Abstract

Abstract: Combining natural product fragments to design new scaffolds with unprecedented bioactivity is a powerful strategy for the discovery of tool compounds and potential therapeutics. However, the choice of fragments to couple and the biological screens to employ remain open questions in the field. By choosing a primary fragment containing the A/B ring system of estradiol and fusing it to nine different secondary fragments, we were able to identify compounds that modulated four different phenotypes: inhibition of autophagy and osteoblast differentiation, as well as potassium channel and tubulin modulation. The latter two were uncovered by using unbiased morphological profiling with a cell‐painting assay. The number of hits and variety in bioactivity discovered validates the use of recombining natural product fragments coupled to phenotypic screening for the rapid identification of biologically diverse compounds. Abstract : Synthesis and profiling of a collection of compounds containing the A/B ring system of estradiol fused to nine secondary fragments uncovered five scaffolds with diverse phenotypes, including osteoblast differentiation and autophagy inhibition as well as modulators of tubulin polymerization and potassium channels.
