TRPA1 channels: Novel targets of 1,4-dihydropyridines

open access: yes, 2012
Transient receptor potential type A1 (TRPA1) channels are cation permeable channels activated by irritant chemicals and pungent natural compounds. Their location in peptidergic sensory terminals innervating the skin and blood vessels makes them important

Novel bipodal, tripodal, and tetrapodal 1,4-dihydropyridines — Microwave-assisted synthesis and structural confinements

open access: yes, 2011
The one pot, three component reaction of p-hydroxy benzaldehyde, β-ketoester, and ammonium acetate afforded the corresponding monopodal 1,4-dihydropyridines as building blocks, which in turn converted into diversified novel bipodal, tripodal, and ...
