Abstract
The six-membered ring heterocycle 1,3,5-triazine and its derivatives have attracted considerable attention as they have proven to be excellent bioactive herbicides, cancer agents, etc. A series of 1,3,5-triazine derivatives (3a-o) were synthesized by a single step reaction and characterized by 1H NMR, 13C NMR, and mass spectrometry analysis. Antimicrobial screening of title compounds (3a-o) was examined against five bacterial and two fungal strains. In vitro study revealed that the freshly synthesized 6-(thiazol-4-yl)-1,3,5-triazine-2,4-diamine (3o) showed good antibacterial growth inhibition against E. coli, K. pneumoniae, and A. baumannii bacterial strains, and even the fungi C. neoformans. Molecular docking studies were performed on the X-ray crystal structure of E. coli 24 kDa domain in complex with clorobiocin (PDB code: 1KZN; resolution 2.30 Å) using Surflex-Dock program of Sybyl-X software. The results obtained are very encouraging.
