Abstract

The semiempirical method is a method that can be selected in computational chemistry. This method can be used to study the stability and reactivity of cyclopolic acid compounds and their derivatives. This method is simple method in optimizing a compound in calculating the parameters possessed by the atom. Cyclopolic acid is an organic compound that can be found in corn and beans. Analysis using two methods on HyperChem Professional application are AM1 and PM3. Analysis Result shows that the total energy and gradient of each compound do not have significant differences in calculations. As in the structure of 2-formyl-3-(hydroxymethyl)-6-methoxy-5-methylterephthalic acid has a total energy of -80608.1868567 (kcal/mol) and a gradient of 0.0898817 (kcal/mol/Ang) with the AM1 method and total energy of -74935.9180118 (kcal/mol) and a gradient of 0.0874369 (kcal/mol/Ang) with the PM3 method. The stable structure is in the structure of the 2-formyl-3-(hydroxymethyl)-6-methoxy-5-methylterephthalic acid based on the calculation of the total energy and gradient. Meanwhile, according to the calculation of the difference between LUMO-HOMO, it has different results. Where according to the calculation of the energy difference between LUMO-HOMO, the most stable compound structure is the structure of 2-formyl-3-(hydroxymethyl)-4-isocyano-6-metoxy-5-methylbenzoic acid but is not reactive. Likewise, the 2-formyl-4-hidroxy-3-(hydroxymethyl)-6-methoxy-5-methylbenzoic acid, 2-formyl-3-(hydroxymethyl)-6-methoxy-5-methyl-4-(oxo-λ6-methyl)benzoic acid and 2-formyl-3-(hydroxymethyl)-6-methoxy-5-methylterephthalic acid are reactive but unstable compound structure.

Abstract

Research on the activity of eugenol derived compounds as antimicrobials using the qualitative structure-activity relationship (QSAR) model has been conducted. Molecular structure modeling was executed computationally using the ChemDraw Ultra 12.0 program package. Geometry optimization was performed using AM1 semi-empirical method to stabilize structure with the least energy level. Calculations of hydrophobic, electronic, and steric descriptors were done using Gaussian-09 and Marvin Sketch 64 softwares. Statistical calculations was conducted through multiple linear regression method using the IBM SPSS 25 program. Statistical analysis was carried out based on the statistical requirements of several equation models so that the best equation model was obtained. The analysis with the QSAR equation model obtained that the model 1 equation presented the best results.
