Modelling the effects of human SUR1 R1420H variation on insulin secretory function using isogenic iPSC-derived pancreatic islets. (PubMed, Diabetologia) - "A SUR1 R1420H variant identified in an Indigenous American population causes hyperinsulinaemia in homozygous immature SC-islets during basal conditions and these SC-islets fail to achieve glucose responsiveness after maturation. In the heterozygous state, modest hyperinsulinaemia is observed in immature SC-islets, which after maturation have significantly lower glucose responsiveness. These results demonstrate that SUR1 R1420H is a KATP channel LoF variation and suggest that a lower insulin secretory response during adulthood is the cause of the higher type 2 diabetes risk in individuals heterozygous for this variation. We also show that the isogenic iPSC-based platform can be used to test therapeutic agents to treat HHI in infants homozygous for LoF KATP channels and screen for drugs that can improve glucose-responsive insulin secretion in adult heterozygous carriers."

Case Report: Exogenous insulin antibody syndrome complicated with chronic renal failure and long-term history of type 2 diabetes: report of two cases. (PubMed, Front Endocrinol (Lausanne)) - "In both patients, glycemic fluctuations resolved following insulin discontinuation and the initiation of dorzagliatin, confirming the diagnosis of EIAS. In type 2 diabetic patients with unexplained hypoglycemic and hyperglycemic episodes with a history of exogenous insulin use, pancreatic function and the autoimmune antibody spectrum should be comprehensively evaluated to rule out EIAS and provide an accurate diagnosis and guide treatment strategies."

Genotype-Phenotype Discrepancies in Family Members With a Novel Glucokinase Mutation: Insights Into GCK-MODY and Its Interplay With Insulin Resistance. (PubMed, Diabetes) - "Both dorzagliatin and liraglutide improved glucose tolerance and insulin secretion in mutant mice. We found that GCK-Q26L is a pathogenic mutation leading to GCK-MODY, with severity modulated by polygenic risk score for insulin resistance and type 2 diabetes. These findings not only expand the list of GCK-MODY causing mutations but also highlight the importance of polygenic backgrounds in the clinical presentation and management of monogenic diabetes."

Dorzagliatin enhances GLP-1 secretion by restoring the function of intestinal L-cells (EASD 2025) - "Our study reveals the unique ability of dorzagliatin to promote the synthesis of GLP-1 in intestinal L-cells, while TTP399 lacks this effect. The observed upregulation of Gcg and Pcsk1 genes and increased L-cell abundance further demonstrate the role of dorzagliatin in restoring L-cell function, underscoring its superior therapeutic potential for T2D compared with other GKA, such as TTP399."

An innovative method for simultaneous separation and determination of monosaccharide and sugar alcohol isomers associated with glycometabolism in beagle plasma using gas chromatography-mass spectrometry. (PubMed, Anal Chim Acta) - "This method solves the problems of multiple peaks after derivatization and frequent co-elution of analytes in previous analytical methods, significantly enhances derivatization efficiency of ketoses, which provides a promising approach for simultaneous analysis of aldose, ketose, and sugar alcohol. It offers new insights into a more comprehensive research on glycometabolism rather than merely focusing on glucose."

In Vivo PK-PD and Drug-Drug Interaction Study of Dorzagliatin for the Management of PI3Kα Inhibitor-Induced Hyperglycemia. (PubMed, Pharmaceuticals (Basel)) - "Objectives: The anticancer effects of PI3Kα inhibitors (PI3Ki) are constrained by their hyperglycemic side effects, while the efficacy of conventional hypoglycemic agents, such as insulin, metformin, and SGLT-2 inhibitors, in mitigating PI3Ki-induced hyperglycemia remains suboptimal. Our findings indicate that the drug-drug interactions (DDIs) between dorzagliatin and multiple PI3Ki (including WX390 and BYL719) may partially account for the enhanced antitumor efficacy observed in the combination therapy group compared to PI3Ki monotherapy. This interaction may be explained by the inhibition of P-glycoprotein (P-gp) and the pharmacological mechanism of dorzagliatin regarding the activation of insulin regulation."

Factors influencing the initial glycemic efficacy of dorzagliatin, a novel glucokinase activator, in type 2 diabetes. (PubMed, Endocrine) - "Blood glucose levels of T2DM patients during dorzagliatin initial treatment are positively correlated with diabetes duration, suggesting greater efficacy of dorzagliatin in patients with shorter disease duration. Metformin may enhance the glucose-lowering efficacy of dorzagliatin but also increase the risk of hypoglycemia. Furthermore, factors like baseline FPG, TC and AST also influence outcomes."

Long-Term Administration of Dorzagliatin Combined with Sitagliptin for the Management of Glucose Homeostasis in High-Fat Diet–Induced Obesity Mice (ADA 2025) - "DIO mice have impaired GLP-1 secretion, elevated glucose, insulin and glucagon levels. Following 30 days of treatment, glucose levels were improved with increased secretion of insulin, the combination of GKA and DPP4i was superior to dorzagliatin alone with the improved GLP-1 secretion. Those data indicated that, in addition to increased insulin secretion by GKA, the enhanced GLP-1 secretion also played a significant role in improving glucose homeostasis, and the addition of DPP4i amplified these effects."

A functional and mechanistic explanation for the unique clinical success of the glucokinase activator dorzagliatin for treatment of type 2 diabetes. (PubMed, Diabetes) - "In contrast, dorzagliatin only binds favorably to the closed form of glucokinase, interacting primarily with R63, and causing a low energy barrier for the open-to-close transition. This provides the molecular rationale for the clinical success of dorzagliatin which can guide the future development of next-generation allosteric activators of GK."
