Aglycone-focused randomization of 2-difluoromethylphenyl-type sialoside suicide substrates for neuraminidases
چکیده انگلیسی
A selective and potent inhibitor of neuraminidases, a hydrolase that is responsible for processing sialylated glycoconjugates, is a promising drug candidate for various infective diseases. The current study demonstrates that the use of an aglycone-focused library of 2-difluoromethylphenyl α-sialosides is an effective technique to find potent and selective mechanism-based labeling reagents for neuraminidases. The focused library was constructed from a 4-azide-2-difluoromethylphenyl sialoside (2) and an alkyne-terminated compound library by a click reaction. The focused library showed different inhibition patterns for two neuraminidases, Vibrio cholerae neuraminidase (VCNA) and human neuraminidase 2 (hNeu2), and the most potent inhibitors for each neuraminidase were selected. A kinetic analysis of the selected inhibitors demonstrated that the modification of the aglycone moiety improved the KI value with little change in the t1/2 value of the enzyme activity relative to the basic skeleton (2).
