The design, synthesis, and biological evaluation of a series of six HIV-1 protease inhibitors incorporating isosorbide moiety as novel P2 ligands are described. All the compounds are very potent HIV-1 protease inhibitors with IC50 values in the nanomolar or picomolar ranges (0.05–0.43 nM). Molecular docking studies revealed the formation of an extensive hydrogen-bonding network between the inhibitor
The novel benzimidazole hexahydrofuro[3,2-B]furan derivatives of the present invention are activators of AMP-protein kinase and may be useful in the treatment, prevention and suppression of diseases mediated by the AMPK-activated protein kinase. The compounds of the present invention may be useful in the treatment of Type 2 diabetes, hyperglycemia, metabolic syndrome, obesity, hypercholesterolemia, and hypertension.
Starting with isosorbide or isomannide several dianhydrohexitole-based benzamidines were synthesized as potential factor Xa inhibitors. The key steps for the synthesis of the bisbenzamidines were nucleophilic aromatic substitutions and Mitsunobu reactions to build up phenylethers. Another type of monobenzamidines had ortho-substituted biphenyl groups. Their synthesis necessitated an optimization of cross coupling procedures due to the great sterical hindrance of the ortho-substituent. The benzamidines showed biological activity against factor Xa and selectivity against other serine proteases.
从异山梨醇或异甘露醇开始,合成了几种基于双脱水己糖醇的苯甲脒作为潜在的 Xa 因子抑制剂。合成双苯甲脒的关键步骤是亲核芳香取代和光延反应以形成苯醚。另一种类型的单苯甲脒具有邻位取代的联苯基。由于邻位取代基的巨大空间位阻,它们的合成需要优化交叉偶联程序。苯甲脒显示出针对 Xa 因子的生物活性以及针对其他丝氨酸蛋白酶的选择性。

Isosorbide-2-benzyl carbamate-5-benzoate is a highly potent and selective BuChE inhibitor. Meanwhile, isosorbide-2-aspirinate-5-salicylate is a highly effective aspirin prodrug that relies on the salicylate portion to interact productively with human BuChE. By integrating the salicylate group into the carbamate design, we have produced isosorbide-2-benzyl carbamate-5-salicylate, an inhibitor of high potency (150 pM) and selectivity for human BuChE over AChE (666000) and CES2 (23000). Modeling and mutant studies indicate that it achieves its exceptional potency because of an interaction with the polar D70/Y332 cluster in the PAS of BuChE in addition to pseudosubstrate interactions with the active site.
