SPS-4251, also known as AS-77 and PAP-1, is a KCNA3 (Potassium voltage-gated channel, shaker-related subfamily, member 3) channel blocker potentially for the treatment of plaque psoriasis. Kv1.3 channels regulate the activation/proliferation of effector memory T cells and thus play a critical role in the pathogenesis of autoimmune diseases. PAP-1 reduced the secretion of TNFα by adipose tissue but had no effect on the secretion of IL-6. PAP-1 can also potentially inhibit the exocytosis of cytoplasmic granules from CD4(+)CD28(null) T cells.
