a compound with in vivo efficacy, which was hampered by poor solubility and genotoxicity. The work on the original scaffold failed to lead to developable compounds, so an extensive scaffold-hopping exercise involving medicinal chemistry design, in silico profiling, and subsequent synthesis was utilized, leading to the preclinical candidate. The compound was shown to act via proteasome inhibition, and
内脏利什曼病 (VL) 是一种严重影响东非、亚洲和南美洲大片地区的寄生虫感染,迫切需要新的治疗方法。我们之前报道了 GSK3494245/DDD01305143 ( 1 ) 作为 VL 的临床前候选者的发现,并且在本文中,我们报告了导致其鉴定的药物化学程序。对表型筛选的命中进行了优化,以提供具有体内功效的化合物,但由于溶解度差和遗传毒性而受到阻碍。原始支架上的工作未能产生可开发的化合物,因此在计算机上进行了涉及药物化学设计的广泛支架跳跃练习分析和随后的合成被利用,导致临床前候选人。该化合物被证明通过蛋白酶体抑制起作用,我们报告了将不同支架建模成冷冻电镜结构以及这对我们理解该系列的结构-活性关系的影响。
