compounds were found to competitively inhibit 6PGDH from T. brucei and sheep liver enzymes at micromolar concentrations. Six inhibitors belong to the (2R)-2-methyl-4-deoxy series (6, 8, 10, 12, 21, 24) and one is a (2R)-2-methyl-4,5-dideoxy analogue (29b). The 2,4-dideoxy analogues of 6PG did not inhibit both enzymes. The trypanocidal effect of the compounds was also evaluated in vitro against T. brucei rhodesiense
描述了三个系列的6-磷酸葡萄糖酸酯(6PG)类似物的合成和生物学评估。测试了6PG的(2R)-2-甲基-4,5-二脱氧,(2R)-2-甲基-4-脱氧和2,4-二脱氧类似物作为来自羊肝的6-磷酸葡萄糖酸脱氢酶(6PGDH)的抑制剂。还有布鲁氏锥虫,其中的酶是经过验证的药物靶标。在这三个系列的类似物中,发现七种化合物以微摩尔浓度竞争性地抑制布鲁氏杆菌和绵羊肝酶中的6PGDH。六种抑制剂属于(2R)-2-甲基-4-脱氧系列(6、8、10、12、21、24),一种是(2R)-2-甲基-4,5-二脱氧类似物(29b )。6PG的2,4-二脱氧类似物不抑制两种酶。还评估了化合物对T的锥虫杀螨作用。
