A fast and efficient palladium‐catalyzed fourfolddomino Sonogashira/double‐carbopalladation/CH‐activation reaction that converts simple aromatic systems into complex polycyclic hydrocarbons has been developed. A number of substituted products has thus been prepared in yields up to 89 %. The structural assignment has been confirmed by using single‐crystal X‐ray crystallography. The products show intriguing
一种快速和有效的钯催化的四倍多米诺的Sonogashira /双carbopalladation / C H-活化反应,其将简单芳族体系成复杂的多环烃已经研制成功。因此已经制备了许多取代的产物,产率高达89%。通过使用单晶X射线晶体学已确认了结构分配。该产品显示出令人着迷的荧光活性,因此可以用作化学传感器或荧光成像染料。

Twenty-seven novel furancarboxamide derivatives with a diphenyl ether moiety were synthesized and evaluated for their antifungalactivity against Rhizoctonia solani, Botrytis cirerea, Valsa mali and Sphaceloma ampelimum. Antifungal bioassay results indicated that most compounds had good or excellent fungicidal activities for R. solani and S. ampelimum at 20 mg L−1. Among synthesized compounds, compound
合成了具有二苯醚部分的二十七种新颖的呋喃甲酰胺衍生物,并评估了其对茄状枯萎病菌,蜡状葡萄孢菌,马来酸缬草和安非球菌的抗真菌活性。抗真菌生物测定结果表明,在20 mg L -1时,大多数化合物对sol。R. solani和S. ampelimum具有良好或优异的杀真菌活性。在合成的化合物中,化合物18e对氨苄青霉有更大的抑制作用,最大有效浓度(EC 50)值的一半为0.020 mg L -1。这种强大的活性可与目前使用的商业杀菌剂(例如Boscalid和多菌灵)竞争,并且作为新型杀菌剂未来开发的主导化合物具有巨大的潜力。

remained intractable to direct targeting because much of MYC is intrinsically disordered. Here, we have performed a cysteine-reactive covalent ligand screen to identify compounds that could disrupt the binding of MYC to its DNA consensus sequence in vitro and also impair MYC transcriptional activity in situ in cells. We have identified a covalent ligand, EN4, that targetscysteine 171 of MYC within a predicted
This invention relates to aryl carbonyl derivatives which are activators of glucokinase which may be useful for the management, treatment, control, or adjunct treatment of diseases, where increasing glucokinase activity is beneficial.
