  Synthesis and anticonvulsant activity of 3a,4-dihydro-3H-indeno[1,2-c]pyrazole-2-carboxamide/carbothioamide analogues

  摘要：

  A series of fourteen 3a,4-dihydro-3H-indeno[1,2-c]pyrazole-2-carboxamide/carbothioamide analogues were synthesized and evaluated for anticonvulsant activity according to the Antiepileptic Drug Development Programme (ADD) protocol. Some of the synthesized compounds showed significant activity in minimal clonic seizure model (6 Hz psychomotor seizure test). 3-(4-Fluorophenyl)-N-(4-bromophenyl)-6,7-dimethoxy-3a,4-dihydro-3H-indeno[1,2-c] pyrazole-2-carboxamide (4c) was found to be the most active compound of the series showing 75% (3/4, 0.25-2.0 h) and 50% (2/4, 4.0 h) protection against minimal clonic seizure at 100 mg/kg without any toxicity. 3-(Pyridin-4-yl)-N-(4-chlorophenyl)-6,7-dimethoxy-3a, 4-dihydro-3H-indeno[1,2-c] pyrazole-2-carboxamide (4f) showed protection in maximal electroshock (MES) seizure and subcutaneous metrazol (scMET) seizure at 300 mg/kg.

  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 active with IC50 > 4.83 mu M and CC50 4.83 mu M. 3-(4-Fluorophenyl)-6,7-dimethoxy-3a, 4-dihydro-3H-indeno[1,2-c]pyrazole-2-carbothioamide (D41) was found to be the most active compound against bacterial strains with MIC of 4 mu g/ml, comparable to the standard drug ciprofloxacin while 3-(4-methoxyphenyl)-6,7-dimethoxy-3a, 4-dihydro-3H-indeno[1,2-c]pyrazole-2-carboxamide (D38) was found to be the most active compound against fungal strains with MIC 2-4 mu g/ml, however less active than standard fluconazole. Toxicities prediction by Osiris were well supported and experimentally verified with exception of some compounds. In anticonvulsant screening, 3-(4-fluorophenyl)-N-(4-chlorophenyl)-6,7-dimethoxy-3a,4-dihydro-3H-indeno[1,2-c]pyrazole-2-carboxamide (D09) showed maximum activity showing 100% (4/4, 0.25-0.5 h) and 75% (3/4, 1.0 h) protection against minimal clonic seizure test without any toxicity.

  In the present investigation, a series of 3a,4-dihydro-3H-indeno[1,2-c]pyrazole-2-carboxamide/carbothioamide analogues were synthesized and were evaluated for antitubercular activity by two fold serial dilution technique. All the newly synthesized compounds showed low to high inhibitory activities against Mycobacterium tuberculosis H(37)Rv and INH resistant M. tuberculosis. The compound 3-(4-fluorophenyl)-6,7-dimethoxy-3a, 4-dihydro-3H-indeno[1,2-c]pyrazole-2-carbothioamide (4o) was found to be the most promising compound active against M. tuberculosis H(37)Rv and isoniazid resistant M. tuberculosis with minimum inhibitory concentration 3.12 mu M and 6.25 mu M, respectively.
