. To improve the drug delivery, the active fraction (ethyl acetate fraction) of I. obliquus was synthesized into fungisome (ethyl acetate phophotidyl choline complex, EAPC) and its physical parameters were assessed using Fourier transform infrared spectroscopy (FTIR), High performance liquid chromatography (HPLC), Scanning electron microscope (SEM), and ς potential analysis. Then normal human hepatic L02 cells was used to evaluate the cytotoxicity of EAPC. The results showed that EA fraction possesses significant free radical scavenging, α-amylase and α-glucosidase inhibition properties. FTIR, SEM, and HPLC analysis confirmed the fungisome formation. The particle size of EAPC was 102.80 ± 0.42 nm and the ς potential was -54.30 ± 0.61 mV. The percentage of drug entrapment efficiency was 97.13% and the drug release rates of EAPC in simulated gastric fluid and simulated intestinal fluid were 75.04 ± 0.29% and 93.03 ± 0.36%, respectively. EAPC was nontoxic to L02 cells, however it could selectively fight against the H2 O2 induced oxidative damage in L02 cells. This is the first study to provide scientific information to utilize the active fraction of I. obliquus as fungisome. PRACTICAL APPLICATIONS: Inonotus obliquus (IO) is a traditional medicinal fungus. The extracts of IO have obvious antioxidant and hypoglycemic activities. Ethyl acetate (EA) fraction of IO was encapsulated in liposomes to form EAPC. EAPC has a sustained-release effect. It has nontoxic to L02 cells and could protect L02 cells from oxidative damage caused by hydrogen peroxide. This study could provide new ideas for the treatment of diabetes.

In this research, a milk thistle seed extract (MTSE)-rich medium was used as a capping and reducing agent for the one-pot biosynthesis of ZnO/Ag (5 wt%) nanostructure. The sample was systematically characterized through various techniques and its strong biomolecule‒metal interface structure was supported by the results. The efficacy of the derived nanostructure (MTSE/ZnO/Ag) was evaluated in vivo on the basis of its therapeutic effects on the main complications of Type 1 diabetes (hyperglycemia, hyperlipidemia, and insulin deficiency). For this purpose, the changes in the plasma values of fasting blood glucose, total cholesterol, total triglyceride, high-density lipoprotein cholesterol, and insulin in alloxan-diabetic Wistar male rats were compared with those in healthy and untreated diabetic controls after a treatment period of 16 days. The antidiabetic results of MTSE/ZnO/Ag were compared with those obtained from pristine ZnO, MTSE, and insulin therapies. The health conditions of the rats with Type 1 diabetes were significantly enhanced after treatment with MTSE/ZnO/Ag (p

PMID: 30822495 DOI: 10.1016/j.diabres.2019.02.021

AIMS: To describe the characteristics and fasting experience of a subgroup of patients in the VISION study who initiated insulin therapy and chose to fast during Ramadan, and to discuss the VISION Ramadan substudy data in the context of previous Ramadan studies.
METHODS: The VISION study was a prospective, non-interventional, observational study of adult patients with Type 2 diabetes mellitus in 6 countries in the Western Pacific, Middle East and North Africa, receiving insulin injection therapy for the first time. In this VISION Ramadan substudy, fasting data was collected during Ramadan 2014 and 2015.
RESULTS: Of 1617 patients in the VISION study, data was collected for 357 patients who chose to fast during Ramadan. At baseline, mean HbA1c was 10.1%, duration of diabetes was 8.8 years, and mean BMI was 30 kg/m2. All patients with non-missing data (n = 169) received advice on fasting during Ramadan. The majority of patients fasted for the full month of Ramadan, and around one-third of patients fasted outside Ramadan.
CONCLUSIONS: Here we provide an update on the characteristics and Ramadan experience of patients with Type 2 diabetes mellitus who initiated insulin therapy and chose to fast during Ramadan. There is still a need to explore patient's experience during fasting, and identify and address methods to better help manage those patients.

Int J Environ Res Public Health, 2020 03 09;17(5).
PMID: 32182755 DOI: 10.3390/ijerph17051765

The implementation of Family Doctor Concept (FDC) to restructure the primary healthcare systems in Malaysia were expected to enhance patient's satisfaction on doctor-patient interaction and subsequently improved glycaemic control among Type 2 Diabetes Mellitus (T2DM) patients. Thus, this study aims to determine the difference in doctor-patient interaction satisfaction between T2DM patients attended FDC-implemented clinic vs non-FDC clinics, and to determine the association between FDC-implemented clinic and doctor-patient interaction satisfaction towards glycaemic control. A cross-sectional study was conducted throughout 10 districts in Kelantan from February until May 2019 using interview-guided Skala Kepuasan Interaksi Perubatan-11 (SKIP-11) and proforma checklist. Data were analyzed using SPSS ver.24. Chi-square statistic used to determine the difference in doctor-patient interaction satisfaction between both clinics type. Multiple logistic regression used to examine the association between FDC-implemented clinic and doctor-patient interaction satisfaction towards glycaemic control. Twenty primary health clinics involved, and 772 T2DM patients recruited. FDC clinics attendees has higher proportion of satisfaction (40.1%) compared to non-FDC attendees (33.7%) (p = 0.070). Multiple logistic regression confirmed the association of FDC-implemented health clinics (Adj. OR 1.63, p = 0.021), and doctor-patients interaction satisfaction (Adj. OR 1.77, p = 0.005) towards glycaemic control. Hence, strengthening of FDC in primary healthcare and improve the doctor-patient interaction satisfaction were essential to escalate good glycaemic control.

Gynura procumbens leaf improves blood glucose level, restores fertility and libido of diabetic-induced male rats

Khaidatul Akmar Kamaruzaman, Mahanem Mat Noor

Sains Malaysiana, 2017;46:1471-1477.

Gynura procumbens (GP) has been widely used in traditional medicine due to its ability in treating various types
of diseases. This study was carried out to determine the effects of GP on blood glucose level, fertility and libido of
streptozotocin-induced male rats. A total of 42 male rats were randomly sorted into six groups; normal, negative and
positive controls and three treated groups with different dosages of GP aqueous extract (GPAE); 150, 300 and 450 mg/kg.
Each group was treated via oral feeding for 14 consecutive days. The rats were sacrificed on day 15 for further analysis.
Administration of GPAE significantly lowered the fasting blood glucose (FBG) level and increased the plasma testosterone
level of diabetic-induced rats compared to the positive and negative control groups. There was also a significant increase
in the sperm quality as well as the fertility of GPAE treated groups compared to the negative and positive control groups.
Sexual behaviour analysis demonstrated that GPAE is able to facilitate the expression of sexual behaviour significantly;
increased mounting frequency and reduced mounting latency. These lines of evidence suggested that GPAE can act as
antihyperglycaemic, profertility and libido agents. However, its mechanism(s) remains unresolved.

Oral calcium pectinate-insulin nanoparticles: influences of alginate, sodium chloride and Tween 80 on their blood glucose lowering performance

Wong TW, Sumiran N

J Pharm Pharmacol, 2014 May;66(5):646-57.
PMID: 24329400 DOI: 10.1111/jphp.12192

Objective: Examine the formation of pectin-insulin nanoparticles and their blood glucose lowering properties.

Methods: The calcium pectinate nanoparticles were prepared by ionotropic gelation method, with alginate, sodium chloride or Tween 80 as additive. Their in vitro physicochemical, drug release and in vivo blood glucose lowering characteristics were evaluated.

Key findings: Spherical calcium pectinate-insulin nanoparticles were characterized by size, zeta potential, insulin content and insulin association efficiency of 348.4 ± 12.9 nm, -17.9 ± 0.8 mV, 8.4 ± 1.0% and 63.8 ± 7.4%, respectively. They released less than 25% insulin following 24 h in simulated intestinal medium and exhibited delayed blood glucose lowering effect in rats. Incorporation of solubilizer sodium chloride or Tween 80 into nanoparticles did not enhance blood glucose lowering capacity owing to sodium chloride reduced matrix insulin content and Tween 80 interacted with water and had its blood glucose dilution effect negated. Combination of nanoparticles with alginate gel to allow prolonged intestinal residence and more insulin release did not enhance their blood glucose lowering capacity because of calcium alginate-cross-linked gel formation that could retard insulin release and migration into systemic circulation.

Conclusion: Physicochemical responses of additives in vivo affected blood glucose regulation property of pectin-insulin nanoparticles.

Keywords: Tween 80; alginate; insulin; nanoparticle; pectin.

We have synthesized new hybrid class of indole bearing sulfonamide scaffolds (1-17) as α-glucosidase inhibitors. All scaffolds were found to be active except scaffold 17 and exhibited IC50 values ranging from 1.60 to 51.20 µM in comparison with standard acarbose (IC50 = 42.45 µM). Among the synthesized hybrid class scaffolds 16 was the most potent analogue with IC50 value 1.60 μM, showing many folds better potency as compared to standard acarbose. Whereas, synthesized scaffolds 1-15 showed good α-glucosidase inhibitory potential. Based on α-glucosidase inhibitory effect, Scaffold 16 was chosen due to highest activity in vitro for further evaluation of antidiabetic activity in Streptozotocin induced diabetic rats. The Scaffold 16 exhibited significant antidiabetic activity. All analogues were characterized through 1H, 13CNMR and HR MS. Structure-activity relationship of synthesized analogues was established and confirmed through molecular docking study.
