Synthesis of 7200 small molecules based on a substructural analysis of the histone deacetylase inhibitors trichostatin and trapoxin

Org Lett. 2001 Dec 27;3(26):4239-42. doi: 10.1021/ol016915f.


Seventy-two hundred potential inhibitors of the histone deacetylase (HDAC) enzyme family, based on a 1,3-dioxane diversity structure, were synthesized on polystyrene macrobeads. The compounds were arrayed for biological assays in a "one bead-one stock solution" format. Metal-chelating functional groups were used to direct the 1,3-dioxanes to HDAC enzymes, which are zinc hydrolases. Representative structures from this library were tested for inhibitory activity and the 1,3-dioxane structure was shown to be compatible with HDAC inhibition. [structure: see text]
