Lexibulin dihydrochloride
CAS No. : 917111-49-0
MCE 站:Lexibulin dihydrochloride
产品活性:Lexibulin dihydrochloride (CYT-997 dihydrochloride) 是微管蛋白聚集强效抑制剂,对多种癌细胞的 IC50 值为 10-100 nM,体外体内具有高效的细胞毒性和血管增生阻断作用。Lexibulin dihydrochloride 可诱导细胞凋亡 (apoptosis),并诱导 GC 细胞中的线粒体 ROS 生成。
研究领域:Cell Cycle/DNA Damage | Cytoskeleton | NF-κB | Metabolic Enzyme/Protease | Immunology/Inflammation | Apoptosis
作用靶点:Microtubule/Tubulin | Reactive Oxygen Species | Apoptosis
In Vitro: Lexibulin (CYT-997) prevents the in vitro polymerization of tubulin with an IC50 of ~3 μmol/L (compared with the half-maximal inhibitory concentration of 2 μmol/L for colchicine under identical conditions) as determined using the conventional turbidimetric assay for tubulin polymerization. Lexibulin is also capable of reversibly disrupting the microtubule network in cells, visualized using fluorescence microscopy. Thus, treatment of A549 cells with Lexibulin (1 μM) lead to the rapid reorganization of microtubules, including the destruction of the existing microtubule network and accumulation of tubulin in plaques within the cytoplasm of some cells. After 24 hours, major alterations in cell morphology are evident, including loss of adhesion and cell rounding. The effect of 1 hour of treatment with Lexibulin is reversible and cells rapidly recovered their normal microtubule architecture. Taken together, the data indicates that Lexibulin belongs to the class of anticancer agents that disrupt, rather than stabilize, tubulin-containing structures. Although vehicle-treated cells show 15% and 19% in G2-M phase at 15 and 24 hours (respectively), cells treated with Lexibulin (1 μM) had 38% and 43% of cells in G2-M at the same time points. Furthermore, at 24 hours post-Lexibulin treatment, only 66% of total cells are in the G1, S, and G2-M phases, which suggests that cells blocked at the G2-M boundary do not exit back to G1, as in the normal cell cycle, but most likely are driven towards apoptosis and cell death. Consistent with the disruption of cellular tubulin, Lexibulin potently inhibits proliferation, induces cell cycle arrest and most importantly apoptosis of both human myeloma cell lines (HMCLs) and primary MM cells.
In Vivo: iIn a xenograft model using the human prostate cancer cell line PC3, oral dosing of Lexibulin (CYT-997) is initiated 13 days after cell implantation by which time palpable tumors were evident. A dose-dependent inhibition of tumor growth was apparent with Lexibulin (CYT-997), which at the highest dose was equivalent to parenterally administered paclitaxel. A single dose of Lexibulin (CYT-997) (7.5 mg/kg i.p.) clearly decreased blood flow in liver metastases, and a significant reduction in blood flow was present 6 hours postdose. Lexibulin (CYT-997) treatment (15 mg/kg/day) significantly prolongs the survival in a murine model of aggressive systemic myelomatosis.
