calcium assay. The versatile applicability of the probes as tool compounds was demonstrated by flow cytometry- and fluorescence anisotropy-based Y1R binding studies (saturation and competition binding and association and dissociation kinetics) as well as by widefield and total internal reflection fluorescence (TIRF) microscopy of live tumor cells, revealing that fluorescence was mainly localized at the
神经肽 YY 1受体 (Y 1 R) 与精氨酰胺型 Y 1 R 选择性拮抗剂 UR-MK299 ( 2 ) 复合的最近结晶开辟了基于结构设计非肽 Y 1 R 配体的新方法。我们设计的新型荧光探针显示出优异的 Y 1 R 选择性,并且与先前描述的荧光 Y 1 R 配体相比,具有更高(~100 倍)的结合亲和力。这是通过将不同的荧光染料通过胺官能化接头连接到2中的二苯乙酰部分来实现的。荧光配体表现出皮摩尔Y 1R 结合亲和力(p K i值为 9.36-9.95)并被证明是 Y 1 R 拮抗剂,如在 Fura-2 钙测定中验证的那样。通过流式细胞仪和基于荧光各向异性的 Y 1 R 结合研究(饱和和竞争结合以及缔合和解离动力学)以及宽场和全内反射荧光 (TIRF) 显微镜证明了探针作为工具化合物的多功能适用性活肿瘤细胞,揭示荧光主要定位于质膜。

An efficient method for the preparation of protected phosphate ester-linked resins in high yield and purity is presented. Variation in tether length/functionality and substitution pattern of the phenol precursors, as well as mild deprotection conditions make this system ideal for the combinatorial generation of phenyl phosphate SH2 inhibitor libraries.

Photochromic pyrans for applications in material and life sciences were synthesized via palladium-mediated cyanation, carbonylation and Sonogashira cross-coupling starting from bromo-substituted naphthopyran 1 and benzopyrans 2a/b. A novel photoswitchable benzopyran-based omega-amino acid 6 for Fmoc-based solid-phase peptide synthesis is presented. The photochromic behaviour of the 3-cyano-substituted benzopyran
