Description: Ridaforolimus, also known as AP23573, is an investigational small-molecule inhibitor of mTOR, a protein that acts as a central regulator of protein synthesis, cell proliferation, cell cycle progression and cell survival. mTOR integrates signals from proteins, such as PI3K, AKT and PTEN known to be important to malignancy. Blocking mTOR creates a starvation-like effect in cancer cells by interfering with cell growth, division, metabolism, and angiogenesis. It has had promising results in a clinical trial for advanced soft tissue and bone sarcoma.

ridaforolimus is a small molecule and non-prodrug analogue of the lipophilic macrolide antibiotic rapamycin with potential antitumor activity. Ridaforolimus binds to and inhibits the mammalian target of rapamycin (mTOR), which may result in cell cycle arrest and,consequently, the inhibition of tumor cell growth and proliferation. Upregulated in some tumors, mTOR is a serine/threonine kinase involved in regulating cellular proliferation, motility, and survival that is located downstream of the PI3K/Akt signaling pathway. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus).
Ridaforolimus (also known as AP23573 and MK-8669; formerly known as Deforolimus) is an immunosuppressant currently undergoing research for the treatment of certain cancers. It is a small-molecule inhibitor of the mammalian target of rapamycin (mTOR). Blocking mTOR creates a starvation-like effect in cancer cells by interfering with cell growth, division, metabolism, and angiogenesis. Ridaforolimus is being co-developed by Merck and ARIAD Pharmaceuticals. As of 2008, a phase III clinical trial of ridaforolimus in metastatic soft-tissue and bone sarcomas responsive to chemotherapy, SUCCEED (Sarcoma Multi-Center Clinical Evaluation of the Efficacy of Deforolimus), is recruiting patients. On May 5, 2010, Ariad Pharmaceuticals and Merck & Company announced a clinical development and marketing agreement. With this agreement, Ariad will receive an upfront payment of $50 million with an additional $19 million reimbursement for R&D expenses incurred to date in the program. Future payments are triggered upon acceptance of the NDA by the FDA with another payment when the drug receives marketing approval. There are similar milestones for acceptance and approval in both Europe and Japan. Other milestone payments are tied to revenue goals for the drug. the information was directly from: http://en.wikipedia.org/wiki/Ridaforolimus .
