Reactions of N‐(quinazolin‐4‐yl)amidines and their amide oximes with hydroxylamine hydrochloride gave cyclization products that were formed by an initial ring cleavage of the pyrimidine component followed by a ring closure formation of 1,2,4‐oxadiazole to give N‐[2‐([1,2,4]oxadiazol‐5‐yl)phenyl]formamide oximes. All isolated products were evaluated for in vitro inhibitory activity on the formation
的反应ñ - (喹唑啉-4-基)脒和与盐酸羟胺它们的酰胺肟,得到由嘧啶成分的初始环切割被形成的环化产物,随后的-1,2,4-恶二唑,得到环闭合形成N- [2-([[1,2,4]恶二唑-5-基)苯基]甲酰胺肟。评价所有分离的产物对戊糖苷形成的体外抑制活性,戊糖苷是代表性的高级糖基化终产物之一。一些产品显示出对戊糖苷形成的显着抑制活性。J.杂环化学。(2011)。
