Nutlin

Nutlins are cis-imidazoline analogs which inhibit the interaction between mdm2 and tumor suppressor p53, and which were discovered by screening a chemical library by Vassilev et al. Nutlin-1, nutlin-2, and nutlin-3 were all identified in the same screen;[1] however, Nutlin-3 is the compound most commonly used in anti-cancer studies.[2] Nutlin small molecules occupy p53 binding pocket of MDM2 and effectively disrupt the p53–MDM2 interaction that leads to activation of the p53 pathway in p53 wild-type cells.[3] Inhibiting the interaction between mdm2 and p53 stabilizes p53, and is thought to selectively induce a growth-inhibiting state called senescence in cancer cells. These compounds are therefore thought to work best on tumors that contain normal or "wild-type" p53. Nutlin-3 has been shown to affect the production of p53 within minutes.[4]

The more potent of the two enantiomers, (−)-nutlin-3, can be synthesized in a highly enantioselective fashion.[5] Several derivatives of nutlin, such as RG7112 and RG7388 (Idasanutlin) have been developed and progressed into human studies.[6]
