Abstract
Abstract The preparation of 1,5-bis-substituted-1,4-pentadien-3-one, substituted amidinohydrazone salts are described. They are prepared by the reaction of a 1,5-bis(substituted)-1,4pentadiene-3-one with a substituted aminoguanidine salt. These compounds are useful as anti-malarial and anti-tubercular agents in warm-blooded animals.
