Discovery of a small molecule MDM2 inhibitor (AMG 232) for treating cancer

We recently reported the discovery of AMG 232 (1), a potent and selective piperidinone inhibitor of the MDM2-p53 protein-protein interaction. Compound 1 is currently being evaluated in human clinical trials for the treatment of cancer. This article provides an overview of its discovery from the de novo design of the piperidinone series to the structure-activity studies leading to the identification of 1. In addition, this article also describes the preclinical pharmacology and pharmacokinetics of 1, along with its drug metabolism and safety assessment.

Development of a Robust and Highly Selective Ru(II)-Catalyzed Dynamic Kinetic Resolution Used to Manufacture AMG 232

We describe herein the development of a scalable Noyori reductive dynamic kinetic resolution to manufacture DLAC, a ? -lactone precursor to the active pharmaceutical ingredient AMG 232. Central to this work was the identification of the ruthenabicyclic complex RuCl[(S)-daipena][(S)-xylBINAP] ((S)-RUCY-xylBINAP), which afforded the product with >98:2 enantiomeric ratio at a substrate to catalyst loading (S/C) of 2000:1. By transesterification to a more sterically hindered isopropyl ester prior to the hydrogenation, we were able to curb unexpected ester reduction. Optimization of base equivalents in the final alkylation step to form DLAC prevented product degradation. The optimized process was scaled to >200 kg, providing 147 kg of DLAC in 56percent overall yield with 99.9percent optical purity.

Discovery of AM-7209, a potent and selective 4-amidobenzoic acid inhibitor of the MDM2-p53 interaction

Structure-based rational design and extensive structure-activity relationship studies led to the discovery of AMG 232 (1), a potent piperidinone inhibitor of the MDM2-p53 association, which is currently being evaluated in human clinical trials for the treatment of cancer. Further modifications of 1, including replacing the carboxylic acid with a 4-amidobenzoic acid, afforded AM-7209 (25), featuring improved potency (KD from ITC competition was 38 pM, SJSA-1 EdU IC50 = 1.6 nM), remarkable pharmacokinetic properties, and in vivo antitumor activity in both the SJSA-1 osteosarcoma xenograft model (ED50 = 2.6 mg/kg QD) and the HCT-116 colorectal carcinoma xenograft model (ED50 = 10 mg/kg QD). In addition, 25 possesses distinct mechanisms of elimination compared to 1.

An expeditious synthesis of the MDM2-p53 inhibitor AM-8553

The development of the structurally complex MDM2/p53 inhibitor AM-8553 was impeded by the low yield of the initial synthesis. A second generation synthesis is described that features a Noyori dynamic kinetic resolution, a highly diastereoselective allylation, and a novel oxazoline-assisted piperidinone forming reaction to provide AM-8553 in 35.6% yield and 11 steps.
