Abstract

Phenylamine derivatives are substances that have a biochemical action and are widely applied as psychotropic drugs. In particular, with regard to the quantitative analysis of substances such as ephedrine, amphetamine, pentermine, and dopamine, many previous studies such as electrochemical, vacuum ultraviolet method, and gas chromatography have been conducted. However, there have not been many studies on the structural characteristics of molecular units. Therefore, In this study, we used (HyperChem8.0's, HC) semi-empirical PM3 method to calculate the total energy, band gap, electrostatic potential, and net charge of ephedrine, amphetamine, pentamine and dopamine to investigate the chemical properties of each derivative according to the molecular structure change. The results showed that for total energy -43,171.8, -32,9538.3, -36,407.3 and -43,061.2 Kcal/mol, respectively, while for band gaps, 10.16379377, 9.9531666, 9.7878002 and 9.0589282 eV. Also, for electrostatic potentials, 1.301~-0.045, 1.694~0.299, 0.694~-0.158 and 1.587~-0.048 respectively. Finally, looking at the distribution of net charges, the oxygen atoms, nitrogen atoms and carbon atoms were -0.312~-0.242, -0.161~-0.051 and +0.13~-0.12 respectively. These results are expected to lead to chemical action centered on phenyl radicals and oxygen and nitrogen atoms common to phenethylamine derivatives.

페네틸아민 유도체는 생화학적 작용을 하는 물질로 향정신성 약물로 많이 응용되고 있다. 특히 에페드린, 암페타민, 펜터마인 그리고 도파민과 같은 물질의 정량적 검출과 관련해서는 전기화학적, 진공자외선법, 그리고 가스크로마토그래피법 등의 선행연구가 많이 진행되었다. 그러나 분자 단위의 구조적 특성에 따른 연구는 많이 보고되지 않았다. 따라서 이 연구에서는 페네틸아민 유도체의 구조적 특성을 알아보기 위하여 (HyperChem8.0, HC)의 반경험적 PM3 방법을 이용하여 에페드린, 암페타민, 펜터마인 그리고 도파민의 전체에너지, 밴드갭, 정전포텐셜, 전하량을 계산하여 각 유도체의 분자구조적 변화에 따른 화학적 특성을 조사하였다. 그 결과 총에너지의 경우 -43,171.8, -32,9538.3, -36,407.3 그리고 -43,061.2 Kcal/mol로 각각 나타났으며 밴드 갭의 경우 10.1637937, 9.9531666, 9.7878002 그리고 9.0589282 eV로 나타났다. 또한, 정전포텐셜의 경우 1.301~-0.045, 1.694~0.299, 0.694~-0.158 그리고 1.587~-0.048로 각각 나타났다. 마지막으로 알짜전하 분포를 살펴보면 산소 원자, 질소 원자 그리고 탄소 원자의 경우 각각 -0.312~-0.242, -0.161~-0.051 그리고 ＋0.13~-0.12로 나타났다. 이와 같은 결과는 페네틸아민 유도체에 공통으로 존재하는 페닐기와 산소 및 질소 원자를 중심으로 화학작용이 진행될 것으로 예상한다.
