AS1517499 inhibit IL-4-induced Th2 differentiation of mouse spleen T cells, but has no influence on Th1 differentiation induced by IL-12. AS1517499 is able to prevent the IL-4-activated STAT6-mediated increase of the clonogenic potential of primary PCa cells. At a dose of 300 nM, AS1517499 decreases the clonogenic potential of primary basal PCa cells.
In vivo
In vivo treatment with AS1517499 ameliorates the antigen-induced bronchial smooth muscle (BSM) hyperresponsiveness by inhibiting the RhoA up-regulation in BSMs and, at least in part, by reducing the IL-13 production in the airways in mice. AS1517499 reduces preventive effects of apoptotic cell instillation on bleomycin-induced lung fibrosis by suppressing PPARγ.
