Abstract
NEW MATERIAL:Hydroxypyruvic aldehyde phenylosazone derivatives of the formula (R1 and R2 are H, lower alkyl, halogen, nitro; however, cases are excluded where both R1 and R2 are H, R1 is 4-bromo and R2 is H, or both R1 and R2 are nitro).
EXAMPLE: Hydroxypyruvic aldehyde p-tolylosazone.
USE: Medicines as anti-inflammatory agent, etc., having high activity stabilizing erythrocitic membranes.
PREPARATION: In an example, the reaction between glycerolaldehyde or diethydroxy-acetone and a substituted phenylhydrazine is carried out in water or an alcoholic solvent, when necessary, in the presence of an acid catalyst to prepare the objective compound of the formula.
