LAS190792
LAS190792 is a bifunctional muscarinic acetylcholine receptor (mAChR) antagonist and β2-adrenergic receptor agonist. LAS190792 has a pIC50 of 8.8 against human M3 muscarinic receptor and a pIC50 of 9.1 against human β2-adrenergic receptor. LAS190792 exhibits vasodilatory and anti-inflammatory activities, and induces sustained bronchodilation in dogs. LAS190792 inhibits the release of IL-8, MMP9, IL-1β and GM-CSF from lipopolysaccharide-stimulated neutrophils. LAS190792 can be used in research related to respiratory system diseases.

LAS190792 exerts concentration-dependent anti-inflammatory effects in peripheral blood neutrophils derived from patients with chronic obstructive pulmonary disease and their matched controls, with -log IC50 values ranging from 6.8 to 10.3; moreover, when combined with non-effective concentrations of Fluticasone propionate (HY-B0154), it exerts synergistic anti-inflammatory effects in both of these two cell populations[1].
LAS190792 exhibits high-affinity non-selective binding to human M1-M4 muscarinic receptors (pIC50 range 8.8-9.2), has lower affinity for M5, and shows high-affinity selective binding to human β2-adrenergic receptors relative to the β1 and β3 subtypes (pIC50 = 9.1)[2].
LAS190792 shows potent antimuscarinic activity (pIC50 = 8.3) under β2-receptor blockade conditions, and it has a slower onset and longer duration of action than Batefenterol (HY-12980)[2].

LAS190792 (0.03-10 µg/kg; administered via nebulization) exhibits potent bronchoprotective activity with an ED40 of 0.03 µg/kg, and has a wide safety margin, with transient blood glucose changes observed only at the highest tested dose[3].

Animal Model:Beagle (male, 12 kg)[2]
-
Dosage:0.3 µg/kg; 1 µg/kg; 10 µg/kg; 30 µg/kg
-
Administration:nebulized; single dose
-
Result:Demonstrated dose-dependent bronchoprotection with an ID40 of 0.03 µg/kg at 30 min and a 13.3 h protective half-life, retaining obvious bronchoconstriction inhibition at 10 µg/kg for 24 h, with a safety margin of 333.
Caused minor irrelevant heart rate elevation below 10% at 10 µg/kg and marked heart rate rise over 10% only at 30 µg/kg.
