制备方法与用途

生物活性

Brevetoxin-3(PbTx-3)是一种有效的变构电压门控Na+通道激活剂,具有多个活性中心(A环内酯,R侧链的C-42)。它对电压敏感的Na+通道的位点5具有高亲和力,能够抑制这些通道的失活并延长它们的平均打开时间。Brevetoxin-3会导致气道高反应性延长和肺部炎症。

靶点

IC50: 电压门控Na⁺通道

体外研究

在稳态条件下(维持去极化-50 mV),Brevetoxin-3(PbTx-3)(浓度为30-500 nM)会产生膜电位负移的激活偏移,使得单通道活动变得可见。

体内研究

通过气管给药(2.8 μg/kg;妊娠第15-18天),Brevetoxin-3在妊娠第1小时内在胎盘和胎儿中可检测到放射性。在整个48小时的用药后,胎儿中的海伦诺毒素等效浓度约为0.3 ng/g,计算得出对胎儿的剂量为19 ng/h。给药后的海伦诺毒素等效浓度在胎儿中降低至0.1 ng/g,低于大多数母体组织中的浓度。

动物模型:怀孕的CD-1小鼠
剂量:2.8 μg/kg
给药方式:气管给药;妊娠第15-18天
结果:证实了海伦诺毒素或其代谢物在母体急性暴露后的胎盘转运。

  • Brevetoxin B: Chemical Modifications, Synaptosome Binding, Toxicity, and an Unexpected Conformational Effect
    作者:Kathleen S. Rein、Bert Lynn、Robert E. Gawley、Daniel G. Baden
    DOI:10.1021/jo00087a028
    日期:1994.4
    Five naturally occurring brevetoxins and seven synthetically modified brevetoxins were examined for their affinity for site 5 of the voltage-gated sodium channel and their toxicity to mosquito fish, Gambusia affinis. All but three of the toxins studied still retained some affinity for their receptor site (IC50's in the range of 1-100 nM). Compound 7, having all three carbon-carbon double bonds reduced, is almost 3 orders of magnitude less strongly bound than 4, which has only two carbon-carbon bonds reduced. This large effect resulting from H-ring reduction was unexpected, due to the similarity of this region of the molecule to the corresponding region of brevetoxin-A, which has a fully saturated eight-membered G-ring and is the most strongly bound toxin of those studied. Conformational analysis revealed that the unsaturated H-ring of brevetoxin B favors the boat-chair conformation as does the saturated G-ring of brevetoxin A. Upon reduction, the H-ring of brevetoxin B shifts to a crown conformation. This subtle change in conformational preference induces a significant change in the gross shape of the molecule, which we believe is responsible for the loss of binding affinity and toxicity.
