    Theoretical studies on the anticancer agents from selected marine natural products
    (Terengganu: Universiti Malaysia Terengganu, 2013-10) Nurul Fariha Yusof
    The aim of the present study is to find the molecular descriptors responsible for the variety of anticancer activities. In this study, fifty marine natural products molecules, those had confirmed to show anticancer activities experimentally, were selected to be evaluated their physical parameters using quantum mechanical software package Gaussian 09 at the theoretical level of B3LYP/DFT 6-310 (d,p). The outputs of this program such as SCF Energy, molecular orbital energies (LUMO, HOMO, energy band gap), dipole moment and thermodynamics properties (enthalpy, entropy, and free-energy of formation, ZPVE) along with other predictors ยท(molecular mass, number of selected atoms, number of aromatic and number of non-aromatic rings) were then statistically analyzed using statistical software package of SPSS version 20.0 by employing the principle component analysis procedure; taking only into consideration all the factor-loading of greater than 0.30.
