Peptide sweeteners. 5. Side chain homologs relating zwitterionic and trifluoroacetylated amino acid anilide and dipeptide sweeteners
摘要:
Side-chain homologues of sweet trifluoroacetyl-alpha-L-aspartyl-p-cyanoanilide have been synthesized and tasted. Removal of the trifluoroacetyl group only changes the potency of sweet taste, not the taste property. These results have been compared with the structure-taste relationships of dipeptide sweeteners. An informative discontinuity of taste effects was found to exist with novel aminomalonyl dipeptide derivatives. The results are explained on topochemical grounds.

A series of analogues of trifluoroacetyl-alpha-L-aspartylanilides substituted at various positions on the aromatic ring was synthesized and tasted. The position of the substitution is essential for the nature of the taste response. The results clearly establish the close relationship between sweet and bitter taste for these compounds. Combined electronic and topochemical contributions are discussed.
