Potent and selective corticotrophin releasing factor receptor 1 (CRF1) agonist (EC50 = 0.18 nM for rat CRF1). Displays anxiolytic and antidepressant activity in vivo. Microinfusion into mouse prefrontal cortex reduces defensive behavior in vivo.

Endotoxin inhibitor a synthetic peptide that binds lipid A with high affinity, thereby detoxifying LPS and preventing LPS-induced cytokine release in vivo. Endotoxin inhibitor inhibits the febrile response to LPS with very low toxicity and lethality.

pTH (13-34) (human) is apTH ((Human parathyroid hormone) fragment.
