Derivatives of two members of a new and unusual class of heterocycles, termed mesoionic purinone analogs, were synthesized and examined for in vitro antibacterial activity. Mesoionic thiazolo[3,2-a]pyrimidin-5,7-diones and mesoionic 1,3,4-thiadiazolo[3,2-a]pyrimidin-5,7-diones, which are isoconjugate with xanthine, were found to exhibit antibacterial activity against both Gram-negative and Gram-positive
合成了新的和异常的一类杂环的两个成员的衍生物,称为中离子嘌呤酮类似物,并检查了其体外抗菌活性。发现与黄嘌呤同缀合物的中离子噻唑并[3,2-a]嘧啶-5,7-二酮和中离子1,3,4-噻二唑并[3,2-a]嘧啶-5,7-二酮与黄嘌呤同构。对革兰氏阴性和革兰氏阳性生物均具有抗菌活性。几个中离子的1,3,4-噻二唑并[3,2-a]嘧啶-5,7-二酮对寻常变形杆菌和金黄色葡萄球菌具有显着水平的活性。
