Outline of Final Research Achievements

Most of the chemical reaction occur in the molecular assembly, which is fluctuating at a given temperature. The free energy analysis is necessary to evaluate such chemical reactions considering the thermal fluctuations and the entropy effects.
In this study, both the optimization method of the free energy minimum path, and then the free energy contribution analysis method were developed based on the computer simulation technique. The molecular modification technique were also established to enhance or reduce the focused reaction using the free energy contribution analysis.

Academic Significance and Societal Importance of the Research Achievements

高い信頼性を維持しつつ、自由エネルギーの成分を原子間の寄与として明確化した点は大きな学術的意義をもつ。一般に、複雑な相互作用と熱揺らぎを含む結果として得られる自由エネルギーを、部分的な寄与に分割できることは、温度や環境の影響を取り入れた反応制御の方法が確立するために、不可欠である。
同時に、着目する生体反応を抑制するような薬品の開発にも生かすことができる点で、社会的意義も大きい。生体反応に深くかかわる酵素反応を周辺アミノ酸配置からの寄与として分割することで、自由エネルギーにもっとも深く影響を及ぼす分子を目的通り設計できる道筋がつけられたことから、強力な反応制御の新薬開発への発展が期待できる。
