SN-38 is an active metabolite of CPT-11, inhibits DNA topoisomerase I, DNA synthesis and causes frequent DNA single-strand breaks.
|Source||Customer experimental result (2018).|
|Method||Cell viability assay|
|Cell Lines||MDA-MB-231 cells|
|Incubation Time||4 days|
|Results||MDA-MB-231 cells were treated with 32nM SN-38 for 4 days and then incubated for 4 days. Most of the MDA-MB-231 cells were transformed into senescent cells.|
|Source||J Immunol Res (2018). Figure 1. SN-38|
|Cell Lines||NB cell lines|
|Incubation Time||24 hours|
|Results||Cisplatin at 2 μM, etoposide at 0.1 μM, irinotecan at 1 nM, and topotecan at 10nM induced apoptosis of all NB cell lines after 48 hours of treatment, with the exception of SK-N-AS treated with the first three drugs and SK-N-BE(2)c treated with all four drugs|
|Cell lines||A-172, U-87, and LA-567|
|Preparation method||MTT assay|
|Concentrations||0 -1000 nM|
|Incubation time||48 h|
|Animal models||Nontumor-bearing mice|
|Formulation||dissolved in DMSO (1 mg/mL)|
|Body Surface Area (m2)||0.007||0.025||0.15||0.05||0.02||0.5|
|Animal A (mg/kg) = Animal B (mg/kg) multiplied by||Animal B Km|
|Animal A Km|
For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
|Solubility||DMSO 10 mg/mL|
