Abstract:
N2‐alkyl and N2‐alkanoyl derivatives of guanosine 5′‐phosphate bearing a sulfoxide group into the side chain (3b,e; 4b)were synthesized and tested for their synergistic effect with monosodium‐L‐glutamate (MSG), which is the prototypical substance
imparting umami taste to savoury‐based foods. Capacities to enhance the taste intensity of MSG were estimated (as γ values)
through subjective comparisons of MSG/5′‐nucleotide mixtures in water with appropriate solutions of MSG alone, followed by statistical treatment (Probitmethod) of the resulting responses. The synergistic activity of each sulfoxide toward MSG resulted to be lower than that of the corresponding sulfide.
