Antiproliferative Activity of Antibiotics through DNA Binding Mechanism: Evaluation and Molecular Docking Studies. Int J Mol Sci 2023; 24:ijms24032563. [PMID: 36768885 PMCID: PMC9916907 DOI: 10.3390/ijms24032563] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 01/24/2023] [Accepted: 01/26/2023] [Indexed: 01/31/2023] Open
Abstract
The antiproliferative activity of three antibiotics clinically use, was studied through DNA inhibition mechanisms, ex vivo, in silico and in vitro. The ex vivo interaction of DNA with ciprofloxacin hydrochloride (CIP·HCl), penicillin G sodium salt (PEN·Na), and tetracycline hydrochloride (TC·HCl) was determined by UV-Vis spectra and viscosity measurements. Furthermore, their binding constants (Kb) toward CT-DNA were calculated (Kb = (2.8 ± 0.6) × 104 (CIP·HCl), (0.4 ± 0.1) × 104 (PEN·Na) and (6.9 ± 0.3) × 104 (TC·HCl) Μ-1). Docking studies on the binding interactions of antibiotics with DNA were performed to rationalize the ex vivo results. The in vitro antiproliferative activity of the antibiotics was evaluated against human breast adenocarcinoma (MCF-7) cells (IC50 values: 417.4 ± 28.2 (CIP·HCl), >2000 (PEN·Na) and 443.1 ± 17.2 (TC·HCl) μΜ). Cell cycle arrest studies confirmed the apoptotic type of MCF-7 cells. The toxicity of the studied agents was in vitro tested against human fetal lung fibroblast cells (MRC-5). The results are compared with the corresponding one for doxorubicin (DOX). Despite their low binding affinity to DNA (Kb) or their different mode of interaction, TC·HCl (anthracycline) or CIP·HCl (quinolones), exhibit notable antiproliferative activity and low toxicity.

Palanivel S, Yli-Harja O, Kandhavelu M. Alkylamino Phenol Derivative Induces Apoptosis by Inhibiting EGFR Signaling Pathway in Breast Cancer Cells. Anticancer Agents Med Chem 2021; 20:809-819. [PMID: 32053080 DOI: 10.2174/1871520620666200213101407] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2019] [Revised: 10/08/2019] [Accepted: 12/30/2019] [Indexed: 11/22/2022]
Abstract
BACKGROUND AND OBJECTIVE The present study was carried out to evaluate the anticancer property of an alkylamino phenol derivative -2-((3,4-Dihydroquinolin-1(2H)-yl)(p-tolyl)methyl)phenol) (THTMP) against human breast cancer cells. The cytotoxicity of the THTMP was assessed to know its specificity towards breast cancer cells without affecting the normal cells. METHODS The THTMP was synthesized and the cytotoxicity was assessed by MTT assay, Caspases enzyme activity, DNA fragmentation and FITC/Annexin V, AO/EtBr staining, RT-PCR and QSAR. In addition, ADME analysis was executed to understand the mode of action of THTMP. RESULTS THTMP showed potential cytotoxic activity against the growth of MCF7 and SK-BR3 cells with the IC50 values of 87.92μM and 172.51μM, respectively. Interestingly, THTMP found to activate caspase 3 and caspase 9 enzymes in cancer cells, which are the key enzymes implicated in apoptosis. THTMP induced apoptosis in which 33% of the cells entered the late apoptotic stage after 24h of treatment. The results also revealed that the apoptotic response could be influenced by the association of THTMP with the Epidermal Growth Factor Receptor (EGFR) mediated inhibition of the Phosphatidylinositol 3-Kinase (PI3K)/S6K1 signaling pathway. In addition, docking was performed to study the binding mode of the THTMP, which shows better interaction with EGFR. The structural elucidation of THTMP by Quantitative Structure-Activity Relationship model (QSAR) and ADMET screening suggested, THTMP as an effective anticancer compound. CONCLUSION This work strengthens the potential of a promising drug-like compound, THTMP, for the discovery of anticancer drug against breast cancer.

Abstract
Breast cancer is the most common cancer that majorly affects female. The present study is focused on exploring the potential anticancer activity of 2-((1, 2, 3, 4-Tetrahydroquinolin-1-yl) (4 methoxyphenyl) methyl) phenol (THMPP), against human breast cancer. The mechanism of action, activation of specific signaling pathways, structural activity relationship and drug-likeness properties of THMPP remains elusive. Cell proliferation and viability assay, caspase enzyme activity, DNA fragmentation and FITC/Annexin V, AO/EtBr staining, RT-PCR, QSAR and ADME analysis were executed to understand the mode of action of the drug. The effect of THMPP on multiple breast cancer cell lines (MCF-7 and SkBr3), and non-tumorigenic cell line (H9C2) was assessed by MTT assay. THMPP at IC50 concentration of 83.23 μM and 113.94 μM, induced cell death in MCF-7 and SkBr3 cells, respectively. Increased level of caspase-3 and -9, fragmentation of DNA, translocation of phosphatidylserine membrane and morphological changes in the cells confirmed the effect of THMPP in inducing the apoptosis. Gene expression analysis has shown that THMPP was able to downregulate the expression of PI3K/S6K1 genes, possibly via EGFR signaling pathway in both the cell lines, MCF-7 and SkBr3. Further, molecular docking also confirms the potential binding of THMPP with EGFR. QSAR and ADME analysis proved THMPP as an effective anti-breast cancer drug, exhibiting important pharmacological properties. Overall, the results suggest that THMPP induced cell death might be regulated by EGFR signaling pathway which augments THMPP being developed as a potential candidate for treating breast cancer.

Abstract
Introduction: Pereskia bleo is a leafy and edible plant, locally known as "Pokok Jarum Tujuh Bilah" which has anticancer properties. This study purposed to determine the cytotoxic effects of P. bleo leaves extracts on several well-known cancer cells and elucidate its underlying mechanism in inducing cell death.Methods: Cytotoxic activity on selected cell lines was determined using MTT assay. Mechanism of cell death was investigated through cell cycle and Annexin V assay. Expression of apoptotic proteins was measured by flow cytometry method.Results: Ethyl acetate extract of P. bleo leaves (PBEA) appeared to have the strongest IC50 value (14.37 ± 8.40 μg/ml) and most active against HeLa cells was further studied for apoptosis. The cell cycle investigation by flow cytometry evidenced the increment of PBEA treated HeLa cells in G0/G1 phase and apoptotic event was detected in Annexin V assay. Analysis of apoptotic protein showed pro-apoptotic proteins (Bax, p53 and caspase 3) were triggered where as anti-apoptotic protein Bcl-2 was suppressed in treated HeLa cells.Conclusions: Our findings demonstrated that PBEA treatment induced cell death in HeLa cells by p53-mediated mechanism through arresting cell cycle at G0/G1 phase and mitochondrial-mediated pathway with involvement of pro-apoptotic proteins, anti-apoptotic protein, and caspase 3.

Abstract
BACKGROUND The exploration of the plant biodiversity as a natural source to obtain sustainable food products and new bioactive pharmaceutical compounds has been growing significantly due to their abundance, safety and economy. Natural pharmaceutical and edible compounds present some advantages when compared to synthetic ones, such as being chemically inert and widely available. In this sense, plants of the genus Pereskia belonging to the Cactaceae family, have been studied. It is an unconventional wild edible plant that contains a large amount of protein and minerals. Studies have demonstrated their biological activities and potential application in different areas such as pharmaceutical, medicinal and food. OBJECTIVE This review is focused on the chemical composition, functional properties, applications on pharmaceutical, nutraceutical and food areas and formulation techniques to enhance the stability and bioavailability of bioactive compounds from the underutilized wild edible plant known as ora-pro-nobis (Pereskia aculeata or Pereskia grandifolia). CONCLUSION The latest studies involving ora-pro-nobis demonstrated its great potential due to its biological activities, which could stimulate further investigations. The utilization of this plant as a natural source to supplement the diet, or to prepare new food products and pharmaceutical formulations is an attractive approach to explore and fully realize the potential of the rich biodiversity found in Brazil and in other countries.

Abstract
Copao (Eulychnia acida Phil., Cactaceae) is an endemic species occurring in northern Chile. The edible fruits of this plant are valued for its acidic and refreshing taste. Phenolic-enriched extracts from copao fruit pulp and epicarp, collected in the Elqui and Limari river valleys, were assessed by its in vitro ability to inhibit the pro-inflammatory enzymes lipoxygenase (LOX) and cyclooxygenases (COX-1 and COX-2). At 100 μg/mL, pulp extracts showed better effect towards LOX than epicarp extract, while COX-2 inhibition was observed for both epicarp and pulp samples. In general, the extracts were inactive towards COX-1. A positive correlation was observed between the anti-inflammatory activity and the main phenolic compounds found in this fruit. Copao fruits from the Limari valley, a main place of collection and commercialization, showed major activity, adding evidence on the possible health-beneficial effects of this native Chilean fruit.

Abstract
Pereskia bleo, a leafy cactus, is a medicinal plant native to West and South America and distributed in tropical and subtropical areas. It is traditionally used as a dietary vegetable, barrier hedge, water purifier, and insect repellant and for maintaining health, detoxification, prevention of cancer, and/or treatment of cancer, hypertension, diabetes, stomach ache, muscle pain, and inflammatory diseases such as dermatitis and rheumatism. The aim of this paper was to provide an up-to-date and comprehensive review of the botanical characteristics, traditional usage, phytochemistry, pharmacological activities, and safety of P. bleo. A literature search using MEDLINE (via PubMed), Science direct, Scopus and Google scholar and China Academic Journals Full-Text Database (CNKI) and available eBooks and books in the National University of Singapore libraries in English and Chinese was conducted. The following keywords were used: Pereskia bleo, Pereskia panamensis, Pereskia corrugata, Rhodocacus corrugatus, Rhodocacus bleo, Cactus panamensis, Cactus bleo, Spinach cactus, wax rose, Perescia, and Chinese rose. This review revealed the association between the traditional usage of P. bleo and reported pharmacological properties in the literature. Further investigation on the pharmacological properties and phytoconstituents of P. bleo is warranted to further exploit its potentials as a source of novel therapeutic agents or lead compounds.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Local communities in Malaysia consume Pereskia bleo Kunth. (Cactaceae) leaves as raw vegetables or as a concoction and drink as a tea to treat diabetes, hypertension, rheumatism, cancer-related diseases, inflammation, gastric pain, ulcers, and for revitalizing the body. AIM OF THE STUDY To evaluate anti-nociceptive activity of the extracts and vitexin, isolated for the first time in this species, in two analgesic models; formalin-induced licking and acetic acid-induced abdominal writhing. MATERIALS AND METHODS Three and a half kilos of P. bleo leaves were extracted using Soxhlet apparatus with ethanol for 72 h. The crude ethanol extract was treated with activated charcoal overnight and subjected to a liquid-liquid partition yielding hexane, dichloromethane, ethyl acetate and butanol extracts. All extracts, including the crude ethanol and vitexin isolated from the ethyl acetate partition were tested for peripheral anti-nociceptive activity using formalin test and acetic acid-induced abdominal writhing, besides having their acute toxicity assays performed. RESULTS The phytochemical analyses resulted in the isolation of vitexin (1), β-sitosterol glucoside (2) and β-sitosterol (3) isolated from the ethyl acetate, dichloromethane and hexane extracts, respectively. This is the first time vitexin and β-sitosterol glucoside are isolated from this species. The anti-nociceptive activities for all extracts were only moderate. Vitexin, which was isolated from the ethyl acetate extract did not show any activity in all models tested when used alone at the same concentration as it appears in the extract. CONCLUSION This study showed that all the extracts possess moderate anti-nociceptive activity. Vitexin is not the compound responsible for the anti-nociceptive effect in the ethyl acetate extract. Further investigations are needed to identify the compound(s) that might be responsible for the anti-nociceptive activity in this plant.
