The present invention relates to compounds and their use in competitive protein binding assays, for example for use with glycosyl transferase and/or glycoprocessing proteins. The present application also provides kits and apparatuses for use in the assays. In particular, the present invention provides a compound of the formula (I): wherein n is 1, 2 or 3; R1 is selected from —OH, —OPO3H, —OR4, —NHR4, R6; R2 and R3 are each independently selected from —H, —OH, optionally substituted —O-alkyl and —O-alkanoyl; R4 is selected from an optionally substituted mono or polysaccharide, -alkyl, -alkenyl, -alkynyl, and L-Z, where L is a linking agent and Z is a binding agent; R6 is an optionally substituted hydrocarbon group; A is either (i) a substituted heteroaryl group, the substituent on the heteroaryl group having a double bond conjugated to the heteroaryl group, or (ii) a substituted aryl group, the substituent on the aryl group having a double bond conjugated to the aryl group.
本发明涉及化合物及其在竞争性蛋白质结合测定中的应用,例如用于糖基转移酶和/或糖基加工蛋白质的应用。本申请还提供用于该测定的试剂盒和设备。具体而言,本发明提供了式(I)的化合物:其中n为1、2或3;R1选自—OH、—OPO3H、—OR4、—NHR4、R6;R2和R3各自独立地选自—H、—OH、可选地取代的—O-烷基和—O-酰基烷基;R4选自可选地取代的单糖或多糖、-烷基、-烯基、-炔基和L-Z,其中L是连接剂,Z是结合剂;R6是可选地取代的碳氢基团;A是(i)取代的杂芳基团,杂芳基团上的取代基具有与杂芳基团共轭的双键,或(ii)取代的芳基团,芳基团上的取代基具有与芳基团共轭的双键。
