METHODS: We analyzed data (2012-18) from the prospective cohort Dialysis Outcomes and Practice Patterns Study for 1544 GCC patients ≥18 years old and on dialysis >180 days.
RESULTS: Thirty-four percent of GCC HD patients had low Kt/V (<1.2) versus 5%-17% in Canada, Europe, Japan and the USA. Across the GCC countries, low Kt/V prevalence ranged from 10% to 54%. In multivariable logistic regression, low Kt/V was more common (P
BACKGROUND: The Arabian Gulf population is at high risk for atherosclerotic cardiovascular disease at younger ages. There is no up-to-date study regarding dyslipidemia management in this region, especially given the recent guideline-recommended LDL-C targets.
OBJECTIVE: Up-to-date comprehensive assessment of the current dyslipidemia management in the Arabian Gulf region, particularly in view of the recent evidence of the additive beneficial effects of ezetimibe and proprotein convertase subtilisin/kexin-9 (PCSK-9) inhibitors on LDL-C levels and cardiovascular outcomes.
METHODS: The Gulf Achievement of Cholesterol Targets in Out-Patients (GULF ACTION) is an ongoing national observational longitudinal registry of 3000 patients. In this study, adults ≥18 years on lipidlowering drugs for over three months from out-patients of five Gulf countries were enrolled between January 2020 and May 2022 with planned six-month and one-year follow-ups.
RESULTS: Of the 1015 patients enrolled, 71% were male, aged 57.9±12 years. In addition, 68% had atherosclerotic cardiovascular disease (ASCVD), 25% of these patients achieved the LDL-C target, and 26% of the cohort were treated using combined lipid-lowering drugs, including statins.
CONCLUSION: The preliminary results of this cohort revealed that only one-fourth of ASCVD patients achieved LDL-C targets. Therefore, GULF ACTION shall improve our understanding of current dyslipidemia management and "guideline gaps" in the Arabian Gulf region.
METHODS: In-silico based drug designing approach was implemented for evaluating potential inhibitors against alpha-enolase based on their binding affinities, energy score and pharmacokinetics. Lipinski's rule of five (LRo5) and Egan's (Brain Or IntestinaL EstimateD) BOILED-Egg methods were executed to predict the best ligand for biological systems.
RESULTS: Molecular docking analysis revealed, Sodium (1,5-dihydroxy-2-oxopyrrolidin-3-yl)-hydroxy-dioxidophosphanium (SF-2312) as a promising inhibitor that fabricates finest attractive charges and conventional hydrogen bonds with S. pneumoniae alpha-enolase. Moreover, the pharmacokinetics of SF-2312 predict it as a therapeutic inhibitor for clinical trials. Like SF-2312, phosphono-acetohydroxamate (PhAH) also constructed adequate interactions at the active site of alpha-enolase, but it predicted less favourable than SF-2312 based on binding affinity.
CONCLUSION: Briefly, SF-2312 and PhAH ligands could inhibit the role of alpha-enolase to restrain plasminogen binding, invasion and progression of S. pneumoniae. As per our investigation and analysis, SF-2312 is the most potent naturally existing inhibitor of S. pneumoniae alpha-enolase in current time.
METHODS: The title amides (4a-j) were obtained by simple nucleophilic substitution reaction of dexibuprofen acid chloride with substituted amines in good yield and chemical structures were confirmed by FTIR, 1H NMR, 13C NMR and mass spectral data.
RESULTS: The brine shrimp lethality assay results showed that all of the synthesized compounds are non-toxic to shrimp larvae. The inhibitory effects on tumor growth were evaluated and it was observed that N-(2,5-dichlorophenyl)-2-(4-isobutylphenyl) propionamide (4e) and N-(2-chlorophenyl)-2-(4-isobutylphenyl) propionamide (4g) exhibited excellent antitumor activity compared to all other derivatives. The compound 4e bearing 2,5-dichloro substituted phenyl ring and 4g possesses 2-chloro substituted phenyl ring exhibited 100% inhibition of the tumor growth. The anticancer activity was evaluated against breast carcinoma cell line (MCF-7) and it was observed that derivative 4e exhibited excellent growth inhibition of cancer cells with IC50 value of 0.01±0.002 µm, which is better than the standard drugs. The docking studies against breast cancer type 1 susceptibility protein BRCA1 (PDBID 3K0H) exhibited good binding affinities, which are in good agreement with the wet lab results. The compounds 4e and 4g showed the binding energy values of -6.39 and -6.34 Kcal/mol, respectively. The molecular dynamic (MD) simulation was also carried out to evaluate the residual flexibility of the best docking complexes of compounds 4e and 4g. The MD simulation analysis assured that the 4e formed a more stable complex with the target protein than the 4g. The synthesized amide derivatives exhibited were devoid of gastrointestinal side effects and no cytotoxic effects against human normal epithelial breast cell line (MCF-12A) were found.
CONCLUSION: Based upon our wet lab and dry lab findings we propose that dexibuprofen analogue 4e may serve as a lead structure for the design of more potent anticancer drugs.
