The fluorescence emission of warfarin is further increased upon the addition of the diterpenes in the low concentration range. This happens with both 16-O-methylcafestol and cafestol, despite the fact that their different effect on albumin tryptophan emission suggests a different mode of binding. This behavior as displace warfarin by competition in the binding site, rather than enhancing the affinity.
