Abstract
A high-throughput assay was developed to identify inhibitors of cystathionine β-synthase (CBS), which is one of three key enzymes involved in HS biosynthesis. Screening of 6491 natural compounds identified several selective CBS inhibitors, which suppressed the proliferation of HT29 cancer cells, with IC values of less than 10 μM.
摘要
开发了一种高通量检测方法来鉴定胱硫醚β-合酶（CBS）的抑制剂，CBS是参与硫化氢生物合成的三种关键酶之一。对6491种天然化合物进行筛选，鉴定出几种选择性CBS抑制剂，这些抑制剂能抑制HT29癌细胞的增殖，其半数抑制浓度（IC）值小于10μM。
