PubMed Abstract:
A potent inhibitor of the JmjC histone lysine demethylase KDM2A (compound 35 , pIC ₅₀ 7.2) with excellent selectivity over representatives from other KDM subfamilies has been developed; the discovery that a triazolopyridine compound binds to the active site of JmjC KDMs was followed by optimisation of the triazole substituent for KDM2A inhibition and selectivity.
