Design, synthesis and biological evaluation of novel N,4-diphenylthiazol-2-amine derivatives

Novel N,4-diphenylthiazol-2-amine derivatives were designed and synthesized employing Hantzsch method. The three-step reaction involved in the synthesis occurred at a faster rate with excellent yields in eco-friendly conditions. The synthesized derivatives were characterized by spectral techniques such as 1 H NMR, 13 C NMR, FT-IR and GCMS. Single-crystal X-ray diffraction studies also confirmed the formation of title compounds. These compounds were evaluated in vitro for their antimicrobial and anti-inflammatory activities. The results demonstrated that most of the tested compounds showed potent antifungal activity. Interestingly, these compounds also exhibited good anti-inflammatory and moderate antibacterial activity towards sensitive as well as resistant bacterial strains. In silico studies depicted their good binding affinity profile against S. aureus (PDB ID: 1AD4) and C. albicans (PDB ID: 1AI9).
