摘要
Two classes of 1,4-disubstituted 1,2,3-triazoles were synthesized using one-pot reaction of alpha-tosyloxy ketones/alpha-halo ketones, sodium azide, and terminal alkynes in the presence of aq PEG (1: 1, v/v) using the click chemistry approach and evaluated for Src kinase inhibitory activity. Structure-activity relationship analysis demonstrated that insertion of C6H5- and 4-CH3C6H4- at position 4 for both classes and less bulkier aromatic group at position 1 in class 1 contribute critically to the modest Src inhibition activity (IC50 = 32-43 mu M) of 1,4-disubstituted 1,2,3-triazoles.
