Abstract
Abstract In the present study, a novel generation of selective aldose reductase ALR2 inhibitors with significant hypoglycemic activities was designed and modulated based on rhodanine scaffold joined to an acetamide linker in between two lipophilic moieties. The synthesis of the novel compounds was accomplished throughout simple chemical pathways. Molecular docking was performed on B-cell membrane protein SUR1, aldehyde reductase ALR1 and aldose reductase ALR2 active sites. Compounds 10B, 11B, 12B, 15C, 16C, 26F and 27F displayed the highest hypoglycemic activities with 80.7, 85.2, 87, 82.3, 83.5, 81.4 and 85.3 % reduction in blood glucose levels, respectively. They were more potent than the standard hypoglycemic agent repaglinide with 65.4 % reduction in blood glucose level. Compounds 12B and 15C with IC50 0.29 and 0.35 µM were more potent than the standard ALR2 inhibitor epalrestat with IC50 0.40 µM. They were selective towards ALR2 over ALR1 134 and 116 folds, respectively. Molecular docking studies matched with the in-vitro and in-vivo results to elucidate the dual activities of both compounds 12B and 15C as potent antagonists for ALR2 over ALR1 and good agonists for the SUR1 protein.

Abstract Pim-1 kinase targeted recently has proved an essential goal of breast cancer therapy. We report the design, synthesis with full characterization analysis of pyrazolo[3,4-b]pyridine scaffold-based derivatives targeting Pim-1 kinase as anti-breast cancer agents. All the newly synthesized compounds were screened for their in vitro cytotoxic activity against two breast cancer cell lines MCF-7 and MDA-MB-231, and non-cancerous MCF-10A cells. Four derivatives notably, 17 and 19 exhibited a re...

N-Alkyl-2-(substitutedbenzamido) benzamides and methyl 2-(2-(substitutedbenzamido) benzamido) alkanoates were prepared by either the reaction of amines or amino acid esters with benzoxazine derivatives or the DCC coupling of 2-substitutedbenzamido benzoic acid with amines or amino acid esters. Methyl 2-(2-(4-chlorobenzamido)benzamido alkanoates were used as the key intermediate for the preparation of dipeptide-coupled benzamides via azide and DCC coupling methods. The investigated compounds were...

Abstract There is a pressing need to discover and develop novel drugs against cancer. With the new era of bioinformatics, which integrates different aspects, drug development has been tremendously improved. Recently, extensive research was directed towards the rational modification of steroid molecules against different disease especially cancer. Moreover, heterocyclic steroid derivatives have shown a lot of different biological activities such as antimicrobial, anti-inflammatory, and anti-cance...

Abstract Novel non-sulfonylureas derivatives bearing an acetamide linker between a spirohydantoin scaffold and a phenyl ring were prepared and their hypoglycemic activity was estimated in vivo . Their abilities to discriminate in vitro between aldehyde reductase (ALR1) and aldose reductase (ALR2) were determined. The molecular docking and the in silico prediction studies were performed to rationalize the obtained biological results and to predict the physicochemical properties and drug-likeness ...

Abstract Novel derivatives of spiroimidazolidinedione were synthesized and evaluated as hypoglycemic agents through binding to sulfonylurea receptor 1 (SUR1) in pancreatic beta-cells. Their selectivity index was calculated against both aldehyde reductase (ALR1) and aldose reductase (ALR2). Aldehyde reductase is a key enzyme in the polyol pathway that is involved in the etiology of the secondary diabetic complications. All structures were confirmed by microanalysis and by IR, 1H NMR, 13C NMR and ...

Abstract Human aldose reductase (AKR1B1, AR) is a key enzyme of the polyol pathway, catalyzing the reduction of glucose to sorbitol at high glucose concentrations, as those found in diabetic condition. Indeed, AKR1B1 overexpression is related to diabetes secondary complications and, in some cases, with cancer. For many years, research has been focused on finding new AKR1B1 inhibitors (ARIs) to overcome these diseases. Despite the efforts, most of the new drug candidates failed because of their p...

Abstract In the present study, the pharmacophore integration methodology provided an efficient access to a new library of thioxothiazolidinone–sulfonate conjugates ( 8a–r ) from easily available synthetic precursors. The approach was excellently high yielding with flexible structural sites for chemical modifications. The designed hybrid scaffolds were assessed for aldehyde/aldose reductase inhibition activities. The results for the in vitro bioassays were promising with the identification of com...
