GSK-2981278

GSK-2981278 is a highly potent and selective inverse agonist of retinoic acid receptor-related orphan receptor gamma (ROR gamma). GSK-2981278 is a strong RORγ-selective inverse agonist that inhibits activation of the il17 promoter. GSK-2981278 robustly inhibits RORγ-mediated cytokine production at both the mRNA and protein level. GSK-2981278 attenuates inflammation in a mouse model of psoriasis. Topical treatment with GSK-2981278 will significantly limit Th17-type cytokine expression and should therefore lead to improved clinical outcomes for patients.

How to use

In Vitro:

GSK-2981278 markedly and potently inhibits IL-17A and IL-22 protein secretion in a concentration dependent manner (IC50 = 3.2 nM) during 5 days of culture under Th17 skewing conditions. GSK-2981278 (0.3, 1, 3, 10, 30, 100, 300, 1000 pM; 5 day) potently and selectively inhibits IL-17 and IL-22 levels. Culture in the presence of ≥3 nM GSK-2981278 led to a near-complete inhibition of IL-17A protein secretion.

In Vivo:

GSK-2981278 (1% in ointment; topically; for three days) reduces skin redness and scaling, as well as decreased hyperplasia, as evidenced by a 23% reduction in epidermal thickness. GSK-2981278 attenuates inflammation in a mouse model of psoriasis.
