The synthesis and inhibitory potencies against botulinum neurotoxin serotype A light chain (BoNT/A LC) using in vitro HPLC based enzymatic assay for various steroidal, benzothiophene, thiophene, and adamantane 4-aminoquinoline derivatives are described. In addition, the compounds were evaluated for the activity against BoNT/A holotoxin in mouse embryonic stem cell derived motor neurons. Steroidal derivative
描述了使用基于体外HPLC的酶法测定各种甾体,苯并噻吩,噻吩和金刚烷4-氨基喹啉衍生物对A型肉毒杆菌神经毒素轻链(BoNT / A LC)的合成和抑制能力。另外,评估了化合物在小鼠胚胎干细胞衍生的运动神经元中对BoNT / A全毒素的活性。甚至在中毒后30分钟给药,类固醇衍生物16也显示出显着的保护作用(高达89%的未裂解SNAP-25)。这似乎是LC抑制剂在暴露后模型中拮抗小鼠胚胎干细胞衍生的运动神经元(mES-MNs)中BoNT中毒的第一个例子。口服16 高达600 mg / kg,qd的小鼠具有良好的耐受性,尽管在该剂量下未达到足够的未结合药物水平,但体外ADMET的良好结果有力地支持了该系列的进一步工作。
