The coordination behavior of 5-methylpyrazole-3-carboxylic acid (Hmpca) has been demonstrated by the solid state isolation and characterization of [Cu(mpca)2(H2O)]·3H2O (1) [Cu(mpca)2]·H2O (2) and [Co(mpca)2(H2O)2] (3). The new compounds are characterized by X-ray crystallography, thermogravimetric analysis and DFT study. The redox properties of the complexes are examined by cyclic voltammetric analysis. The antibacterial and antifungal activities of the compounds against eight bacteria (Escherichia coli, Enterococcus faecalis, Bacillus subtilis, Klebsiella pneumoniae, Proteus vulgaris, Staphylococcus aureus, Pseudomonas aeruginosa and Salmonella typhi) and two fungi (Aspergillus flavus and Candida albicans) are screened using modified agar well diffusion method. The metal complexes demonstrate better inhibition on all bacteria and fungi than the ligand. The high lipophilicity of the complexes accounts for good inhibitory action toward microbes. Among the reported complexes, 3 emerges as an excellent antifungal agent and a better antibiotic than standard fluconazole. The structure and activity relationship indicate that complexes having sufficient Jahn–Teller distortion with high logP values, cross the cell membrane of the microbes creating intercellular damage.

A number of pyrazole-oxadiazole conjugates were synthesized and evaluated for their ability to function as antiproliferative agents on various human cancer cell lines. These conjugates are comprised of pyrazole and oxadiazole scaffolds closely attached to each other without any spacer as two structural classes. The Type I class has a trimethoxy substituent and the type II class has a 3,4-(methylenedioxy) substituent on their A rings. Among these conjugates, 11a, 11d and 11f manifest potent cytotoxicity with IC50values ranging from 1.5 μM to 11.2 μM and inhibit tubulin polymerization with IC50values of 1.3 μM, 3.9 μM and 2.4 μM respectively. The cell cycle assay showed that treatment with these conjugates results in accumulation of cells in the G2/M phase and disrupts the microtubule network. Elucidation of zebrafish embryos revealed that the conjugates cause developmental defects. Molecular docking simulations determined the binding modes of these potent conjugates at the colchicine site of tubulin.
