    • A method of rational drug design includes simulating polypeptides in a way that predicts the most probable secondary and/or tertiary structures of a polypeptide, e.g., an oligopeptide, without any presumptions as to the conformation of the underlying primary or secondary structure. The method involves computer simulation of the polypeptide, and more particularly simulating a real-size primary structure in an aqueous environment, shrinking the size of the polypeptide isobarically and isothermally, and expanding the simulated polypeptide to its real size in selected time periods. A useful set of tools, termed Balaji plots, energy conformational maps, and probability maps, assist in identifying those portions of the predicted peptide structure that are most flexible or most rigid. The rational design of novel compounds, useful as drugs, e.g., bioactive peptidomimetic compounds, and constrained analogs thereof, is thus made possible using the simulation methods and tools of the described invention.
    • 合理药物设计的方法包括以预测多肽(例如寡肽)的最可能的次要和/或三级结构的方式来模拟多肽,而没有关于下面的一级或二级结构的构象的任何推定。 该方法涉及多肽的计算机模拟,并且更具体地模拟水性环境中的实际一级结构,以等温和等温收缩多肽的大小,并在选定的时间段内将模拟多肽扩增至其实际大小。 一组有用的工具,称为Balaji图,能量构象图和概率图,有助于确定最灵活或最刚性的预测肽结构的那些部分。 因此,使用所述发明的模拟方法和工具可以合理地设计可用作药物的生物活性肽模拟化合物及其约束类似物的新化合物。
