Introduction: Oxidative stress is one of the inflammatory events caused by obesity. This condition is characterized by an increase in various inflammatory markers, such as intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1), and a cluster of differentiation 40 (CD40). This study aimed to analyze the effect of Plectranthus amboinicus (Lour.) Spreng ethanol extract on ICAM-1, VCAM-1, and CD40 in obese rats. Methods: The study used a pure experimental method with a completely randomized design. There were 6 groups, namely, C- (negative control), C+ (positive control), CMC (soluble control), EE300 (P. amboinicus ethanol extract, 300 mg/kg body weight [BW]), EE600 (P. amboinicus ethanol extract, 600 mg/kg BW) and EE900 groups (P. amboinicus ethanol extract, 900 mg/kg BW). Results: The results showed low levels of ICAM-1 and VCAM-1 in the blood plasma, especially in the EE900 group, but the difference was not substantial. The same trend also occurred in the expression of CD40 in the tunica intima layer of the rat aorta. Conclusions: Thus, the administration of 900 mg/kg BW P. amboinicus ethanol extract for 45 days has the potential to treat obesity in rats through the suppression of oxidative stress and inflammatory markers (ICAM-1, VCAM-1 and CD40).

Background: Plectranthus amboinicus (Lour.) Spreng is a plant that has a high flavonoid content. The leaves of Plectranthus amboinicus (Lour.) Spreng contain many flavonoids Chrysoeriol, Cirsimaritin, Eriodictyol, Luteolin, Rutin, Salvigenin, Thymoquinone, Quercetin, Apigenin, and 5-O-Methyl-Luteolin. Objectives: To determine the antioxidant activity and anticancer activity of flavonoid compounds contained in Plectranthus amboinicus (Lour.) Spreng. Methods: Anticancer activity testing was carried out by in silico against several cancer receptors and antioxidant activity testing was carried out by in vitro using the 1,1-Diphenyl-2-Picryhydrazil method. The results showed that the flavonoid compounds contained in Plectranthus amboinicus (Lour.) Spreng have similar anticancer activity to the reference molecule at the P-Glycoprotein-1, Cyclin Dependent Kinase-2, and Phosphoinositide-3-Kinase receptors, as well as better anticancer activity than the reference molecule for the Cyclooxygenase-2 and Phosphoenolpyruvate Carboxykinase receptors. Results: The antioxidant activity of the extract gave an Inhibitory Concentration 50\% value of 9.77 μg/mL, the flavonoid compounds contained in Plectranthus amboinicus (Lour.) Spreng gave an Inhibitory Concentration 50\% value that lower than the extract, which ranged from 6.92 μg/mL to 8.50 μg/mL. Flavonoids in Plectranthus amboinicus (Lour.) Spreng anticancer activity by in silico molecular docking and antioxidant activity by in vitro 1,1-Diphenyl-2-Picryhydrazil method. Conclusions: All the flavonoid compounds contained in the ethanolic extract of Plectranthus amboinicus (Lour.) Spreng leaves exhibit very strong anti-cancer and antioxidant activity, which results in ethanolic extract of Plectranthus amboinicus (Lour.) Spreng leaves have very strong antioxidant activity.
