    吩噻嗪类似物的抗铁凋亡活性:氧化应激相关疾病的新治疗策略
    摘要:
    铁死亡是一种铁催化的非凋亡调节性坏死形式,与各种疾病相关的病理性细胞死亡有关,包括神经退行性疾病(例如弗里德赖希共济失调 (FRDA)、阿尔茨海默病和帕金森病)、中风和脑外伤受伤。最近,我们发现亲脂性亚甲蓝 (MB) 和亚甲紫 (MV) 类似物除了在培养的 FRDA 细胞中具有抗氧化活性外,还促进了 frataxin 水平和线粒体生物发生的增加。目前,我们报告了一系列有效抑制铁死亡的亲脂性吩噻嗪类似物的合成。最有前途的化合物 ( 1b – 5b) 与亲本吩噻嗪相比,对erastin 和RSL3 诱导的铁死亡细胞具有更好的保护作用。这些类似物与 ferrostatin-1 (Fer-1) 和 liproxstatin-1 (Lip-1) 具有同等或更好的效力,它们是迄今为止描述的这种受调节细胞死亡的最有效抑制剂。它们代表了在相关铁死亡驱动的疾病模型(如 FRDA)中具有治疗潜力的新型先导化合物。

    公开(公告)日:2018-07-17
    A process for continuously preparing the tert-butyl ester of an aliphatic C1-C4 carboxylic acid comprises: a) the reaction of an aliphatic C1-C4 carboxylic acid with isobutene in the presence of an acidic catalyst to give an esterification mixture (G1); b) the partial evaporation of the esterification mixture (G1), giving a liquid first high boiler phase (SPh1) comprising the acidic catalyst, and a first vapor (B1) comprising tert-butyl ester; c) the fractional condensation of the first vapor (B1) by partially condensing the first vapor (B1) at a first pressure and a first temperature and obtaining a first condensate (K1), partially condensing the uncondensed second vapor (B2) at a second pressure and a second temperature and obtaining a second condensate (K2), the first temperature being 0 to 45° C. below the condensation temperature of the tert-butyl ester at the first pressure and the second temperature being 45 to 80° C. below the condensation temperature of the tert-butyl ester at the second pressure, with the proviso that the second temperature is at least 5° C. below the first temperature; and d) the combination of the first condensate (K1) and the second condensate (K2) and the feeding to a combined workup, and recycling of the third vapor (B3) not condensed at the second temperature into step a). The process allows the preparation of the tert-butyl ester of an aliphatic C1-C4 carboxylic acid by reaction of the carboxylic acid with isobutene, with isolation of unconverted isobutene from the esterification mixture in an energetically favorable manner and with an improved degree of removal.
