insulin secretion

Vincamine (Perval) is a major alkaloid of Vinca minor L., Apocynaceae. It has been used therapeutically as a vasodilator and antihypertensive agent, particularly in cerebrovascular disorders.

trans-Cinnamic acid (Myricitrine) exerts anti-diabetic activity by improving glucose tolerance in vivo and by stimulating insulin secretion in vitro.

(2S,3R,4S)-4-Hydroxyisoleucine (Hydroxyisoleucine) from fenugreek (Trigonella foenum-graecum) seeds is a potential insulinotropic (anti-diabetic) and anti-obesity amino acid that stimulates glucose-dependent insulin secretion from pancreatic cells, activates insulin receptor substrate-associated phosphoinositide 3 (PI3) kinase activity, and reduces plasma levels of triglycerides, free fatty acids, and cholesterol.

Taurochenodeoxycholic acid sodium (Sodium taurochenodeoxycholate) is one of the main bioactive substances of animals' bile acid. Taurochenodeoxycholic acid sodium induces apoptosis and shows obvious anti-inflammatory and immune regulation properties. It can increase glucose-induced insulin secretion and stimulate the electrical activity of α2-cells and enhance cytosolic Ca(2+) concentration ([Ca(2+)](c)).

Propane-1,2,3-triyl tripalmitate (Glycerol Tripalmitate) is a triacylglycerol found in dietary fats. In hamsters fed a diet enriched with it, Tripalmitin increases body weight, elevates plasma LDL levels, and reduces hepatic LDL receptor mRNA levels. It inhibits glucose-stimulated insulin secretion and decreases the viability of INS1 cells dose-dependently. Tripalmitin is used in cosmetic products for skin conditioning and as a thickening agent, and it forms lipid matrices of nanoparticles for drug delivery.

Chikusetsusaponin IVa (Calenduloside F) is a novel AMPK activator, can induce insulin secretion from βTC3 cells via GPR4 mediated calcium and PKC pathways, may be developed into a new potential for therapeutic agent used in T2DM patients.

Kazinol B is an inhibitor of nitric oxide (NO) production, an isopentenylated flavan with a dimethylpyran ring.Kazinol B improves insulin sensitivity by activating the insulin-Akt signalling pathway and AMPK, which enhances glucose uptake.Kazinol B stimulates gene expression and secretion of adiponectin and can be used to study diabetes.

Rhoifolin (Apigenin 7-O-neohesperidoside) is extracted from Turpinia arguya Seem dried leaves.

Cinnamtannin A2 is a natural product and procyanidin tetramer that enhances GLP-1 and insulin secretion in mice. It protects against renal injury by reducing KIM-1 and NGAL expression and exhibits antioxidant activity.

1. Apigenin 7-glucoside (Cosmosiin) is a anti-HIV agent. 2. Cosmosiin may be beneficial for diabetic complications through their enhanced adiponectin secretion, tyrosine phosphorylation of insulin receptor-β and GLUT4 translocation.

Lupanine ((+)-Lupanine), a naturally occurring quinolizidine alkaloid, potently affinity and activates nicotinic acetylcholine receptor (nAChR) (Ki=500 nM), and shows significant neuroprotection against soluble amyloid β-oligomers (SO-Aβ) toxicity in cellular models in association with the anti-apoptotic PI3K/ Akt/Bcl-2 signaling pathway with anti-Alzheimer's disease potential. Improves glucose homeostasis by affecting KATP channels and enhancing insulin secretion with therapeutic potential for type 2 diabetes.

Lo Han Kuo extract is a high intensive sweetening agent with desirable health benefits, such as prevention of dental caries through specific antibacterial properties, no-calorie levels related to obesity, and a low glycemic index to help manage blood suga

Momordicine II may have antidiabetic activity, it significantly stimulated insulin secretion. It also can deter oviposition by L. trifolii significantly.

Momordicoside X displays moderate insulin secretion activity.

Serpentine is an alkaloid found in the roots of Rosa Centifolia that acts as an insulin sensitizer to assist insulin in lowering blood glucose.Serpentine activates the phosphorylation of AMPK, which stimulates glucose uptake by C2C12 cells.Serpentine increases the expression of GSK-3β mRNA in muscle tissues, which enhances glucose uptake.Serpentine also increases glucose production and hepatic gluconeogenesis.Serpentine has a significant effect on glucagon secretion and hepatic gluconeogenesis. Serpentine significantly increased glucagon secretion and hepatic gluconeogenesis. In high-fat diet/streptozotocin (HFD/STZ)-induced diabetic mice, Serpentine significantly prolonged insulin hypoglycemia, significantly decreased exogenous insulin use, and inhibited endogenous insulin secretion.

1. Incensole has a protective or stimulating effect on β-cells of the rat pancreas, it also can increase the insulin secretion, which evidenced by a significant increase both in body weight and in liver glycogen.
