Biological Activity

Gastrin-I (human) is the endogenous peptide produced in the stomach, which increases gastric acid secretion via cholecystokinin 2 (CCK2) receptor. Gastrin-I (1.5, 5, 15 and 45 nmol/kg, i.v.) increases pepsinogen and acid secretion in rats.

Formula C97H124N20O31S
CAS Number 10047-33-3
Solubility (25°C) Water 10 mM (alkaline condition, NH3·H2O adjustment)

Conversion of different model animals based on BSA (PMID: 27057123)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
