          <dc:description>トリパノソーマの寄生が原因であるシャーガス病は，顧みられない熱帯病の一つとして知られている．我々は，トリパノソーマに対する有効な治療薬の開発のため，核酸の構成に重要なピリミジンを合成するジヒドロオロト酸脱水素酵素を標的とした阻害剤の研究を行い，X 線構造解析によってこれらの阻害剤と標的蛋白質の複合体構造を明かにした．しかしながら，阻害機構を解明するためには阻害剤と蛋白質間の詳細な相互作用エネルギーを解析する必要がある．そこで本研究では，阻害剤と標的蛋白質のアミノ酸残基間の相互作用エネルギーをフラグメント分子軌道法を用いて解析した．その結果，リシンやアスパラギンとの水素結合が重要であることが明かになった．</dc:description>
          <dc:description>Chagas' disease caused by Trypanosoma cruzi is known as neglected tropical diseases (NTD's). To develop effective anti-Trypanosome drug, we remarked dihydroorotate dehydrogenase which assumed synthesis of orotic acid and studied inhibitor of the enzyme. Although X-ray structure of target protein with inhibitor is clarified, important protein-ligand interaction is not determined for elucidation of inhibition mechanism. Then, in this research, we analyzed interaction energy between target proteins and inhibitors using fragment molecular orbital method. As a result, it was revealed that hydrogen bonding with Lys and Asn was important. It is expected that these results are useful for anti-Trypanosome drug design.</dc:description>
