  选择性组蛋白脱乙酰酶 1 和 2 抑制剂的发现：筛选通过点击化学构建的聚焦文库、动力学结合分析和生物学评价

  摘要：

  组蛋白脱乙酰酶 1 和 2 (HDAC1/2) 抑制剂可作为探索异构体生物学功能的工具以及作为癌症和神经退行性疾病的治疗剂。为了发现有效的选择性抑制剂，我们筛选了使用点击化学合成的重点库，并获得了KPZ560作为 HDAC1/2 选择性抑制剂。动力学结合分析表明， KPZ560通过两步缓慢结合机制抑制 HDAC2。在细胞测定中， KPZ560诱导组蛋白乙酰化呈剂量和时间依赖性增加，并显示出有效的乳腺癌细胞生长抑制活性。此外，基因表达分析表明， KPZ560的两步缓慢结合抑制调节与细胞增殖和 DNA 损伤相关的基因的表达。 KPZ560还诱导 Neuro-2a 细胞的神经突生长，并增加小鼠颗粒神经元树突的棘密度。 KPZ560等邻氨基苯胺独特的两步缓慢结合特性使其成为治疗剂的有趣候选者。

  Sodium glucose co-transporter 1 (SGLT1) plays a dominant role in the absorption of glucose in the gut and is considered a promising target in the development of treatments for postprandial hyperglycemia. A series of 4-benzyl-1H-pyrazol-3-yl beta-D-glucopyranoside derivatives have been synthesized, and its inhibitory activity toward SGLTs has been evaluated. By altering the substitution groups at the 5-position of the pyrazole ring, and every position of the phenyl ring, we studied the structure-activity relationship (SAR) profiles and identified a series of potent and selective SGLT1 inhibitors. Representative derivatives showed a dose-dependent suppressing effect on the escalation of blood glucose levels in oral mixed carbohydrate tolerance tests (OCTT) in streptozotocin-nicotinamide-induced diabetic rats (NA-STZ rats).

  Cationic antimicrobial polymers have been synthesized by a bulk addition polymerization of a nucleophilic agent comprising two tertiary amines and an electrophilic agent that comprises two leaving groups and an aromatic ring between the leaving groups. The reaction solvent for the polymerization is chosen to allow precipitation of the cationic polymer at the polymerization temperature, thereby limiting molecular weight. Quaternization and polymerization occur concurrently. The cationic polymers can be highly active against Gram-negative and Gram-positive microbes, and/or fungi. The cationic polymers can also be non-hemolytic and non-cytotoxic at the effective concentration against the microbes.
