Background: Atopic dermatitis (AD) is a chronic relapsing inflammatory skin condition which has a negative impact on children health. The well-known medicinal plant Centella asiatica extract (CE) is used in herbal skin care products to produce various pharmacological effects in dermatology. However, the molecular target of CE in suppressing inflammatory is largely unknown. Objective: the aim of this study was to examine anti-inflammatory properties and network pharmacology of CE in lipopolysaccharide (LPS)- induced AD in vitro model. Method: RAW264.7 cells were pre-treated with CE and then were stimulated with LPS and then were investigated cell viability, NO production, and the levels of pro-inflammatory mediators. In addition, the Search Tool for Retrieval of Interacting Genes (STRING), SwissTargetPrediction and the Kyoto Encyclopedia of Genes and Genomes (KEGG) were used to construct the defined mechanism of action and network pharmacology. Results: CE showed the potent inhibitory effects on LPS-induced NO. In addition, CE significantly suppressed the expression of iNOS and COX-2, as well as the production of IL-2, IL-6, IL-10, and TNF- α. Furthermore, the network pharmacological analysis revealed the potential role of CE in biological processes such as regulating JAK/STATs pathway and inhibiting proinflammatory cytokines both of which were linked to AD pathogenesis. Conclusion: Our findings confirm our hypothesis that CE could be developed as a therapeutic therapy for atopic dermatitis due to its pharmacological action and signaling mechanism in the modulation of allergic skin inflammation.

Centella asiatica is a traditional natural medicine used in a number of Southeast Asian nations. (also known as Centella asiatica L., Urb., or Gotu Kola). The aim of this study is to determine the antihyperuricemia properties of Centella asiatica extract and the possibility that they will interact with the XDH enzyme. The XDH enzyme is one of three enzymes that can influence the onset of hyperuricemia with the other two are SLC22A12 and ABCG2. In this research, we employ a computational method in collaboration with a number of applications and databases. ADME analysis was carried on for some Centella asiatica constituents to determine their similarities to the drug and bioavailability components. The analysis continued on with molecular docking between the chemical compounds and several enzymes related to hyperuricemia. According to the findings, Centella asiatica contains active constituents that can be used as an alternative therapy for hyperuricemia.

Hypertension is a silent killer that causes kidney, heart, and stroke damage if not handled properly. In Indonesia, the prevalence of the population with high blood pressure is 34.11\% with women 36.85\% higher than men 31.34\%, this shows a fairly high value so that special attention is needed on hypertension therapy. It is known that currently there are 6 types of pharmacological therapy for hypertension and one of the newest is the renin inhibitor class (Aliskiren). Indonesia has diverse natural wealth in the form of flora and fauna, with a wealth of more than 30,000 types of medicinal plants with 9500 potential herbal medicines that have not been utilized optimally, with the largest exporter of herbal medicines in the world. Centella asiatica plants containing triterpenoid saponins have high renin inhibitor activity, namely the content of Asiaticoside and Madecasoside. The research method was carried out in silico using molecular simulation and in vitro with fluorometry (328/552 nm) to test the activity of asiaticoside and madecasoside compounds as well as a mixture of asiaticoside and madecasoside in Centella asiatica plants. This is supported by the docking outcome. The docking results show that madecososide compounds have a gibbs energy close to the positive control aleskiren (-8.356 kcal/mol) and aleskiren (-9.44 kcal/mol). The experiment results showed that the triterpenoid saponin compound (madecassoside) contained an IC value of 0.71, at a concentration of 5 μg/μl, and absorbance of 1.35 A in the first minute. The strongest renin inhibition was Madecasoside compound with a concentration of 5 μg/μl with an average value of fluorescent adsorption and an average percent inhibition of 135\% with the best renin inhibition at Madecasoside 5 ug/ul the first minute with absorbance values 1.19 A. Finally, the in silico result corresponded to the in vitro experiment. Centella asiatica plants have renin inhibitor activity as antihypertensive, especially in secondary metabolites of triterpene saponins with pure madecasoside compounds compared with aliskiren as a renin inhibitor. So that the compound madecasoside has renin inhibitor activity as an antihypertensive.
