In a search of new compounds active against cancer, synthesis of a series of C-5 curcumin analogues was carried out. The new compounds demonstrated good cytotoxicity against chronic myeloid leukemia (KBM5) and colon cancer (HCT116) cell lines. Further, these compounds were found to have better potential to inhibit TNF-α-induced NF-κB activation in comparison to curcumin, which show their potential to act as anti-inflammatory agents. Some compounds were found to show higher cytotoxicity against cancer cell lines in comparison to curcumin used as standard.

Background: Nowadays the use of plant-derived products has been extensively examined in the treatment of many types of gastrointestinal cancers such as hepatocarcinoma and colon cancer. Urtica dioica is a traditional herb that has many pharmacological effects and wildly used as a therapeutic agent in cancer. Herein, we have evaluated the effects of the different concentrations of Methanolic Extract of Urtica dioica (MEUD) on viability, death pattern, and expression of the apoptosis-related gene in normal Human Dermal Fibroblast (HDF), hepatocarcinoma cell lines (HepG2) and colon-cancer cell line (HCT116). Methods: A high-performance liquid chromatography method was developed to simultaneously separate 3 phenolic acids in MEUD. HepG2 and HCT116 cell lines as well as HDF normal cell line were cultured in suitable media. After 24 and 48h, in the cultured cell with different concentrations of MEUD, cells viability was assessed by MTT assay, and apoptosis was also evaluated at the cellular level by Annexin V/PI flow cytometry analyzing and AO/EB staining. BCL2 and BAX gene expressions were assessed by TaqMan real-time PCR assay. Results: MEUD showed antiproliferative effects on HepG2 and HTC116 cells after 48h with an IC50 value of about 410 and 420μg/ml, respectively (P < 0.001). Apoptotic cells were observed in HepG2 and HTC116 cells but not in HDF. Furthermore, the increased level of BAX/BCL-2 ratio was observed in HepG2 and HTC116 cells under the treatment of different concentrations of MEUD. Conclusions: The MEUD may influence hepatocarcinoma and colon-cancer cell lines at specific doses and change their proliferation rate by changing the expression of BAX and BCL2.

Abstract 1H-Indole-2,3-dione (isatin) is an endogenous compound identified in many organisms, possesses a wide range of biological activities. Biological properties of isatin include a range of actions in brain and offer protection against certain types of infections. This molecule has a versatile moiety that displays diverse biological activities, including anticancer activity. The discovery of numerous biologically active 3-substituted 2-indolinones led in the past decade to extensive synthesis of related compounds and as a result, anticancer agents were developed. In particular, among the 5-substituted analogs tested in the growth inhibitions against several human cancer cell lines, 5-halide, methoxy and trifluoromethoxy groups containing 3-substituted 2-indolinones show high antiproliferative effects. For this purpose, we first synthesized twelve 5-fluoro-1H-indole-2,3-dione-3-thiosemicarbazones that antituberculosis activities were shown previously by our teamwork and we researched anticancer drug potential in this study. The cytotoxic effects of twelve thiosemicarbazone derivatives were investigated by MTT assay in chronic myeloid leukemia cell lines (K562, HL60), B-lymphoma cell lines (P3HR1) and in vincristine resistant forms. The IC50 values (IC50 is a concentration that kills 50% of cells) were calculated from dose-response curve according to cytotoxicity index. The effectiveness of thiosemicarbazone derivatives were evaluated by comparing IC50 values in leukemic cell lines. All of the compounds were found cytotoxic in B-lymphoma cell lines (P3HR1, P3HR1Vin) in range 0.95–2.41 μM. However, the allyl derivative of thiosemicarbazones has cytotoxic activity in all the cancer cell lines (K562, K562Vin, HL-60, P3HR1, P3HR1Vin) that were tested. As a result, 5-fluoro-1H-indole-2,3-dione-3-thiosemicarbazones derivates might have chemotherapeutic drug potential in B-lymphoma patients. The allyl derivative of thiosemicarbazones has benefit both B-lymphoma and chronic myeloid leukemia patients in a large spectrum.

Abstract Abstract 2741 Chronic myeloid leukemia (CML) is the best and most successful disease model for tyrosine kinase inhibitor (TKI). The mechanism of BCR-ABL leading transformation and signaling transduction networks have been intensively characterized over decades. However, resistance to TKIs remains a challenge in management of patients with CML. A better understanding BCR-ABL signaling network will lead to a better therapy. Here we report the discovery of a novel downstream target of BCR-ABL signalling, PRL-3 (PTP4A3), an oncogenic tyrosine phosphatase. Analysis of CML cancer cell lines and CML patient samples reveals the upregulation of PRL-3. A search of Gene Expression Atlas (http://www.ebi.ac.uk/gxa/gene/ENSG00000184489) identified the expression level of PRL-3 was highest in CML among 950 human cancer cell lines crossing 32 different types of cancers (Dataset code: E-MTAB-37), suggesting a potential role of PRL-3 in CML pathogenesis. Inhibition of BCR-ABL signalling either by Imatinib or by RNAi silencing BRC-ABL in CML cell line K562, KCL-22 and primary patient samples reduces PRL-3, in parallel with suppression of signal transducer and activator of transcription (STAT) pathway activities and increased cleavage of PARP, a hallmark of apoptosis. In contrast, the amount of PRL-3 protein remains constant or even increased in response to Imatinib treatment in drug resistant cells expressing BaF3-P210 T315I. Finally, analysis with specific shRNA demonstrated K562-shPRL-3 (shP) cells proliferated as much as 2-time lesser than K562-shControl (shC) at day 8 (p < 0.001). Colony-forming efficiency is an indicator of self-renewal capacity of leukemic cell. K562-shP cells also showed significantly impaired colony generating capacity by 3-fold compared to K562-shC (p < 0.001). These results indicate a critical role for PRL-3 in CML cell expansion and self-renewal. In summary, the present study demonstrates that PRL-3 is remarkably upregulated in human CML cell lines, BCR-ABL transformed cell lines and primary CML patient samples. Our results highlight that PRL-3 is a novel downstream target of BCR-ABL pathway, which is crucial for BRC-ABL-mediated cell survival and self-renewal. These data support a functionally important role of PRL-3 in CML biology downstream of BCR-ABL and maybe a viable therapeutic target in BCR-ABL positive cells even in those with Imatinib resistant mutations. Disclosures: Off Label Use: Imatinib will be used as a tool to dissect BCR-ABL signaling.

The implementation of chemo- and bioinformatics tools is a crucial step in the design of structure-based drugs, enabling the identification of more specific and effective molecules against cancer without side effects. In this study, three new compounds were designed and synthesized with suitable absorption, distribution, metabolism, excretion and toxicity (ADME-tox) properties and high affinity for the G protein-coupled estrogen receptor (GPER) binding site by in silico methods, which correlated with the growth inhibitory activity tested in a cluster of cancer cell lines. Docking and molecular dynamics (MD) simulations accompanied by a molecular mechanics/generalized Born surface area (MMGBSA) approach yielded the binding modes and energetic features of the proposed compounds on GPER. These in silico studies showed that the compounds reached the GPER binding site, establishing interactions with a phenylalanine cluster (F206, F208 and F278) required for GPER molecular recognition of its agonist and antagonist ligands. Finally, a 3-(4,5-dimethylthiazol-2-yl)2,5-diphenyltetrazolium bromide (MTT) assay showed growth inhibitory activity of compounds 4, 5 and 7 in three different cancer cell lines—MIA Paca-2, RCC4-VA and Hep G2—at micromolar concentrations. These new molecules with specific chemical modifications of the GPER pharmacophore open up the possibility of generating new compounds capable of reaching the GPER binding site with potential growth inhibitory activities against nonconventional GPER cell models.

Abstract Background Recent evidence proves that intravenous human immunoglobulin G (IgG) can impair cancer cell viability. However, no study evaluated whether IgG application benefits cancer patients receiving chemotherapeutics. Methods Influence of pharmaceutical-grade human IgG on the viability of a series of patient-derived colon cancer cell lines with and without chemotherapeutic intervention was determined. Cell death was analysed flow cytometrically. In addition, the influence of oxaliplatin and IgG on the ERK1/2-signalling pathway was evaluated by western blots. Results We evaluated the effects of pharmaceutical IgG, such as PRIVIGEN® IgG and Tonglu® IgG, in combination with chemotherapeutics. We did not observe any significant effects of IgG on tumour cell viability directly; however, human IgG significantly impaired the anti-tumoral effects of oxaliplatin. Primary cancer cell lines express IgG receptors and accumulate human IgG intracellularly. Moreover, while oxaliplatin induced the activation of ERK1/2, the pharmaceutical IgG inhibited ERK1/2 activity. Conclusions The present study demonstrates that pharmaceutical IgG, such as PRIVIGEN® IgG and Tonglu® IgG, can impair the anti-carcinoma activity of oxaliplatin. These data strongly suggest that therapeutic IgG as co-medication might have harmful side effects in cancer patients. The clinical significance of these preclinical observations absolutely advises further preclinical, as well as epidemiological and clinical research.

A panel of monoclonal antibodies (n=72 including controls) directed against lung cancer antigens was screened immunohistochemically against a panel of seven human lung cancer cell lines (including small cell carcinoma, squamous cell carcinoma, adenocarcinoma and mesothelioma), six human breast cancer cell lines and one human colon cancer cell line, The majority of the antibodies (n=42) reacted also with antigens present on breast and colon cancer cell lines, This cross reactivity especially between lung and breast cancer cell lines is not altogether unexpected since antigens common to breast and lung tissue including their neoplasms such as MUC1 antigen have been described, Our results indicate that epitopes shared by lung and breast cancers are probably more common than previously thought. The relevance for prognosis and therapy of these shared antigens, especially as disease markers in breast cancer, has to be investigated.

The purpose of this study was to determine the quantity and nature of the mucins synthesized and secreted by four different pancreatic cancer cell lines. Well- to moderately-differentiated SW1990 and CAPAN-2 human pancreatic cancer cells were found to produce more high-Mr glycoprotein (HMG) than less-differentiated MIA PaCa-2 and PANC-1 cells. Most of the labelled HMG was secreted within 24 h. The results of chemical and enzymic degradation, ion-exchange chromatography and density-gradient centrifugation indicated that the HMG in SW1990 and CAPAN-2 cells has the properties expected for mucins, whereas much of the HMG in MIA PaCa-2 and PANC-1 cells may not be mucin, but proteoglycan. These results are consistent with immunoblots and Northern blots showing the presence of apomucin and apomucin mRNA in SW1990 and CAPAN-2 cells, but not in MIA PaCa-2 and PANC-1 cells. The Western blots and Northern blots also show that SW1990 and CAPAN-2 cells, like breast cancer cells, have the mammary-type apomucin and mRNA coded by the MUC1 gene, but lack the intestinal type apomucin and mRNA coded by the MUC2 gene. In contrast, the colon cancer cell lines tested in culture express apomucin and mRNA coded by MUC2 but not by MUC1.
