ABSTRACT

Objective: To evaluate the antitubercular effi cacy and safety of New Chemical Entity (NCE): 8-[(4-Chloro phenyl) sulfonyl]-7-Hydroxy-4-Methyl-2H-chromen-2-One (CSHMC) in guinea pigs. Materials and Methods: This pilot study was carried out in guinea pigs. They were infected with M. tuberculosis H37Rv (1.5 × 104 cfu/ guinea pig) via intramuscular route. After 30 days, infections were confi rmed in 6 guinea pigs by histopathology of spleen, lung, and liver. After that CSHMC (5 and 20 mg/kg) was administered for 1 month and its effect was compared with vehicle, rifampicin (60 mg/kg) and isoniazid (30 mg/kg). Effi cacy of CSHMC was evaluated on the basis of histopathologic scoring of lesion in lung, spleen, liver, and safety on the basis of measuring hemogram, liver and renal function parameters. Results: Isoniazid, rifampicin, and CSHMC (20 mg/kg) signifi cantly reduce the median lesion score in lung, spleen, and liver as compared to disease control group. Reduction in median lesion score for lung and spleen were not statistically signifi cant for CSHMC 5 mg/kg. CSHMC (20 and 5 mg/kg) did not produce any changes in hemogram, liver and renal function parameters with respect to normal values. Conclusions: CSHMC had shown signifi cant antitubercular effi cacy comparable to isoniazid and rifampicin and did not show hematological, hepato- and nephrotoxicity.
