| Description | Phrixotoxin-1 (TFA), from the venom of the theraphosid spider Phrixotrichus auratus, is a specific peptide inhibitor of Kv4 potassium channel[1][2] | Elastase, Porcine pancreas (EC 3.4.21.36) is a single polypeptide chain of 240 amino acid residues, derived from pig pancreas. Elastase, Porcine pancreas is a serine protease that can hydrolyze proteins and polypeptide. Elastase from porcine pancreas can induce emphysema in hamsters[1][2][3] | Mastoparan, a tetradecapeptide which is a component of wasp venom, stimulates release of prolactin from cultured rat anterior pituitary cells | Mastoparan X is a GTP-binding regulatory protein (G protein)-activating peptide, and a tetradecapeptide from wasp venom. Mastoparan X acts function by the direct activation of G protein that couple to phospholipase C to cause secretion from various kinds of cells[1] | PG-931, an analog of SHU 9119 (HY-P0227), is a potent melanocortin 4 (MC4) receptor (IC50=0.58 nM) agonist and is more selective than for the hMC3R (IC50=55 nM) or the hMC5R (IC50=2.4 nM). PG-931 can reverse haemorrhagic shock and prevent multiple organ damage in vivo[2] |
