  Synthesis and in Vitro Activity of 3β-Substituted-3α-hydroxypregnan-20-ones:  Allosteric Modulators of the GABA_A Receptor

  摘要：

  Two naturally occurring metabolites of progesterone, 3 alpha-hydroxy-5 alpha- and 5 beta-pregnan-20-one (1 and 2), are potent allosteric modulators of the GABA(A) receptor. Their therapeutic potential as anxiolytics, anticonvulsants, and sedative/hypnotics is limited by rapid metabolism. To avoid these shortcomings, a series of 3 beta-substituted derivatives of 1 and 2 was prepared. Small lipophilic groups generally maintain potency in both the 5 alpha- and 5 beta-series as determined by inhibition of [S-35]TBPS binding. In the 5 alpha-series, 3 beta-ethyl, -propyl, -trifluoromethyl and -(benzyloxy)methyl, as well as substituents of the form 3 beta-XCH(2), where X is Cl, Br, or I or contains unsaturation, show limited efficacy in inhibiting [S-35]TBPS binding. In the 5 beta-series, the unsubstituted parent 2 is a two-component inhibitor, whereas all of the 3 beta-substituted derivatives of 2 inhibit TBPS via a single class of binding sites. In addition, all of the 3-substituted 5 beta-sterols tested are full inhibitors of [S-35]TBPS binding. Electrophysiological measurements using alpha 1 beta 2 gamma 2L receptors expressed in oocytes show that 3 beta-methyl- and 3 beta-(azidomethyl)-3 alpha-hydroxy-5 alpha-pregnan-20-one (6 and 22, respectively) are potent full efficacy modulators and that 3 alpha-hydroxy-3 beta-(trifluoromethyl)-5 alpha-pregnan-20-one (24) is a low-efficacy modulator, confirming the results obtained from [S-35]TBPS binding. These results indicate that modification of the 3 beta-position in 1 and 2 maintains activity at the neuroactive steroid site on the GABA(A) receptor. In animal studies, compound 6 (CCD 1042) is an orally active anticonvulsant, while the naturally occurring progesterone metabolites I and 2 are inactive when administered orally, suggesting that 3 beta-substitution slows metabolism of the S-hydroxyl, resulting in orally bioavailable steroid modulators of the GABA(A) receptor.

  Neuroactive steroids that allosterically modulate GABAA receptors have potential uses as anticonvulsants, anxiolytics, and sedative-hypnotic agents. Recently, a series of pregnanes substituted with simple alkyl groups at the 3 beta-position were synthesized and found to be active in vitro. The present report describes the synthesis of a series of substituted 3 alpha-hydroxy-3 beta-(phenylethynyl)pregnan-20-ones

  变构调节GABAA受体的神经活性类固醇有潜在用途，可作为抗惊厥药，抗焦虑药和镇静催眠药。最近，合成了一系列在3β位置被简单烷基取代的孕烷，并发现其在体外具有活性。本报告描述了一系列取代的3α-羟基-3β-（苯基乙炔基）pregnan-20-的合成及其通过体外抑制大鼠脑中[35S] TBPS结合力确定的体外结构-活性关系。膜。适当取代苯基会导致配体对GABAA受体上的神经活性类固醇位点具有特别高的亲和力（例如4-乙酰基28，IC50 10 nM）。在表达克隆的人GABAAα1β2γ2L受体（例如化合物28，EC50 6.6 nM）的卵母细胞中，通过电生理学证实了所选类固醇的效力。与它们的体外活性一致，在小鼠腹腔注射后，一些3β-（苯乙炔基）取代的类固醇在戊四氮（PTZ）和最大电击（MES）试验中显示出抗惊厥活性。值得注意的是，3β-[（（4-乙酰基苯基）乙炔基] -19-nor衍生物36表现出有吸引力的抗惊厥特征（PTZ和MES
