  Discovery of N-[[1-[2-(tert-butylcarbamoylamino)ethyl]-4-(hydroxymethyl)-4-piperidyl]methyl]-3,5-dichloro-benzamide as a selective T-type calcium channel (Cav3.2) inhibitor

  摘要：

  The T-type calcium channel inhibitor Mibefradil was reported to protect the heart from atrial remodeling, a key process involved in the development of atrial fibrillation and arrhythmias. Mibefradil is not a selective T-type calcium channel inhibitor and also affects the function of different ion channels. Our aim was to develop a selective T-type calcium channel inhibitor to validate the importance of T-type-related pharmacology in atrial fibrillation. Structural optimisation of a previously disclosed hit series focussed on minimising exposure to the central nervous system and improving pharmacokinetic properties, while maintain adequate potency and selectivity. This resulted in the design of N-[[1-[2-(tert-butylcarbamoylamino)ethyl]-4-(hydroxymethyl)-4-piperidyl]methyl]-3,5-dichloro-benzamide, a novel, selective, peripherally restricted chemical probe to verify the role of T-type calcium channel inhibition on atrial fibrillation protection.

  structure-metabolism relationship study (SMR). The compounds showed an excellent safety profile, favourable physicochemical characteristics, and the required metabolic stability. A cross-resistance study confirmed the viral capping machinery (nsP1) to be the viral target of these compounds. This study identified 31b and 34 as potent, safe, and stable lead compounds for further development as selective

  基孔肯雅病毒 (CHIKV) 在全球范围内重新出现、与之相关的高发病率以及可用疫苗或抗病毒治疗的缺乏，使得开发一种有效的 CHIKV 抑制剂非常迫切。因此，基于之前报道的 CHVB 化合物1b进行了广泛的先导化合物优化，并对报道的合成路线进行了优化——在显着更短的合成和后处理时间内提高了总产率。设计、合成了数百种类似物，并研究了它们的抗病毒活性、生理化学和毒理学特征。进行了广泛的构效关系研究 (SAR)，主要关注支架变化的组合，并揭示了有效抗 CHIKV 抑制的关键化学特征。此外，对这些化合物进行了彻底的 ADMET 研究：筛选了这些化合物的水溶性、亲脂性、在 CaCo-2 细胞中的毒性以及可能的 hERG 通道相互作用。此外，还评估了 55 种类似物在人肝微粒体 (HLM) 中的代谢稳定性，从而开展了结构-代谢关系研究 (SMR)。这些化合物表现出优异的安全性、良好的理化特性和所需的代谢稳定性。交叉耐药性研究证实病毒加帽机制
