Chemicals & Small Molecules

Apelin-17(human, bovine) (Legacy Tebubio ref. 282TP2092). Endogenous apelin receptor agonist. Potently inhibits forskolin-stimulated cAMP accumulation (pIC50 = 9.94).

Apelin-17 (human, bovine) acetate (Legacy Tebubio ref. 282TP2092L). Apelin-17 (human, bovine) acetate is an endogenous apelin receptor agonist. Potently inhibits forskolin-stimulated cAMP accumulation (pIC50 = 9.94).

Apelin-36(human) (Legacy Tebubio ref. 282TP2093). Endogenous APJ receptor agonist (EC50 = 20 nM) that is secreted by adipocytes. Binds with high affinity to human APJ receptors expressed in HEK 293 cells (pIC50= 8.61). Involved in regulation of cardiovascular function, fluid homeostasis and feeding. Blocks entry of some HIV-1 and HIV-2 strains into NP-2/CD4 cells expressing APJ.

Apelin-36(rat, mouse) (Legacy Tebubio ref. 282TP2094). Endogenous APJ receptor agonist that is secreted by adipocytes. Binds with high affinity to APJ receptors (IC50 = 5.4 nM) and potently inhibits cAMP production in vitro (EC50 = 0.52 nM). Involved in regulation of cardiovascular function, fluid homeostasis and feeding. Blocks entry of some HIV-1 and HIV-2 strains into NP-2/CD4 cells expressing APJ.

Astressin 2B (Legacy Tebubio ref. 282TP2095). Potent and selective corticotropin-releasing factor receptor 2 (CRF2) antagonist (IC50 values are 1.3 and > 500 nM for CRF2 and CRF1 respectively). Antagonizes CRF2-mediated inhibition of gastric emptying.

ELA-21 (human) (Legacy Tebubio ref. 282TP2096). High affinity apelin receptor agonist. Binds apelin receptors in left ventricle from normal and pulmonary arterial hypertensive (PAH) hearts (pKi values are 9.31 and 9.46, respectively). Bioactive fragment of ELA-32. Inhibits forskolin-induced cAMP production and stimulates β-arrestin recruitment in vitro.

ELA-32(human) (Legacy Tebubio ref. 282TP2097). Potent, high affinity apelin receptor agonist (IC50 = 0.27 nM; Kd = 0.51 nM). Exhibits no binding GPR15 and GPR25. Activates the PI3K/AKT pathway and promotes self-renewal of hESCs via cell-cycle progression and protein translation. Also potentiates the TGFβ pathway, priming hESCs toward the endoderm lineage. Stimulates angiogenesis in HUVEC cells. Relaxes mouse aortic vessels. Functions as an anorexigenic hormone through activation of the AVP and CRH neurons in the PVN.

Echistatin (Legacy Tebubio ref. 282TP2098). Potent irreversible αVβ3 integrin antagonist (Ki = 0.27 nM). Disrupts attachment of osteoclasts to bone and inhibits bone reabsorption (IC50 = 0.1 nM). Prevents ADP-induced platelet aggregation via inhibition of glycoprotein IIb/IIIa (GpIIb/IIIa, αIIbβ3) receptors (IC50 = 30 nM) in vitro.

[Ala1,3,11,15]-Endothelin (Legacy Tebubio ref. 282TP2099). Selective ETB endothelin receptor agonist (IC50 values are 0.33 and 2200 nM for displacing [125I]-ET-1 from ETB and ETA receptors respectively).
