In present work we have designed and synthesized total twelve novel 3-(3-(1H-indol-3-yl)-3-phenylpropanoyl)-4-hydroxy-2H-chromen-2-one derivatives 13(a-l) using Ho3+doped CoFe2O4nanoparticles as catalyst and evaluated for their potential antileishmanial and antioxidant activities. The compounds 13a, 13d and 13h were found to possess significant antileishmanial activity (IC50value = 95.50, 95.00 and 99.00 μg/mL, respectively) when compared to the standard sodium stibogluconate (IC50= 490.00 μg/mL). The compounds 13a (IC50= 12.40 μg/mL), 13d (IC50= 13.49 μg/mL), 13g (IC50= 13.24 μg/mL) and 13l (IC50= 13.74 μg/mL) had shown good antioxidant activity when compared with standards butylated hydroxy toluene (IC50= 16.5 μg/mL) and ascorbic acid (IC50= 12.8 μg/mL). After performing molecular docking studies, it was found that compounds 13a and 13d had potential to inhibit pteridine reductase 1 enzyme. In silico ADME pharmacokinetic parameters had shown promising results and none of the synthesized compounds had violated Lipinski's rule of five. Thus, suggesting that compounds from the present series can serve as important gateway for the design and development of new antileishmanial as well as antioxidant agent.

Tuberculosis caused by Mycobacterium tuberculosis remains a leading cause of mortality worldwide into 21st century. In continuation with our anti-tuberculosis research programme, in this work, we have prepared molecularly diverse coumarins clubbed with benzothiazepines as well as its aza-analogues-benzodiazepines by molecular hybridization. The resulting compounds were screened for their M. tuberculosis activity against H37Rv strains using microplate alamar blue assay. Among the designed diversity, the compounds 5k, 5n and 5o were found significantly active in primary anti-tuberculosis assay at minimum inhibitory concentration 50 values of 5k and 5o in level-2 screening were observed as >10μg/mL and 3.63μg/mL, respectively. Design and synthesis of more focused library and its three-dimensional quantitative structure activity relationship analysis are underway. In the present work, various coumarins clubbed with benzo(thi)diazepines were evaluated for their M. tuberculosis activity against H37Rv strains using MABA assay. The IC50 values of two analogs (compounds 5k and 5o) in level-2 screening were observed as >10μg/mL and 3.63μg/mL respectively.
