    摘要:
    This paper reports the synthesis and binding assays toward benzodiazepine and adenosine A(1) and A(2A) receptors of new 1,2,3-triazolo[1,5-a]quinoxalin-4-one derivatives. The prepared compounds show good affinity toward the benzodiazepine receptor (K-i 53-314 nM); the GABA ratio values suggest an inverse agonist activity for the N(5) unsubstituted compounds 6b-d and an agonist activity for the N(5) methylated compounds 7a-c. Some derivatives of both series show good affinity (Ki < 100 nM) and selectivity toward the adenosine A(1) receptorial subtype. (C) Elsevier, Paris.

  • THE CONVERSION OF α-KETO ACIDS AND OF α-KETO ACID OXIMES TO NITRILES IN AQUEOUS SOLUTION
    作者:A. Ahmad、Ian D. Spenser
    DOI:10.1139/v61-169
    日期:1961.6.1

    The conversion of α-oximino acids (anti HO— —COOH) to nitriles in aqueous solution is shown to be a general reaction. α-Keto acids are converted to nitriles in excellent yield in aqueous solution in the presence of hydroxylamine. Oxidation of α-oximino acids yields hydroxamic acids.

    溶液中,α-羟酸(抗HO— —COOH)转化为腈是一种普遍的反应。在溶液中,α-酮酸羟胺存在下以极高的产率转化为腈。α-羟酸的氧化产生羟胺酸。
