| 名称 | Lomustine |
| 描述 | Lomustine (NSC-79037) is an alkylating agent of value against both hematologic malignancies and solid tumors. |
| 细胞实验 | Cell lines are routinely grown as monolayers in DMEM supplemented with 10% foetal calf serum, 25 mm HEPES, glutamine and penicillin/streptomycin. Cytotoxicity studies are carried out in HEPES-free medium in a 5% CO2 atmosphere. 750-1000 cells/well are plated in 96 well plates and after overnight incubation are treated for 2 hours with or without 33 μM BG. Temozolomide or CCNU is then added for 1 hour in the same medium, the final DMSO concentration not exceeding 1%. The cells are grown for a further 7 days in fresh medium and assayed for protein content by the NCI sulphorhodamine assay; growth studies show that cells are in log phase growth during the assay period. For the repeat temozolomide dosing schedule cells are given consecutive 24 hours treatments, with fresh medium each day. Assays are carried out at least in duplicate.(Only for Reference) |
| 体外活性 | Lomustine inhibits the growth of ZR-75-1 and U373 with IC50 of 12 μM and 15 μM, respectively. Lomustine reduces the level of expression of the DNA repair protein O6-alkylguanine-DNA alkyltransferase. [1] Lomustine (420 μM) triggers apoptosis through the mitochondrial pathway via decrease in the level of the anti-apoptosis proteins Bcl-2 and Bcl-xl, respectively, in both medulloblastoma and normal human epithelial and fibroblast cells. Lomustine induces cell cycle delay in G2/M phase in medulloblastoma cells and up-regulates p21 protein level in a p53-independent manner in HFSN1 cells. [2] |
| 体内活性 | Lomustine can cause delayed, cumulative dose-related, chronic hepatotoxicity that is irreversible and can be fatal. [4] Lomustine could result in infrequent severe hematological toxicity in cats with spontaneously arising tumors, and the incidence of either grade III or IV neutropenia and thrombocytopenia is 4.1% and 1.0%, respectively. Lomustine trends toward a greater likelihood for progressive neutropenia and statistically significant higher response rates in cats with spontaneously arising tumors. [5] |
