title: Synthesis and preliminary pharmacological screening of some 8-substituted methylxanthines.
abstract: Methods of synthesis, chemical properties and results of preliminary pharmacological screening for 8-amino substituted derivatives of caffeine (1-3) and 7,8-disubstituted derivatives of 8-aminotheophylline (8-12) have been described. The compounds show weak sedative and antidepressive activity and some of them (2, 10, 12) also small antinociceptive effect.
