截瘫是非凋亡性细胞死亡,其特征在于大量内质网(ER)或线粒体来源的液泡。与依赖凋亡的抗癌药物相比,诱发上pt裂可为化疗耐药性肿瘤的治疗提供显着优势。由于某些天然生物碱可诱导麻痹性细胞死亡,因此合成了一系列新的苯并[ a ]喹诺唑烷衍生物,并对其抗增殖活性和诱导细胞质空泡的能力进行了分析。结构优化导致了强效化合物22b的鉴定,该化合物在体内外抑制癌细胞的增殖,并极大地促进了类麻痹样细胞的死亡并诱导了caspase依赖性细胞凋亡。进一步调查发现22b介导的空泡作用源自持续的内质网应激和LC3B的上调。因此,由苯并[ a ]喹啉嗪衍生物诱导的截瘫代表了癌症化学疗法的另一种策略。

airways. From a systematic variation of the capsazepine structure, divided into four regions, SARs were established. This paper concerns the chlorination of the A-ring as well as the replacement of the catechol with bioisosteric groups. It is revealed that chlorination of the A-ring has a profound effect on activity. Moreover, di-chlorination of the 6,7-dihydroxy-1,2,3,4-tetrahydroisoquinoline structure
Novel thiazole- and isoquinoline-containing compounds are presented that are useful for treating and/or preventing broad-spectrum viral infections. Methods of treating and/or preventing broad-spectrum viral infections are also presented. These compounds have shown inhibition of HCMV, influenza viruses, Zika virus, BK Virus and RSV replication in cell-based assays.
