Synthesis and Antitubercular Evaluation of Diverse Glycosylated Ureas from D-Glucose
(Hindawi Limited, 2024) Neetu Tripathi; Vinod K. Tiwari
N, N-disubstituted glycosylated ureas have been synthesized in good-To-excellent yields by 1,4-conjugate addition of amines to glycosylated olefinic esters followed by reaction of resulting glycosyl β-Amino esters with diisocyanates. The developed sugar-based molecules were well characterized by extensive standard spectroscopic analysis including NMR (1H, 13C, and DEPT), IR, MS, and elemental analysis and were screened for their biological activity against Mycobacterium tuberculosis (M. Tb.), where some of them displayed potent antitubercular activity. The molecules have been designed keeping in view the well-known inhibitors of the enzymes involved in the biosynthesis of mycobacterial cell wall polymers and may be further explored as lead molecules for the successful development of a potential antitubercular drug candidate.Dedicated to Dr. Rama P. Tripathi, Former Chief Scientist at CSIR-Central Drug Research Institute, Lucknow, India, for his extraordinary contribution to "Drug development against Tuberculosis". © 2024 Neetu Tripathi and Vinod K.
