·The research direction of Professor Yu Zhixiang's research group

Many drug molecules and active natural product molecules have complex ring structures, which is often one of the biggest challenges for chemists to synthesize these molecules. In response to this scientific problem, Professor Yu Zhixiang's team at Peking University has developed and is developing a series of new ring-forming reactions to provide chemists with powerful practical tools for synthesizing cyclic skeletons, thereby facilitating the efficient synthesis of natural products and drug molecules. These reactions can also synthesize some new skeletons that have not yet been discovered in nature, which can expand the chemical space of drug discovery. At present, the new ring-forming reactions that have been developed include: [5+2+1] reaction, [7+1] reaction, benzo [7+1] reaction to construct eight-membered carbon rings; [5+2] reaction, [4+2+1] reaction, disene-diyne cyclic isomerization reaction (6/7/5, 6/7/6, 5/7/5, 5/7/6 ring system) to construct heponetal carbon rings; [5+1] reaction, [3+2+1] reaction to construct a six-membered carbon ring; Three [3+2] reactions and one dilute diene ring isomerization reaction for constructing five-membered carbon rings. Yu Zhixiang's research group applied the [5+2+1] reaction, [3+2+1] reaction, [5+1] reaction, etc. to the synthesis of multiple complex natural products such as Asteriscanolide, Hirsutene, Glathamine (treatment of Alzheimer's disease), etc. Professor David Chen of Seoul National University in South Korea used the dilute diene cyclic isomerization reaction of Yu Zhixiang's group to complete the synthesis of the natural product Dendrobine; Professor Lei Xiaoguang of Peking University used the [3+2+1] reaction of Yu Zhixiang's group to complete the total synthesis of enantio-kauridine tetracyclic diterpene natural products.

Professor Yu Zhixiang is mainly engaged in combining theoretical calculation with organic synthesis, studying the mechanism of organic chemical reactions, developing new methods of organic synthesis, and applying them to the synthesis and post-modification of natural products and drug molecules. At present, the mechanisms of more than a dozen important chemical reactions such as Lu-[3+2] cycloaddition reaction, metal-catalyzed cycloaddition reaction, and carbene insertion reaction have been deeply studied: the important phenomenon that water and other proton donors are required as catalysts in the process of [1,2]-proton migration has been found and verified theoretically and experimentally; A new semi-quantitative front-line molecular orbital method is proposed to semi-quantitatively calculate the activation energy of the reaction as well as the nucleophility and electrophility of the molecule. Cyclic reactions such as [3+2], [5+1], [3+2+1], [4+2+1], [7+1], [5+2+1] and other cyclic reactions for the synthesis of different ring molecules were developed, and applied to the synthesis of multiple natural products.

  余志祥教授的药物研发课题组将依托深圳湾实验室坪山生物医药研发转化中心，主要利用他们所发展的成环反应为合成工具，构建多环分子化合物库，以及合成具有重要生物活性的天然产物和类似物，从而寻找可以用于治疗癌症，神经退行性疾病以及抗病毒的先导化合物，并期望能将这些分子推向临床研究。同时课题组还将与合作者一起对这些活性分子与生物靶标的作用机制等相关化学生物学问题进行探讨，以期推动药物化学和化学生物学的发展。
