Product Introduction

Bioactivity
Description
Peldesine (BCX 34) is an effective, competitive, reversible, and orally active inhibitor of purine nucleoside phosphorylase. Peldesine inhibits T-cell proliferation with an IC50 of 800 nM. Peldesine can be used in research on cutaneous T-cell lymphoma, psoriasis and HIV infection.
Targets&IC50
RBC PNP (mouse):32 nM , RBC PNP (human):36 nM , Proliferation (human T cells):800 nM , PNP (rat red blood cells):5 nM
In vitro
The IC50s are 36 nM, 5 nM, and 32 nM for human, rat, and mouse red blood cell purine nucleoside phosphorylase, respectively. In Jurkat cells, Peldesine (BCX 34; 0-50 µM; 72 hours) inhibits the T-cell proliferation completely at a concentration of less than 10 μM, in the presence of dGuo (10 μM). In contrast, the B-cell proliferation is not affected by Peldesine[1].
In vivo
Peldesine demonstrates oral efficacy by elevating plasma inosine levels in rats (2-fold at 30 mg/kg), significantly reducing ex vivo red blood cell (RBC) purine nucleoside phosphorylase (PNP) activity in rats (98% at 3 hours, 100 mg/kg), and moderately suppressing ex vivo skin PNP activity in mice (39% at 3 hours, 100 mg/kg). Additionally, Peldesine exhibits an oral bioavailability of 76% in rats[2].

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
