Taspoglutide acetate ITM077 acetate; R1583 acetate; BIM51077 acetate	GLP Receptor	Metabolic Disease
Taspoglutide (R1583) acetate is an agonist of the glucagon-like peptide 1 receptor (GLP-1R) with an K_i value of 1.1 nM. Taspoglutide acetate induces cAMP accumulation in CHO-K1 cells expressing human GLP-1R (EC₅₀ = 0.06 nM). Taspoglutide acetate decreases blood levels of glucose and increases blood levels of insulin in a glucose tolerance test in Zucker diabetic obese rats. Taspoglutide acetate reduces blood levels of gastric inhibitory polypeptide (GIP), plasma levels of triglycerides, and body weight in the same model .

HY-113513

5-HEPE	Others	Cancer
5(S)-HEPE is an active metabolite of eicosapentaenoic acid. It is formed from EPA by 5-lipoxygenase (5-LO). 5(S)-HEPE is an agonist of G protein-coupled receptor 119 (GPR119). It increases cAMP accumulation in CHO-K1 cells expressing human GPR119 when used at a concentration of 10 μM. 5(S)-HEPE increases glucose-induced insulin secretion from MING6 insulinoma pancreatic islets and glucagon-like peptide 1 (GLP-1) secretion from HuTu 80 adenocarcinoma cells when used at a concentration of 10 μM. Serum levels of 5(S)-HEPE are elevated in patients with hyperlipidemia.

HY-P10843

R4K1	Estrogen Receptor/ERR	Cancer
R4K1 is a cell-permeable stapled peptide. R4K1 binds to the estrogen receptor (ER) α with high affinity and inhibits its interaction with coactivators. R4K1 can enter breast cancer cells to regulate gene transcription and inhibit cell proliferation. R4K1 can be used in the study of cancer .

HY-P1602

Apidaecin IB	Bacterial	Infection
Apidaecin IB is a insect antimicrobial peptide, with minimum inhibitory concentration (MIC) values of 8 μM for E. coli (ML35, O18K1H7 and ATCC 25922).

HY-P1925A

GO-203 TFA 2 Publications Verification	PI3K Reactive Oxygen Species Apoptosis	Cancer
GO-203 TFA is a potent MUC1-C oncoprotein inhibitor. GO-203 TFA is an all D-amino acid peptide that consists of a poly-R transduction domain linked to a CQCRRKN motif that binds to the MUC1-C cytoplasmic tail and blocks MUC1-C homodimerization. GO-203 TFA downregulates TIGAR (TP53-induced glycolysis and apoptosis regulator) protein synthesis by inhibiting the *PI3K-AKT-S6K1* pathway. GO-203 TFA induces the production of ROS and loss of mitochondrial transmembrane potential. GO-203 TFA inhibits the growth of colon cancer cells in vitro and as xenografts in nude mice .
