SDZ-MKS 492 (MKS 492) is a selective inhibitor of cyclic GMP-inhibited phosphodiesterase (type III PDE). SDZ-MKS 492 inhibits antigen- or platelet activating factor (PAF)-induced bronchoconstriction and allergic reactions in guinea pigs and rats[1].
MKS 492 relaxes airway smooth muscle in vitro[2].
MKS-492 (3-10 mg/kg; i.v.) inhibits antigen-induced bronchoconstriction in guinea pigs[1].
MKS-492 (1-3 mg/kg; i.v.) inhibits PAF-induced bronchoconstriction and the increase in airway responsiveness to histamine in guinea pigs[1].
MKS-492 (30-100 mg/kg; i.p.) inhibits leukotriene B4 (LTB4)-induced airway eosinophilia in guinea pigs[1].
MKS-492 (10-100 mg/kg; i.p.) inhibits passive cutaneous anaphylaxis and mediator-induced skin reactions in rats[1].
