their antimicrobial activity and it was demonstrated that 7H-benzochromenopyrimidine and derivatives of 14H-benzochromenotriazolopyrimidine exhibited the most promising antibacterial activities compared to the reference antimicrobial agents. The structure activity relationship (SAR) studies of the target compounds agreed with the in vitro essays and confirmed higher potent antimicrobial activity against
为了探索它们的抗菌活性,已经合成了三个新系列的色烯分子。该系列包括 2-取代的 14-(4-卤代苯基)-12-甲氧基-14H-苯并[h]色基[3,2-e][1,2,4]-三唑并[1,5-c]嘧啶 7a –o, 9-benzylideneamino-7-(4-halo-phenyl)-5-methoxy-8-imino-7H-benzo-[h]chromeno[2,3-d]pyrimidines 8a–b 和 3-ethoxycarbonyl-14 -(4-卤代苯基)-12-甲氧基-14H-苯并-[h]色基[3,2-e][1,2,4]三唑并[1,5-c]嘧啶-2-one衍生物12a-b . 这些新化合物的结构通过 IR、1H-和 13C-NMR 以及 MS 光谱证实。对这些新化合物的抗菌活性进行了体外评估,结果表明,与参考抗菌剂相比,7H-苯并铬并嘧啶和 14H-苯并铬并三唑并嘧啶的衍生物表
