A novel series of phenyl hydrazone bearing pyrazole and pyrimidine hybrid compounds has been designed using the molinspiration toolkit based on Lipinski's rule of five and developed via sequential reactions starting from the diazotization of different anilines and further active methylation with acetyl acetone, ethyl acetoacetate and ethyl cyanoacetate to generate hydrazono derivatives. The target hybrid compounds were synthesized on cyclisation of the resulting hydrazono derivatives with hydrazine, phenyl hydrazine and urea. These molecules have been subsequently tested for anti-HIV activity using TZM-bl cell lines. The MTT assay was also carried out for the cytotoxicity determination of the active compounds. Further, to exemplify the key structural features of the molecules, a molecular docking analysis of the most active compounds was performed at the NNIBP of the HIV-RT protein. The antibacterial activity of the target compounds was also determined against a panel of four Gram-positive and four Gram-negative human pathogens. All molecules showed a potent anti-HIV activity along with a prominent inhibition of bacterial organisms.
一种新的系列含有吡唑和嘧啶杂合化合物的苯肼酮已被设计,这一设计基于Lipinski五条规则,并通过从不同苯胺的重氮化反应开始,随后与乙酰乙酸、乙基乙酰乙酸和乙基氰乙酸的活性甲基化反应生成肼酮衍生物。目标杂合化合物是在生成的肼酮衍生物与肼、苯肼和尿素环化反应后合成的。这些分子随后在TZM-bl细胞系中进行了抗HIV活性测试。此外,还进行了MTT法以确定活性化合物的细胞毒性。为了说明这些分子的关键结构特征,还对最活跃化合物在HIV-RT蛋白的NNIBP进行了分子对接分析。目标化合物的抗菌活性也针对四种革兰氏阳性菌和四种革兰氏阴性人类病原体进行了检测。所有分子均显示出强效的抗HIV活性以及显著的细菌抑制作用。
