Abstract

Uncaria cordata (Lour. Merr. is one plants genus Uncaria growing in Indonesia, there has been no publication content of secondary metabolites are active as antioxidants. Antioxidant activity by DPPH test (1,1-diphenyl-2 pikrilhidrazil) generate IC50 n-hexane extract did not have IC50 values ​​and can only inhibit 34.234% at a concentration of 1000 µg/mL, ethyl acetate extract of 704.478 µg/mL, methanol extract of 6.778 µg/mL. Methanol extract with the highest IC50 isolation by column chromatography and obtained compound isolates F2. In the test with the Lieberman Burchard color reagent terpenoids positive (red) compounds derived from class terpenoids possibility. The results UV spectrum gives maximum absorption at a wavelength of 293.50 nm and 310.5 nm. Infrared spectrum showed absorption 3410 cm-1 (OH), 2933 cm-1 (CH), 1690 cm-1 (C = O), 1457 cm-1 (CH), and 1036 cm-1 (CC). The antioxidant activity (IC50) F2 compounds have not active category.

Abstract

Breast cancer, particularly the HER2-positive subtype, remains a major global health burden. Medicinal plants are increasingly being explored as sources of anticancer agents due to their chemical diversity and multitarget mechanisms of action. Uncaria nervosa Elmer, an Indonesian ethnomedicinal plant, has shown promising anticancer potential; however, evidence at the subfraction level is limited. This study aimed to evaluate the cytotoxic activity and the inhibitory effect on cell migration of the polar subfraction (SF-I) derived from the ethyl acetate fraction of Uncaria nervosa leaves against MCF-7/HER2 breast cancer cells. Cytotoxicity was assessed using the MTT assay, and cell migration was analyzed using the scratch-wound healing assay. The polar subfraction (SF-I) exhibited dose-dependent cytotoxicity and significantly inhibited cell migration at sub-cytotoxic concentrations. These findings indicate that polar constituents of Uncaria nervosa exhibit dual anticancer activity by suppressing cancer cell viability and motility, supporting their potential development as phytopharmaceutical candidates for HER2-positive breast cancer.
