BACKGROUND: Cisplatin (Cis) is a widely used chemotherapeutic drug for treating a variety of cancers, due to its ability to induce cell death in cancer cells significantly. Recently, graphene and its modified nanocomposites have gained much interest in cancer therapy, due to their unique physicochemical properties. The objective of this study was to investigate the combination effect of Cis and a reduced graphene oxide-silver nanoparticle nanocomposite (rGO-AgNPs) in human cervical cancer (HeLa) cells...

The essential oil of fennel (Foeniculum vulgare) is rich in lipophilic secondary metabolites, which can easily cross cell membranes by free diffusion. Several constituents of the oil carry reactive carbonyl groups in their ring structures. Carbonyl groups can react with amino groups of amino acid residues in proteins or in nucleotides of DNA to form Schiff's bases. Fennel essential oil is rich in anise aldehyde, which should interfere with molecular targets in cells. The aim of the present study was to investigate the chemical composition of the essential oil of fennel growing in Tajikistan...

A novel series of hybrid analogues of monastrol-1,3,5-triazine were designed and developed via one-pot synthesis using Bi(NO3)3 as a catalyst. Entire compounds were evaluated for their anticancer activity against HeLa (cervical cancer), MCF-7 (breast cancer), HL-60 (Human promyelocytic leukemia), HepG2 (Hepatocellular carcinoma) and MCF 12A (normal epithelial breast cell line) using MTT assay, where they showed highest inhibitory activity against MCF-7. The molecules were also found to be non-toxic to MCF 12A cells...

The present work aimed to determine the antioxidant and antiproliferative potential of Luffa cylindrica fruits collected at two different maturation stages and to identify and compare their functional components composition. The methanolic extracts of L. cylindrica fruits harvested at 60 to 65 days after seeding (S1) and 85 to 90 days after seeding (S2) were investigated for their antioxidant activity using various assays. Furthermore, the antiproliferative activity of the extracts against HeLa human cervical cancer cells was explored with xCELLigence real time cell analyzer while the effect of the samples on the membrane integrity of the same cell line was assessed using LDH cytotoxicity leakage assay...

Prostate cancer (PCa) is an international health problem and search for its effective treatment is in progress. Punicalagin (PN), polyphenol from pomegranate fruit, is known to exhibit potent anticancer activity in lung, breast and cervical cells. However, there is paucity of information on its effect in PCa. This study evaluated anti-proliferative effects of PN and its effects on extrinsic pathway of apoptosis in PCa cells, and angiogenesis in chicken chorioallantoic membrane (CAM). Antioxidant activities of PN were determined by 2,2-diphenyl-1-picryhydrazyl (DPPH) radical scavenging and inhibition of lipid peroxidation (LPO) methods...

The N-Mannich base of an isoquinoline alkaloid, berberine, bearing substituted benzothiazole moieties was obtained. Novel synthesized analogues were in vitro screened for antioxidant efficacy toward 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) free radicals and in vitro cytotoxicity towards cervical cancer cell lines (HeLa and CaSki), an ovarian cancer cell line (SK-OV-3) and human renal cancer cell line (Caki-2). Cytotoxicity of the compounds toward normal cell lines was examined using the Madin-Darby canine kidney (MDCK) non-cancer cell line...

Cancer is the principal cause of human death and occurs through highly complex processes that involve the multiple coordinated mechanisms of tumorigenesis. A number of studies have indicated that the microalgae extracts showed anticancer activity in a variety of human cancer cells and can provide a new insight in the development of novel anti-cancer therapy. Here, in order to investigate molecular mechanisms of anticancer activity in the Antarctic freshwater microalga, Chloromonas sp., we prepared ethanol extract of Chloromonas sp...

As a part of our continuing program on the synthesis of steroidal heterocycles, it has been prepared a series of novel steroidal pyrimidine derivatives 4-6via TMSCl, steroidal ketones (1c-3c), urea and benzaldehyde. The systems presented here, are novel scaffolds and have not been described before at 6th position of steroidal-6-one (1c-3c). Structural assignment of newly synthesized compounds was performed by DFT/B3LYP calculations as well as spectral and analytical data. The interactions of compounds (4-6) with HSA were studied by fluorescence spectroscopy, DLS, CD and molecular docking, under imitated physiological conditions...

BACKGROUND: Our previous studies showed that fruit methanol extract from Xylopia aethiopica (MEXA) exhibited antiproliferative activity in human cervical cancer cells via the induction of apoptosis. The present study was designed to assess the antiproliferative, antiangiogenic and antioxidant effects of MEXA on prostate cancer (PCa) cells (PC-3 and LNCaP). METHODS: PC-3 and LNCaP cells were cultured and treated with MEXA (10, 50 and 100 μg/mL). The sodium 3'-[1-(phenylaminocarbonyl)-3,4-tetrazolium]-bis (4-methoxy-6-nitro) benzene sulfonic acid hydrate (XTT) and lactate dehydrogenase (LDH) assays were used to evaluate cell viability and cytotoxicity, respectively...

Natural botanical drugs have attracted attention due to their cancer chemopreventive and chemotherapeutic properties in cancer. Punicalagin (PUN) is the major bioactive component of pomegranate peel, and has been shown to have antioxidant, anti-inflammatory, antiviral, antiproliferation and anticancer properties. PUN has been shown to induce apoptosis in several cancer cell lines. The aim of the present study was to investigate the effect of PUN on HeLa human cervical cancer cells in vitro. The viability of the HeLa cells was assessed following treatment with PUN (0, 12...

Alpha-mangostin, a natural xanthonoid, has been reported to possess the anti-cancer property in various types of human cancer. However, its effects and mechanism of α-mangostin in cervical cancer remain unclear. We found that α-mangostin effectively inhibited cell viability, resulted in loss of mitochondrial membrane potential (MMP), release of cytochrome C, increase of Bax, decrease of Bcl-2, and activation of caspase-9/caspase-3 cascade in cervical cancer cells. Alpha-mangostin elevated the contents of reactive oxygen species (ROS) to activate p38...

BACKGROUND: The discovery of the only animal pigment, bilirubin, in the plant Strelitzia nicolai has triggered a vast number of questions regarding bilirubin's formation and its role in the human body. Recent studies have confirmed that bilirubin at certain levels have many medical benefits. Various case studies have revealed that bilirubin is a potent antioxidant. Cervical cancer is one of South Africa's largest womens' health crises. It is estimated that it affects one out of 41 South African women and kills approximately 8 women in the country every day...

The heterodimeric phloroglucinyl pyrone arzanol (Arz) has raised considerable interest because of its antiviral, anti-inflammatory, and antioxidant activity. We have investigated the effect of methylation of the pyrone moiety on the antioxidant activity and cytotoxicity of Arz. This manoeuvre, that left the polyphenolic moiety unscathed, was nevertheless detrimental for antioxidant activity in both the cholesterol thermal degradation- and the Cu(2+)-induced liposome oxidation assays, providing evidence of structure-activity relationships that go beyond the preservation of the polyphenolic pharmacophore...

The abnormal elevation of sulfiredoxin (Srx/SRXN1)-an antioxidant enzyme whose main function is to protect against oxidative stress-has been shown to be closely correlated with the progression of several types of cancer, including human cervical cancer. However, the molecular mechanism by which Srx promotes tumor progression, especially cancer metastasis in cervical cancer, has not been elucidated. Here, we show that Srx expression gradually increases during the progression of human cervical cancer and its expression level is closely correlated with lymph node metastasis...

Green synthesis of silver nanoparticles (AgNPs) has gained great interest as a simple and eco-friendly alternative to conventional chemical methods. In this study, AgNPs were synthesized by using extracts of marine algae Ecklonia cava as reducing and capping agents. The formation of AgNPs using aqueous extract of Ecklonia cava was confirmed visually by color change and their surface plasmon resonance peak at 418 nm, measured by UV-visible spectroscopy. The size, shape, and morphology of the biosynthesized AgNPs were observed by transmission electron microscopy and dynamic light scattering analysis...
