3D-QSAR of histone deacetylase inhibitors as anticancer agents by genetic function approximation.

Histone deacetylases (HDACs) play a critical role in gene transcription and are implicated in cancer therapy and other diseases. Inhibitors of HDACs induce cell differentiation and suppress cell proliferation in the tumor cells. Although many such inhibitors have been designed and synthesized, but selective inhibitors for HDAC isoforms are lacking.

3D-QSAR of histone deacetylase inhibitors: hydroxamate analogues.

The histone deacetylase enzyme has increasingly become an attractive target for developing novel anticancer drugs. Hydroxamates are a new class of anticancer agents reported to act by selective inhibition of the histone deacetylase (HDAC) enzyme. Comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA) were employed to study three-dimensional quantitative structure-activity relationships (3D-QSARs).
