further enhances potency of the 1,3-dipropyl-8-phenylxanthine at both A1 and A2 receptors. The 8-(2-amino-4-chlorophenyl)-1,3-dipropylxanthine is a very potent and selective antagonist for A1 receptors, being nearly 400-fold more potent at A1 than at A2 receptors. The water-soluble 8-(p-sulfophenyl)- and 8-(p-carboxyphenyl)-1,3-propylxanthines no longer exhibit marked selectivity. Both compounds are
The present disclosure provides certain tetrazole derivatives that are inhibitors of transient receptor potential ankyrin 1 (TRPA1), and are therefore useful for the treatment of diseases treatable by inhibition of TRPA1. Also provided are pharmaceutical compositions containing the same, and processes for preparing said compounds.
Some 1-alkyl-3-aroylureas and a few related types have been synthesised for examination as anticonvulsants. Maximum activity was found in 3-benzoyl-1-n-butylurea and 1-n-butyl-3-o-toluoylurea
