用途

醋酸四烯物(21-羟基孕甾-1,4,9(11),16-四烯-3,20-二酮-21-醋酸酯,3TR)是合成曲安奈德、地塞米松、布地奈德等甾体药物的重要中间体

生物活性

21-Acetoxypregna-1,4,9(11),16-tetraene-3,20-dione 是 delta 9,11 类固醇类合成的中间体 (intermediate)，如 Vamorolone (HY-109017)。delta 9,11 steroids 是糖皮质激素的修饰后的产物，具有抗炎 (anti-inflammatory) 特性。delta 9,11 类固醇类可以用作保护细胞损伤(脂质过氧化)和抑制新生血管的试剂。

体外研究

Δ9,11 derivatives are designed and developed to stably incorporate into cell membranes and inhibit lipid peroxidation without glucocorticoid or mineralocorticoid activities, thus avoiding side effects associated with traditional corticosteroids. VBP15 acts as a lead compound due to potent NF-κB inhibition and GR translocation similar to prednisone and dexamethasone, lack of transactivation properties, and good bioavailability.

用途 

地塞米松、倍他米松、确炎舒松的中间体。
