Warfarin (Coumafene) 是一种维生素 K 拮抗剂,它通过阻断维生素 K 的作用而起作用,维生素 K 是肝脏中凝血因子合成所必需的。Warfarin 通过抑制γ -谷氨酰羧化酶来阻断维生素 K 的作用,γ -谷氨酰羧化酶负责凝血因子中谷氨酸残基的羧化。这阻止了功能性凝血因子的产生,从而产生抗凝作用。
Apramycin(Nebramycin II) is an aminoglycoside antibiotic used in veterinary medicine. IC50 value:Target: Apramycin stands out among aminoglycosides for its mechanism of action which is based on blocking translocation and its ability to bind also to the eukaryotic decoding site despite differences in key residues required for apramycin recognition by the bacterial target. The drug binds in the deep groove of the RNA which forms a continuously stacked helix comprising non-canonical C.A and G.A base pairs and a bulged-out adenine. The binding mode of apramycin at the human decoding-site RNA is distinct from aminoglycoside recognition of the bacterial target, suggesting a molecular basis for the actions of apramycin in eukaryotes and bacteria.
