Disclosed are molecules and their synthesis, for use in blocking gated ion channels such as voltage-gated sodium channels (VGSCs) and prostate voltage sodium channels (PVSCs). These inhibitors have superior blocking efficacy, for instance in displacing the radioligand [
3
H]-Batrachotoxin-B ([
3
H]-BTX-B) that binds to site 2 of a VGSC. The molecules of the invention comprise a moiety which increases the binding affinity of molecules for the protein binding site in prostate cancer cells (PCs), and which is also fluorescent. In one embodiment the invention molecules are an inhibition system that can be used to target over-abundant or hyperactive VGSCs selectively in pain, epilepsy or prostate cancer, inhibiting the proliferation of PCs. The fluorescent moiety also facilitates screening, tracking, and pharmacodynamic studies of the drug in a biological system both in vitro and in vivo.
本发明涉及分子及其合成,用于阻断门控离子通道,例如电压门控钠通道(VGSC)和前列腺电压钠通道(PVSC)。这些抑制剂具有卓越的阻断效力,例如在取代结合到VGSC的位点2的放射性配体[3H]-Batrachotoxin-B ([3H]-BTX-B)方面。本发明的分子包括一个基团,增加分子对前列腺癌细胞(PC)中蛋白质结合位点的结合亲和力,并且也是荧光的。在一种实施方式中,本发明的分子是一种抑制系统,可用于选择性地靶向过度丰富或过度活跃的VGSC,从而抑制疼痛、癫痫或前列腺癌的PC的增殖。荧光基团还有助于在体外和体内生物系统中筛选、跟踪和药效学研究药物。
