生物活性

製品説明 YM-58483/BTP2 is a blocker of store-operated Ca2+ entry (SOCE), which regulates the activation of non-excitable cells such as lymphocytes.
in vitro YM-58483 (also known as BTP2) is a selective SOCE blocker that inhibits anti-CD3 antibody-induced sustained Ca2+ influx in Jurkat T cells. It does not cross-react with voltage-operated Ca2+ entry, K+ channels, or Cl− channels. This compound suppresses the CRAC, TRPC3, and TRPC5 channels, and also facilitates the TRPM4 channel. It suppresses cytokine production (IL-2, IL-4, IL-5, IFN-γ, etc.) and proliferation in T cells in vitro. YM-58483 inhibits the spleen cell proliferation associated with MLR by suppressing NF-AT activation via sustained influx of extracellular Ca2+[1]. It potently inhibits IL-2 production and NF-AT-driven promoter activity, but not AP-1-driven promoter activity in Jurkat cells[2].
in vivo YM-58483 (BTP2) exhibits inhibitory effects on several types of allergic asthma models, such as airway hyperresponsiveness, early and late bronchoconstriction, and antigen-induced airway eosinophilia, with the reduction of IL-4 and leukotriene levels in the airways of rats and guinea pigs. It also inhibits the anti-host CTL response, donor T cell expansion, and IFN-γ production in GVHD mice. This compound selectively inhibits store-operated Ca²⁺ influx and does not affect baseline intracellular Ca²⁺ levels. It caused no apparent change in general activity in mice at doses up to 30 mg/kg, p.o.[1].

実験の流れ

Jurkat cells (1×107 cells/ml) were treated with varying concentrations of YM-58483 (BTP2) for 30 min at 37°C. After this incubation, the cells were stimulated with 1 μM ionomycin for 30 min at 37°C. Following stimulation, the cells were centrifuged at 200×g for 2 min and solubilized in 100 μl of Triton X-100 lysis buffer. The cell lysate was centrifuged at 15,000×g for 20 min; the clarified lysate was subjected to SDS-PAGE; and NF-ATc2 was detected by Western blotting with anti-NF-ATc2 mAb.
