A series of new thieno[2,3-d]pyrimidin-4(3H)-one derivatives were synthesized and evaluated for their activity against four gram-positive and four gram-negative bacterial and eight fungal species. The majority of the compounds exhibited excellent antimicrobial and antifungal activity, being more potent than the control compounds. Compound 22, bearing a m-methoxyphenyl group and an ethylenediamine side
合成了一系列新的噻吩并 [2,3 - d ]pyrimidin-4(3 H )-one 衍生物,并评估了它们对四种革兰氏阳性菌和四种革兰氏阴性菌和八种真菌物种的活性。大多数化合物表现出优异的抗微生物和抗真菌活性,比对照化合物更有效。合成化合物22,轴承米甲氧基苯基基团和C-2的噻吩并嘧啶核的锚定乙二胺侧链,是与在0.05-0.13毫米范围内的MIC值广泛的抗微生物活性的最有效的抗菌化合物,为6到15fold比对照、链霉素和氨苄青霉素更有效。此外,化合物14和15其中承担一个p -氯苯基和米甲氧基苯基组,分别和共享2-(2- mercaptoethoxy)乙-1-醇侧链显示出最好的抗真菌活性,是10-15倍酮康唑或联苯苄唑与MIC更有效值分别为 0.013-0.026 和 0.027 mM。特别是在化合物15的情况下,低 MIC 值伴随着范围从 0.056-0.058 mM 的出色 MFC 值。对
