Abstract

Cancer is one of the leading causes of human death. In 2019, it was reported that cancer was the second (22%) cause of death due to non-communicable diseases in the world's population. Research for alternative anticancer drugs is still being done, including anticancer from plants. One of the plants that have the potential to be developed as an anticancer alternative is the sungkai plant. Sungkai leaves contain many bioactive compounds, one of which is the clerodane-type diterpenoids, peronemins, A2 (1), A3 (2), B1 (3), B2 (4), B3 (5), C1 (6), and D1 (7). The aim of this study was to initial screen the potential of seven Peronemins compounds in Sungkai leaves extract as anticancer candidates. Initial screening was carried out by predicting in-silico anticancer activity of the seven compounds. Dihydrofolate reductase inhibitor (DHFR inhibitor) is one of the anticancer activity screening approaches. DHFR Inhibitor activity from perenomins derivatives with pIC50 values ​​of 0.785 (A2), respectively; 0.785 (A3); 0.799 (B2); 0.799 (B3); 0.799 (C1 and D1). In addition, from compounds 1,2,3,4,5 peronemin derivatives have potential anticancer activity through interaction with the target protein Voltage-gated potassium channel subunit while compounds 6, 7 also have biological activity potential anticancer on target protein Dihydrofolate reductase.

Abstract

Putat leaves (Planchonia valida) are a plant that is traditionally used by people in the Tanjung Lanjut areas, Jambi as fresh vegetables, and as a traditional medicine to treat skin diseases and restore health. This identifies that the putat plant contains chemical compounds that have the potential to have antioxidant activity. Extraction was carried out using n-hexane and ethyl acetate solvents using multistage maceration. Next, phytochemical screening and antioxidant activity tests are carried out to obtain information about fractions that can potentially proceed to the isolation stage. In the maceration process, an extract percentage was obtained with a yield value of 1.39%. Next, isolation was carried out using vacuum liquid chromatography. The isolates obtained were then characterized using UV-Vis and FT-IR spectrophotometer instruments. The isolate obtained was in the form of a wet solid, and if seen through characterization, it belonged to the class of steroid compounds; it was suspected to be an ergosterol compound. Antioxidants are known to have the ability to inhibit and reduce the presence of free radicals in the human body. In this study, antioxidant activity was tested using the DPPH (2,2-diphenyl-1-picrihidazil) method on F1 isolates. The F1 isolate obtained was proven to have antioxidant activity with a value of 99.2265 ppm, which is classified in the strong antioxidant activity range.
