thiocarbazones, 1,3,4-oxadiazoles, and 1,3,4-thiadiazoles bearing coumarin and pyrazole moiety have been synthesized. The new synthesized compounds were screened in vitro for their antimicrobial and antioxidant activities. Preliminary studies showed that among the synthesized new compounds, chloro-substituted thiosemicarbazone showed excellent activities against all tested organisms; at the same time, methyl
已经合成了一系列带有香豆素和吡唑部分的缩氨基脲、硫脲、1,3,4-恶二唑和1,3,4-噻二唑。新合成的化合物在体外进行了抗微生物和抗氧化活性筛选。初步研究表明,在合成的新化合物中,氯代氨基硫脲对所有受试生物均表现出优异的活性;同时,甲基取代的氨基硫脲对大肠杆菌表现出更大的活性。氯取代的 1,3,4-恶二唑和 1,3,4-噻二唑表现出更强的 DPPH 和羟基自由基清除能力。分子对接研究表明,与 SOD(超氧化物歧化酶)相比,1,3,4-恶二唑和 1,3,4-噻二唑与 CAT(过氧化氢酶)和 GPx(谷胱甘肽过氧化物酶)的相互作用更好。
