Discovery of Potent, Orally Available Vanilloid Receptor-1 Antagonists. Structure−Activity Relationship of N-Aryl Cinnamides
摘要:
The vanilloid receptor-1 (TRPV1 or VR1) is a member of the transient receptor potential (TRP) family of ion channels and plays a role in regulating the function of sensory nerves. A growing body of evidence demonstrates the therapeutic potential of TRPV1 modulators: particularly in the management of pain. As a result of our screening efforts, we identified (E)-3-(4-tert-butylphenyl)-N-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)acrylamide (1): an antagonist that blocks the capsaicin-induced and pH-induced uptake of Ca-45(2+) in TRPV1-expressing Chinese hamster ovary cells with IC50 values of 17 +/- 5 and 150 +/- 80 nM, respectively. In this report.. we describe the synthesis and structure-activity relationship of a series of N-aryl cinnamides, the most potent of which (49a and 49b) exhibit good oral bioavailability in rats (F-oral = 39% and 17%. respectively).

this paper, we have developed photocatalyst-free and visible light-driven decarboxylative alkylation of pyridinaldehydes. The photochemical reactions are initiated via photoinduced single electron transfer from triethylamine to N-hydroxyphthalimide esters in electrondonor–acceptorcomplexes. This photochemical method can achieve to translate 15 pyridinaldehydes and 11 2-quinolinaldehydes to the corresponding
A new ringcontraction reaction giving pyridine derivatives from 3,6- and 2,5-di-tert-butyl-3H-azepines was observed by a successive treatment with bromine and aqueous K2CO3. A plausible mechanism via azatropilium cation for the rearrangement was discussed based on the product’s distribution from respective 3H-azepines.

carbene iridium complex featuring metal-centered chirality was designed and applied to the asymmetric transfer hydrogenation (ATH) of imines. Four strongly σ-donating carbon-based substituents (2 carbenes and 2 phenyl moieties), a chirality transfer directly from the stereogenic metal center to the C=N bond of substrates, as well as a restriction of catalyst deactivation by steric demanding substituents
