制备方法与用途

性质 格尔德霉素是一种黄色针状物质,稍溶于水,微溶于甲醇、乙醇、丙酮和乙酸乙酯等有机溶剂,并能溶解在氯仿和二甲亚砜中。干品稳定,但在溶液状态下对酸、碱、光和热不稳定。

药理作用 格尔德霉素具有抗原虫、抗肿瘤及抑制革兰氏阳性菌(G+)生长的活性。体内实验显示,GDM能够抑制多种病毒的复制,并且在体外对疱疹病毒感染的不同模型具有治疗效果。此外,格尔德霉素还能调节上皮氮氧合酶活性以及发挥抗炎作用;研究还表明,与化疗药物联用时,其表现出协同作用。

用途 格尔德霉素(GM,GDM)是潮湿链霉菌分泌的一种含有苯醌结构的化合物,属于苯醌安莎类抗生素。体外实验表明,GDM对多种肿瘤细胞的生长具有良好的抑制活性,并显示出广谱抗增殖和抗肿瘤的作用。

生物活性 Geldanamycin (NSC 122750) 是一种天然的HSP90抑制剂,其Kd值为1.2 μM。它特异性地干扰糖皮质激素受体(GR)/HSP的结合。此外,Geldanamycin通过减少宿主炎症反应来减轻病毒感染引起的急性肺损伤/急性呼吸窘迫综合征。

靶点

  • p185 (SKBr3 细胞):70 nM
  • HSP90 (N-末端结构域, 细胞外实验):0.78 μM (Kd)
  • HSP90 (细胞自由体系):1.2 μM (Kd)

体外研究 Geldanamycin结合于Hsp90s(残基1-220)N-末端结构域的ATP结合位点,并以剂量依赖性方式抑制Hsp90的ATPase活性。在A2780人卵巢细胞系中,Geldanamycin引起剂量依赖性的G2期阻滞,并可逆地抑制进入S期。该作用伴随着p53水平的增加,最终证明是p53依赖性的。此外,它导致p185受体蛋白-酪氨酸激酶的泛素化和蛋白酶体降解,其IC50值为70 nM。

体内研究 在FRE/erbB-2 小鼠模型中,Geldanamycin (50 mg/kg) 对 p185 相关的磷酸酪氨酸水平表现出30%的抑制作用。

用途 格尔德霉素广泛用于生化研究。

    名称:
    Synthesis and evaluation of poly(styrene-co-maleic acid) micellar nanocarriers for the delivery of tanespimycin
    摘要:
    Polymeric micelles carrying the heat shock protein 90 inhibitor tanespimycin (17-N-allylamino-17-demethoxygeldanamycin) were synthesized using poly(styrene-co-maleic acid) (SMA) copolymers and evaluated in vitro and in vivo. SMA-tanespimycin micelles were prepared with a loading efficiency of 93%. The micelles incorporated 25.6% tanespimycin by weight, exhibited a mean diameter of 74 +/- 7 nm by dynamic light scattering and a zeta potential of -35 +/- 3 mV. Tanespimycin was released from the micelles in a controlled manner in vitro, with 62% released in 24h from a pH 7.4 buffer containing bovine serum albumin. The micellar drug delivery systems for tanespimycin showed potent activity against DU145 human prostate cancer cells, with an IC(50) of 230 nM. They further exhibited potent anti-cancer activity in vivo in nu/nu mice bearing subcutaneous DU145 human prostate cancer tumor xenografts, with significantly higher anticancer efficacy as measured by tumor regression when compared to free tanespimycin at an equivalent single dose of 10 mg/kg. These data suggest further investigation of SMA-tanespimycin as a promising agent in the treatment of prostate cancer. (C) 2011 Elsevier B.V. All rights reserved.
