Vorinostat (rINN), also known as suberoylanilide hydroxamic acid, is a member of a larger class of compounds that inhibit histone deacetylases (HDAC). Histone deacetylase inhibitors (HDI) have a broad spectrum of epigenetic activities.
Histone deacetylase inhibitors are chemical compounds that inhibit histone deacetylases. Since deacetylation of histones produces transcriptionally silenced heterochromatin, HDIs can render chromatin more transcriptionally active and induce epigenomic changes.
TopoTarget was a Copenhagen-based biotechnology company focused on the discovery and development of drugs and therapies to treat cancer. In 2014, it merged with BioAlliance Pharma and is now part of Onxeo.
Panobinostat, sold under the brand name Farydak, is a medication used for the treatment of multiple myeloma. It is a hydroxamic acid and acts as a non-selective histone deacetylase inhibitor.
Belinostat is a histone deacetylase inhibitor drug developed by TopoTarget for the treatment of hematological malignancies and solid tumors.
Lenvatinib, sold under the brand name Lenvima among others, is an anti-cancer medication for the treatment of certain kinds of thyroid cancer and for other cancers as well. It was developed by Eisai Co. and acts as a multiple kinase inhibitor against the VEGFR1, VEGFR2 and VEGFR3 kinases.
Romidepsin, sold under the brand name Istodax, is an anticancer agent used in cutaneous T-cell lymphoma (CTCL) and other peripheral T-cell lymphomas (PTCLs). Romidepsin is a natural product obtained from the bacterium Chromobacterium violaceum, and works by blocking enzymes known as histone deacetylases, thus inducing apoptosis. It is sometimes referred to as depsipeptide, after the class of molecules to which it belongs. Romidepsin is branded and owned by Gloucester Pharmaceuticals, a part of Celgene.
Mocetinostat (MGCD0103) is a benzamide histone deacetylase inhibitor undergoing clinical trials for treatment of various cancers including follicular lymphoma, Hodgkin's lymphoma and acute myelogenous leukemia.
Entinostat, also known as SNDX-275 and MS-275, is a benzamide histone deacetylase inhibitor undergoing clinical trials for treatment of various cancers.
Brentuximab vedotin, sold under the brand name Adcetris, is an antibody-drug conjugate medication used to treat relapsed or refractory Hodgkin lymphoma (HL) and systemic anaplastic large cell lymphoma (ALCL), a type of T cell non-Hodgkin lymphoma. It selectively targets tumor cells expressing the CD30 antigen, a defining marker of Hodgkin lymphoma and ALCL. The drug is being jointly marketed by Millennium Pharmaceuticals outside the US and by Seagen in the US.
Phosphoinositide 3-kinase inhibitors are a class of medical drugs that are mainly used to treat advanced cancers. They function by inhibiting one or more of the phosphoinositide 3-kinase (PI3K) enzymes, which are part of the PI3K/AKT/mTOR pathway. This signal pathway regulates cellular functions such as growth and survival. It is strictly regulated in healthy cells, but is always active in many cancer cells, allowing the cancer cells to better survive and multiply. PI3K inhibitors block the PI3K/AKT/mTOR pathway and thus slow down cancer growth. They are examples of a targeted therapy. While PI3K inhibitors are an effective treatment, they can have very severe side effects and are therefore only used if other treatments have failed or are not suitable.
Crizotinib, sold under the brand name Xalkori among others, is an anti-cancer medication used for the treatment of non-small cell lung carcinoma (NSCLC). Crizotinib inhibits the c-Met/Hepatocyte growth factor receptor (HGFR) tyrosine kinase, which is involved in the oncogenesis of a number of other histological forms of malignant neoplasms. It also acts as an ALK and ROS1 inhibitor.
Brivanib alaninate (INN/USAN) also known as BMS-582664 is an investigational, anti-tumorigenic drug for oral administration. The drug is being developed by Bristol-Myers Squibb for the treatment of hepatocellular carcinoma or HCC, the most common type of liver cancer. Brivanib is no longer in active development.
Abexinostat is an experimental drug candidate for cancer treatment. It was developed by Pharmacyclics and licensed to Xynomic. As of 2013, it was in Phase II clinical trials for B-cell lymphoma. Pre-clinical study suggests the potential for treatment of different types of cancer as well.
Quisinostat is an experimental drug candidate for the treatment of cancer. It is a "second generation" histone deacetylase inhibitor with antineoplastic activity. It is highly potent against class I and II HDACs.
Pembrolizumab, sold under the brand name Keytruda, is a humanized antibody used in cancer immunotherapy that treats melanoma, lung cancer, head and neck cancer, Hodgkin lymphoma, stomach cancer, cervical cancer, and certain types of breast cancer. It is administered by slow intravenous injection.
Pracinostat (SB939) is an orally bioavailable, small-molecule histone deacetylase (HDAC) inhibitor based on hydroxamic acid with potential anti-tumor activity characterized by favorable physicochemical, pharmaceutical, and pharmacokinetic properties.
Copanlisib, sold under the brand name Aliqopa, is a medication used for the treatment of adults experiencing relapsed follicular lymphoma who have received at least two prior systemic therapies.
Tucidinostat is a histone deacetylase inhibitor (HDI) developed in China. It was also known as HBI-8000. It is a benzamide HDI and inhibits Class I HDAC1, HDAC2, HDAC3, as well as Class IIb HDAC10.
Zabadinostat is an experimental epigenetic drug being investigated as a potential treatment for advanced or metastatic cancers. It is an orally available Class I selective histone deacetylase (HDAC) inhibitor, with half maximal inhibitory concentrations (IC50) of 62 nM, 570 nM and 550 nM, against HDAC1, HDAC2 and HDAC3, respectively. It shows no activity against HDAC class II.
