IN SILICO TEST AND CHARACTERIZATION TEST OF THE NANOEMULSION FORMULA OF CATECHIN COMPOUNDS AS ANTI ACNE

Abstract

Catechin is a polyphenolic compound produced by green tea and gambier plants with catechin activity as an antibacterial. The method that can be used to predict the activity of catechin compounds as anti-acne is by using the in silico method and catechins are unstable because they are difficult to dissolve in water, making transdermal delivery inefficient. As a drug delivery system, nanoemulsions can increase the effectiveness of drug therapy by reducing the particle size to the nanometer range. The aim of this research is to find out how to test in silico protein (1VJY) with catechin compounds as an anti-acne agent and to find out how the evaluation and characterization of the nanoemulsion preparation formula from catechin compounds meets the specified requirements. The results of in silico testing can predict catechin compounds as antibacterials that inhibit protein mechanisms (1VJY) as shown by 2D visualization and docking values and evaluation test results of catechin nanoemulsion preparations such as organoleptic, pH, transmittance, freeze and thaw, viscosity, specific gravity, irritation test has fulfilled the specified requirements. The results of the characterization test for the catechin nanoemulsion preparation showed a particle size of 10.6 nm, a polydispersity index of 0.452, and a zeta potential of -34.5 m, which is in accordance with the requirements.
