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].

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 . 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 DMSO TargetMol | 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 DMSO TargetMol | reagent

main solution, add 300 μLPEG300 TargetMol | reagent

mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline/PBS/ddH₂O TargetMol | reagent

mix well and clarify
