A novel class of heat shock protein 90 (Hsp90) inhibitors was discovered by high-throughput screening and was subsequently optimized using a combination of structure-based design, parallel synthesis, and the application of medicinal chemistry principles. Through this process, the biochemical and cell-based potency of the original HTS lead were substantially improved along with the corresponding metabolic
通过高通量筛选发现了一类新型的热休克蛋白90(Hsp90)抑制剂,随后结合基于结构的设计,平行合成和药物化学原理的应用对其进行了优化。通过此过程,原始HTS铅的生化和基于细胞的效力以及相应的代谢稳定性得到了显着改善。这些努力最终以鉴定出显示出所需的PK / PD关系,在黑素瘤A2058异种移植肿瘤模型中具有显着功效以及有吸引力的DMPK谱的发展候选者(化合物42)的鉴定为最终。
