Abstract

Here we describe a rapid and divergent synthetic route toward structurally novel αHTs functionalized with either one or two thioether or sulfonyl appendages. Evaluation of this library against hepatitis B and herpes simplex virus, as well as the pathogenic fungus Cryptococcus neoformans, and a human hepatoblastoma (HepDES19) revealed complementary biological profiles and new lead compounds with sub-micromolar activity against each pathogen.
