razin‐1‐yl)acetamide (BOAP‐AM6) and N‐(4‐butyl‐3‐oxo‐3,4‐dihydro‐2H‐benzo[b][1,4]oxazin‐7‐yl)‐2‐(4‐(4‐fluorophenyl)piperazin‐1‐yl)acetamide (BOAP‐AM21) as platelet aggregation inhibitors with an IC50 of 8.93 and 8.67 μM, respectively, as potent as the positive control aspirin. A combination of structure–activity relationships studies and molecular modeling revealed that the molecule BOAP‐AM6 interacted
血管内血栓形成不当是导致工业化世界死亡的主要原因。凝血酶激活的血小板聚集可能与血栓形成密切相关。基于我们对1,4-苯并恶嗪-3(4 H)-one对理想的血小板聚集抑制活性的药理作用研究,我们确定了N-(4-乙基-3-氧代-3,4-二氢-2 H -苯并[ b ] [1,4]恶嗪-7-基)-2-(4-甲基哌嗪-1-基)乙酰胺(BOAP-AM6)和N-(4-丁基-3-氧代-3,4-二氢-2 H-苯并[ b ] [1,4]恶嗪-7-基)-2-(4-(4-氟苯基)哌嗪-1-基)乙酰胺(BOAP-AM21)作为血小板聚集抑制剂,IC 50分别为8.93和8.67μM,与阳性对照阿司匹林一样有效。结构-活性关系研究与分子建模相结合,发现分子BOAP-AM6通过氢键与GPIIb / IIIa受体结合位点的氨基酸残基TYR166和ARG214相互作用,而化合物BOAP-AM21作用于氨基酸残基ASN215和
