requirements for calcium channel blocking activity of the known dihydropyridines and dihydropyrimidines calcium channel blockers. The newly synthesized compounds were evaluated as antagonists for CaV1.2 and CaV3.2 using the whole-cell patch clamp technique. Seven compounds (4b, 4c, 6c, 9, 13c, 13e and 17b) showed promising dual calcium channel blocking activity and three compounds (13b, 14b and 17a) were
设计并合成了在位置3具有各种亲脂药效团和功能的新的二氢嘧啶。设计新化合物的基本框架以维持已知的二氢吡啶和二氢嘧啶钙通道阻滞剂对钙通道阻滞活性的主要结构要求。使用全细胞膜片钳技术将新合成的化合物评估为CaV1.2和CaV3.2的拮抗剂。七种化合物(4b,4c,6c,9、13c,13e和17b)显示出有希望的双重钙通道阻断活性,三种化合物(13b,14b和17a)对Cav3.2具有选择性。使用Molinspiration和Molsoft软件评估了它们的药物相似性。它们的理化性质和药代动力学特征建议将它们视为药物样候选物。
