Ferroptosis is a new type of programmed cell death discovered recently and has been demonstrated to be involved in a number of human diseases such as ischemic stroke. Ferroptosis inhibitors are expected to have potential to treat these diseases. Herein, we report the identification of promethazine derivatives as a new type of ferroptosis inhibitors. Structure-activity relationship (SAR) analyses led
Ferroptosis是最近发现的一种新型的程序性细胞死亡,并且已证明其参与多种人类疾病,例如缺血性中风。预计铁锈病抑制剂具有治疗这些疾病的潜力。在本文中,我们报告了异丙嗪衍生物作为一种新型的肥大病抑制剂的鉴定。结构活性关系(SAR)分析导致发现最有效的化合物2-(1-(4-(4-(4-甲基哌嗪-1-基)苯基)乙基)-10 H-吩噻嗪(51),该化合物显示出在Estin诱导的HT1080细胞肥大症模型中,EC 50(最大最大有效浓度)值为0.0005μM。在MCAO(大脑中动脉闭塞)缺血性中风模型中,51表现出极好的治疗效果。该化合物还显示出有利的药代动力学性质,特别是渗透血脑屏障的良好能力。总体而言,51可能是治疗与勃起病相关疾病的有前途的先导化合物,值得进一步研究。
