Description: | iJak-381 (iJak381) is a potent, selective inhalable and lung-restricted inhibitor of JAK1 with IC50 of 8.52 nM, displays 6.3/704/28 fold selectivity over JAK2/JAK3/TYK2; suppresses STAT 6 activation by IL-1, suppresses ovalbumin-induced lung inflammation in both murine and guinea pig asthma models and improved allergen-induced airway hyperresponsiveness in mice; In a model driven by human allergens, iJak-381 had a more potent suppressive effect on neutrophil-driven inflammation compared to systemic corticosteroid administration, reduces lung pathology without affecting systemic Jak1 activity in rodents. |
