Abstract

Indonesia is one of the most abundant in natural resources countries in the world. The bay leaves are well- known among the locals and have various pharmacological properties, including anti dyslipidemia. Currently, the use of nanoparticle technologies in dyslipidemia treatment is quite popular. These treatments have numerous advantages such as enhancing the potency of dyslipidemia agents. The purpose of this study is to develop chitosan-based nanoparticles made from Syzygium polyanthum leaves extract using crosslink method. Chitosan is used as the polymer and STPP as the crosslinker with the ratio of chitosan:STPP is 5:1. Two formula is generated, F1 is chitosan-based nanoparticle extract and F2 is chitosan-base nanoparticle blank. Syzygium polyanthum extract contains alkaloid, flavonoid, saponin, quinone, and tannin, as determined by secondary metabolites screening. The total flavonoid content of Syzygium polyanthum leaves extract determined as quercetin is 0.04%. Physical properties of generated nanoparticles such as size, polydispersity index (PI) and zeta potential are investigated. Particle sizes of nanoparticles F1 and F2 are 180.1 ± 0.5 nm and 464.3 ± 25.98 nm with the PI values of F1 and F2 are 0.220 ± 0.02 and 0.563 ± 0.112 respectively. Zeta potential value for F1 is 21.8 ± 1.74 mV and F2 is 17.8 ± 0.21 mV. The entrapment efficiency is evaluated to determine the extract content of the nanoparticle, and the result is 47.13%. From this research, the chitosan-based nanoparticles containing Syzygium polyanthum formula have good physical properties. Further investigation is needed to evaluate its potential as anti-dyslipidemia.

Abstract

South Lampung Regency is the second largest cocoa bean producer in Lampung Province. This natural resource is very abundant, one of which is in Tarahan Village, South Lampung, but until now it has not been optimally processed and is only sold in the form of dry brown beans which have low selling value. This is because the villagers does not know how to process cocoa beans into cocoa products. Therefore, this service program aims to assist the target community in processing cocoa beans into ready-to-sell products (jam and mask) to improve people welfare. This activity consisted of providing material and training in making jam and chocolate masks for 1 day. After the training, the villagers were able to understand and practice making the chocolate jam and mask. This program is expected to increase chocholate selling value as local regional commodities.

Abstract

NAT2 serves as the key enzyme responsible for metabolizing the INH compound, with its expression and functional activity significantly contributing to the risk of hepatotoxicity. Due to the possible inhibitory role of curcumin on NAT2, it is important to assess its effect on the metabolic processing of INH and to examine the enzyme-related interactions that may occur between drugs. Molecular docking studies demonstrated that curcumin can localize in the hydrophobic pocket and form a strong bond with NAT2. The aim of this study was to predict the potential interaction of the isoniazid and curcumin compounds against NAT2 protein. In this study, NAT2 protein (PDB ID: 2PFR) was used as a receptor. The results obtained showed the binding energies of native ligand, isoniazid, and curcumin were -5.78, -4.47, -8.35 kcal/mol, respectively. The findings of this research suggest that curcumin is capable of suppressing NAT2 activity, thereby affecting the pharmacokinetics of INH. These results may offer insights into minimizing INH-related liver toxicity and enhancing its effectiveness through co-administration with curcumin.
