The present invention relates to novel inhibitors of serine type peptidases in general and of serine type dipeptidyl peptidases in particular. The present invention further relates to the use of the dipeptidyl peptidase inhibitors for selective inhibition of dipeptidyl peptidases. The present invention also relates to pharmaceutical compositions comprising these novel dipeptidyl peptidase inhibitors. The present invention further relates to the use of the novel inhibitors in therapy, diagnosis and research.

An object of the present invention is to provide a novel therapeutic agent for a patient with type 2 diabetes, a cause of which is the abnormal synthesis of insulin attributed to the abnormal modification of tRNA
Lys
(UUU) in pancreatic β cells having Cdkal1 gene mutation. The present inventors have used (1) a screening system using
E. coli
in which correct translation into luciferase requires frameshift resulting from mistranslation during protein translation, (2) a screening system using the pancreatic islet of Langerhans isolated from a pancreatic β cell-specific Cdkal1-deficient mouse, and (3) a screening system using a pancreatic β cell-specific Cdkal1-deficient mouse, and found that a compound represented by any of the following formulas (I) to (III) can serve as a therapeutic agent for a patient with type 2 diabetes with Cdkal1 gene mutation resulting in the reduced ability to secrete insulin.

The invention relates to novel derivatives of short-chain fatty acids, in particular derivatives of butyric acid, useful for all the known clinical applications of the latter, which show physicochemical characteristics suitable for an easy oral administration, being devoid of the unpleasant organoleptic properties that characterize butyrate. The new compounds are amide derivatives which can be synthesized by reaction of the corresponding fatty acid halide with a naturally occurring amino acid, phenylalanine or a suitable derivative thereof, and which are in a poorly hygroscopic, easily weighable form, stable to acids and alkalis and able to release the acid at the small and large bowel level in a constant manner over time. They do not have disagreeable odors and are practically tasteless, thus allowing the manufacture of preparations for oral administration also suitable for the therapy of chronic diseases and in the pediatric field.

An amino group transfer strategy was developed to install free NH2 to the α-position of native carbonyls under mild conditions. The resulting primary α-aminated products are amenable to in situ peptide coupling or Pictet–Spengler cyclization in one-pot procedures. We anticipate this method to provide a general platform towards the synthesis of amines, ultimately opening exciting avenues in the synthesis
