Abstract

Acne can be caused by dust, sweat, and dirt that stick to the skin, forming blackheads. When blackheads become infected with bacteria, inflammation can occur. Therefore, it is essential to maintain good skin hygiene. One way to do this is by using natural ingredients with antibacterial properties. Red betel leaf is known to have antibacterial activity. This study aims to create a facial wash using red betel leaf extract that exhibits antibacterial properties against Propionibacterium acnes. The red betel leaf was extracted using the maceration method. Antibacterial testing was conducted against Propionibacterium acnes bacteria using the suitable diffusion method with a combination of red betel leaf extract at 10%, 15%, and 20%. The study found that facial wash products containing extract concentrations of 10%, 15%, and 20% demonstrated good physical stability, meeting the requirements of SNI-19-4380-1996 for pH, viscosity, specific gravity, and foam height. Additionally, the products showed potent antibacterial activity against Propionibacterium acnes bacteria, with inhibition zones of 29.0 mm, 32.6 mm, and 35.3 mm for the 10%, 15%, and 20% concentrations, respectively.

Abstract

Tuberculosis remains a major public health concern due to emerging cases of drug resistance. To overcome this issue, the effectiveness of antitubercular medications must be reinforced. One of the methods that can be used is using active targeting, which involves small molecules that bind to a specific receptor. In this research, we study the potential of N-hydroxysuccinimide (NHS) folate to be used as the targeting agent against the GAPDH (glyceraldehyde-3-phosphate dehydrogenase) cell-surface receptor, a common virulence factor found on many pathogenic bacteria, including Mycobacterium tuberculosis. We conducted this research using computational methods, specifically molecular docking and molecular dynamics simulation. Based on the evaluation of molecular docking and molecular dynamics simulation results, NHS-folate is predicted to have a huge potential to be an active targeting agent against the GAPDH receptor of Mycobacterium tuberculosis.

Abstract

HAMIN® is a self-emulsifying base composed of a mixture of hydrogenated palm kernel oil and hydrogenated palm kernel stearin. This formulation not only enhances the aesthetic quality of products but also simplifies the manufacturing process, as it eliminates the need for additional emulsifying agents to form a stable cream. Due to these properties, HAMIN® is considered highly suitable for the development of both pharmaceutical and cosmetic formulations. Despite its potential applications, no prior research has investigated the optimal ratio of HAMIN® palm fat base to distilled water distilled waterrequired to achieve desirable physical characteristics and drug release properties in cream formulations. Therefore, this study aims to determine the optimum composition of HAMIN® palm fat base and distilled water for the formulation of diphenhydramine hydrochloride cream. The optimization process was conducted using the simplex lattice design (SLD) method, a statistical approach commonly employed to evaluate and optimize multicomponent formulations. The experimental results demonstrated that increasing the concentration of HAMIN® palm fat base had a dominant effect on enhancing the pH, viscosity, adhesion, and stability of the cream. Conversely, a higher concentration of distilled water significantly improved spreadability, extrudability, and drug release flux. These findings indicate that the selection of base composition plays a crucial role in determining the overall performance of the cream formulation. The optimal formulation, as determined through SLD analysis, consisted of 41.667% HAMIN® palm fat base and 48.333% distilled water, achieving a desirability index of 0.649. This composition represents the most balanced formulation in terms of physical stability and drug release, making it a promising candidate for further pharmaceutical and cosmetic applications.
