Two newly synthesized water-soluble phthalocyanine Zn(II) complexes with different charges, cationic methylpyridyloxy-substituted Zn(II)- phthalocyanine (ZnPcMe) and anionic sulfophenoxy-substituted Zn(II)-phthalocyanine (ZnPcS), were used for photoinactivation of two DNA-containing enveloped viruses (herpes simplex virus type 1 and vaccinia virus), two RNA-containing enveloped viruses (bovine viral diarrhea virus and Newcastle disease virus) and two nude viruses (the enterovirus Coxsackie B1, a RNA-containing virus, and human adenovirus 5, a DNA virus). These two differently charged phthalocyanine complexes showed an identical marked virucidal effect against herpes simplex virus type 1, which was one and the same at an irradiation lasting 5 or 20 min (Δlog=3.0 and 4.0, respectively). Towards vaccinia virus this effect was lower, Δlog=1.8 under the effect of ZnPcMe and 2.0 for ZnPcS. Bovine viral diarrhea virus manifested a moderate sensitivity to ZnPcMe (Δlog=1.8) and a pronounced one to ZnPcS at 5- and 20-min irradiation (Δlog=5.8 and 5.3, respectively).

However, the details of AR formation at the molecular level have not been determined in lotus. Therefore, three stages were chosen to identify the change of proteins abundant during rhizome formation, using isobaric tags for relative and absolute quantization coupled with liquid chromatography–tandem mass spectrometry to gain insight into the molecular mechanisms involved in AR formation. We totally obtained 323,375 spectra during AR formation. After filtering to eliminate low-scoring spectra, 66,943 spectra, including 53,106 unique spectra, were identified. These unique spectra matched 28,905 peptides, including 24,992 unique peptides, which were assembled into 6686 proteins. In the C0/C1 and C1/C2 stages, 66 and 32 proteins showed enhanced abundance, and 173 and 73 proteins showed decreased abundance, respectively. Seventeen important AR formation-related proteins from the three stages were identified, and the expressions of nine genes from the above-identified proteins were assessed by qRT-PCR. This article provides a comprehensive understanding of the changes in metabolism during AR formation, and is helpful to accelerate the progress of breeding in fulture in lotus root.","PeriodicalId":23894,"journal":{"name":"Zeitschrift für Naturforschung C","volume":"30 10","pages":"181 - 196"},"PeriodicalIF":0.0,"publicationDate":"2016-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91512268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Naproxen [(S) 6-methoxy-α-methyl-2-naphthalene acetic acid] and its sodium salt are members of the α-arylpropionic acid group of nonsteroidal anti-inflammatory drugs. Due to excessive usage of naproxen, this drug has been determined even in drinking water. In this study, four fungal strains Phanerochaete chrysosporium, Funalia trogii, Aspergillus niger, and Yarrowia lipolytica were investigated in terms of naproxen removal abilities. According to LC/MS data, A. niger was found the most efficient strain with 98% removal rate. Two main by-products of fungal transformation, O-desmethylnaproxen and 7-hydroxynaproxen, were identified by using LC/MS, 1HNMR, and 13CNMR. Our results showed that O-demethylation and hydroxylation of naproxen is catalyzed by cytochrome P450 enzyme system.","PeriodicalId":23894,"journal":{"name":"Zeitschrift für Naturforschung C","volume":"186 1","pages":"173 - 179"},"PeriodicalIF":0.0,"publicationDate":"2016-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74881423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
