Pharmaceutical and Safety Profile Evaluation of Novel Selenocompounds with Noteworthy Anticancer Activity. Pharmaceutics 2022; 14:pharmaceutics14020367.

Abstract
Prior studies have reported the potent and selective cytotoxic, pro-apoptotic, and chemopreventive activities of a cyclic selenoanhydride and of a series of selenoesters. Some of these selenium derivatives demonstrated multidrug resistance (MDR)-reversing activity in different resistant cancer cell lines. Thus, the aim of this study was to evaluate the pharmaceutical and safety profiles of these selected selenocompounds using alternative methods in silico and in vitro. One of the main tasks of this work was to determine both the physicochemical properties and metabolic stability of these selenoesters. The obtained results proved that these tested selenocompounds could become potential candidates for novel and safe anticancer drugs with good ADMET parameters. The most favorable selenocompounds turned out to be the phthalic selenoanhydride (EDA-A6), two ketone-containing selenoesters with a 4-chlorophenyl moiety (EDA-71 and EDA-73), and a symmetrical selenodiester with a pyridine ring and two selenium atoms (EDA-119).

Responses of an American eel brain endothelial-like cell line to selenium deprivation and to selenite, selenate, and selenomethionine additions in different exposure media.

Abstract
The effect of selenium deprivation and addition on the American eel brain endothelial cell line (eelB) was studied in three exposure media: complete growth medium (L15/FBS), serum-free medium (L15), and minimal medium (L15/ex). L15/ex contains only galactose and pyruvate and allowed the deprivation of selenium on cells to be studied. In L15/ex, without any obvious source of selenium, eelB cells survived for at least 7 d, formed capillary-like structures (CLS) on Matrigel, and migrated to heal wounds. Three selenium compounds were added to cultures: selenite, selenate, and selenomethionine (SeMet). Adding selenite or selenate to eelB cell cultures for 24 h caused dose-dependent declines in cell viability, regardless of the exposure media. Although varying with exposure media and viability end point, selenite was approximately 70-fold more cytotoxic than selenate. By contrast, 24 h exposures to either DL- or L-SeMet in the three media caused little or no cytotoxicity. However for 7 d exposures in L15/ex, DL- and L-SeMet were very cytotoxic, even at the lowest tested concentration of 31 μM. By contrast in L15 and L15/FBS, cytotoxicity was only observed with 500 and 1000 μM L-SeMet. In L15/FBS, eelB continued to migrate and form CLS in the presence of SeMet but at 500 μM, cell migration appeared stimulated. As judged from a colony-forming assay over 14 d in L15/FBS, 500 and 1000 μM DL- and L-SeMet inhibited cell proliferation. Overall, the responses of eel cells to selenium depended on the selenium form, concentration, and exposure media, with responses to SeMet being most dependent on exposure media.

Exp Cell Res 2011; 317:1746-62.

Abstract
Bone morphogenetic proteins (BMPs) have been implicated in tumorigenesis and metastatic progression in various types of cancer cells, but the role and cellular mechanism in the invasive phenotype of gastric cancer cells is not known. Herein, we determined the roles of phosphoinositide 3-kinase (PI3K)/AKT, extracellular signal-regulated protein kinase (ERK), nuclear factor (NF)-κB, and matrix metalloproteinase (MMP) expression in BMP-2-mediated metastatic function in gastric cancer. We found that stimulation of BMP-2 in gastric cancer cells enhanced the phosphorylation of AKT and ERK. Accompanying activation of AKT and ERK kinase, BMP-2 also enhanced phosphorylation/degradation of IκBα and the nuclear translocation/activation of NF-κB. Interestingly, blockade of PI3K/AKT and ERK signaling using LY294002 and PD98059, respectively, significantly inhibited BMP-2-induced motility and invasiveness in association with the activation of NF-κB. Furthermore, BMP-2-induced MMP-9 expression and enzymatic activity was also significantly blocked by treatment with PI3K/AKT, ERK, or NF-κB inhibitors. Immunohistochemistry staining of 178 gastric tumor biopsies indicated that expression of BMP-2 and MMP-9 had a significant positive correlation with lymph node metastasis and a poor prognosis. These results indicate that the BMP-2 signaling pathway enhances tumor metastasis in gastric cancer by sequential activation of the PI3K/AKT or MAPK pathway followed by the induction of NF-κB and MMP-9 activity, indicating that BMP-2 has the potential to be a therapeutic molecular target to decrease metastasis.

Abstract
DNA repair is crucial to the integrity of the human genome since mammalian cells are continuously exposed to different chemical and physical genotoxic agents. To counteract the lesions induced by these agents, organisms have developed a number of highly conserved repair mechanisms involving numerous protein complexes grouped in several different repair pathways. The importance of studying the individual capacity to repair DNA damage lies in the observation that deficient repair mechanisms of the genome have been linked to the presence of large number of diseases and cancer, and alterations in these mechanisms may also alter the susceptibility of individuals exposed to a particular mutagen. This review focused on the current knowledge of different assays developed to evaluate DNA repair capacity (DRC). These assays, which are grouped into five major categories, have been successfully applied in (1) in vitro studies, (2) epidemiological studies in patients with cancer or other different pathologies, and (3) environmentally or occupationally exposed populations. Nevertheless, some of the limitations include high interlaboratory variability and difficulty to implement the assays on a large scale. The selection of an adequate DRC assay needs to be made on the basis of the objective raised for its application and taking into account a number of determining factors, namely, (1) speed and cost, (2) type of DNA repair to be evaluated, and (3) sample availability.

Abstract
Murine (Hepa1c1c7) hepatoma cells are a suitable in vitro system for investigating the regulation of chemoprotective enzymes by selenazolidines, novel l-selenocysteine prodrugs developed as potential chemopreventive agents. They are less sensitive to the cytotoxic effects of both selenite and the less toxic selenazolidines than rat hepatoma (H4IIE) cells. All four selenazolidine 4-carboxylic acid (SCA) derivatives examined elevated thioredoxin reductase (Txnrd1), alpha-class glutathione transferases (Gsta), and UDP-glucuronosyltransferase (Ugt)1a6 mRNAs. NAD(P)H-quinone oxidoreductase (Nqo1) was induced by the three 2-alkyl derivatives (2-cyclohexylSCA, 2-butylSCA, and 2-methylSCA) but not SCA itself. Transcripts of mu- and pi-class glutathione transferases were induced only by 2-cyclohexylSCA and 2-butylSCA. Only Gsta and Txnrd1 transcripts were elevated by l-selenomethionine, l-selenocystine, or Se-methyl-l-selenocysteine. Txnrd1, Gsta, Nqo1, and Gstp responses to selenazolidines were all abolished by actinomycin D while Ugt1a6 responses were not. Induction responses to the selenazolidines were also eliminated (most) or reduced (Txnrd1 by 2-methylSCA) by cycloheximide, with the exception of Ugt1a6. The Ugt1a6 mRNA levels in the presence of SCAs and cycloheximide were similar to those with cycloheximide alone, and were almost double those of vehicle-treated cells. Thus, Hepa1c1c7 cells appear to provide a viable platform for the study of protective enzyme regulation by selenocompounds, and with the exception of Ugt1a6, the mRNA elevations from selenazolidines are transcriptionally dependent.

Abstract
Helicobacter pylori (HP) acquired in childhood is an important risk factor for gastric carcinoma. Once colonization is established, infection may be carried for life. The relationship between food intake and HP infection, the presence of metals and phytochemicals closely associated with oxidative stress within everyday diet are important topics to be considered. The possible anti-HP effects of phytochemicals, prooxidant effects exerted in the presence of metal species, intimate relations between some metals and HP, bivalent effects of some metal species in cancer, interactions between metal species and phytochemicals in HP infection are the topics, which require further research. Formulas or diets enriched with phytochemicals and metals against HP and, which are devoid of metals known to favour the growth of HP, may be suggested as the supplements to the classical treatment regimens. The importance of collective consideration of HP, metal species and phytochemicals should be emphasized.
