Structure-based drug design was utilized to develop novel, 1-hydroxy-2-naphthoate-based small-molecule inhibitors of Mcl-1. Ligand design was driven by exploiting a salt bridge with R263 and interactions with the p2 pocket of the protein. Significantly, target molecules were accessed in just two synthetic steps, suggesting further optimization will require minimal synthetic effort. Molecular modeling
基于结构的药物设计用于开发新型的基于Mcl-1的1-羟基-2-萘甲酸的小分子抑制剂。通过利用具有R263的盐桥以及与蛋白质p2口袋的相互作用来驱动配体设计。重要的是,目标分子仅需两个合成步骤即可进入,这表明进一步的优化将需要最少的合成工作。使用通过配体竞争饱和位点识别(SILCS)方法进行分子建模,以定性指导配体设计,并开发定量模型来确定抑制剂对Mcl-1和Bcl-2相对Bcl-x L的结合亲和力以及对与两种蛋白质结合的特异性。结果表明,最有利的结合配体在p2口袋中的疏水相互作用占主导地位(3bl:K i =31nM)。化合物对Mcl-1的选择性是Bcl-x L的19倍。抑制剂的选择性是由与Mcl-1和Bcl-x L中较深的p2口袋相互作用而驱动的。本发明化合物的基于SILCS的SAR代表了开发Mcl-1特异性抑制剂的基础,所述Mcl-1特异性抑制剂具有治疗广泛的实体瘤和血液系统癌症,包括急性髓细胞白血病的潜力。

The stereochemistry of the cobalt(II) chloride catalysed opening of cinnamoyl epoxides with N-substituted anilines is controlled by the para substituent of the aromatic ring attached to nitrogen atom. Thus the secondary amine having a para methoxy group cleaves the epoxide to afford the corresponding anti amino alcohol as the major product whereas amines containing para chloro, bromo, methyl or hydrogen
