Biological Activity

Ro 6842262 (LPA1 receptor antagonist 1) is an orally bioavailable, highly selective Lysophosphatidic Acid receptor-1 (LPA1) antagonist with an IC50 of 25 nM. Ro 6842262 attenuates NHLF human lung fibroblast cell proliferation and contraction in vitro. Ro 6842262 also reduces plasma histamine levels in mouse LPA-challenge model.

Chemical Information

Formula C28H26N4O4
CAS Number 1396006-71-5
Storage Store at -20°C
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.
