| Description | Polymyxin B nonapeptide is a cyclic peptide obtained from Polymyxin B by proteolytic removal of its terminal amino acyl residue. Polymyxin B nonapeptide is less toxic, lacks bactericidal activity, and retains its ability to render gram-negative bacteria susceptible to several antibiotics by Polymyxin B nonapeptide is a cyclic peptide obtained from Polymyxin B by proteolytic removal of its terminal amino acyl residue. Polymyxin B nonapeptide is less toxic, lacks bactericidal activity, and retains its ability to render gram-negative bacteria susceptible to several antibiotics by permeabilizing their outer membranes[1][2][3]...

Endomorphin 1 acetate has antinociceptive properties[1][2][4] | 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] | pTH (39-84) (human) is a parathyroid hormone (PTH) C-terminal fragment. pTH (39-84) (human) stimulates osteoclast formation[1] |
