  Syntheses of (+)-Complanadine A and Lycodine Derivatives by Regioselective [2 + 2 + 2] Cycloadditions

  摘要：

  The dimeric alkaloid complanadine A has shown promise in regenerative science, promoting neuronal growth by inducing the secretion of growth factors from glial cells. Through the use of tandem, cobalt-mediated [2 + 2 + 2] cycloaddition reactions, two synthetic routes have been developed with different sequences for the formation of the unsymmetric bipyridyl core. The regioselective formation of each of the pyridines was achieved based on the inherent selectivity of the molecules or by reversing the regioselectivity through the addition of Lewis bases. This strategy has been successfully employed to provide laboratory access to complanadine A as well as structurally related compounds possessing the lycocline core.

• Complanadine A, a selective agonist for the Mas-related G protein-coupled receptor X2
  作者：Trevor Johnson、Dionicio Siegel

  DOI：10.1016/j.bmcl.2014.05.060

  日期：2014.8

  The first biological target for the natural product complanadine A has been determined. The pseudosymmetric alkaloid functions as a selective agonist for the Mas-related G protein-coupled receptor X2 (MrgprX2), a G protein-coupled receptor that is highly expressed in neurons. Given the potential of MrgprX2 to function as a modulator of pain, complanadine A represents a new chemical probe to selectively interrogate the physiological function of MrgprX2 as well as a potential lead for the development of antihyperalgesics for the treatment of persistent pain. While complanadine A possess agonistic activity the related natural product lycodine, representing half of complanadine A, lacks activity providing a cursory description of the structural requirements for agonistic activity.
