    摘要:
    AbstractBackground and PurposeNeurosteroids are allosteric modulators of GABAA currents, acting through several functional binding sites although their affinity and specificity for each site are unknown. The goal of this study was to measure steady‐state binding affinities of various neurosteroids for specific sites on the GABAA receptor.Experimental ApproachTwo methods were developed to measure neurosteroid binding affinity: (1) quenching of specific tryptophan residues in neurosteroid binding sites by the neurosteroid 17‐methylketone group, and (2) FRET between MQ290 (an intrinsically fluorescent neurosteroid) and tryptophan residues in the binding sites. The assays were developed using ELIC‐α1GABAAR, a chimeric receptor containing transmembrane domains of the α1‐GABAA receptor. Tryptophan mutagenesis was used to identify specific interactions.Key ResultsAllopregnanolone (3α‐OH neurosteroid) was shown to bind at intersubunit and intrasubunit sites with equal affinity, whereas epi‐allopregnanolone (3β‐OH neurosteroid) binds at the intrasubunit site. MQ290 formed a strong FRET pair with W246, acting as a site‐specific probe for the intersubunit site. The affinity and site‐specificity of several neurosteroid agonists and inverse agonists was measured using the MQ290 binding assay. The FRET assay distinguishes between competitive and allosteric inhibition of MQ290 binding and demonstrated an allosteric interaction between the two neurosteroid binding sites.Conclusions and ImplicationsThe affinity and specificity of neurosteroid binding to two sites in the ELIC‐α1GABAAR were directly measured and an allosteric interaction between the sites was revealed. Adaptation of the MQ290 FRET assay to a plate‐reader format will enable screening for high affinity agonists and antagonists for neurosteroid binding sites.

    diastereoselective Michael/aldol cascade approach is used to accomplish concise total syntheses of cardiotonic steroids with varying degrees of oxygenation including cardenolides ouabagenin, sarmentologenin, 19-hydroxysarmentogenin, and 5- epi-panogenin. These syntheses enabled the subsequent structure activity relationship (SAR) studies on 37 synthetic and natural steroids to elucidate the effect of oxygenation
