Thirty-one 1,3,7,8-substituted xanthine derivatives have been synthesized and evaluated for bronchodilator and anti-bronchoconstrictory activities in in vitro tracheal relaxation and in vivo bronchospasm inhibition models. Activity tests have been complemented with phosphodiesterase inhibition and toxicological data. Structure-activity relationships are discussed. Compound 21 (1,3-diisobutyl-8-methylxanthine) has been selected for further pharmacological development because of its good activity profile and favourable therapeutic index, which is 14- and 38-fold greater than that of theophylline and IBMX, respectively.
