ABSTRACT:
Compounds of the formula (1) ##STR1## wherein X and Y are each N or NH, Z is O or OH, (1) when X=N and Y=NH, Z=O, and *1 and *3 are double bonds, (2) when X=NH and Y=N, Z=O, and *2 and *3 are double bonds, (3) when X=N and Y=N, Z=OH, and *2 and *4 are double bonds, and R is a side chain derived from an amino acid; for example, the amino acid is glycine with R=H, alanine with R=CH.sub.3, glutamic acid with R=CH.sub.2 CH.sub.2 COOH, lysine with R=CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.2 NH.sub.2, or leucine with R=CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.3, and/or an analogues thereof are useful for imparting a "thick, sour" taste to foods.
