Pyridindolol

细菌代谢物；在酸性条件下（2µg/ml浓度下）可抑制50%的中性β-半乳糖苷酶，但在中性条件下不会抑制；对从牛肝中分离的β-半乳糖苷酶具有选择性，优于从人、牛、猪和大鼠组织中分离的β-半乳糖苷酶以及从产气荚膜梭菌、链霉菌和流感病毒H3N2株中分离的唾液酸酶（所有药物的IC50均为>250µg/ml）。A bacterial metabolite; inhibits neutral β-galactosidase by 50% under acidic, but not neutral, conditions at 2 µg/ml; selective for β-galactosidase isolated from bovine liver over β-galactosidases isolated from human, bovine, pig, and rat tissues and sialidases isolated from C. perfringens, Streptomyces, and the H3N2 strain of influenza virus (IC50s = >250 µg/ml for all).分子式C14H14N2O3分子量258.3OC[C@@H](C1=C2C(C3=CC=CC=C3N2)=CC(CO)=N1)O
