常見問題列表
生物活性
Reveromycin A 是一種從鏈霉菌屬中分離出來的苯甲醌類抗生素 (antibiotic)，是選擇性的真核細胞中蛋白質合成 (protein synthesis) 抑制劑。Reveromycin A 通過誘導破骨細胞的凋亡 (apoptosis) 來抑制骨吸收。Reveromycin A 對腫瘤細胞系具有抗增殖活性，并具有抗真菌 (antifungal) 活性。體外研究
Reveromycin A inhibits protein synthesis in osteoclasts (OCs) by selectively blocking enzymatic activity of isoleucyl-tRNA synthetase.
Reveromycin A (0.3-30 μM; for 24 h) induces apoptosis in OCs through inhibition of protein synthesis.
體內研究
Reveromycin A (20 mg/kg; twice daily; i.v.; for 3 days) significantly decreases numbers of OCs without affecting numbers of osteoblasts in normal 4-week-old male Sprague-Dawley rats.
