Synthesis of 7200 Small Molecules Based on a Substructural Analysis of the Histone Deacetylase Inhibitors Trichostatin and Trapoxin
摘要:
[GRAPHICS]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.
The synthesis of novel N-Boc- and N-Fmoc protected hemithioindigo-based ω-aminoacids is described. An approach to modulate the thermal stability of a hemithioindigo subunit is presented. Placing the amino-group in the stilbene part from the para- to meta-position leads to an increase of the half-life of the thermally labile E-form from 19 h to 47 h.

(EN) The present invention provides a novel system for identifying compounds having desirable chemical or biological activities. According to the invention, test compounds are introduced into liquid droplets and assayed therein. The system is particularly useful for identifying compounds that act e.g., as catalysts, or that have biological activities. In preferred embodiments of the invention, the compounds are assayed $i(in vivo).(FR) L'invention concerne un nouveau système permettant d'identifier des composés ayant des activités chimiques ou biologiques désirables. Selon l'invention, on introduit des composés à étudier dans des gouttelettes de liquide et on les crible. Le système est particulièrement utile pour identifier des composés qui agissent par exemple comme catalyseurs ou qui ont des activités biologiques. Dans les modes de réalisation préférés de l'invention, les composés sont criblés in vivo.
