A chemically diverse library of TAGE-triazole conjugates was synthesized utilizing click chemistry on the TAGE scaffold. This library of small molecules was screened for anti-biofilm activity and found to possess the ability of inhibiting biofilm formation against Acinetobacter baumannii, Staphylococcus aureus and Pseudomonas aeruginosa. One such compound in this library demonstrated the most potent inhibitory effect against Staphylococcus aureus biofilm formation that has been displayed by any 2-aminoimidazole derivative.
利用 TAGE 支架上的点击化学,合成了一个具有化学多样性的 TAGE 三唑共轭物库。对该小分子化合物库进行了抗生物膜活性筛选,发现其具有抑制鲍曼不动杆菌、金黄色葡萄球菌和铜绿假单胞菌形成生物膜的能力。该化合物库中的一个化合物对金黄色葡萄球菌生物膜形成的抑制作用是所有 2-氨基咪唑衍生物中最强的。
From Synthetic Simplified Marine Metabolite Analogues to New Selective Allosteric Inhibitor of Aurora B Kinase
(37). Here we present the synthesis of new inhibitors of Aurora Bkinase, which is an important target for cancer therapy through mitosis regulation. The biologically oriented synthesis yielded several nanomolar inhibitors. The optimized compound CJ2-150 (37) showed a non-ATP competitive allosteric mode of action in a mixed-type inhibition for Aurora Bkinase. Molecular docking identified a probable binding

Reaction of pyrrole‐2‐carboxamides with Selectfluor in MeCN/water (4:1) affords 2‐hydroxy‐5‐oxopyrrole‐2‐carboxamides in yields of up to 80 %. A variety of sensitive functional groups is tolerated, among them aldehydes and alkynes. The new method also works in the presence of allyl groups and appears to be superior to the use of singlet oxygen. Reaction of the monobrominated dihydropyrrolo[1,2‐a]pyrazinone
