基于結(jié)構(gòu)的理性設(shè)計(jì):扎那米韋和奧塞米韋
[Abstract]:New drug creation is a complex intellectual activity involving multi-dimensional scientific and technological activities such as scientific research, technological creation, product development and medical effects. Each drug has its own R & D track, and the construction of chemical structures is the most important step because it covers pharmacodynamics, pharmacology, safety and biopharmaceutical properties. This column analyzes and interprets the successful construction of representative drugs from the perspective of drug chemistry. Based on the crystal structure and biochemical study of influenza neuraminidase and taking the transition state of substrate as the starting point, the results of molecular simulation were used to guide the design of inhibitors. Among the limited compounds designed and synthesized, the first zanamivir was born. However, due to excessive restraint and imitation of substrate structure, excessive polarity leads to zanamivir defects and drug limitations. Ox is also based on the three-dimensional structure of enzymes and mimic the substrate transition state, but noted the requirements of drug formation, but also in a few compounds, successfully synthesized a simple and reasonable structure of oral antiinfluenza drugs. In the order of R & D and marketing, Osevir is a successor, but surpasses the first Zanamivir.
