Product Introduction

Bioactivity
Description
D4-abiraterone is the active metabolite of abiraterone produced by 3β-HSD and is further metabolised by SRD5A.Δ4-Abiraterone is an inhibitor of CYP17A1, 3β-HSD and SRD5A, and an antagonist of the androgen receptor.
Targets&IC50
Androgen receptor:5.3-7.9 nM
In vitro
D4-abiraterone (10 μM) nearly fully blocks AD conversion to 5α-androgens. D4-abiraterone binds AR more strongly (IC₅₀ = 5.3-7.9 nM) than abiraterone (IC₅₀ = 418-500+ nM), and more effectively suppresses AR target genes like PSA[1].
In vivo
In LNCaP and VCaP mouse tumors, D4-abiraterone was 10× stronger than abiraterone. At 0.1 μM, D4-abiraterone matched 1 μM abiraterone in blocking AD formation and delayed tumor growth within 48 h[1].

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% Saline/PBS/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 μLSaline/PBS/ddH2OTargetMol | reagent mix well and clarify
