The invention provides bupropion analogue compounds capable of inhibiting the reuptake of one or more monoamines. The compounds may selectively bind to one or more monoamine transporters, including those for dopamine, norepinephrine, and serotonin. Such compounds may be used to treat conditions that are responsive to inhibition of the reuptake of monoamines, including addiction, depression, and obesity.

α-Hydroxy-α-phenylamides are a newclass of small molecules that have demonstrated potent inhibition of voltage-gated sodium channels. The hydroxyamide motif, an isostere of a hydantoin ring, provides an active scaffold from which several potent racemic sodium channel blockers have been derived. With little known about chiral preferences, the development of chiral syntheses to obtain each pure enantiomer
已知电压门控钠通道在神经元和其他可兴奋细胞中表达。最近,已发现电压门控钠通道在人类前列腺癌细胞中表达。α-羟基-α-苯基酰胺是一类新的小分子,已证明能有效抑制电压门控钠通道。羟基酰胺基序是乙内酰脲环的等排体,提供了一种活性支架,从中衍生出几种有效的外消旋钠通道阻滞剂。由于对手性偏好知之甚少,开发手性合成以获得每种纯对映异构体作为钠通道阻滞剂进行评估很重要。使用 Seebach 和 Frater 的手性模板,( R )-3-氯扁桃酸与新戊醛的环缩合得到顺式- 和反式-2,5-二取代二氧戊环酮。使用该手性模板,我们合成了 2-(3-氯苯基)-2-羟基壬酰胺的两种对映异构体,并评估了它们在功能上抑制 hNa v亚型、人类前列腺癌细胞和异种移植物的能力。铅的对映异构体显示出显着降低体内前列腺癌的能力。

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.
