Lexibulin(CYT-997) is a potent tubulin polymerisation inhibitor with IC50 of 10-100 nM in cancer cell lines; with potent cytotoxic and vascular disrupting activity in vitro and in vivo.IC50 value: 10-100 nM(cell assay) [1]Target: tubulin polymerisation inhibitor in vitro: CYT997 prevented 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. CYT997 was also capable of reversibly disrupting the microtubule network in cells, visualized using fluorescence microscopy. Thus, treatment of A549 cells with CYT997 (1 μmol/L) 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 were evident, including loss of adhesion and cell rounding. The effect of 1 hour of treatment with CYT997 was reversible and cells rapidly recovered their normal microtubule architecture. Taken together, the data indicates that CYT997 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 CYT997 (1 μmol/L) had 38% and 43% of cells in G2-M at the same time points. Furthermore, at 24 hours post-CYT997 treatment, only 66% of total cells were 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 [1]. Consistent with the disruption of cellular tubulin, CYT997 potently inhibits proliferation, induces cell cycle arrest and most importantly apoptosis of both human myeloma cell lines (HMCLs) and primary MM cells [2].in vivo: In a xenograft model using the human prostate cancer cell line PC3, oral dosing of CYT997 was initiated 13 days after cell implantation by which time palpable tumors were evident. A dose-dependent inhibition of tumor growth was apparent with CYT997, which at the highest dose was equivalent to parenterally administered paclitaxel. A single dose of CYT997 (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 [1]. CYT997 treatment (15 mg/kg/day) significantly prolongs the survival in a murine model of aggressive systemic myelomatosis [2].
