chimeras (PROTACs) are bispecific molecules containing a target protein binder and an ubiquitin ligase binder connected by a linker. By recruiting an ubiquitin ligase to a target protein, PROTACs promote ubiquitination and proteasomal degradation of the target protein. The generation of effective PROTACs depends on the nature of the protein/ligase ligand pair, linkage site, linker length, and linker composition

It all clicks into place: A potent telomere‐targeting small molecule has been identified by using the copper‐free 1,3‐dipolar cycloaddition of a series of alkyne and azide building blocks catalyzed by a non‐Watson–Crick DNA secondary structure (see picture). This method rapidly identifies, otherwise unanticipated, potent small‐molecule probes to selectivelytarget a given RNA or DNA.
一切都按部就班:通过使用由非沃森-克里克 DNA 二级结构催化的一系列炔烃和叠氮化物构件的无铜 1,3-偶极环加成,已经鉴定出一种有效的端粒靶向小分子(参见图片)。这种方法可以快速识别出意想不到的有效小分子探针,以选择性地靶向给定的 RNA 或 DNA。

effective strategy for the development of norovirus therapeutics entails the discovery of inhibitors of norovirus 3CL protease, an enzyme essential for noroviral replication. We describe herein the structure-based design of the first class of permeable, triazole-based macrocyclicinhibitors of norovirus 3C-like protease, as well as pertinent X-ray crystallographic, biochemical, spectroscopic, and antiviral
由诺如病毒引起的急性肠胃炎暴发构成了全世界的公共卫生问题。迄今为止,尚无获批用于管理和预防诺如病毒感染的药物或疫苗。开发诺如病毒疗法的潜在有效策略需要发现诺如病毒 3CL 蛋白酶的抑制剂,这是一种对诺如病毒复制至关重要的酶。我们在此描述了基于结构的第一类诺如病毒 3C 样蛋白酶的可渗透、三唑基大环抑制剂的设计,以及相关的 X 射线晶体学、生化、光谱和抗病毒研究。
Structure and evaluation of antibacterial and antitubercular properties of new basic and heterocyclic 3-formylrifamycin SV derivatives obtained via ‘click chemistry’ approach
time because of the high volatility of substrates, an unexpected intramolecular condensation with the formation of 3,4-dihydrobenzo[g]quinazoline heterocyclic system took place. Structures of new derivatives in solution were determined using one- and two-dimensional NMR methods and FT-IR spectroscopy. Computational DFT and PM6 methods were employed to correlate their conformation and acid–base properties
