probe design. Among these threederivatives, the ApA–PPA–TAMRA probe specifically photoreacted with both actin and tubulin in vitro. However, the photolabeling yield of tubulin was quite low (up to ∼1%), and one of the major side-reactions was the addition of a water molecule to the carbene species generated from an aryldiazirine moiety on the hydrophilic surface of actin.

A novel heterotrifunctional peptide-based cross-linking reagent for facile access to bioconjugates. Applications to peptide fluorescent labelling and immobilisation
versatile and straightforward synthesis of a novel heterotrifunctional peptide-based linker molecule is described. This generic bio-labelling reagent contains an amine-reactive N-hydroxysuccinimidyl carbamate moiety, an aldehyde/ketone-reactive aminooxy group and a thiol group with a propensity to form urea, oxime and thioether linkages respectively. The full chemical orthogonality between the free
The antitumor and apoptogenic macrolide aplyronine A (ApA) is a potent actin-depolymerizing agent. We developed an ApA acetylene analog that bears the aryldiazirine group at the C34 terminus, which formed a covalent bond with actin. With the use of the photoaffinity biotinderivatives of aplyronines A and C, Arp2 and Arp3 (actin-related proteins) were specifically purified as binding proteins along
抗肿瘤和凋亡大环内酯 aplyronine A (ApA) 是一种有效的肌动蛋白解聚剂。我们开发了一种在 C34 末端带有芳基二氮丙啶基团的 ApA 乙炔类似物,它与肌动蛋白形成共价键。使用 aplyronines A 和 C 的光亲和生物素衍生物,Arp2 和 Arp3(肌动蛋白相关蛋白)与来自肿瘤细胞裂解物的肌动蛋白一起被特异性纯化为结合蛋白。然而,Arp2 和 Arp3 不与 aplyronine 光亲和衍生物共价结合。因此,肌动蛋白相关蛋白可能作为肌动蛋白/ApA 复合物的三元加合物或通过寡聚肌动蛋白间接结合到 ApA。
