Anti-mitotic Activity of the Benzothiazole-pyrazole Hybrid Derivatives / M. Bhat, S.L. Belagali, N.K.H. Kumar, S. Jagannath
Background: Nitrogen-containing heterocyclics are abundant in natural products and also in synthetic drug molecules because of a variety of applications and superior pharmacological profile action. Pyrazoles are the integral architects of many of the heterocyclic compounds with superior biological activity. Methods: Two series of the pyrazole conjugated Benzothiazole derivatives were synthesized. The pyrazoles were synthesized by the Vilsmeier-Haack reaction and then conjugated with benzothiazole hydrazine and hydrazide by imine bond formation. The synthesized compounds were screened for anti-mitotic activity using Allium assay. Results: Here, the anti-mitotic activity, the percentage of cell division and the percentage of inhibition compared to the control were calculated. Compound 4b (-OMe), 4c (-OH), 5b (-OMe), 5c (- OH) and 5d (-CH3) had electron donating groups which showed excellent activity, was followed by 4f and 5f where they contain p-Bromo substitution, showing moderate activity. Conclusion: In the two series, benzothiazole linked to pyrazole through the hydrazide bridging (5a-5i) had superior to hydrazine bridging (4a-4i). The observed chromosomal aberrations are because of the structural morphology and binding sites of the molecule with the chromosome.
