using standard chemotherapy. We previously demonstrated that a piperidinol derivative, named PIPD1, is an efficient molecule both against M. abscessus and Mycobacterium tuberculosis, the agent of tuberculosis, by targeting the mycolic acid transporter MmpL3. These results prompted us to design and synthesize a series of piperidinol derivatives and to determine the biological activity against M. abscessus
(BChE) with IC50 values in the low micromolar range. Kinetic studies on the most potent cholinesterase (ChE) inhibitors within the series showed a mixed-type inhibition mechanism on both enzymes. Also, the docking studies indicated that the compounds inhibit ChEs by dual binding site (DBS) interactions. Notably, tacrine–donepezil hybrids also exhibited significant neuroprotection against H2O2-induced
合成了一系列他克林-多奈哌齐杂化物作为潜在的多功能抗阿尔茨海默病(AD)化合物。为此,将他克林和多奈哌齐的苄基哌啶部分与腙基团融合,以获得他克林-多奈哌齐杂合体的小型文库。与设计一致,所有化合物均表现出对乙酰胆碱酯酶 (AChE) 和丁酰胆碱酯酶 (BChE) 的抑制活性,IC 50值在低微摩尔范围内。该系列中最有效的胆碱酯酶 (ChE) 抑制剂的动力学研究表明,这两种酶具有混合型抑制机制。此外,对接研究表明这些化合物通过双结合位点 (DBS) 相互作用抑制 ChE。值得注意的是,他克林-多奈哌齐杂合体在接近其对 ChE 的 IC 50值的浓度下,对分化的人神经母细胞瘤 (SH-SY5Y) 细胞系中 H 2 O 2诱导的细胞死亡也表现出显着的神经保护作用,并表现出高至中等的血脑屏障(BBB) 人脑微血管内皮细胞 (HBEC-5i) 的通透性。此外,该化合物对人肝细胞癌细胞系(HepG2)和

This Letter describes the first account of the synthesis and SAR, developed through an iterative analogue library approach, of analogues of the highly selective M1 allosteric agonist TBPB. With slight structural changes, mAChR selectivity was maintained, but the degree of partial M1 agonism varied considerably.
