Formula C74H114N20O19S
CAS Number 1370290-58-6
Form Solid
Solubility (25°C) Water 20 mg/mL

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.

Neuropeptide Y (3-36) (human, rat) 

Neuropeptide Y (3-36) (human, rat), a neuropeptide Y (NPY) metabolite formed from dipeptidyl peptidase-4 (DPP4), is a selective Y2 receptor agonist. Neuropeptide Y (3-36) (human, rat) is a NPY metabolite formed from dipeptidyl peptidase-4 (DPP4). Neuropeptide Y (3-36) (human, rat) decreases release of norepinephrine via the Y2 receptor.
