Abstract

The results of a high-throughput screening assay using the DENV-2 replicon showed that the 2, 4-diaminoquinazoline derivative 4a has a high dengue virus inhibitory activity (EC50= 0.15 μM). A series of 2, 4-diaminoquinazoline derivatives based on 4a as a lead compound were synthesized and subjected to structure–antidengue activity relationship studies. Among the series of 2, 4-diaminoquinazoline derivative probed, 4o was observed to ...
