What is belinostat?

Belinostat is a prescription medicine that is used to treat T-cell lymphoma.

Description

Beleodaq is a histone deacetylase inhibitor with a sulfonamide-hydroxamide structure. The chemical name of belinostat is (2E)- N-hydroxy-3-[3-(phenylsulfamoyl)phenyl]prop-2-enamide. The structural formula is as follows:

Structure

The molecular formula is C 151424S and the molecular weight is 318.35 g/mol.

Belinostat is a white to off-white powder. It is slightly soluble in distilled water (0.14 mg/mL) and polyethylene glycol 400 (about 1.5 mg/mL), and is freely soluble in ethanol (> 200 mg/mL). The pKa values are 7.87 and 8.71 by potentiometry and 7.86 and 8.59 by UV.

Beleodaq (belinostat) for injection is supplied as a sterile lyophilized yellow powder containing 500 mg belinostat as the active ingredient. Each vial also contains 1000 mg L-Arginine, USP as an inactive ingredient. The drug product is supplied in a single-dose 30 mL clear glass vial with a coated stopper and aluminum crimp seal with “flip-off” cap. Beleodaq is intended for intravenous administration after reconstitution with 9 mL Sterile Water for injection, and the reconstituted solution is further diluted with 250 mL of sterile 0.9% Sodium Chloride injection prior to infusion

Mechanism of Action

Beleodaq is a histone deacetylase (HDAC) inhibitor. HDACs catalyze the removal of acetyl groups from the lysine residues of histones and some non-histone proteins. In vitro, belinostat caused the accumulation of acetylated histones and other proteins, inducing cell cycle arrest and/or apoptosis of some transformed cells. Belinostat shows preferential cytotoxicity towards tumor cells compared to normal cells. Belinostat inhibited the enzymatic activity of histone deacetylases at nanomolar concentrations (<250 nM).
