The aim was to determine the mycotoxin transfer rate into beer during a semi-industrial production process and the effect of fungicide treatment in the field on mycotoxins concentrations in beer. To ensure the usual practical agronomical conditions, sample A was treated with fungicide Prosaro 250, and sample B was infected with Fusarium culmorum spores, in order to obtain infected malt. Malt was produced using standard procedure and beer was produced in a semi-industrial unit. During fermentation measurement of sugars (maltotriose and maltose), glycerol and ethanol content was performed on a daily basis. Multiple toxins were determined in malt and beer. Deoxynivalenol (DON), its modified plant metabolite DON-3-glucoside (DON-glucoside), brevianamide F, tryptophol, linamarin, lotaustralin, culmorin (CUL), 15-hydroxy-CUL and 5-hydroyx-CUL were detected in all samples. Results indicate that F. culmorum infection did not influence the fermentation process or the alcohol concentration.

The control of ionic permselectivity in porous films is an interesting aspect in the context of lab-on-chip devices and mu-electronics. Especially, visible light triggered ionic permselectivity control is of relevance because control by light can be maintained externally without changing internal system parameters. In addition, light is a sustainable energy source if sunlight is used. Here, we present the first mesoporous films modified with two different photochromic homopolymers by surface-initiated ring opening metathesis polymerization (SI-ROMP). Spiropyran- and spirooxazine functionalized norbornene monomers and the corresponding ROMP homopolymers are synthesized in solution and in mesopores and compared concerning their optical properties such as photochromic conversion kinetics, photostability, and the ratio of converted molecules. Optical properties are investigated using UV/VIS spectroscopy and 1H-NMR spectroscopy. Especially, spirooxazine, whose surface functionalization has not been studied in detail, shows fast switching properties and higher ratios of photochromically interconverted molecules. After grafting spiropyran- and spirooxazine norbornene homopolymers into mesopores, a slightly faster photochromic interconversion of polymers located inside the mesopores is observed compared to the solution polymers.

A highly regioselective method has been developed for the allylation of indoles with an iridium catalyst. This regioselective procedure uses allylic alcohols directly as allylating agents in the presence of a catalytic amount of sulfuric acid. A wide range of indoles reacted smoothly with asymmetrical allylic alcohols to give the corresponding branched products in branched-to-linear ratios of up to 99:1 and yields as high as 92%. A series of inorganic and organic acids were tested in this approach, and it was shown that acids with pK a values in acetonitrile of less than 15 are required in this iridium-catalyzed system.

The anti-apoptotic protein survivin is highly expressed in cancer cells but has a very low expression in fully differentiated adult cells. Overexpression of survivin is positively correlated with cancer cell resistance to chemotherapy and radiotherapy, cancer cell metastasis, and poor patient prognosis. Therefore, selective targeting survivin represents an attractive strategy for the development of anticancer therapeutics. Herein, we reported the extensive structural modification of our recently discovered selective survivin inhibitor UC-112 and the synthesis of thirty-three new analogs. The structure-activity relationship (SAR) study indicated that replacement of the benzyloxy moeity in UC-112 with an indole moiety was preferred to other moieties. Among these UC-112 analogs, 10f, 10h, 10k, 10n showed the most potent antiproliferative activities. Interestingly, they were more potent against the P-glycoprotein overexpressing cancer cell lines compared with the parental cancer cell lines. Mechanistic studies confirmed that new analogs maintained their unique selectivity against survivin among the IAP family members. In vivo study using 10f in a human A375 melanoma xenograft model revealed that it effectively inhibited melanoma tumor growth without observable acute toxicity. Collectively, this study strongly supports the further preclinical development of selective survivin inhibitors based on the UC-112 scaffold.

In our search for potential new anticancer drugs, we designed and synthesized a series of tricyclic compounds containing the antimitotic 2-phenylazaflavone chromophore fused to a pyrrole ring in a pyrroloquinoline structure. Compounds 8, 18, 19, 22, 23, 25 and 26, when tested against a panel of fourteen human tumor cell lines, showed poor in vitro cytotoxic activity, whereas 20, 21 and 24 showed significant activity (IC50 0.7 to 50 muM). Steroid hormone-sensitive ovary, liver, breast and adrenal gland adenocarcinoma cell lines displayed the highest sensitivity (IC50 0.7 to 8 muM). Compound 24 blocked cells in the G2/M phase of the cell cycle and induced a significant increase in apoptotis. Compounds 20, 21 and 24 proved to alter microtubule assembly and stability, displaying a cytoplasmic microtubule network similar to that caused by Vincristine. In vivo, administration of compound 24 to Balb/c mice inhibited the growth of a syngenic hepatocellular carcinoma.

We discovered a novel series of 3,4-dihydro-2H-benzo[1,4]oxazin-8- yloxyacetic acid derivatives as potent dual-acting agents to block the TXA 2 receptor and to activate the PGI2 receptor. We report the synthesis, structure-activity relationship, and in vitro, ex vivo, and in vivo pharmacology of this series of compounds. 4-[2-(1,1-Diphenylethylsulfanyl) ethyl]-3,4-dihydro-2H-benzo[1,4]oxazin-8-yloxyacetic acid N-methyl-d-glucamine salt (7) is a promising candidate for a novel treatment in the anti-thrombotic and the cardiovascular fields avoiding hypotensive side effects.

Several C2-methylquinazoline-based antifolates (14-26) have been prepared in which the C9,N10 bridge has been replaced by the reversed N9,C10 unit.This series was extensively studied by incorporating further substituents at N9 and C10 as well as by modifications to the p-aminobenzoate ring.The C-2-methylquinazoline analogues 29, 30, and 31 containing the methyleneoxa, methylenethia, and thia bridge units were also synthesized.In general these isosteric replacements of the bridge unit in the parent C2-methyl-N10-propargylquinazoline antifolate 2 were much less potent as inhibitors of isolated thymidylate synthase (TS) but several were at least as potent as inhibitors of L1210 cell growth in culture.The fusion of the p-aminobenzoate ring into the bicyclic systems 75 and 76 also reduced activity against TS but again gave highly cytotoxic compounds.The cytotoxicities were largely prevented by thymidine, confirming that TS in the major locus.
