Cell experiment: | The cytotoxicity assay is performed with MTT. Cells are seeded in 96-well culture plates (5000 cells/well) and incubated for 24 h for stabilization. After this period, the following treatments are administered for 24 and 48 h: vehicle control (0.5 % DMSO); 1 μM doxorubicin and monastrol at 5, 25, 50, 75, and 100 μM. After each time of treatment, the medium is withdrawn, serum-free media containing 0.5 mg/mL MTT salt is added and incubated for 4 h, and formazan crystal products are diluted[2]. |
| 产品描述 | IC50: 14 μM Monastrol is a cell-permeable small molecule inhibitor of the mitotic kinesin, Eg5. Like other kinesins, Eg5 can drive the movement of microtubules in vitro. In vitro: Previous study found that monastrol did not inhibit progression through S and G2 phases of the cell cycle or centrosome duplication. The mitotic arrest due to monastrol was also reversible rapidly. Chromosomes in monastrol-treated cells frequently had both sister kinetochores attached to microtubules extending to the center of the monoaster. Monastrol also inhibited bipolar spindle formation in Xenopus egg extracts, however, monastrol did not prevent the targeting of Eg5 to the monoastral spindles that form [1]. In vivo: Previous study investigated the rat PK and TK of LaSOM 65, a monastrol derivative. Results showed that LaSOM 65 had good bioavailability and linear PK after oral doses. LaSOM 65 distributed consistently in lung and fatty tissues. Other investigated tissues presented smaller penetration ratios. Adverse symptoms were observed only after iv administration, and regressed 3 h after dosing. No statistical differences were found for serum analysis, body weight and relative organ weight, indicating no acute toxicological effects. [2]. Clinical trial: Up to now, LaSOM 65 is still in the preclinical development stage. References: |
