  Coumarin 1,4-Dihydropyridine Derivatives

  摘要：

  A series of 1,4-dihydropyridines bearing a coumarin moiety in 4-position was synthesized. The compounds were evaluated for inotropic, chronotropic and calcium antagonist activities. The replacement of the o-nitrophenyl moiety of nifedipine with a coumarin or phenylcoumarin system is accompained by a decrease of the activity on myocardial and vascular parameters, but the synthesized compounds showed selective inhibiting effects on cardiac contractility and frequency.

  A highly efficient and straightforward synthesis of diversely substituted coumarins from ynamides and salicylaldehydes in the presence of Zn(II) catalyst has been developed. The sulfonamide moiety of ynamides was successfully recycled in this process, serving as an effective traceless directing group for high regioselectivity in the bond-forming event. The advantages of this protocol are good functional

  Adenosine receptors participate in many physiological functions. Molecules that may selectively interact with one of the receptors are favorable multifunctional chemical entities to treat or decelerate the evolution of different diseases. 3-Arylcoumarins have already been studied as neuroprotective agents by our group. Here, differently 8-substituted 3-arylcoumarins are complementarily studied as ligands of adenosine receptors, performing radioligand binding assays. Among the synthesized compounds, selective A(3) receptor antagonists were found. 3-(4-Bromophenyl)-8-hydroxycoumarin (compound 4) displayed the highest potency and selectivity as A(3) receptor antagonist (K-i = 258 nM). An analysis of its X-ray diffraction provided detailed information on its structure. Further evaluation of a selected series of compounds indicated that it is the nature and position of the substituents that determine their activity and selectivity. Theoretical modeling calculations corroborate and explain the experimental data, suggesting this novel scaffold can be involved in the generation of candidates as multitarget drugs.
