Histone deacetylase 6 (HDAC6) removes the acetyl group from lysine residues in a number of non-histone substrates and plays important roles in microtubule dynamics and chaperone activities. There is growing interest in identifying HDAC6-selective inhibitors as chem. biol. tools and ultimately as new therapeutic agents. Herein we report the design, synthesis, and phenotypic screening of a novel class of 3-aminopyrrolidinone-based hydroxamic acids as HDAC6 inhibitors. In particular, the α-methyl-substituted enantiomer I (3-S) showed significant in-cell tubulin acetylation (Tub-Ac) with an EC50 of 0.30 μM but limited impact on p21 levels at various concentrations In enzyme inhibition assays, I demonstrated high selectivity for HDAC6 with an IC50 of 0.017 μM and selectivity indexes of 10 against HDAC8 and over 4000 against HDAC1-3 isoforms. Moreover, I has suitable drug metabolism and pharmacokinetics properties compared with other hydroxamic acid-based HDAC inhibitors, warranting further biol. studies and development as a selective HDAC6 inhibitor. In the experiment, the researchers used many compounds, for example, Methyl 4-bromo-2-fluorobenzoate (cas: 179232-29-2COA of Formula: C8H6BrFO2).
Methyl 4-bromo-2-fluorobenzoate (cas: 179232-29-2) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. alpha-Bromoesters are employed in the Reformatsky reaction for the synthesis of beta-hydroxyesters. In the pharmaceutical industry organo bromine derivatives are used as sedatives, vasodilators, antiseptic agents, and anticancer agents.COA of Formula: C8H6BrFO2
