  Novel 3,6,7-Substituted Pyrazolopyrimidines as Positive Allosteric Modulators for the Hydroxycarboxylic Acid Receptor 2 (GPR109A)

  摘要：

  A number of pyrazolopyrimidines were synthesized and tested for their positive allosteric modulation of the HCA(2) receptor (GPR109A). Compound 24, an efficacious and potent agonist and allosteric enhancer of nicotinic acid's action, was the basis for most other compounds. Interestingly, some of the compounds were found to increase the efficacy of the endogenous ligand 3-hydroxybutyrate and enhance its potency almost 10-fold. This suggests that the pyrazolopyrimidines may have therapeutic value when given alone.

  Pyrazolopyrimidines were discovered as the first class of allosteric agonists for the high affinity nicotinic acid receptor GPR109A. In addition to its intrinsic activity, compound 9n significantly enhances nicotinic acid binding to the receptor, thereby potentiating the functional efficacy of nicotinic acid.

  发现吡唑并嘧啶是高亲和力烟酸受体GPR109A的第一类变构激动剂。除了其固有活性外，化合物9n还显着增强了烟酸与受体的结合，从而增强了烟酸的功能功效。
