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. or A drug used to treat urothelial cancer (a type of bladder cancer) that has advanced or spread to other parts of the body. It is used in patients whose disease got worse during or after treatment with anticancer drugs that included platinum. It is also being studied in the treatment of other types of cancer. Atezolizumab binds to a protein called PD-L1, which is found on some cancer cells. Atezolizumab may block this protein and help the immune system kill cancer cells. It is a type of monoclonal antibody and a type of immune checkpoint inhibitor. Also called Tecentriq.
