3-Epideacetycinobufagin (EDCB) was found to be a highly isoform-specific probe substrate for 3-glucuronidation mediated by UDP-glucuronosyltransferase 2B7 (UGT2B7). The probe reaction was well-characterized, and our results strongly suggest that EDCB can be used specially to measure the catalytic activity of UGT2B7 in biological samples.
