D5B

😃Good
Catalog No. T203184

D5B is an effective and selective PD-L1 inhibitor that has been modified with DBCO. It degrades PD-L1 in 4T1 and B16-F10 tumor cells with EC50 values of 5.4 μM and 6.2 μM, respectively. D5B can block the PD-L1/PD-1 interaction and exhibits antitumor activity.

Product Introduction

Bioactivity
Description
D5B is an effective and selective PD-L1 inhibitor that has been modified with DBCO. It degrades PD-L1 in 4T1 and B16-F10 tumor cells with EC50 values of 5.4 μM and 6.2 μM, respectively. D5B can block the PD-L1/PD-1 interaction and exhibits antitumor activity.
In vitro
D5B (0-10 μM; 24 hours) degrades PD-L1 in 4T1 and B16-F10 tumor cells, with EC50 values of 5.4 μM and 6.2 μM, respectively. Additionally, D5B (0-5 μM; 48 hours) significantly reduces the abundance of PD-L1 on the cell membrane surface in IFN-γ treated and azide-labeled 4T1 and B16-F10 tumor cells.
In vivo
Administered intravenously at a single dose of 5 mg/kg, D5B exhibits anti-tumor activity in mouse tumor models, with enhanced efficacy when combined with radiotherapy. (D5B refers to PCPGd@D5B nanoparticles).

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:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent 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 DMSOTargetMol | reagent (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 DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
