Cayman AS-101

AS-101 is an immunomodulator. It inhibits IL-10 secretion from and cell proliferation of IL-10-secreting human stomach adenocarcinoma and glioblastoma multiforme (GBM) cells when used at concentrations ranging from 0.5 to 2.5 µg/mL, an effect that can be blocked by the addition of recombinant IL-10. It reverses IL-10-induced increases in phosphorylated Stat3 and reduces the expression of Bcl-2 in B16 murine melanoma cells. AS-101 sensitizes GBM cells to paclitaxel (Item No. ), doxorubicin (Item No. ), and 5-fluorouracil (5-FU; Item No. ) in vitro and to paclitaxel in a GBM mouse xenograft model when administered at a dose of 0.5 mg/kg per day. AS-101 (1 mg/kg) also prevents infiltration of CD49d⁺ cells and decreases the expression of IL-6, TNF-α, IL-1β, and MCP-1 in the spinal cord, as well as delays onset and slows the progression of symptoms in a mouse model of experimental autoimmune encephalomyelitis (EAE).
