building blocks (key components in clickchemistry). We report herein a highly robust and efficient strategy for high-throughput synthesis of a 325-member azide library. The method is highlighted by its simplicity and product purity. The utility of the library is demonstrated with the subsequent “click” synthesis of the corresponding bidentate inhibitors against PTP1B.

Through the simultaneous use of three orthogonal dynamiccovalent reactions, namely disulfide, boronate, and acyl hydrazone formation, we conceived a facile and versatile protocol to spatially organize tailored chromophores, which absorb in the blue, red, and yellow regions, on a preprogrammed α‐helix peptide. This approach allowed the assembly of the dyes in the desired ratio and spacing, as dictated
Clickchemistry allows the facile synthesis of selective G-quadruplex ligands. The synthesized compounds were tested against a telomeric G-quadruplex structure using ESI-MS, fluorescence melting, circular dichroism and molecular docking.

The design, modeling, synthesis, biological evaluation of a novel series of photoreactive benzamide probes for class I HDAC isoforms is reported. The probes are potent and selective for HDAC1 and 2 and are efficient in crosslinking to HDAC2 as demonstrated by photolabeling experiments. The probes exhibit a time-dependent inhibition of class I HDACs. The inhibitory activities of the probes were influenced
报告了针对 I 类 HDAC 同种型的一系列新型光反应性苯甲酰胺探针的设计、建模、合成和生物学评估。这些探针对 HDAC1 和 2 是有效的和选择性的,并且如光标记实验所证明的那样,可以有效地与 HDAC2 交联。探针表现出对 I 类 HDAC 的时间依赖性抑制。探针的抑制活性受到光交联和生物素标签附着所必需的芳基和烷基叠氮基的定位的影响。探针抑制 MDA-MB-231 细胞系中 H4 的脱乙酰化,表明它们具有细胞渗透性并靶向核 HDAC。
