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.
For more than a third of children living with epilepsy, the currently approved medications do not stop their seizures. This statistic has not changed for the past five decades, despite the development of many new anti-seizure drugs.
Researchers from the John Theurer Cancer Center at Hackensack University Medical Center, one of the nation's top 50 best hospitals for cancer, presented results from 31 major studies of blood-related cancers - leukemia, lymphoma and multiple myeloma -- during the American Society of Hematology (ASH) Annual Meeting, December 10-13, 2011 in San Diego.
Arno Therapeutics, Inc. has announced that the U.S. Food and Drug Administration ("FDA") accepted the Company's Investigational New Drug ("IND") application for the use of AR-42.
Results from two Phase 1 studies of ZOLINZA (vorinostat), Merck's oral histone deacetylase (HDAC) inhibitor, administered in combination with bortezomib, showed early anti-tumor activity in patients with relapsed and/or refractory multiple myeloma, including those previously treated with and no longer responding to bortezomib.
Researchers at the University of Adelaide have developed a novel approach to treating advanced prostate cancer that could be more effective with fewer side effects.
A new University of Michigan study in mice suggests that a drug recently approved to fight cancer tumors is also able to reduce the effects of graft-versus-host disease, a common and sometimes fatal complication for people who have had bone marrow transplants.
Results from two investigational Phase I trials of ZOLINZA (vorinostat) in combination with bortezomib provide preliminary anti-tumor activity in patients with relapsed and/or refractory multiple myeloma.
Researchers have discovered new small molecules that may prevent prostate cancer cells from turning off normal genes in a process that transforms normal cells into cancer cells. This significant discovery in the field of epigenetics has immediate implications in the development of new diagnostic tests and cancer medications.
North Central Cancer Treatment Group (NCCTG) researchers, based at Mayo Clinic in Rochester, Minn., report that a novel application of the drug vorinostat shows activity in patients with recurrent glioblastoma multiforme.
Leading figures in the global fight against lung cancer are meeting in the city of Geneva, Switzerland this week to discuss the latest tools for preventing and treating chest malignancies, which kill more than 1.3 million people each year.
The U.S. Food and Drug Administration (FDA) has approved Zolinza (vorinostat) capsules 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.
