Two series of 2-adamantyl/adamantylmethyl-5-aryl-1,3,4-oxadiazoles (4a-l and 5a-l) were synthesized by
cyclodehydration of adamantan-1-carboxylic acid/adamantylacetic acid with various aryl hydrazides (3a-l) in the presence
of POCl3. The synthesis was supported by spectroanalytical techniques and verified further by crystal structure determination
of compounds 4e and 5k. The synthesized compounds were screened for their inhibitory activity against HIV-1 and
HIV-2 in MT-4 cells. Compound 5b exhibited a moderate activity in vitro for the replication of both virus types, suggesting
for further structural modification as a new lead in the development of an antiviral agent.
合成了两系列的2-氨基-邻氨基-5-芳基-1,3,4-噁二唑(4a-l和5a-l),通过在POCl3的存在下,将亚甲基氨基-1-羧酸/亚甲基氨基乙酸与各种芳基肼(3a-l)进行环脱水反应。合成过程得到了光谱分析技术的支持,并通过化合物4e和5k的晶体结构测定进一步验证。合成的化合物在MT-4细胞中筛选其对HIV-1和HIV-2的抑制活性。化合物5b在体外对两种病毒类型的复制表现出适度活性,建议对其进行进一步的结构修饰,以作为开发抗病毒药物的新线索。
