Enzymes of shikimate pathway, dehydroquinase and shikimate kinase represent comparatively newer targets for antitubercular research. Molecular hybridization approach was implemented by integrating the essential features of inhibitors acting on these enzymes of shikimate pathway. Considering the flexibility of alicyclic ring of reported dehydroquinase (DHQ) inhibitors and triazole ring, key feature of the virtual hits of Mtb shikimate kinase, a series of structurally novel, substituted 4H-1,2,4-triazol-3-yl cycloalkanols were designed as antimycobacterial agents. Docking studies of the molecules was carried out on the enzyme DHQ. All the synthesized compounds exhibited promising activity (MIC 0.59-15.5 μg/ml) against H37Rv strains of Mycobacterium tuberculosis using resazurin microtiter assay. Five of the evaluated compounds exhibit MIC 50 values indicate compounds are non-toxic, with selectivity indices >28. These compounds could serve as leads for further optimization to obtain novel antimycobacterial agents.
