, p. 5363 - 5370 (2007/10/03)
Series of 1-alkyl histidines and histamines have been synthesized by the alkylation of the corresponding 5,6,7,8-tetrahydro-5-oxomidazo[1,5-c]pyrimidines with alkyl halides in aprotic solvents. The method of conversion of the intermediate quaternary salt to the amino acid or amino depends on the nature of the alkyl group.
CYCLIC CARBAMATE ANALOGUES OF (+)-PILOCARPINE
-
, (2008/06/13)
Pilocarpine analogues are provided having the structure STR1 where one of R 1 or R 2 is an alkyl, such as methyl, ethyl, propyl, butyl, and so forth, and the corresponding secondary alkyl groups, an aralkyl, such as benzyl, phenylethyl, phenylpropyl, and the corresponding secondary aralkyl residues, or a cycloalkyl having less than about 12 carbon atoms. R 3 has at least two carbon atoms but less than about 9. These pilocarpine analogues have improved duration of biological activity with respect to pilocarpine. A particularly preferred compound is a muscarinic agonist equipotent with pilocarpine, where R 2 is methyl, and R 3 is ethyl.
