The long term side effects of any newly introduced drug is a subject of intense research, and often raging controversies. One such example is the dipeptidyl peptidase-IV (DPP4) inhibitor used for treating type 2 diabetes, which is inconclusively implicated in increased susceptibility to acute pancreatitis. Previously, based on a computational analysis of the spatial and electrostatic properties...

The contents of [Met5]-enkephalin-Arg6-Gly7-Leu8 (met-enk-RGL) and its seven hydrolysis products-Y, YG, YGG, YGGF, YGGFM, YGGFMR, and YGGFMRG-were estimated after incubating met-enk-RGL with a membrane fraction from either guinea pig ileum or striatum for various times at 37 degrees C. After 15 min of incubation, met-enk-RGL was completely hydrolyzed in both the ileal and the striatal membrane ...

An improved multistep synthesis of tricyclic α-cyanopyrrolidine from camphor is presented. The synthesis was carried out by maintaining the cyano group in the form of an amide and its regeneration after the completion of the necessary chemical transformation of a particular functional group. The tricyclic α-cyanopyrrolidine prepared was used to synthesize two novel compounds of DPP4 (Dipeptidyl...

AIMS/INTRODUCTION Recently, dipeptidyl peptidase-4 (DPP-4) inhibitors have become available in Japan. It has not yet been clarified what clinical parameters could discriminate DPP-4 inhibitor-effective patients from DPP-4 inhibitor-ineffective patients. MATERIALS AND METHODS We reviewed 33 consecutive patients with type 2 diabetes admitted to Osaka University Hospital for glycemic control. Al...

The presence of DPPII (dipeptidyl peptidase II; E.C. 3.4.14.2) has been demonstrated in various mammalian tissues. However, a profound molecular and catalytic characterization, including substrate selectivity, kinetics and pH-dependence, has not been conducted. In the present study, DPPII was purified from human seminal plasma to apparent homogeneity with a high yield (40%) purification scheme,...

Hydrolysis of the neuropeptide N-acetyl-L-aspartyl-L-glutamate (NAAG) by N-acetylated alpha-linked acidic dipeptidase (NAALADase) to release glutamate may be important in a number of neurodegenerative disorders in which excitotoxic mechanisms are implicated. The gene coding for human prostate-specific membrane antigen, a marker of prostatic carcinomas, and its rat homologue glutamate carboxypep...
