The synthesis of ten coumarin derivatives of 4‐hydroxycoumarin and various unsaturated ketones and aldehydes is described. The structures of the synthesized compounds were confirmed by IR, 1H‐NMR, and mass‐spectral data. Acute toxicity studies of the compounds were performed on mice by oral and intraperitoneal administration. A comparative pharmacological study of the in vivo anticoagulant effects
描述了 4-羟基香豆素和各种不饱和酮和醛的十种香豆素衍生物的合成。合成化合物的结构经IR、1H NMR和质谱数据证实。通过口服和腹膜内给药对小鼠进行化合物的急性毒性研究。衍生物相对于华法林的体内抗凝作用的比较药理学研究表明,这些化合物具有抗凝活性。化合物4-羟基-3-[1-苯基-2-(4'-氯苯甲酰基)乙基]-2H-1-苯并吡喃-2-2b、4-羟基-3-[1-(4-氟苯基)-3 -Oxobutyl] -2H-1-benzopyran-2-ones 3a 和 3, 3'-p-bromobenzylidene-bis- (4-hydroxy-2H-1-benzopyran-2-ones) 4b 显示出轻微的急性毒性和更大的毒性抗凝作用优于华法林。
