ABSTRACT: The multidrug resistance associated include the active extrusion of xenobiotics by commonly proteins (MRP1, MRP2, MRP3, MRP4, MRP5, shared transport proteins, mainly located in kidney, MRP6, MRP7, MRP8 and MRP9) belongs to the liver and intestine. The ATP-binding cassette (ABC) ATP-binding cassette superfamily (ABCC family) superfamily of transporters consist of a large number of transporters expressed differentially in the liver, of functionally diverse transmembrane proteins which kidney, intestine and blood-brain barrier. MRPs have been subdivided into seven families designated A transport a structurally diverse array of endo- and through G (1-4). Members of this transport superfamily xenobiotics and their metabolites (in particular display high amino acid similarity of the 200 amino acids conjugates) and are subject to induction and surrounding the ATP-binding folds.

  • Cinobufagin, a Bufadienolide, Activates ROS-Mediated Pathways to Trigger Human Lung Cancer Cell Apoptosis in Vivo
    RSC Advances View Article Online PAPER View Journal | View Issue Cinobufagin, a bufadienolide, activates ROS- mediated pathways to trigger human lung cancer Cite this: RSC Adv.,2017,7,25175 cell apoptosis in vivo† Panli Peng, ab Junhong Lv,c Changqing Cai,b Shaohuan Lin,c Enqing Zhuob and Senming Wang*a Lung cancer, as the most common malignancy worldwide, is one of the most threatening diseases for human beings. Chan Su, an ethanolic extract from skin and parotid venom glands of the Bufo bufo gargarizans Cantor, is widely used as a traditional Chinese medicine in cancer therapy. Bufadienolides are cardiotonic steroids isolated from the skin and parotid venom glands of toad Bufo bufo gargarizans Cantor with excellent anticancer activity. Unfortunately, little information about the in vivo effects and action mechanisms of bufadienolides on human lung cancer cells is available. Therefore, in this study, the anticancer activities of Cinobufagin (CnBu), bufalin (Bu) and arenobufagin (ArBu) were evaluated in Creative Commons Attribution 3.0 Unported Licence. vivo and in vitro and the underlying mechanisms were elucidated. The results showed that CnBu exhibited higher anticancer efficacy than Bu and AuBu against a panel of five lung cancer cells (A549, NCI-H460, H1299, Sk-mes-1 and Calu-3) with IC50 values ranging from 2.3–6.7 mM. Moreover, CnBu showed much higher selectivity between cancer and normal cells, as suggested by its IC50 value towards BEAS-2B human normal bronchial epithelial cells reaching 22.3 mM. CnBu also significantly inhibited the growth of A549 cells in a dose-dependent manner through anti-migration and anti-invasion.

It possesses significant antineoplastic activity in vitro. Although bufadienolide has been found to disrupt the cell cycle, the underlying mechanisms of this disruption are not defined. Here, we reported that arenobufagin blocked the transition from G2 to M phase of cell cycle through inhibiting the activation of CDK1-Cyclin B1 complex; The tumor suppressor p53 contributed to sustaining arrest at the G2 phase of the cell cycle in hepatocellular carcinoma (HCC) cells. Moreover, arenobufagin caused double-strand DNA breaks (DSBs) and triggered the DNA damage response (DDR), partly via the ATM/ATR-Chk1/Chk2-Cdc25C signaling pathway. Importantly, we used a synthetic biotinylated arenobufagin-conjugated chemical probe in live cells to show that arenobufagin accumulated mainly in the nucleus.

  • Toxins of Animals) [Biological-Origin Toxins]
    4: Zootoxins (toxins of animals) [Biological-origin toxins] Distinction should be made between poisonous animals – those with toxins in their skin or other organs and which are toxic on ingestion – and venomous animals – those with specialised structures for production and delivery of toxins (venoms) to prey species or adversaries. Halstead (1988) published a monumental review of poisonous and venomous marine animals. A world list of snake venoms and other animal toxins including bee venoms, sawfly toxins, amphibian and fish toxins has been compiled by Theakston & Kamiguti (2002). Animals acquire toxins by one of three methods (Mebs 2001): • expression of genes coding for the toxin structures • metabolic synthesis (production of secondary metabolites) • uptake, storage and sequestration of toxins produced by other organisms (microbes, plants, or other animals) References: Halstead BW (1988) Poisonous and Venomous Marine Animals of the World. 2nd revised edition.

  • Occurrence of Marinobufotoxin and Telocinobufotoxin Homologs in the Skin of Bufo Bankorensis Borbour1) KAZUTAKE SHIMADA, YOSHI
    2300 Vol. 35 (1987) Chem. Pharm. Bull. 35( 6 )2300-2304(1987), Occurrence of Marinobufotoxin and Telocinobufotoxin Homologs in the Skin of Bufo bankorensis BORBOuR1) KAZUTAKESHIMADA, YOSHIHIRO SATO, and TOSHIONAMBARA* PharmaceuticalInstitute, Tohoku University, Aobayama, Sendai 980, Japan (ReceivedNovember 13, 1986) The occurrenceof marinobufagin3-succinyl-L-arginine and 3-glutaryl-L-arginineesters, and telocinobufagin3-glutaryl-L-arginine ester, together with seven known bufogenins, in the skinof Bufo bankorensisBORBOUR, is reported. The structureswere elucidatedby degradativemeans and/ordirect comparisonwith authenticsamples. These compounds were assayed for inhibitory activitytowards guinea pig heart Na+, K+-adenosine triphosphatase. Keywords-Bufo bankorensis;toad venom; bufogenin;marinobufotoxin homolog; telo- cinobufotoxinhomolog; sodium-potassium-activated ATPase inhibition In a series of studies on toad venom,2) we characterized the cardiac steroids in the skin of Formosan toad, Bufo bankorensis BORBOUR, and assayed them for Na +-adenosine triphosphatase (Na+, K +-ATPase; EC 3.6.1.3) inhibitory activity.3) Five toads were sacrificed by freezing in dry ice, and the skins were immediately flayed off and extracted with ethanol. The ethanolic extract was concentrated in vacuo and the residue was subjected to column chromatography on silica gel. Subsequent separation of the bufogenin and bufotoxin mixture was repeatedly done by high-performance liquid chromat- ography (HPLC) on a reversed-phase column. Three new bufotoxins (5a, 5b, 10) were isolated as colorless amorphous substances, which gave negative ninhydrin and positive Sakaguchi tests. Upon hydrolysis with 6 N hydrochloric acid, arginine was produced and identified by thin-layer chromatography (TLC). When subjected to enzymic hydrolysis with a hog pancreas lipase preparation followed by methylation with diazomethane, these bufotoxins afforded bufogenin 3-hemi- carboxylate methyl esters (3a, 3b, 8).
