在过去的几十年中,组胺H 3受体由于参与了神经退行性疾病等多种疾病的病理生理学而在药物研究中受到广泛关注。在这种情况下,阻断这些受体对于此类疾病的进展至关重要。在目前的研究中,通过利用支架跳跃药物设计策略设计了新型组胺 H 3受体配体。我们根据 ADME 特性、药物相似性以及毒性特征检查了设计的分子。此外,还进行了分子对接和动力学模拟研究以分别预测结合模式和结合自由能计算。在设计的结构中,我们选择了化合物d2及其去甲基化衍生物作为合成和亲和力测量的例子。合成分子的体外结合试验表明,d2 在放射性配体置换试验中对 hH 3 R 的结合亲和力低于去甲基化形式(K i = 12.53 μM )。新设计的化合物避免了因扩展计算机和实验研究而产生的任何毒性预测因子,可以为组胺 H 3 R 拮抗剂提供另一种支架,用于进一步的构效关系研究。

The C(sp3)–C(sp3) cross-coupling of alkyl halides with alkyl tosylates has been developed by employing a combination of nickel and nucleophilic cobalt catalysts in the presence of a manganese reductant. This method provides a straightforward route to a diverse set of not only secondary–primary but also primary–primary C(sp3)–C(sp3) linkages under mild conditions without using alkyl-metallic reagents
