Sakeena MH, Elrashid SM, Muthanna FA, Ghassan ZA, Kanakal MM, Laila L, et al.

PMID: 20513974

This study sets out to investigate the in vitro permeation of ketoprofen from the formulated nanoemulsions through excised rat skin. In vitro permeation of ketoprofen nanoemulsion through rat skin was evaluated in Franz diffusion cells and compared with marketed product (Fastum gel). Limonene which has been reported to be a good enhancer for ketoprofen was selected. Moreover the effects of limonene which was added to the nanoemulsion formulations at levels of 1%, 2%, 3% and on rat skin permeation of ketoprofen were also evaluated. The selected optimized formulation was further studied for skin irritation. Utilization of limonene as a penetration enhancer increased the permeation of ketoprofen from the formulated nanoemulsion with increasing concentrations of limonene. The results obtained showed that nanoemulsion with 3% limonene produced similar and comparable skin permeation of ketoprofen with marketed formulation and the skin irritation study on rats showed the optimized formulation prepared was safe.
Formulation and in vitro evaluation of ketoprofen in palm oil esters nanoemulsion for topical delivery

Sakeena MH, Muthanna FA, Ghassan ZA, Kanakal MM, Elrashid SM, Munavvar AS, et al.

J Oleo Sci, 2010;59(4):223-8.
PMID: 20299769

The aim of the present study is to formulate and investigate the potential of nanoemulsion formulation for topical delivery of ketoprofen. In this study, Palm Oil Esters (POEs) a newly introduced oil by Universiti Putra Malaysia researchers was chosen for the oil phase of the nanoemulsion, because the oil was reported to be a good vehicle for pharmaceutical use. Oil-in-water nanoemulsion was prepared by spontaneous emulsification method. The droplets size was studied by laser scattering spectroscopy (Nanophox) and Transmission Electron Microscopy (TEM). Franz diffusion cells were used, to determine the drug release and drug transferred through methyl acetate cellulose membrane (artificial membrane). The results of droplets size analysis shows the droplets are in the range of nanoemulsion which is below than 500 nm. The in vitro release profile shows a sufficient percentage of drugs released through the methyl acetate cellulose membrane. This initial study showed that the nanoemulsion formulated using POEs has great potential for topical delivery of ketoprofen.

Plums is one of the most cultivated stone fruits due to its fast growing popularity. It has various traditionally recognized health benefits. There are two main commercial types of plums: the European plum (Prunus domestica) and the Japanese plum (Prunus salicina), each having many varieties. Researchers are gathering further evidence of pharmacological effects for plums by scientifically studying its anti-inflammatory, antioxidant properties. A systematic review analysing the literature related to the effects of plums on prevention and treatment of cancer is warranted. This is the first review examining the cancer-related effects of plums. Antioxidation properties of the active constituents of plum were also compared. Scopus, Google Scholar, PubMed, Medxriv and Cochrane Library databases, from their date of inception until July 2021 were utilized. The risk of bias was assessed using CONSORT checklist. A total of 6639 studies were screened and eventually only 54 studies were included. Full-text review of included studies revealed that plum extracts were rich in antioxidants. Overall, most of the studies that fulfilled the eligibility criteria were in vitro and a few clinical studies involving in vivo work. Therefore, it would be beneficial to perform more studies on animals or humans, to confirm that the result obtained from these in vitro studies are able to be extrapolated in a wider range of applications. Further clinical and in vivo studies are warranted to validate plums as a functional food for treatment and prevention of cancer.
Gas Chromatography-Mass Spectrometry (GC-MS) Analysis of Scaphium Affine Seed Extract and Assessment of Its Anti-hemorrhoidal Efficacy

Abbas SA, Khan A, Fatima M, Kalusalingam A, Kanakal MM, Inamdar SK, et al.

Antiinflamm Antiallergy Agents Med Chem, 2024;23(2):118-128.
PMID: 38357954 DOI: 10.2174/0118715230285370240131111539

BACKGROUND: Seeds of plant Scaphium affine are traditionally used by the healers of "India" for the treatment of piles.
OBJECTIVES: The primary objective of the study was to assess the anti-hemorrhoidal potential of the ethanolic seed extract of Scaphium affine.
METHODS: After the soxhlet extraction method, the seed extract from Scaphium affine was first submitted to phytochemical standardization and then GC-MS analysis. Rats were given Croton oil and Jatropha oil to develop hemorrhoids, and Scaphium affine seed extract (ESA) was administered orally for 5 days and 3 days, respectively, at doses of 1000 and 500 mg/kg. The Rectoanal coefficient (RAC) was calculated as an inflammatory marker. The hemorrhoidal tissues were also subjected to cytokine profiling, biochemical estimation and histopathology.
RESULTS: ESA demonstrated the presence of flavonoids, saponins, phytosterols, phenols, and tannins. GCMS analysis elucidated the presence of hexadecanoic acid 2 hydroxy -1,3 propane diyl ester,9 Octadecanoic acid ethyl ester, Cyclohexane 1,4 di methyl cis, Farnesol isomer,1, E-11, Z-13 octa decatriene, Stigmasterol, N-(5 ethyl -1,3,4-thiadiazol-yl) benzamide, N, N Dinitro 1,3,5,7 tetraza bicyclo 93,3,1) as major phytoconstituents. The results depicted more potent anti-hemorrhoidal activity of ESA at 1000 mg/kg, p.o., which was evident through a decrease in RAC. A significant decline in the levels of IL-1β, IL-6, and TNF-α expression was observed, along with the restoration of altered antioxidants and enzymes. Histopathological analysis confirmed the tissue recovery as it revealed minimal inflammation and decreased dilated blood vessels in treated animals.
CONCLUSION: Based on the results it can be concluded that seeds of Scaphium affine showed significant anti-hemorrhoid agents which may be attributed to their anti-inflammatory and anti-oxidant potential due to the presence of certain phytoconstituents in it. The study also supports the traditional use of seeds of Scaphium affine for the first time in the treatment of hemorrhoids.

PMID: 39082166 DOI: 10.2174/0118715230309053240718122527

INTRODUCTION: This research aims to create a gel formulation of Brassica juncea leaf extract and assess its anti-inflammatory properties using an in silico study. The anti-inflammatory activity has been compared with Diclofenac molecules in PDB id: 4Z69. Further, the Absorption, Distribution, Metabolism, Excretion, and Toxicity analysis has been performed to ensure the therapeutic potential and safety of the drug development process. The Quality by Design tool has been applied to optimize formulation development.
METHODS: The extracted gel is characterized by performing Fourier transformer infrared, zeta potential, particle size, Scanning Electron Microscope, and entrapment efficiency. Further, the formulation is evaluated by examining its viscosity, spreadability, and pH measurement. An In vitro study of all nine extract suspensions was conducted to determine the drug contents at 276 nm.
RESULTS: The optimized suspension has shown the maximum percentage of drug release (82%) in 10 hours of study. Animal study for anti-inflammatory activity was performed, and results of all five groups of animals compared the % inhibition of paw edema at three hours; gel (56.70%), standard (47.86%), and (39.72%) were found.
CONCLUSION: The research could conclude that the anti-inflammatory activity of gel formulation is high compared to extract, and a molecular docking study validates the anti-inflammatory therapeutic effects. ADMET analysis ensures the therapeutic effects and their safety.
