(R)-(3-amino-4-((3-octylphenyl)amino)-4-oxobutyl)phosphonic acid

In addition to receptor-selective agonists such as SEW2871, competitive S1P receptor antagonists have provided insight into the physiological effects of S1P signaling, particularly involving S1P1.
(R)-3-amino-(3-octylphenylamino)-4-oxobutylphosphonic acid (VPC44116) (S1P1/3 antagonist) and an analog, (R)-3-amino-(3-hexylphenylamino)-4-oxobutylphosphonic acid (W146) (S1P1 antagonist), both were found to increase capillary permeability as measured by Evans blue dye leakage in mouse lung tissue.
