atherosclerosis, and arthritis, MMPs represent a valuable target for the development of new therapeutics and diagnostic tools. We herein present the chiral pool syntheses, in vitro evaluation, and SAR studies of a series of d- and l-proline- as well as of (4R)-4-hydroxy-l-proline-derived MMP inhibitors possessing general formula 1. Some of the synthesized hydroxamic acids were found to be potent MMP inhibitors
由于基质金属蛋白酶(MMP)活性失调与多种病理生理过程(如癌症,动脉粥样硬化和关节炎)相关,因此MMP代表了开发新疗法和诊断工具的重要目标。我们在此介绍了一系列具有通式1的d-和l-脯氨酸以及(4 R)-4-羟基-1-脯氨酸衍生的MMP抑制剂的手性库合成,体外评估和SAR研究。发现一些合成的异羟肟酸是有效的MMP抑制剂,IC 50值在纳摩尔范围内,也表明对其他测试的Zn 2+没有脱靶作用。依赖的金属蛋白酶(ADAM和meprins)。利用(2 S,4 S)构型的4-羟基脯氨酸衍生物4(一种MMP-13的选择性皮摩尔抑制剂)的结构,成功合成了放射性标记的对应物[ 18 F] 4。评估了放射性示踪剂在小鼠中的生物分布及其血清稳定性,以评估其作为靶向MMP-13的PET显像剂的潜在用途。
