DescriptionLLY-283 is an inhibitor of protein arginine methyltransferase 5 (PRMT5; IC50 = 22 nM). It is selective for PRMT5 over a panel of methyltransferases, including PRMT4, -6, and -7 at 1 μM. It reduces symmetric demethylation of SmBB'' in MCF-7 cells (IC50 = 25 nM) and inhibits proliferation of various breast, gastric, hematological, lung, skin, and ovarian cancer cell lines (IC50s = 3-30 nM). LLY-283 (20 mg/kg) inhibits tumor growth in an A375 mouse xenograft model. It also disrupts alternative splicing events in, and inhibits proliferation and self-renewal of, patient-derived glioblastoma stem cells and increases survival in an orthotopic patient-derived xenograft (PDX) mouse model. See the Structural Genomics Consortium (SGC) website for more information.
UsesLLY-283 is a potent, selective and oral protein arginine methyltransferase 5 (PRMT5) inhibitor, with an IC50 of 22 nM and a Kd of 6 nM for PRMT5:MEP50 complex, and shows antitumor activity.
in vivo

LLY-283 (20 mg/kg; p.o., QD (once a day)) causes a significant inhibition on tumor growth in mice bearing A375 cells after treatment for 28 days[1].
