Abstract

Purple sweet potato leaves (Ipomea batatas Ver.) has been proven to have anti-lithiasis effects in vitro in treating kidney stone disease. This is due to the high content of potassium in the leaves. The study aimed to analyze the effect of purple sweet potato leaf extract on kidney stone decay in male white rats induced by ethylene glycol 0.75% and ammonium chloride 2% for 10 days. In this study, 24 mice were divided into 6 groups: normal or without induction group, positive control, negative control, dose group 300 mg/200-gram body weight, 400 mg/200-gram body weight, and 500 mg/200-gram body weight. The parameters observed were calcium levels in the urine tested using Atomic Absorption Spectrophotometry, oxalate levels in urine tested using UV VIS Spectrophotometer. The results of this study indicate that purple sweet potato leaf extract at a dose of 500 mg/200-gram body weight can increase the levels of calcium and oxalate in the urine of rats compared with negative controls.

Abstract

Heliannuol is a sesquiterpene that has a benzoxepine ring, oxepin. Many derivatives of benzoxepine compounds show anticancer activity by inhibiting the phosphoinositide 3-kinase (PI3K) enzyme. These enzymes play a role in cell proliferation and growth. The study aims to predict the physicochemical properties using Lipinski’s Rule of Five parameters on phosphoinositide 3- kinase (PI3K/Mtor; PDB 5OQ4) enzyme and the toxicity of Heliannuol A, B, C, D, E compounds. The process uses the pkCSM online tool. The validation of receptor 5OQ4 is done using the value parameter RMSD < 2 (Å). Protox online tool dan pkCSM online tool is employed to predict the toxicity using parameter LD50, skin sensitization, Ames toxicity, hepatotoxicity, and toxicity class. The interaction of ligan and enzyme is tested using Molegro Virtual Docker 6.0. Heliannoul A, B, C, D, E compounds fulfill Lipinski’s Rule of Five. The receptor 5OQ4 is known valid using the value of RMSD 0,923 (Å). Heliannuol A, B, C, D, E compounds inhibit Dual PI3K / mTOR enzyme less than Bimiralisib. As a result of the toxicity test of compounds Helliannouls A, B, C, E, and Bimiralisib compounds are included in class 4, while Helliannouls D compounds are included in class 5.

Abstract

Green tea catechin compounds (Camellia sinensis L. Kuntze) have an antiviral activity such as influenza, hepatitis B, hepatitis C, herpes simplex virus, HIV, and proven in vitro antiviral influenza against NSP5 in SARS CoV. These considerations are used in this study using Non-structural Protein (NSP), namely NSP3 and NSP5 in SARS CoV-2, which have a role in viral replication and transcription. This study aims to predict the physicochemical properties according to the five rules of Lipinski's using swissADME. Prediction of toxicity with LD50 classification using the Protox II online tool. Catechin compound activity based on ligand interaction with NSP3 (PDB ID: 6W6Y) and NSP5 (PDB ID: 6M2N) receptors using Molegro Virtual Docker (MVD) 6.0. The results showed the predictions of physicochemical properties of the (-)-epigallocatechin (EGC), (-)-epicatechin-3-gallate (ECG), and (-)-epicatechin (EC) compounds fulfilled the five rules of Lipinski's. Catechin compounds have toxicity at levels 4 and 6. The activity of catechin compounds on NSP3 (PDB ID: 6W6Y) and NSP5 (PDB ID: 6M2N) receptors indicated that all catechin compounds had inhibitory activity. The best potential activity compound is (-)-epigallocatechin-3-gallate (EGCG) with a rerank score of -102.8200 and -134.1800 Kcal/mol so that EGCG can be recommended as a candidate for the SARS CoV-2 antiviral compound.
