[PMID: 39321861 DOI: 10.1016/j.cbi.2024.111254] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2024] [Revised: 09/19/2024] [Accepted: 09/23/2024] [Indexed: 09/27/2024]
Abstract
Breast and lung cancers are the leading causes of cancer-related deaths in the world. Although considerable progress has been made in the field of cancer therapy, quest to discover potent, safe and cost-effective alternatives especially from natural sources is being pursued. Snake venom, which is a treasure trove of various peptides and proteins including natural toxins that specifically target tissues and receptors in the envenomated victims. Many such proteins are being explored for their therapeutic potential against various diseases including cancers. Here, we report the mechanism of cytotoxic activity of crude venom and a purified protein, Cytotoxin from the monocled cobra (Naja kaouthia), an elapid snake with neurotoxic venom prominently found in the North-East India. The crude venom showed significant cytotoxicity against breast (MCF-7and MDA-MB-231) and lung (A549, NCI-H522) cancer cell lines. Bioassay-guided fractionation using RP-HPLC showed highest cytotoxic activity in peak P9. Liquid chromatography-tandem mass spectrometry (ESI-LC-MS/MS) analysis was employed and the fraction is identified as Cytotoxin 10 which showed comparable cytotoxicity against the experimental cell lines. Cytotoxin 10 also exhibited apoptosis in MCF-7 and A549 cell lines using AO/EtBr and flow cytometry analysis. Expressions of apoptosis related proteins e.g. Bax, Bcl-2, Caspase-7 and PARP were also studied following Cytotoxin 10 treatment in both cell lines. Molecular docking experiments performed to investigate the interactions between Cytotoxin 10 and the apoptotic proteins revealed favourable binding scores compared to their corresponding inhibitors. Interestingly, Cytotoxin 10 inhibited migration and adhesion in a time and dose-dependent manner in both MCF-7 and A549 cells. This is the first report elucidating the mechanism of cytotoxic activity of Cytotoxin 10 purified from Naja kaouthia venom of North-East India origin and could pave the way for development of potential therapeutic strategies against breast and lung cancer.

Abstract
Green synthesis of iron oxide nanoparticles using plant extracts is of tremendous interest owing to its cost effectiveness, ecofriendly and high efficiency compared to physical and chemical approaches. In the current study, we describe a green approach for producing iron oxide nanoparticles utilizing Polyalthia korintii aqueous leaf extract (PINPs). The prepared PINPs were assessed of their biological and dye degradation potentials. The physico-chemical characterization of PINPs using UV-Visible spectrophotometer, Fourier Transform Infrared Spectroscopy, X-Ray Diffraction studies, Field emission Scanning Electron Microscopy and Energy Dispersive X-ray spectroscopy analysis confirmed the synthesized sample comprised of iron oxide entity, predominantly spherical with the size range of 40-60 nm. Total Phenolic Content of PINPs is 59.36 ± 1.64 µg GAE/mg. The PINPs exhibited 89.78 ± 0.07% DPPH free radical scavenging and 28.7 ± 0.21% ABTS cation scavenging activities. The antibacterial activities were tested against different gram-positive and gram-negative bacteria and PINPs were more effective against Enterococcus faecalis and Klebsiella pneumoniae. Cytotoxicity of PINPs against K562 and HCT116 were measured and IC50 values were found to be 84.99 ± 4.3 µg/ml and 79.70 ± 6.2 µg/ml for 48 h respectively. The selective toxicity of PINPs was demonstrated by their lowest activity on lymphocytes, HEK293 cells, and erythrocytes. The toxicity (LC 50 values) against first, second, third and fourth instar larvae of Culex quinquefasciatus was 40 ± 1.5 mg/mL, 45 ± 0.8 mg/mL, 99 ± 2.1 mg/mL and 120 ± 3.5 mg/mL respectively. Finally, PINPs were utilized to as a catalyst for removal of textile dyes like Methylene blue and methyl orange in a fenton-like reaction. The results showed 100% dye degradation efficiency in a fenton like reaction within 35 min. Thus, the green synthesized PINPs exhibit antioxidant, antibacterial, antiproliferative, larvicidal and dye degradation potentials, indicating their suitability for biological and environmental applications.

Abstract
Snake venom contains a cocktail of compounds dominated by proteins and peptides, which make up the toxin. The toxin components of snake venom attack several targets in the human body including the neuromuscular system, kidney and blood coagulation system and cause pathologies. As such, the venom toxins can be managed and used for the treatment of these diseases. In this regard, Captopril used in the treatment of cardiovascular diseases was the first animal venom toxin-based drug approved by the US Food and Drug Administration and the European Medicines Agency. Cancers cause morbidity and mortality worldwide. Due to side effects associated with the current cancer treatments including chemotherapy, radiotherapy, immunotherapy, hormonal therapy and surgery, there is a need to improve the efficacy of current treatments and/or develop novel drugs from natural sources including animal toxin-based drugs. There is a long history of earlier and ongoing studies implicating snake venom toxins as potential anticancer therapies. Here, we review the role of crude snake venoms and toxins including phospholipase A2, L-amino acid oxidase, C-type lectin and disintegrin as potential anticancer agents tested in cancer cell lines and animal tumour models in comparison to normal cell lines. Some of the anti-tumour activities of snake venom toxins include induction of cytotoxicity, apoptosis, cell cycle arrest and inhibition of metastasis, angiogenesis and tumour growth. We thus propose the advancement of multidisciplinary approaches to more pre-clinical and clinical studies for enhanced bioavailability and targeted delivery of snake venom toxin-based anticancer drugs.

JOURNAL OF ETHNOPHARMACOLOGY 2024; 323:117671. [PMID: 38163555 DOI: 10.1016/j.jep.2023.117671] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Revised: 12/23/2023] [Accepted: 12/26/2023] [Indexed: 01/03/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Snake bites are a critical health issue in many parts of the world particularly in Asian countries lacking efficient health facilities in rural areas. Cobra is the most common snake type in Asia and is responsible for a large number of mortalities particularly in rural areas. Plants are usually considered the most effective and easy-to-approach treatment for snake bites in rural areas of various countries. Vitex negundo L. is an important medicinal plant traditionally used to treat snake bite envenomation in many countries of Asia. AIM OF THE STUDY From literature survey of plants traditionally used in the treatment of snake bites in Asian countries including India, Pakistan and Sri Lanka, roots of V. negundo were selected for the present study. Anti-snake venom potential of its roots was assessed through various in vitro assays targeting the phospholipase A2 enzyme. MATERIALS AND METHODS V. negundo roots were sequentially extracted in different organic solvents to get fractions and in methanol to get total extract. The extracts were evaluated for phospholipase A2 (PLA2) inhibitory potential through inhibition of venom-induced hemolysis, ADP-induced platelet aggregation, PLA2-induced fatty acid hydrolysis and anticoagulant effect of cobra venom. Antioxidant power was determined using DPPH and superoxide radical scavenging assays. GC-MS and HPLC analysis was performed for the total methanol extract. RESULTS Strong PLA2 inhibitory effect was observed for all the extracts. The ethyl acetate, acetone and methanol fractions significantly inhibited toxic effects of cobra venom under in vitro conditions. Radical scavenging potential of these fractions was also significantly high as compared to non-polar fractions in both DPPH and superoxide scavenging assays. Phytochemical analysis indicated high phenolic and flavonoid contents in these fractions. GC-MS and HPLC analysis of total methanol extract confirmed the presence of bis(2-ethylhexyl) phthalate, phenol, o-Guaiacol, palmitic acid-methyl ester, methyl stearate, quercetin and kaempferol in the plant. CONCLUSION The study concluded that the roots of V. negundo, particularly their polar extracts, have strong PLA2 inhibitory effect against cobra venom confirming their traditional use to manage snake bites. The roots of this plant can be further studied for isolation of plant-based antisera.

Abstract
Little is known of the biochemical composition and functional features of the venoms of poorly known Colombian coral snakes. Here, we provide a preliminary characterization of the venom of two Colombian endemic coral snake species, Micrurus medemi and M. sangilensis, as well as Colombian populations of M. helleri. Electrophoresis and RP-HPLC techniques were used to identify venom components, and assays were conducted to detect enzyme activities, including phospholipase A2, hyaluronidase, and protease activities. The median lethal dose was determined using murine models. Cytotoxic activities in primary cultures from hippocampal neurons and cancer cell lines were evaluated. The venom profiles revealed similarities in electrophoretic separation among proteins under 20 kDa. The differences in chromatographic profiles were significant, mainly between the fractions containing medium-/large-sized and hydrophobic proteins; this was corroborated by a proteomic analysis which showed the expected composition of neurotoxins from the PLA2 (~38%) and 3FTx (~17%) families; however, a considerable quantity of metalloproteinases (~12%) was detected. PLA2 activity and protease activity were higher in M. helleri venom according to qualitative and quantitative assays. M. medemi venom had the highest lethality. All venoms decreased cell viability when tested on tumoral cell cultures, and M. helleri venom had the highest activity in neuronal primary culture. These preliminary studies shed light on the venoms of understudied coral snakes and broaden the range of sources that could be used for subsequent investigations of components with applications to specific diseases. Our findings also have implications for the clinical manifestations of snake envenoming and improvements in its medical management.

Abstract
Snake venom disintegrins are low molecular weight, non-enzymatic proteins rich in cysteine, present in the venom of snakes from the families Viperidae, Crotalidae, Atractaspididae, Elapidae, and Colubridae. This family of proteins originated in venom through the proteolytic processing of metalloproteinases (SVMPs), which, in turn, evolved from a gene encoding an A Disintegrin And Metalloprotease (ADAM) molecule. Disintegrins have a recognition motif for integrins in their structure, allowing interaction with these transmembrane adhesion receptors and preventing their binding to proteins in the extracellular matrix and other cells. This interaction gives disintegrins their wide range of biological functions, including inhibition of platelet aggregation and antitumor activity. As a result, many studies have been conducted in an attempt to use these natural compounds as a basis for developing therapies for the treatment of various diseases. Furthermore, the FDA has approved Tirofiban and Eptifibatide as antiplatelet compounds, and they are synthesized from the structure of echistatin and barbourin, respectively. In this review, we discuss some of the main functional and structural characteristics of this class of proteins and their potential for therapeutic use.

Pharmacological Screening of Venoms from Five Brazilian Micrurus Species on Different Ion Channels. Int J Mol Sci 2022; 23:ijms23147714.

Abstract
Coral snake venoms from the Micrurus genus are a natural library of components with multiple targets, yet are poorly explored. In Brazil, 34 Micrurus species are currently described, and just a few have been investigated for their venom activities. Micrurus venoms are composed mainly of phospholipases A2 and three-finger toxins, which are responsible for neuromuscular blockade—the main envenomation outcome in humans. Beyond these two major toxin families, minor components are also important for the global venom activity, including Kunitz-peptides, serine proteases, 5′ nucleotidases, among others. In the present study, we used the two-microelectrode voltage clamp technique to explore the crude venom activities of five different Micrurus species from the south and southeast of Brazil: M. altirostris, M. corallinus, M. frontalis, M. carvalhoi and M. decoratus. All five venoms induced full inhibition of the muscle-type α1β1δε nAChR with different levels of reversibility. We found M. altirostris and M. frontalis venoms acting as partial inhibitors of the neuronal-type α7 nAChR with an interesting subsequent potentiation after one washout. We discovered that M. altirostris and M. corallinus venoms modulate the α1β2 GABAAR. Interestingly, the screening on KV1.3 showed that all five Micrurus venoms act as inhibitors, being totally reversible after the washout. Since this activity seems to be conserved among different species, we hypothesized that the Micrurus venoms may rely on potassium channel inhibitory activity as an important feature of their envenomation strategy. Finally, tests on NaV1.2 and NaV1.4 showed that these channels do not seem to be targeted by Micrurus venoms. In summary, the venoms tested are multifunctional, each of them acting on at least two different types of targets.

Abstract
A bioinspired chitosan/vitamin E conjugate (Ch/VES, 1:4) was synthesized, optimized based on chitosan's molecular weight (15, 300 kDa), and was assembled to entrap oxaliplatin (OXPt). 1H NMR, infrared spectroscopy, chromatography, X-ray photoelectron spectroscopy, X-ray diffraction, drug release, hemolysis, and stability studies were performed to characterize OXPt@Ch/VES micelles. The therapeutic efficacy of the micelles was tested in vitro in ER+/PR+/HER2- and triple-negative sensitive/resistant breast cancer cells, MCF-7 and MDA-MB-231 via cellular uptake, cytotoxicity, nuclear staining, DNA fragmentation, mitochondrial membrane potential, ROS generation, apoptosis, and cell cycle assays and in vivo using 4T1(Luc)-tumor-bearing mice. OXPt@Ch/VES Ms exhibited decreased IC50 towards MCF-7, MDA-MB-231 (sensitive/resistant) than OXPt. OXPt@Ch/VES Ms caused extensive DNA damage, mitochondrial depolarization, apoptosis, and cell-growth arrest (G2/M). OXPt@Ch/VES Ms treatment retarded tumor growth significantly, prolonged survival, and decreased nephrotoxicity than OXPt. The OXPt@Ch/VES Ms could serve as a potential nanomedicine to overcome conventional OXPt-mediated drug resistance/nephrotoxicity in breast cancer.

Abstract
This study demonstrates a simple protocol for phytofabrication of titanium dioxide nanoparticles (TiO2NPs) wrapped with bioactive molecules from Ludwigia octovalvis leaf extract and their characterization by UV-visible absorption spectroscopy, Fourier transform spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), X-ray photoelectron spectrum (XPS), and diffuse reflectance spectrum (DRS). The bandgap energy of pure green engineered TiO2 nanoparticles was determined by DRS analysis. The XPS analysis confirmed the purity of the TiO2 nanoparticles. Results show that the synthesized TiO2NPs were spherical in shape with the size ranged from 36 to 81 nm. The green engineered titanium oxide nanocatalyst exhibited enhanced rate of photocatalytic degradation of important textile toxic dyes namely crystal violet (93.1%), followed by methylene blue (90.6%), methyl orange (76.7%), and alizarin red (72.4%) after 6-h exposure under sunlight irradiation. Besides, this study determines the antimicrobial efficiency of TiO2NPs (25 μl and 50 μl), leaf extract (25 μl), and antibiotic (25 μl) against clinically isolated human pathogenic bacterial strains namely Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa, Proteus vulgaris, Staphylococcus epidermidis, and Escherichia coli. Results show that maximum antibacterial activity with nanotitania treatment noticed was 21.6 and 18.3-mm inhibition in case of S. epidermis and P. aeruginosa, respectively. Enhanced rate of antibiofilm activity towards S. aureus and K. pneumoniae was also observed with TiO2NPs exposure. The biomolecule loaded TiO2NPs exhibited the fastest bacterial deactivation dynamics towards gram-negative bacteria (E. coli), with a complete bacterial inactivation within 105-min exposure. Interestingly, anticancer activity result indicates that percentage of human cervical carcinoma cell (HeLa) viability was negatively correlated with TiO2NPs doses used. The AO/EtBr fluorescent staining result exhibited the occurrence of more apoptosis (dead cells) of HeLa cells due to the exposure of TiO2NPs. Altogether, the present study clearly showed that biomolecules wrapped nanotitania could be used as effective and promising compound for enhanced photocatalytic and biomedical applications in the future.

Abstract
Snake venoms are a potential source of various enzymatic and non-enzymatic compounds with a defensive role for the host. Various peptides with significant medicinal properties have been isolated and characterized from these venoms. Few of these are FDA approved. They inhibit tumor cells adhesion, migration, angiogenesis and metastasis by inhibiting integrins on transmembrane cellular surfaces. This plays important role in delaying tumor growth, neovascularization and development. Tumor targeting and smaller size make them ideal candidates as novel therapeutic agents for cancer treatment. This review is based on sources of these disintegrins, their targeting modality, classification and underlying anti-cancer potential.

Abstract
The search for novel and relevant cancer therapeutics is continuous and ongoing. Cancer adaptations, resulting in therapeutic treatment failures, fuel this continuous necessity for new drugs to novel targets. Recently, researchers have started to investigate the effect of venoms and venom components on different types of cancer, investigating their mechanisms of action. Receptor tyrosine kinases (RTKs) comprise a family of highly conserved and functionally important druggable targets for cancer therapy. This research exploits the novelty of complex venom mixtures to affect phosphorylation of the epidermal growth factor receptor (EGFR) and related RTK family members, dually identifying new activities and unexplored avenues for future cancer and venom research. Six whole venoms from diverse species taxa, were evaluated for their ability to illicit changes in the phosphorylated expression of a panel of 49 commonly expressed RTKs. The triple negative breast cancer cell line MDA-MB-468 was treated with optimised venom doses, pre-determined by SDS PAGE and Western blot analysis. The phosphorylated expression levels of 49 RTKs in response to the venoms were assessed with the use of Human Phospho-RTK Arrays and analysed using ImageLab 5.2.1 analysis software (BioRad). Inhibition of EGFR phosphorylation occurred with treatment of venom from Acanthoscurria geniculata (Theraphosidae), Heterometrus swammerdami (Scorpionidae), Crotalus durissus vegrandis (Crotalidae) and Naja naja (Elapidae). Western green mamba Dendroaspis viridis venom increased EGFR phosphorylation. Eph, HGFR and HER were the most affected receptor families by venoms. Whilst the importance of these changes in terms of effect on MDA-MB-468 cells' long-term viability and functionality are still unclear, the findings present exciting opportunities for further investigation as potential drug targets in cancer and as tools to understand better how these pathways interact.

Abstract
The unclear bio-safety issue and potential risk of nanoparticles (NPs) on various organelles can be considered as a major challenge. In the present study, we have assessed the green synthesis of ZnO nanoparticles using Hyssop (Hyssopus officinalis) extract and their effects on PC3 cell line and BALB/c mice model. The cytotoxicity of the ZnO-NPs was assessed on PC3 cell line by MTT test after characterisation. Apoptotic effect of ZnO-NPs was determined by in vitro AO/PI staining. The histopathological assessments and determination of LH and FSH levels carried out as in vivo analysis in BALB/c adult male mice. The expression of major genes involved in spermatogenesis and sperm maturation (Adam3, Prm1, Spata19, Tnp2, Gpx5) were also analysed. The obtained result demonstrated that the IC50 for PC3 cell line treated with green-synthesised ZnO-NPs during 24 and 48 hr was reported 8.07 and 5 µg/ml respectively. Meanwhile, the induced apoptosis was recorded 26.6% ± 0.05, 44% ± 0.12 and 80% ± 0.07 of PC3 cells. The results of gene expression analysis revealed that the increase in the concentration of ZnO-NPs significantly (p < .05) down-regulated the Adam3, Prm1, Spata-19, Tnp2 and Gpx5 genes. The overall results of this research elucidated that ZnO-NPs impaired spermatogenesis, sperm maturation process and sperm motility.

Antitumoral Potential of Lansbermin-I, a Novel Disintegrin from Porthidium lansbergii lansbergii Venom on Breast Cancer Cells. Curr Top Med Chem 2019; 19:2069-2078. [DOI: 10.2174/1568026619666190806151401] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2019] [Revised: 06/13/2019] [Accepted: 07/01/2019] [Indexed: 12/31/2022]
Abstract
Background:
Disintegrins from snake venoms bind with high specificity cell surface integrins,
which are important pharmacological targets associated with cancer development and progression.
Objective:
In this study, we isolated a disintegrin from the Porthidium lansbergii lansbergii venom and
evaluated its antitumoral effects on breast cancer cells.
Methods:
The isolation of the disintegrin was performed on RP-HPLC and the inhibition of platelet aggregation
was evaluated on human platelet-rich plasma. The inhibition of cell adhesion was also evaluated
in vitro on cultures of cell lines by the MTT method as well as the inhibition of breast cancer cell
migration by the wound healing assay. The binding of the disintegrin to integrin subunits was verified by
flow cytometry and confocal microscopy. Finally, inhibition of angiogenesis was assessed in vitro on
HUVEC cells and the concentration of VEGF was measured in the cellular supernatants.
Results:
The disintegrin, named Lansbermin-I, is a low molecular weight protein (< 10 kDa) that includes
an RGD on its sequence identified previously. Lansbermin-I showed potent inhibition of ADP and
collagen-induced platelet aggregation on human plasma and also displayed inhibitory effects on the adhesion
and migration of breast cancer MCF7 and MDA-MB 231cell lines, without affecting nontumorigenic
breast MCF-10A and lung BEAS cells. Additionally, Lansbermin-I prevented MCF7 cells to
adhere to fibronectin and collagen, and also inhibited in vitro angiogenesis on human endothelial HUVEC
cells.
Conclusion:
Our results display the first report on the antitumor and anti-metastatic effects of an RGDdisintegrin
isolated from a Porthidium snake venom by possibly interfering with α2 and/or β1-containing
integrins. Thus, Lansbermin-I could be an attractive model to elucidate the role of disintegrins against
breast cancer development.

Abstract
Several countries residing envenomation due to Naja naja had revealed a disparity in the venom composition according to their geographic location and Sri Lankan cobra still lacks the evidence to support this. Therefore, the current study was focused on addressing relationship between the histopathological changes according to geographic variation of Sri Lankan N. naja venom. The histopathological changes in vital organs and muscle tissues following intramuscular administration of venom of N. naja were studied using BALB/c mice. The median lethal dose of venom of N. naja in the present study was determined to be 0.55, 0.66, 0.68, 0.62, and 0.7 mg/kg for North (NRP), Central (CRP), Western, Southern, and Sabaragamuwa Regional Population venoms, respectively. Histopathological changes were observed in different levels in vital organs and muscle tissues of mice. NRP accompanied significantly higher infiltration of inflammatory and necrotic cells into skeletal muscle and CRP venom demonstrated high level of cardiotoxic effects comparing to other regions. This study revealed a certain extent of variations in the pathological effects of N. naja venom samples according to their geographical distribution.

Abstract
Cancer is one of the leading causes of morbidity and mortality worldwide, and the discovery of new drugs for cancer therapy is one of the most important objectives for the pharmaceutical industry. Snake venoms are complex mixtures containing different peptides, proteins, enzymes, carbohydrates and other bioactive molecules, which are secreted by the snake in the predation or defending against threats. Understanding the snake venoms may turn the toxins into a valuable source of new lead compounds in drug discovery. Captopril, the first angiotensin-converting enzyme inhibitor approved in 1981 by FDA, was designed based on the structure of a peptide isolated from the snake venom. The earliest reports about snake venoms used in cancer treatments appeared in the 1930s. Since then, numerous studies on the activities, isolations, purifications and structure elucidations of the components from snake venoms were published. The comprehensive structural and functional investigations of snake venoms would contribute to the development of novel anti-cancer drugs. Our review will focus on the past, present and the future of the studies on snake venoms in cancer target therapy.

Abstract
Viper venom contains antibacterial and cytotoxic components. The aim of this study was to identify and evaluate the antimicrobial and cytotoxic properties of the crude venom of Vipera latifii (V. latifii). Lyophilized venom of V. latifii was quantified by Bradford method and its antibacterial activity (6.25-400 μg/ml) was assessed using the MTT, MIC, Disc diffusion, and Well diffusion assays. Also, its cytotoxic activity was investigated using MTT reduction, Neutral uptake, and Comet assay on human liver cancer (HepG2) cell line. Crude venom showed antibacterial effects against Bacillus subtilis and Staphylococcus aureus, but was not effective on Escherichia coli. Also, the crude venom showed apoptotic and necrotic effects on human liver cancer cells. The venom of V. latifii can inhibit the growth of bacteria and cancer cells. These findings suggest that this may be a potential source of molecules with antibacterial and anticancer characteristics.

Abstract
Ionic liquids (ILs) are much known for their promising alternative for volatile solvents in industries and gained popularity as a greener solvent, however industrial effluent discharge containing ILs are also increasing. There is a scarcity of information on the toxicity of ILs; the present study will explore different facts about their harmfulness. The toxic effects of five different ILs: [C4MIM]Br, [Hx3PC14]N(CN)2, [C10MIM]BF4, [BTDA]Cl and [C4MPY]Cl were analysed on bacteria, fungi, plant and animal cells. Both Gram positive and negative bacteria were found to be more susceptible to [C10MIM]BF4 and [BTDA]Cl than [C4MIM]Br, [Hx3PC14]N(CN)2 and [C4MPY]Cl, whereas fungi revealed quite a resistance to all ILs. All ILs were toxic towards Triticum aestivum affecting their roots and shoots, however [C10MIM]BF4 and [BTDA]Cl were more toxic amongst them. Studies on Allium cepa described their toxic behaviour at the genetic level by altering cell division and nuclear material. Furthermore, studies on human red blood cells described by % haemolysis in which [Hx3PC14]N(CN)2 and [BTDA]Cl exhibited higher toxicity at very lower concentrations. While the genotoxic effect on blood lymphocytes exerted by [Hx3PC14]N(CN)2, [C10MIM]BF4 and [BTDA]Cl confirmed their toxic effects on human cells.

Abstract
The complex venom proteome of the eastern India (EI) spectacled cobra (Naja naja) was analyzed using tandem mass spectrometry of cation-exchange venom fractions. About 75% of EI N. naja venom proteins were <18kDa and cationic at physiological pH of blood. SDS-PAGE (non-reduced) analysis indicated that in the native state venom proteins either interacted with each-other or self-aggregated resulting in the formation of higher molecular mass complexes. Proteomic analysis revealed that 43 enzymatic and non-enzymatic proteins in EI N. naja venom with a percent composition of about 28.4% and 71.6% respectively were distributed over 15 venom protein families. The three finger toxins (63.8%) and phospholipase A2s (11.4%) were the most abundant families of non-enzymatic and enzymatic proteins, respectively. nanoLC-ESI-MS/MS analysis demonstrated the occurrence of acetylcholinesterase, phosphodiesterase, cholinesterase and snake venom serine proteases in N. naja venom previously not detected by proteomic analysis. ATPase, ADPase, hyaluronidase, TAME, and BAEE-esterase activities were detected by biochemical analysis; however, due to a limitation in the protein database depository they were not identified in EI N. naja venom by proteomic analysis. The proteome composition of EI N. naja venom was well correlated with its in vitro and in vivo pharmacological properties in experimental animals and envenomed human. BIOLOGICAL SIGNIFICANCE Proteomic analysis reveals the complex and diverse protein profile of EI N. naja venom which collectively contributes to the severe pathophysiological manifestation upon cobra envenomation. The study has also aided in comprehending the compositional variation in venom proteins of N. naja within the Indian sub-continent. In addition, this study has also identified several enzymes in EI N. naja venom which were previously uncharacterized by proteomic analysis of Naja venom.

Abstract
Lectins are proteins that show a variety of biological activities. Nevertheless, information on lectin from Gluttonous beauts and their anticancer activities are very limited. In this study, we purified a lectin from hemolymph of G. beauts and identified its molecular weight to be 66kDa. The effect of lectin at different concentrations (μg/mL) on the cell growth and apoptosis were evaluated against MCF-7 and MCF-10A cells, whereas cytotoxicity to the MCF-7 cells mediated by lectin was observed and the mechanism of action of the lectin in including apoptosis in cancer cells via the intrinsic pathway was also proposed. The MCF-7 cells were employed for in vitro studies on cytotoxicity, induction of apoptosis and apoptotic DNA fragmentation. In MCF-10A cells lectin did not show any adverse effect even at higher concentration. Cell cycle analysis also showed a significant cell cycle arrest on selected cells after lectin treatment. Western blotting suggested that lectin up regulates the apoptotic protein expression in MCF-7 cells while it down regulates the level of Bcl-2 expression.

Abstract
Epidermal growth factor receptor antibody (EGFRAb) conjugated silica nanorattles (SNs) were synthesized and used to develop receptor mediated endocytosis for targeted drug delivery strategies for cancer therapy. The present study determined that the rate of internalization of silica nanorattles was found to be high in lung cancer cells when compared with the normal lung cells. EGFRAb can specifically bind to EGFR, a receptor that is highly expressed in lung cancer cells, but is expressed at low levels in other normal cells. Furthermore, in vitro studies clearly substantiated that the cPLA2α activity, arachidonic acid release and cell proliferation were considerably reduced by pyrrolidine-2 loaded EGFRAb-SN in H460 cells. The cytotoxicity, cell cycle arrest and apoptosis were significantly induced by the treatment of pyrrolidine-2 loaded EGFRAb-SN when compared with free pyrrolidine-2 and pyrrolidine-2 loaded SNs in human non-small cell lung cancer cells. An in vivo toxicity assessment showed that silica nanorattles and EGFRAb-SN-pyrrolidine-2 exhibited low systemic toxicity in healthy Balb/c mice. The EGFRAb-SN-pyrrolidine-2 showed a much better antitumor activity (38%) with enhanced tumor inhibition rate than the pyrrolidine-2 on the non-small cell lung carcinoma subcutaneous model. Thus, the present findings validated the low toxicity and high therapeutic potentials of EGFRAb-SN-pyrrolidine-2, which may provide a convincing evidence of the silica nanorattles as new potential carriers for targeted drug delivery systems.

Abstract
The aim of this study was to analyze if the 2-pyrrolidinone rich fraction of Brassica oleracea var. capitata exhibiting antioxidant and in vitro anticancer activities. 2-Pyrrolidinone is an active compound present in Brassica oleracea var. capitata. Our findings explored the potential use of 2-pyrrolidinone in cancer treatment. This compound was identified and isolated by gas chromatography-mass spectrometry and high-performance liquid chromatography from the leaf of Brassica oleracea var. capitata. The resultant rich active compound exhibited in vitro cytotoxicity in HeLa and PC-3 human cancer cell lines, and it also exhibited antioxidant activity in cell free assays. DAPI staining, an apoptotic analysis and cell cycle analysis were performed to evaluate the anticancer activity of 2-pyrrolidinone against the above cell lines. The IC50 value of 2-pyrrolidinone was determined to be of 2.5 µg/ml for HeLa, 3 µg/ml for PC-3 cells at 24 h and 1.5 µg/ml for HeLa and 2 µg/ml for PC-3 cells at 48 h, respectively. However, cell cycle analysis revealed that the anti-proliferative effects of the 2-pyrrolidinone were mediated through cell cycle arrest in the G0/G1 phase. These results from the current study suggest that the 2-pyrrolidinone have potential anticancer effects, which will lead to the development of new anticancer agents for arresting cancer cells growth in vitro.

Abstract
BACKGROUND AND AIMS The E2F3 transcription factor claims its role in controlling cell cycle progression. As reported earlier, nuclear E2F3 overexpression leads to development of bladder and prostate cancer in humans. Accordingly, the present investigation has been designed to assess to what extent E2F3 would be overexpressed in breast cancer. The aim of this study was to emphasize that the levels of E2F3 are increased in breast cancer and highlights the efficacy of siRNA targeted to E2F3. METHODS To investigate the expression level of E2F3 and the progression of breast tumors, quantitative real-time PCR analysis was carried out. Western blotting analysis was performed to measure its counterparts, namely, E2F3a and E2F3b. RESULTS In the novel axis of E2F3, a large set of 11 breast cancer cell lines were identified to have the property of overexpression. Furthermore, the small interfering RNA (siRNA) developed against E2F3 significantly blocked the expression of the E2F3 in the selected breast cancer cell lines. Thus, the present findings authenticate the efficiency of siRNA (E2F3) to fight against breast cancer; hence, the siRNA mediated E2F3 gene silencing knockdown the E2F3. CONCLUSIONS This in vitro study demonstrates that E2F3 is a newly identified diagnostic and potential therapeutic target in breast cancer. Outcomes of this study affirm that siRNA for E2F3 facilitates the silencing of E2F3 overexpression and fights against breast cancer. Therefore, it plays a vital role as an alternative for diagnosis and clinical outcome for the treatment of breast cancer.
