MedKoo CAT#: 200340

CAS#: 123018-47-3

Description: Atiprimod is an orally bioavailable small molecule belonging to the azaspirane class of cationic amphiphilic agents with anti-inflammatory, antineoplastic, and antiangiogenic properties. Atiprimod inhibits the phosphorylation of signal transducer and activator of transcription 3 (STAT3), blocking the signalling pathways of interleukin-6 and vascular endothelial growth factor (VEGF) and downregulating the anti-apoptotic proteins Bcl-2, Bcl-XL, and Mcl-1, thereby inhibiting cell proliferation, inducing cell cycle arrest, and inducing apoptosis.

Additional Information

Atiprimod (INN, code named SK&F106615; also known as azaspirane, although this more properly refers to the class of chemicals to which atiprimod belongs) is a substance being studied in the treatment of certain multiple myelomas and other advanced cancers. Atiprimod may block the growth of tumors and the growth of blood vessels from surrounding tissue to the tumor. Atiprimod is a type of signal transduction inhibitor. It was first developed by SmithKline Beecham (now part of GlaxoSmithKline) as a potential treatment for rheumatoid arthritis. January 7, 2008 Callisto Pharmaceuticals, Inc. announced that it has restructured its license agreement with Genzyme Corporation for Atiprimod. In August 2002, CallistoÂ’s wholly owned subsidiary, Synergy, acquired from AnorMED Inc. worldwide exclusive rights to develop, manufacture and commercialize Atiprimod. AnorMED was acquired by Genzyme in November 2006. The restructured agreement eliminates all milestone payments and reduces royalties owed to Genzyme to single digits. In return for the reduced future payments to Genzyme, Callisto is paying an upfront fee in 2008 Synergy Pharmaceuticals, Inc. (a wholly-owned subsidiary of Callisto) entered into a license agreement with AnorMED Inc. to license Atiprimod from AnorMED. Atiprimod is a macrophage-targeting oral cytokine inhibitor which is being developed by AnorMED as a potential treatment for rheumatoid arthritis and other autoimmune diseases. Phase I trials have been successfully completed and Phase II multicenter trials have been approved by the FDA. The compound was discovered in a joint research and development program with SmithKline and French (now SmithKline Beecham, SB) but following acceptance of the Phase II protocol by the FDA, SB decided not to proceed with further development of atiprimod as a result of an internal restructuring program. All rights to atiprimod and other azaspiranes developed in this program have reverted to AnorMED. The compound was originally disclosed in European patent, EP-00310321, entitled 'Preparation of N-aminoalkyl-2-azaspiro[4.5]decanes and analogs as immunosuppressants', while a cost-effective, efficacious pilot plant synthesis has also been described.
