3,5-Diarylazoles as novel and selective inhibitors of protein kinase D
摘要:
The synthesis and preliminary studies of the SAR of novel 3,5-diarylazole inhibitors of Protein Kinase D (PKD) are reported. Notably, optimized compounds in this class have been found to be active in cellular assays of phosphorylation-dependant HDAC5 nuclear export, orally bioavailable, and highly selective versus a panel of additional putative histone deacetylase (HDAC) kinases. Therefore these compounds could provide attractive tools for the further study of PKD / HDAC5 signaling. (C) 2011 Elsevier Ltd. All rights reserved.

The present invention provides novel organic compounds of formula (I) or (Ia): which may be inhibitors of a selective subset of kinases belonging to the AGC or calmodulin kinase family, such as for example PKD-1/2/3, inhibitors of histone deacetylase (HDAC) phosphorylation, or inhibitors of other kinases. The selectivity of which would depend on the structural variation thereof, and for treatment of a disorder or disease mediated by those selected AGC or calmodulin family kinases. These organic compounds can be used to treat various PKD associated states such as heart failure, colorectal cancer, regulation of cell growth, autoimmune disorders, or hyperproliferative skin disorders.
The present invention provides a protein kinase D (PKD) inhibitor for use in a method of treating or preventing picornavirus infection. Any PKD inhibitor may be use in the present invention, but the PKD inhibitor is typically selected from the group consisting of a small molecule, a small interfering RNA (siRNA), a short hairpin RNA (shRNA), a microRNA (miRNA), an antisense RNA, a ribozyme, a DNAzyme and a cDNA encoding an inactive mutant of PKD.
