    名称:
    Synthesis of deuterium labeled NMDA receptor inhibitor – 20-Oxo-5β-[9,12,12-2H3]pregnan-3α-yl-l-glutamyl 1-ester
    摘要:
    20-Oxo-5 beta-[9,12,12-H-2(3)]pregnan-3 alpha-yl-L-glutamyl 1-ester 11 was synthesized as an internal standard for quantification of a neuroprotective NMDA receptor ligand, 20-oxo-5 beta-pregnan-3 alpha-yl-L-glutamyl 1-ester 18 and its metabolites, in plasma and tissue. 11 alpha-Hydroxy-progesterone (1) was reduced under basic conditions to yield the corresponding 5 beta-steroid. Protection of the 3- and 20-oxo groups and oxidation of the 11 alpha-hydroxy group was then followed by a deuterium exchange, conducted under basic conditions using deuterated methanol. Next, the carbonyl moiety at C-11 was reduced and the 11 alpha-hydroxyl group removed through utilization of the Barton-McCombie reaction. Subsequent deprotection of the 3- and 20-acetals and stereoselective reduction of the 3-oxo group gave the desired trideuterated pregnanolone (8). This was coupled with protected glutamic acid, which was then deprotected to yield [9,12,12-H-2(3)]-pregnanolone glutamate (11) with >99% isotopic purity. (C) 2011 Elsevier Inc. All rights reserved.

    -one), the principal neurosteroid acting via γ-aminobutyric acid (GABA). These analogues were designed to study the structural requirements of the corresponding GABAA receptor. Their biological activity was measured by in vitro test with [3H]flunitrazepam as radioligand in which allopregnanolone and its active analogues stimulated the binding to the GABAA receptor. Analysis of the SAR data suggests
