A series of 43, 3a,4-dihydro-3H-indeno[1,2-c]pyrazole-2-carboxamide/carbothioamide analogues (D01-D43) were analysed using Petra, Osiris, Molinspiration and ALOGPS (POMA) to identify pharmacophore, toxicity prediction, lipophilicity and bioactivity. All the compounds were evaluated for anti-HIV activity. 3-(4-Chlorophenyl)-N-(4-fluorophenyl)-6,7-dimethoxy-3a,4-dihydro-3H-indeno[1,2-c]pyrazole-2-carboxamide (D07) was found to be the most
