摘要:
A synthetic strategy to access small libraries of triazolylmethoxy chalcones 4{1-20}, triazolylmethoxy flavanones 5{1-10} and triazolylmethoxy aminopyrimidines 6{1-17} from a common substrate 4-propargyloxy-2-hydroxy acetophenone using a set of different reactions has been developed. The chalcones and flavanones were screened against mycobacterial FAS-II pathway using a recombinant mycobacterial strain, against which the most potent compound showed similar to 88% inhibition in bacterial growth and substantially induction of reporter gene activity at 100 mu M concentration. The triazolylmethoxy aminopyrimdines were screened against PknG of Mycobaceterium tuberculosis displaying moderate to good activity (23-53% inhibition at 100 mu M), comparable to the action of a standard inhibitor.
