A new series of heterocyclic compounds containing both N-methyl thiotetrazole (NMTT) and piperidine nuclei together, namely ethyl 5-(1-methyl-1H-tetrazol-5-ylthio)-4-oxo-2,6-substituted diphenylpiperidine-3-caboxylate derivatives, were synthesized by cyclocondensation of ethyl 4-(1-methyl-1H-tetrazol-5-ylthio)-3-oxobutanoate with ammonium acetate and substituted aromatic aldehydes. The synthesized N-methylthio tetrazole substituted piperidine-4-one derivatives were evaluated for their antimicrobial activity using disc diffusion method. The structures of the synthesized compounds were characterized by Infrared Radiation (IR), Proton Nuclear Magnetic Resonance (¹H-NMR), Carbon-13 (C13) Nuclear Magnetic Resonance (¹³C-NMR), 2D-NMR and mass spectral data. The antimicrobial activity reveals that several compounds exhibit good antibacterial activity when compared with the reference drug. Molecular docking studies were performed against malarial activities.
