Abstract

Antioxidant compound can inhibit the oxidation of lipids and other biomolecules. The role of antioxidants is very important in neutralizing and destroying free radicals that can cause the damage to cells in the body. This research was carried out to design trolox derivate compounds as antioxidants using the QSAR method. The semi empirical AM1(Austin Model 1)method was used to generate the QSAR model. The statistical analysis result using multiple linier regression methods revealed thet antioxidant activity was influenced by the descriptors of qC1, qC4, qO7, qC13 and qO18. The QSAR equation model obtained was log IC50 = 0.821 + 7.067 (qC1) + 2.585 (qC4) + 4.812 (qO7) – 5.363 (qC13) – 0.887 (qO18) with the best predicted IC50 value was 4.699 µM. Keywords: Antioxidants, QSAR, semi empirical AM1, trolox

Abstract

In traditional Melayu Riau medicine, the jackfruit parasite plant, also known as Macrosolen cochinchinensis (Lour.) van Tiegh, has been utilized as a remedy for coughs, a treatment for cancer, a diuretic, and to speed up the recovery process after giving birth. Through in vitro and in silico testing, this investigation aims to learn more about the bioactive components and antibacterial activity of n-hexane, ethyl acetate, and ethanol obtained from the extracts of the jackfruit parasite plant (Macrosolen cochinchinensis (Lour.) van Tiegh. The disc diffusion method was used for the in vitro testing, and the molecular docking method was used for the in silico testing. Both were conducted against Staphylococcus aureus ATCC 12600 and Escherichia coli ATCC 25922. Each sample extract was prepared in three different concentrations (10%, 30%, and 50%), while chloramphenicol was used as the positive control. Inhibition zones of the extract against E. coli bacteria were found to be as follows: 6 mm, 8.4 mm, and 10.6 mm for the n-hexane extract; 8.2 mm, 10.7 mm, and 15.6 mm for the ethyl acetate extract; and 6 mm, 7.1 mm, and 14.1 mm for the methanol extract. The results of the test to determine the extract's antibacterial activity were as follows: The following is a list of the zones of inhibition that the extract has against S. aureus bacteria: 6 mm, 7.5 mm, and 13.7 mm in diameter for the extract of n-hexane; 12.8 mm, 14.2 mm, and 19.2 mm in diameter for the extract of ethyl acetate. Test results of 7.2 mm, 9.3 mm, and 15.3 mm were obtained for the methanol extract. In accordance with the findings of the study, the ethyl acetate extract of jackfruit parasite leaves exhibited the highest level of antibacterial activity, as measured by an inhibition zone diameter of 19.2 mm, when tested on S. aureus bacteria. In the meantime, the results of molecular docking of punicalin and rutin, which have been reported to have activity against proteins 6GOS.pdb and 1OJZ.pdb, have potential as antibacterials because they form 5 and 9 hydrogen bonds with important amino acids of the target protein, with cDOCKER values of -57.9239 and -88.3993, respectively. It suggests that punicalin and rutin can inhibit the growth of bacteria.
