Promising antitumor activity with MGCD0103, a novel isotype-selective histone deacetylase inhibitor

[摘要]：

Background: Histone deacetylases (HDACs), which target histones as well as non-histone proteins as substrates, have the potential to regulate aberrant gene expression and restore normal growth control in malignancies. Objective: This review provides an updated summary of preclinical and clinical experience with the oral isotype-selective HDAC inhibitor MGCD0103 in cancer. Methods: Data presented in abstract form from international conferences or journal articles found within a PubMed search of article up to May 2008 are described in this review. Results/conclusions: MGCD0103 appears tolerable and exhibits favorable pharmacokinetic and pharmacodynamic profiles with evidence of target inhibition in surrogate tissues. Clinical and pharmacodynamic data support a three-times-weekly administration at a 90-mg fixed dose. MGCD0103 displays promising antitumor activity in hematological and lymphoproliferative diseases.
