The invention relates to a synthesis method of chiral aminopiperidine and derivatives thereof. 3 . The invention is carried out by R (or S) – piperidine -3 – ethyl ester – L (or D) – L (or D)-tartrate after benzyl protection followed by azide and Curtitius rearrangement to R or S -benzyl -3 -aminopiperidine. R or S – benzyl -3 – aminopiperidine undergoes debenzylation to give R or S -amino piperidine, R or S – benzyl -3 – aminopiperidine through 3 -t-butoxycarbonyl protection, for example. Of R or S – (3 – t-butoxycarbonyl amino) piperidine, R or S – (3 – t-butoxycarbonyl amino) piperidine under acidic conditions can give R or S – 3-aminopiperidine, corresponding salts. The synthesis method provides a low-cost, easily-industrialized chiral 3 -aminopiperidine with high optical purity and a method. (by machine translation)

Replacement of one of the morpholine groups of the phosphatidylinositol 3-kinase (PI3K) inhibitor ZSTK474 (1) with sulfonamide containing substituents produced a new class of active and potent PI3Kalpha inhibitors. Solubility issues prevented all but the 6-amino derivative 17 from being evaluated in vivo, but the clear activity of this compound demonstrated that this class of PI3K inhibitor shows great promise.

Molecular modeling of unbound tricyclic guanine scaffolds indicated that they can serve as effective bioisosteric replacements of xanthines. This notion was further confirmed by a combination of X-ray crystallography and SAR studies, indicating that tricyclic guanine DPP4 inhibitors mimic the binding mode of xanthine inhibitors, exemplified by linagliptin. Realization of the bioisosteric relationship between these scaffolds potentially will lead to a wider application of cyclic guanines as xanthine replacements in drug discovery programs for a variety of biological targets. Newly designed DPP4 inhibitors achieved sub-nanomolar potency range and demonstrated oral activity in vivo in mouse glucose tolerance test.
