This paper describes the synthesis of 6-substituted imidazo[2,1-b] thiazoles with a lactam ring connected, by means of a methine group, to the 5-position. The pharmacological results show that interesting cardiotonic activity is obtained when the lactam ring is pseudothiohydantoin (8) or barbituric acid (9). Even the substituent at position 6 plays an important role in the pharmacological behavior of these derivatives. The following activity rank order was observed: phenyl > methyl > chlorine.
