Sodium cromoglicate is a mast cell stabilizer with anti-inflammatory activity that prevents the release of inflammatory chemicals such as histamine, leukotrienes from mast cells.

PACAP (1-38), a novel neuropeptide isolated from the bovine hypothalamus is more active than vasoactive intestinal peptide (VIP) in stimulating adenylate cyclase (EC50=7 nM). PACAP 1-38 (10-9 M) increased substance P (SP), gastrin releasing peptide (GRP), and VIP release. PACAP 1-38 (10-8 M) inhibited gastrin secretion and stimulated somatostatin secretion and motility dose-dependently.

Atrial natriuretic factor (1-28) (human, porcine) exhibits blood pressure lowering activity by increasing sodium and urine excretion. Atrial natriuretic factor (1-28) (human, porcine) inhibits the release of pituitary adrenocorticotropic hormone (ACTH) and beta-endorphin through inhibition of pro-opiomelanocortin (POMC) expression. Atrial natriuretic factor (1-28) (human, porcine) increases cGMP levels in RMIC cells with an IC50 of 1.2 nM.
