Synthesis and evaluation of novel orally active p53–MDM2 interaction inhibitors
摘要:
We have discovered and reported potent p53-MDM2 interaction inhibitors possessing dihydroimidazothiazole scaffold. Our lead showed strong activity in vitro, but did not exhibit antitumor efficacy in vivo for the low metabolic stability. In order to obtain orally active compounds, we executed further optimization of our lead by the improvement of physicochemical properties. Thus we furnished optimal compounds by introducing an alkyl group onto the pyrrolidine at the C-2 substituent to prevent the metabolism; and modifying the terminal substituent of the proline motif improved solubility. These optimal compounds exhibited good PK profiles and significant antitumor efficacy with oral administration on a xenograft model using MV4-11 cells having wild type p53. (C) 2013 Elsevier Ltd.

Masked Oxo Sulfinimines (N-Sulfinyl Imines) in the Asymmetric Synthesis of Proline and Pipecolic Acid Derivatives
摘要:
[GRAPHICS]On addition of Et2AlCN/i-PrOH, masked oxo sulfinimines give alpha -amino nitriles that afford oxo alpha -amino acids on hydrolysis. These amino acids cyclize and are reduced to cis proline and cis pipecolic acids derivatives in high ee and good yield. This new procedure avoids many of the limitations related to the preparation of oxo amino acids from proteinogenic amino acids.

The prolineanalogue (2S,3aS,7aS)-octahydroindole-2-carboxylic acid (Oic) has been previously applied as a prolinesubstitute in pharmocologically active peptides and as a structural component of the antihypertensive drug Perindopril. Herein, we describe the formation of an oligoproline structure by an Oic oligomer. A series of Oic oligomers were investigated to show the structural and energetic contribution
