Description: Upadacitinib, also known as ABT-494, is a potent and selective JAK inhibitors in development for rheumatoid arthritis. ABT-494 is approximately 74 fold selective for Jak1 over Jak2 in cellular assays dependent on specific, relevant cytokines. ABT-494 demonstrates efficacy in rat arthritis models. Preliminary evidence suggests that compared to tofacitinib, ABT-494 may spare Jak2 and Jak3 dependent signaling.

Synonym: ABT-494; ABT 494; ABT494. Upadacitinib.

IUPAC/Chemical Name: (3S,4R)-3-ethyl-4-(3H-imidazo[1,2-a]pyrrolo[2,3-e]pyrazin-8-yl)-N-(2,2,2-trifluoroethyl)pyrrolidine-1-carboxamide
