项目摘要
The kinetics of biomolecular processes define many biomedical technologies and for this reason represent the fundamental basis for a large segment of pharmaceutical industries. Because of the problem complexity, computer simulations are the only available tool that can capture the mechanisms of binding at the required resolution level. Indeed, in many cases the processes are very short lived which makes them hardly detectable by experiment. Intermediate complexes that may be rate limiting can change the rates by orders of magnitudes rendering potential drug candidates inactive (or vice versa). Currently this can be checked only by expensive and time consuming experimental tests. Thus, the possibility of calculating the rates using computer simulation can make very significant impact on drug design studies.Attempts of incorporating a group of classical atoms into a continuum solvent (implicit solvent) are known for a long time. However, the most consistent approach describing a structured continuum, the hydrodynamics, is a direction that becomes active only very recently. Conceptually, modelling the MD particles in the 'transfer' region where the MD and CH domains overlap (the 'runaway' MD particles) remains the most pressing problem of essentially all approaches of this type.We propose a fundamentally new hybrid model that aims at solving this problem. It is based on a generalised description of the MD and CH components within the flux coupling approach. The proposed framework will ensure that the transition between the CH and MD representations is smooth and characterised by (i) the absence of numerical "fixes" such as artificial repulsive barriers between the atomistic and continuum parts or adding new particles, (ii) unified treatment of the solution parts using the same equations throughout the system's volume, (iii) the full control by a single empirical function that can be of arbitrary form both in space and time. The new method will lead to a large reduction of the simulation cost due to a large truncation of the MD domain, achieved without loosing either the detailed atomistic simulation in the MD zone or the macroscopic conservation laws for both mass and momentum.The project is a well balanced combination of state of the art computer hardware development, advanced numerical modelling (the triad of molecular dynamics, continuum fluid mechanics, and numerical methods) and cutting edge investigation of biomedically important molecular system.
生物分子过程的动力学定义了许多生物医学技术,因此代表了制药工业的一大部分的基本基础。由于问题的复杂性,计算机模拟是唯一可用的工具,可以捕捉到所需的分辨率水平的绑定机制。事实上,在许多情况下,这些过程非常短暂,这使得它们很难通过实验检测到。可能是速率限制的中间复合物可以改变速率的数量级,使潜在的候选药物失活(反之亦然)。目前,这只能通过昂贵且耗时的实验测试来检查。因此,使用计算机模拟计算速率的可能性可以对药物设计研究产生非常显著的影响。然而,描述结构化连续体的最一致的方法,流体动力学,是一个最近才变得活跃的方向。从概念上讲,在MD和CH域重叠(“失控”MD粒子)的“转移”区域中的MD粒子建模仍然是基本上所有这种类型的方法中最紧迫的问题。我们提出了一个全新的混合模型,旨在解决这个问题。它是基于广义描述的MD和CH组件内的磁通耦合方法。所提出的框架将确保CH和MD表示之间的过渡是平滑的,并且其特征在于(i)不存在数值“修复”,例如原子和连续部分之间的人工排斥屏障或添加新粒子,(ii)在整个系统的体积中使用相同的方程统一处理解决方案部分,(iii)由一个在空间和时间上都可以是任意形式的单一经验函数进行完全控制。新方法将大大减少模拟成本,因为大幅度截断了MD区域,而不会失去MD区域的详细原子模拟或质量和动量的宏观守恒定律。(分子动力学,连续流体力学和数值方法的三合一)和生物医学重要分子系统的前沿研究。
