N,N'-二卤代苯基-4-甲氧基-1,3-苯二磺酰胺类化合物的设计、合成及体外抗血小板聚集活性评价

Design, synthesis of novel N, N'-bis-(halogenophenyl)-4-methoxybenzene-1, 3-disulfonamides and evaluation of their anti-platelet aggregation activity

依据药物化学结构设计中拼合和等排原则,拼合抗血小板聚集药物吡考他胺(picotamide)和利曲他班(linotroban)的结构,用磺酰基代替甲酰基,设计合成了N,N'-二卤代苯基-4-甲氧基-1,3-苯二磺酰胺系列化合物(4a^4m、5a^5n),各化合物的结构由IR、1H NMR和HR-MS光谱确证。以吡考他胺为阳性对照药,采用Born比浊法检测目标化合物抗二磷酸腺苷(ADP)诱导的体外抗血小板聚集活性,结果显示其中12个化合物(4b、4f、4l、5b、5d^5g、5j、5k、5m和5n)对ADP诱导的血小板聚集的抑制活性优于阳性对照药吡考他胺。此外,初步探讨了目标化合物的构效关系。

Combining the structural features of picotamide and linotroban, a series of N, N ＇-bis-（halogenophenyl）-4-methoxybenzene-1, 3-disulfonamides were designed and synthesized on the basic principles of drug design. The structures of target compounds were confirmed by IR, 1H NMR and HR-MS, and the in vitro antiplatelet aggregation activity was evaluated by Born turbidimetric method with adenosine diphosphate（ADP） as the platelet aggregation inducers. The assay results showed that twelve compounds（4b, 4f, 4l, 5b, 5d-5g, 5j, 5k, 5m and 5n） were found to have superior anti-platelet aggregation activities than the positive drug picotamide. The preliminary structure-activity relationship（SAR） has been explored.
