SAHA

It is the first HDAC inhibitor approved by the US Food and Drug Administration (FDA) for the treatment of cutaneous T-cell lymphoma (CTCL) with significant skin involvement that is still progressing, resistant or relapsing after two systemic regimens. On October 6, 2006, the US Food and Drug Administration (FDA) have approved vorinostat capsules (vorinostat) for the treatment of skin cancer drugs. The drug is the first novel type of anti-cancer drugs of histone deacetylase inhibitor devel.

Vorinostat is a dicarboxylic acid diamide comprising suberic (octanedioic) acid coupled to aniline and hydroxylamine. A histone deacetylase inhibitor, it is marketed under the name Zolinza for the treatment of cutaneous T cell lymphoma (CTCL). It has a role as an EC 3.5.1.98 (histone deacetylase) inhibitor, an apoptosis inducer and an antineoplastic agent. It is a hydroxamic acid and a dicarboxylic acid diamide. It derives from a suberic acid, a hydroxylamine and an aniline.|Vorinostat (rINN) or suberoylanilide hydroxamic acid (SAHA), is a drug currently under investigation for the treatment of cutaneous T cell lymphoma (CTCL), a type of skin cancer, to be used when the disease persists, gets worse, or comes back during or after treatment with other medicines. It is the first in a new class of agents known as histone deacetylase inhibitors. A recent study suggested that vorinostat also possesses some activity against recurrent glioblastoma multiforme, resulting in a median overall survival of 5.7 months (compared to 4 - 4.4 months in earlier studies). Further brain tumor trials are planned using combinations of vorinostat with other drugs.|Vorinostat is a Histone Deacetylase Inhibitor. The mechanism of action of vorinostat is as a Histone Deacetylase Inhibitor.|Vorinostat is an oral histone deacetylase inhibitor and antineoplastic agent that is approved for use in refractory or relapsed cutaneous T cell lymphoma. Vorinostat is associated with modest rate of minor serum enzyme elevations during therapy, but has not been linked to cases of clinically apparent liver injury.|Vorinostat is a synthetic hydroxamic acid derivative with antineoplastic activity. Vorinostat, a second generation polar-planar compound, binds to the catalytic domain of the histone deacetylases (HDACs). This allows the hydroxamic moiety to chelate zinc ion located in the catalytic pockets of HDAC, thereby inhibiting deacetylation and leading to an accumulation of both hyperacetylated histones and transcription factors. Hyperacetylation of histone proteins results in the upregulation of the cyclin-dependant kinase p21, followed by G1 arrest. Hyperacetylation of non-histone proteins such as tumor suppressor p53, alpha tubulin, and heat-shock protein 90 produces additional anti-proliferative effects. This agent also induces apoptosis and sensitizes tumor cells to cell death processes. Vorinostat crosses the blood-brain barrier.|A hydroxamic acid and anilide derivative that acts as a HISTONE DEACETYLASE inhibitor. It is used in the treatment of CUTANEOUS T-CELL LYMPHOMA and SEZARY SYNDROME.
