Details of structure-activity relationships (SAR) for P2 moiety of a P1 2-cyanopyrrolidine dipeptidyl peptidase IV (DPP-IV) inhibitor 4a including stereochemistry are presented. Based on this information, a series of P1 (N-alkyl)aminoacetonitrile analogs 9-20 possessing optimal P2 structure were synthesized and evaluated as inhibitors of DPP-IV. Among them, a representative compound 11, N-(cyanomethyl)-N-ethyl-L-prolinamide, was further evaluated to determine its effect on the plasma glucose level. Also 4a, 10, and 11 were evaluated for their isozyme selectivity to predict their safety problems.

Purpose: Imeglimin is a novel oral antidiabetic agent that improves glucose tolerance. This study aimed to investigate the efficacy of combining imeglimin with dipeptidyl peptidase-4 inhibitor (DPP-4i), the most frequently prescribed first-line treatment for patients with type 2 diabetes (T2D) in Japan, to improve glycemic control.
Patients And Methods: Eleven patients with T2D treated with DPP-4i alone (6.

Aims: Insulin therapy is a cornerstone in type 2 diabetes mellitus (T2DM) management, but its use is associated with several barriers, including hypoglycaemia, fear of injections and high costs. We compared the risk of insulin initiation and other treatment intensification between patients with T2DM newly treated with a sodium-glucose cotransporter-2 inhibitor (SGLT2i) versus those newly treated with a dipeptidyl peptidase-4 inhibitor (DPP4i).
Materials And Methods: This Japanese retrospective cohort study was conducted between 1 January 2015 and 31 March 2023 using the JMDC Claims Database.

Cadmium (Cd) is a widely available metal that has been found to have a role in causing nonalcoholic fatty liver disease (NAFLD). However, the detailed toxicological targets and mechanisms by which Cd causes NAFLD are unknown. Therefore, the present work aims to reveal the main targets of action, cellular processes, and molecular pathways by which cadmium causes NAFLD.

Introduction: The aim of this study is to use observational methods to evaluate reliability of evidence generated by a study of the effect of glucagon-like peptide 1 receptor agonists (GLP-1RA) on chronic lower respiratory disease (CLRD) outcomes among Type-2 diabetes mellitus (T2DM) patients.
Research Design And Methods: We independently reproduced a study comparing effects of GLP-1RA versus dipeptidyl peptidase-4 inhibitors (DPP4-i) on CLRD outcomes among patients with T2DM and prior CLRD. We reproduced inputs and outputs using the original study data (national administrative claims) and evaluated the robustness of results in comparison to alternate design/analysis decisions.

Contrast-associated acute kidney injury (CA-AKI) remains a serious complication after percutaneous coronary revascularization (PCI), with limited effective preventive strategies especially for diabetic patients. This study aimed to assess the effects of novel antidiabetic agents (NAD), i.e.
