    Abstract:
    A series of 5-amino-3-methylisoxazole[5,4-d]4-pyrimidinone derivatives were obtained by reacting substituted 5-amino-3-methylisoxazol-4-carboxylic acid hydrazide with ethyl ortho-formate. The compounds were tested using the models of in vivo cellular and humoral immune response in mice and pokeweed mitogen-induced (PWM-induced) polyclonal antibody production in a culture of human peripheral blood mononuclear cells (PBMC). The compounds exhibited differential inhibitory activities in the described models, depending on the character and location of the substituted groups. We suggest that the compounds affect the early stages of the immune response.
