Abstract
Novel substrates for monitoring of catalytic activity resulting in hydrolytic release of products which can be readily detected by spectrophotometric or fluorometric means are provided. The substrates have the general formula: ##STR1## wherein B is a nucleotide base capable of assisting in hydrolysis of the phosphate ester at the 3'-position; R is a moiety selected from the group consisting of umbelliferonyl, 4-methylumbelliferonyl, 3-flavonyl, o-nitrophenyl, m-nitrophenyl, p-nitrophenyl, dinitrophenyl, cyanophenyl, acylphenyl, carboxyphenyl, phenylsulfonate, phenylsulfonyl and phenylsulfoxide; R' is a moiety selected from the group consisting of hydrogen, alkyl, alkenyl cycloalkyl, aryl, araalkyl, acyl, oxaalkyl, thioalkyl, oxacycloalkyl, and thiocycloalkyl and R" is hydrogen or a cation selected from the group consisting of calcium, barium, lithium, sodium, ammonium, substituted ammonium and pyridinium. The substrates are capable of undergoing catalytic-induced hydrolysis of the phosphate ester at the 3'-position to yield a species capable of being monitored spectrophotometrically or fluorometrically.
