Four pyrrolo[1,2-d][1,2,4]triazines and four thiazolo[3,4- d][1,2,4]triazines were synthesized from trans-4-hydroxy-L-proline and L- thiaproline, respectively. The synthetic route involved formation of hydrazides followed by cyclization with orthoesters. The proliferative response to human lymphocyte mitogen (phytohemagglutinin) revealed significant immunostimulant activity for all test drugs. Furthermore, some triazine derivatives were effective to activate production of free oxygen radical by phagocytes in response to stimulation by opsonized zymosan.
DERIVATIVES OF HETEROCYCLIC α-IMINOCARBOXYLIC ACIDS. 1. SYNTHESES OF HYDRAZIDES OF HETEROCYCLIC α-IMINOCARBOXYLIC ACIDS AND THEIR HYDRAZONES

By the interaction of esters of L-proline, L-thioproline, pipecolic acid, and tetrahydro-1,4-thiazine-3-carboxylic acid with hydrazine, the corresponding hydrazides were obtained, which react with equimolar quantities of carbonyl compounds to form hydrazo
