T6611343351-67-7In house
NSC-697923 (2-[(4-methylphenyl)sulfonyl]-5-nitrofuran), a potent inhibitor of UBE2N (ubiquitin-conjugating enzyme E2 N, Ubc13), exhibits its role in inducing cell death in neuroblastoma (NB) cells through two distinct mechanisms. In p53 wild-type NB cells, NSC-697923 promotes the nuclear importation of p53, thereby triggering cell death. Meanwhile, in p53 mutant NB cells, NSC-697923 activates the JNK-mediated apoptotic pathway, leading to cell death. Additionally, NSC-697923 inhibits DNA damage and NF-κB signaling, further contributing to its antitumor activity.

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . A total of 10 animals were administered, and the formula you used is 5% 
DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
(mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.Preparation method for in vivo formula: Take 50 μL DMSO main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O mix well and clarify
main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O mix well and clarifyFor Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
