生物活性

製品説明 WT161は、強力で選択的かつ生物学的に利用可能なHDAC6阻害剤であり、HDAC6、HDAC1、およびHDAC2に対してそれぞれ0.4 nM、8.35 nM、および15.4 nMのIC50値を示し、他のHDACと比較して100倍以上の選択性を示します。WT161はアポトーシスを誘発します。
in vitro

WT161 selectively inhibits HDAC6 and dramatically increases levels of acetylated α-tubulin (Ac-α-tubulin) with little effect on global lysine acetylation. It induces accumulation of acetylated tubulin and cytotoxicity in multiple myeloma (MM) cells. This compound as a single agent does not induce ER stress, the UPR, or ER stress-mediated apoptosis. Consistent with this compound mediated hyperacetylation and inhibition of hsp90 chaperone function, treatment with this chemical increases the intracellular levels of polyubiuitylated proteins in the cultured MCL JeKo-1 and Z138 cells. It also dose-dependently depletes the levels of cyclin D1 in the cultured human Mantle Cell Lymphoma (MCL) cells. Treatment with this agent induces ER stress response in the MCL cells, demonstrated by increase in the protein levels of Glucose regulated protein (GRP) 78, phosphorylated eIF2 (eukaryotic initation factor 2) α, and induction of the pro-apoptotic transcription factor CHOP (CAAT/Enhancer Binding Protein Homologous Protein). This compound triggers apoptotic cell death in MCF7, T47D, BT474, and MDA-MB231 cells, associated with decreased expression of EGFR, HER2, and ERα and downstream signaling.

in vivo

WT161 has reasonable half-life in mice (1.4 h) and drug exposure [maximum concentration (Cmax) = 18 mg/L]. It is well tolerated as a single agent. This compound significantly inhibits in vivo MCF7 cell growth, associated with downregulation of ERα, in a murine xenograft model.
