  名称：

  Design, synthesis, and antitubercular evaluation of novel series of 3-benzofuran-5-aryl-1-pyrazolyl-pyridylmethanone and 3-benzofuran-5-aryl-1-pyrazolylcarbonyl-4-oxo-naphthyridin analogs

  摘要：

  Twenty-eight newer 3-benzofuran-5-aryl-1-pyrazolyl-pyridylmethanone and 3-benzofuran-5-aryl-1-pyrazolylcarbonyl-4-oxo-naphthyridin analogs were synthesized by microwave irradiation method and evaluated for in-vitro and in-vivo antitubercular activity against multidrug-resistant M. tuberculosis stains. Structure activity relationship study was carried out and found NO2 (o) substituted 3-benzo-furan-5-aryl-1-pyrazolylcarbonyl-4-oxo-naphthyridin was most potent antitubercular agent against M. tuberculosis, even better than standard drug isoniazid and comparable with rifampin. Other synthesized compounds 7j, 7f, 7a, 7e and 5d, 5f were found moderate to good activity in in-vitro model at lower IC50 values 85 mu M, 154 mu M, 157 mu M, 164 mu M, 170 mu M and 190 mu ML respectively. In in-vivo animal model compound 7j was drastically reduced the bacterial load in lung and spleen tissues at the dose of 25 mg/kg body weight. (C) 2010 Elsevier Masson SAS. All rights reserved.
