One of the targets of breast anticancer receptors is the HER-2 protein. This research aims to determine the anticancer activity, the toxicity of the compound, and the prediction of physicochemical properties of flavonoids contained in Citrus maxima through in silico approach. Flavonoid compounds were screened using SwissADME with Lipinski's rule of five, Torsion, TPSA, and P-Gp Non-Substrate. Compounds that passed the screening were carried out molecular docking to the HER-2 receptor (PDB ID: 3PP0) using the Molegro Virtual Docker (MVD). The HER-2 receptor (GDP ID: 3PP0) was declared valid because it had RMSD<2Å. The results showed that there were 11 flavonoid compounds that passed the screening and had a lower rerank score than the comparison compound Trastuzumab. Toxicity was predicted using the Protox II online tool and the results showed that the flavonoid compounds were in the safe limits, namely classes 5 and 3. Based on this research, it can be concluded that acacetin, diosmetin, honyucitrin, isosinensetin, nobiletin, sinensetin, and tangeretin can be candidates for breast cancer drugs based on natural ingredients.Keywords: breast cancer, Citrus maxima, HER-2, in silico.","PeriodicalId":32620,"journal":{"name":"ISCC Indonesian Journal of Cancer Chemoprevention","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80197031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Citrus peels are rich of phytochemical compounds, especially citrus flavonoids, that possess cytotoxic activities. This study aimed to determine the potential of citrus flavonoids as chemopreventive agents targeting GGPS1 protein by phytochemical and bioinformatic studies. Dried peels of Citrus reticulata were extracted by hydrodynamic-cavitation method followed by identification of compounds using thin layer chromatography (TLC). The expression level of GGPS1 was obtained from UALCAN, while its correlation with survival rate was obtained from the GEPIA. Prediction models regarding the potential inhibitors of citrus peel compounds against GGPS1 were obtained through KNIME and ChEMBl, followed by literature studies on chemopreventive activity of citrus flavonoids. The molecular docking was used to predict the molecular interaction followed by tracking of target genes that were positively correlated with GGPS1 by SwissTargetPrediction. Yielded 75% (v/v), the extract positively contained citrus flavonoid with hesperidin as comparison. Overexpression of GGPS1 significantly reduced the survival rate of liver cancer patients (p value=0.019). Four citrus flavonoid compounds, namely tangeretin, nobiletin, hesperidin, and naringenin showed potential inhibition to GGPS1. The molecular docking showed that tangeretin had a strong affinity compared to the native ligand and zoledronic acid, as positive control. PARP1, CSNK2A1, TNKS2, and GSK3B were clarified as targeted genes for tangeretin and nobiletin that positively correlated with GPPS1.

Previously, we reported that naringenin and hesperidin, the abundant flavanons in citrus fruit peel, increased cytotoxic and apoptosis activities of doxorubicin in doxorubicin resistant breast cancer cells (T47D and MCF-7 cells). Since doxorubicin arrests G2/M phase in most cancer cells, both flavanons are speculated to affect the similar phase in breast cancer cells. Cell cycle distributions were determined by flowcytometry using propidium iodide (PI) to stain DNA of the cells. Combination of naringenin or hesperidin with doxorubicin increased accumulation of T47D cells in G2/M phase, while in MCF-7 cells, accumulated cells in G2/M phase were decreased, accompanying with slightly increased in G1 phase. Naringenin itself had no effect on cell cycle of both cells. Whereas, hesperidin arrested G2/M and G1 phases in T47D and MCF-7 cells, respectively. The different effect of naringenin and hesperidin in T47D and MCF-7 cells is most likely caused by difference of p53 status. In p53 mutant, T47D cells, naringenin and hesperidin supported mechanism of doxorubicin to arrest at G2/M that to be considered via p53-independent pathway. Whereas, in p53 wild-type MCF-7 cells, naringenin and hesperidin decreased G2/M arrest, suggesting that both flavanons do not utilize cell cycle arrest for their anticancer activity with doxorucibin.
