Biological Activity

IRL 2500 is a potent Endothelin receptor antagonist. IRL 2500 shows IC50 values of 1.3 and 94 nM for ETB and ETA receptors, respectively. IRL 2500 inhibits ETB receptor-mediated blood pressure increase and renal vascular resistance in rats in vivo.

Chemical Information
Molecular Weight 573.68
Formula C36H35N3O4
CAS Number 169545-27-1
Form Solid
Solubility (25°C) DMSO 100 mg/mL (ultrasonic)
Storage 4°C, dry, sealed
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.
