主要学术成绩
近年来在发展QM/MM方法,溶剂化理论、虚拟药物筛选方法等方面取得了重要的科研成果。所发展并程序化的QM/MM-FE方法是是目前研究酶的催化反应基本反应机理的最有力的工具;所开发的SMVLE溶剂化方法是目前预测绝对溶剂化能最为准确的方法。目前在J Am Chem Soc,J Phys Chem B,J Chem Theory Comput,J Comput Chem等SCI收录的顶级和一流的杂志中共发表学术论文18篇,总影响因子>88,他引总次数>260,H指数13。
特别是在QM/MM方法发展方面,通过修改Gaussian 03和AMBER8程序发展并重新程序化了pseudobond QM/MM-FE方法。该方法既能在量子化学级别下进行反应坐标计算,又能同时有效考虑酶环境对反应进程的影响,是研究酶的催化反应机理最有力的计算工具之一,能为合理化设计高活性突变酶提供可靠的结构和机理信息。目前已利用该方法进行了一系列酶的催化反应机理、高活性突变酶的设计等方面的研究工作,包括能高效降解可卡因的BChE突变酶的设计、可卡因酯酶催化水解可卡因的基本反应机理的研究、BChE高活性突变酶对可卡因、乙酰胆碱、硫代乙酰胆碱等底物的水解机理的研究、AChE-dimethylphosphoryl重活化机理的研究等等。借助该方法,我们设计出来的BChE工程酶水解可卡因的效率比野生酶提高了~2000倍,能有效地保护试验鼠在注射致死剂量(> LD100)的可卡因之后依然存活,是降解可卡因最快的酶,目前该BChE工程酶的研究已进入临床二期阶段。
