Described is a method for screening an encoded chemical library, which library comprises a plurality of different chemical structures each releasably linked to an encoding tag, the method comprising the steps of: (a) providing said library of tagged chemical structures; (b) releasing each chemical structure from its tag to produce a plurality of free, tagless chemical structures (TCSs); (c) screening the TCSs by contacting them with a assay system under conditions whereby a spatial association between each TCS and its tag is maintained, to produce a plurality of different screened TCSs each spatially associated with its tag; and (d) identifying a screened TCS by decoding a tag that is spatially associated therewith.

coupled to nicotinamide mononucleotide to form the NAD analog 8-N3-2ʹ-O-propargyl-NAD. This NAD analog was recognized by Aplysia californica ADP-ribosyl cyclase and enzymaticallycyclized producing 8-N3-2ʹ-O-propargyl cyclic ADP-ribose. Photo-clickable cyclic-ADP-ribose analog was envisioned as a probe to label cyclic ADP-ribose binding proteins. The monofunctional 8-N3-cADPR has previously been shown to
设计并合成了一种可光点击的腺苷类似物,其中光活性官能团(8-叠氮腺苷)和点击部分(2ʹ-O-炔丙基醚)在腺苷核苷本身的结构内紧密结合。我们以腺苷为原料,分四步合成了8-N 3 -2ʹ-O-炔丙基腺苷。这种可光点击的腺苷被 5′-磷酸化,并与烟酰胺单核苷酸偶联,形成 NAD 类似物 8-N 3 -2′-O-炔丙基-NAD。这种 NAD 类似物被海兔ADP-核糖基环化酶识别,并通过酶促环化产生 8-N 3 -2ʹ-O-炔丙基环状 ADP-核糖。可光点击的环状ADP核糖类似物被设想作为标记环状ADP核糖结合蛋白的探针。单功能 8-N 3 -cADPR 先前已被证明是 cADPR 诱导的钙释放的拮抗剂 [TF Walseth 等人。等人,J.Biol。化学 (1993) 268, 26686–26691]。 2ʹ-O-炔丙基-cADPR 被认为是一种激动剂,当以低浓度添加到海胆卵匀浆中时,会引发 Ca
