Article Abstract
A series of (2S)-cyanopyrrolidines with glutamic acid derivatives at the P2 site have been prepared and evaluated as inhibitors of dipeptidyl peptidase IV (DPP-IV). The structure-activity relationships (SAR) led to the discovery of potent 3-substituted glutamic acid analogues, providing enhanced chemical stability and excellent selectivity over the closely related enzymes, DPP8, DPP-II and FAP. Compound 13f exhibited the ability to both significantly decrease the glucose excursion and inhibit plasma DPP-IV activity.

Division of Cardiology, Department of Internal Medicine, New Taipei Municipal TuCheng Hospital, New Taipei, Taiwan.
Importance: The cardiovascular benefits of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) may vary by body mass index (BMI), but evidence on BMI-specific outcomes remains limited.
Objective: To investigate the associations of GLP-1 RA use with cardiovascular and kidney outcomes across BMI categories in patients with type 2 diabetes.
Design, Setting, And Participants: This retrospective cohort study used the Chang Gung Research Database, a clinical dataset covering multiple hospitals in Taiwan.
Effect of the DPP4 Inhibitor Sitagliptin on Ferroptosis in Epilepsy.

Background: Epilepsy, a significant neurological condition marked by the occurrence of repeated seizures, continues to pose a substantial health challenge. Previous studies have indicated that Dipeptidyl Peptidase-4 (DPP4) inhibitors may possess antiepileptic properties. Ferroptosis, a newly discovered type of programmed cell death, has recently surfaced as a promising therapeutic target in the management of epilepsy.

Dipeptidyl peptidase 1 (DPP1) inhibitors constitute a major advance in respiratory disease therapeutics. Through selective blockade of neutrophil serine protease (NSP) activation, these agents establish novel treatment paradigms for inflammatory respiratory conditions characterized by neutrophil-driven pathology. This comprehensive review examines the development status, clinical efficacy, and safety profile of DPP1 inhibitors in neutrophil-driven diseases, particularly non-cystic fibrosis bronchiectasis (NCFBE) and chronic obstructive pulmonary disease (COPD).

Dipeptidyl-peptidase 4 inhibitors, DPP-4i, are an established antiglycaemic medication for Type 2 Diabetes. There has been a growing interest in DPP-4i's potential to improve wound healing and reduce fibrosis. The purpose of this study is to survey the current literature for applications of DPP-4i in wound healing and scars, and explore their potential outside of glycaemic control.

Tree-based scan statistics (TBSS) are data mining methods that screen thousands of hierarchically related health outcomes to detect unsuspected adverse drug effects. TBSS traditionally analyze claims data with outcomes defined via diagnosis codes. TBSS have not been previously applied to rich clinical information in Electronic Health Records (EHR).
