生物活性
产品描述 |
一种拓扑异构酶抑制剂Daunorubicin的前药。 |
|
靶点 |
Topoisomerase |
Daunorubicins/Doxorubicins |
体外研究 |
Daun02 is a prodrug, which is converted by β-galactosidase to Daunorubicin, which has been shown to reduce calcium ion (Ca2+)-dependent action potentials in neuroblastoma cells. Daunorubicin is a topoisomerase inhibitor. Daun02 is a good substrate for β-galactosidase (β-gal). The concentration of Daun02 producing 50% (EC50) decrease in cell viability is 0.5μM, 1.5μM, and 3.5μM for T47-D, Panc02, and MCF-7, respectively |
|
体内研究 |
Daun02 is a good substrate for β-gal with Km and Vmax values of 0.37mM and 8.6μMol/min/mg protein. At a concentration of 10-5 M, Daun02 is 79% bound to plasma protein compares to 94% for Daunomycin |
推荐实验方法(仅供参考)
Cell Assay |
Murine Panc02 cells are maintained as exponentiallygrowing monolayer cultures in DMEM/F12 or RPMI-1640 medium supplemented with 10% FBS, 1% glutamine, penicillin, and streptomycin at 37°C. For cytotoxicity assay, the cells are seeded into 96-well microplates and incubated overnight. Initial experiments indicate that FBS contains low levels of intrinsic β-gal activity as evidenced by the slow conversion of Daun02 to Daunomycin; however, this is not evident for human serum. Therefore, prior to addition of Daun02, the FBS concentration is reduced from 10% to 1% for Panc02 cells. Human serum (10%) is used for the transduced human cell lines. The cells are incubated for 24 h and then MTT is added. Lysis buffer (20% SDS dissolved in 50% DMF) is added 4 h after the addition of MTT and the cells are incubated overnight. The optical density at 570 nm is determined using a BIO-RAD microplate reader. Cytotoxicity is expressed as the concentration of drug or prodrug that produced a 50% (EC50) reduction in cell viability |
Animal Administration |
Mice Male athymic BALB/c mice (nu/nu genotype, 18-20 g) are used. Daunomycin is administered at a dose of 20 mg/kg in 100μL normal saline solution into the tail vein. Daun02 is administered intraperitoneallyat a dose of 200 mg/kg in 200μL vehicle. (This route is selected because the volume of drug solution, 200μL, is too great for tail vein administration.) Tumor volume is determined bycaliper measurement in two dimensions and converted to tumor mass. Tumor growth is monitored over a period of 30 days or until the tumors has reached a mass of 5% of bodyweight (about 1 g). The animals are then killed bycarbon dioxide asphyxiation. |
