• Structure–activity relationships of 1,4-dihydropyridines that act as enhancers of the vanilloid receptor 1 (TRPV1)

  Vanilloid agonists such as capsaicin activate ion flux through the TRPV1 channel, a heat- and ligand-gated cation channel that transduces painful chemical or thermal stimuli applied to peripheral nerve endings in skin or deep tissues. We have probed the SAR of a variety of 1,4-dihydropyridine (DHP) derivatives as novel 'enhancers' of TRPV1 activity by examining changes in capsaicin-induced elevations in Ca-45(2+)-uptake in either cells ectopically expressing TRPV1 or in cultured dorsal root ganglion (DRG) neurons. The enhancers increased the maximal capsaicin effect on Ca-45(2+)-uptake by typically 2- to 3-fold without producing an action when used alone. The DHP enhancers contained 6-aryl substitution and small alkyl groups at the 1 and 4 positions, and a 3-phenylalkylthioester was tolerated. Levels of free intracellular Ca2+, as measured by calcium imaging, were also increased in DRG neurons when exposed to the combination of capsaicin and the most efficacious enhancer 23 compared to capsaicin alone. Thus, DHPs can modulate TRPV1 channels in a positive fashion. Published by Elsevier Ltd.

  The present invention provides certain novel pyridine and dihydropyridine derivatives, pharmaceutical compositions comprising one or more of these derivatives, and a method of treating a mammal by selectively blocking an A3 adenosine receptor of the mammal by the administration of a pyridine or dihydropyridine derivative of the present invention. Thus, for example, the present invention provides the following pyridine derivatives of formula (I) or a pharmaceutically acceptable salt thereof; wherein R2 is selected from the group consisting of C1-C6 alkyl, C3-C7 cycloalkyl, and C1-C6 alkoxy C1-C6 alkyl; R3 is selected from the group consisting of C1-C6 alkoxy, C1-C6 alkylsulfanyl, hydroxy, C1-C6 alkoxy C1-C6 alkylsulfanyl, hydroxy C1-C6 alkylsulfanyl, and halo C1-C6 alkylsulfanyl, or R3 together with R4 forms a 3-7 membered heterocyclic ring containing O, N, or S; R4 is selected from the group consisting of C1-C6 alkyl, halo C1-C6 alkyl, hydroxy C1-C6 alkyl, C1-C6 alkoxy, C1-C6 alkylsulfanyl, C1-C6 alkylamino, C1-C6 alkylcarbonyl sulfanyl C1-C6 alkyl, aryl C2-C6 alkenyl, aryl C2-C6 alkynyl, formyl, and acetal; R5 is selected from the group consisting of C1-C6 alkyl, aryl C1-C6 alkyl, hydroxy C1-C6 alkyl, and halo C1-C6 alkyl; and R6 is selected from the group consisting of aryl, C3-C7 cycloalkyl, and haloaryl; wherein said aryl is a phenyl or naphthyl. The compounds of the present invention can be used for inhibiting the binding of ligands to an adenosine receptor of a substrate. The compounds of the present invention can be used for characterizing an adenosine receptor in a substrate.
