The present invention provides compound of formula 1, or an isotopic form, a stereoisomer, a tautomer, a pharmaceutically acceptable salt, a solvate, a polymorph, a prodrug, S-oxide or N-oxide thereof. The invention also relates toprocesses for their preparation, to pharmaceutical compositions containing them and use of the compound of formula 1, in the treatment of diseases or disorders mediated by EZH2 (enhancer of zeste homolog 2), particularly cancer.
Here, we describe the selection and optimization of a chemical series active in both a full-length and a fragment-based Huntington's disease (HD) assay. Twenty-four thousand small molecules were screened in a phenotypic HD assay, identifying a series of compounds bearing a 3-hydroxy-3-trifluoromethylpyrazole moiety as able to revert the toxicity induced by full-length mutant Htt by up to 50%. A chemical exploration around the series led to the identification of compound 4f, which demonstrated to be active in a Htt171-82Qrat primary striatal neuron assay and a PC12-Exon-1 based assay. This compound was selected for testing in R6/2 mice, in which it was well-tolerated and showed a positive effect on body weight and a positive trend in preventing ventricular volume enlargment. These studies provide strong rationale for further testing the potential benefits of 3-hydroxy-3-trifluoromethylpyrazoles in treating HD.
