The synthesis of a series of 12 compounds referring to 4-anilino-2-methylthiopyrido [2,3-d]pyrimidines (1-12), and the results of a study of their diuretic, saliuretic and antihypertensive activities are reported. Most of this compounds showed significant diuretic activity at the dosage of 3-24 mg/kg. The 4-Anilino-2-methylthiopirido[2,3-d]pyrimidine 1 remained active to a dosage of 1 mg/kg. The diuretic activity of these compounds implied an increase in the Na+ excretion. Some of the most active diuretics have been studied for antihypertensive effect.
