Influence of Two Garlic-Derived Compounds, Propyl Propane Thiosulfonate (PTS) and Propyl Propane Thiosulfinate (PTSO), on Growth and Mycotoxin Production by Fusarium Species In Vitro and in Stored Cereals.

Only registered users can translate articles

Two garlic-derived compounds, Propyl Propane Thiosulfonate (PTS) and Propyl Propane Thiosulfinate (PTSO), were examined for their efficacy against mycotoxigenic Fusarium species (F. graminearum, F. langsethiae, F. verticillioides). The objectives were to assess the

Genotoxicity assessment of propyl thiosulfinate oxide, an organosulfur compound from Allium extract, intended to food active packaging.

Only registered users can translate articles

Essential oils from onion (Allium cepa L.), garlic (Allium sativum L.), and their main components, such as propyl thiosulfinate oxide (PTSO) are being intended for active packaging with the purpose of maintaining and extending food product quality and shelf life. The present work aims to assess for

Topical Applications of Thiosulfinate-Enriched Allium sativum Extract Accelerates Acute Cutaneous Wound Healing in Murine Model.

To determine whether topical applications of thiosulfinate-enriched Allium sativum extract (TASE) can accelerate acute cutaneous wound healing (WH) in a murine model.Keratinocyte viability and in vitro wound closure were assessed in keratinocyte cultures.

Applications of direct analysis in real time-mass spectrometry (DART-MS) in Allium chemistry. (Z)-butanethial S-oxide and 1-butenyl thiosulfinates and their S-(E)-1-butenylcysteine S-oxide precursor from Allium siculum.

Lachrymatory (Z)-butanethial S-oxide along with several 1-butenyl thiosulfinates was detected by DART mass spectrometry upon cutting Allium siculum , a popular ornamental Allium species used in some cultures as a spice. (Z)-Butanethial S-oxide isolated from the plant was shown to be identical to a

Isolation of S-n-butylcysteine sulfoxide and six n-butyl-containing thiosulfinates from Allium siculum.

Only registered users can translate articles

Isolation and identification of (S(S)R(C))-S-n-butylcysteine sulfoxide (1) from the bulbs of Allium siculum is reported. This compound was found in all parts of the plant (bulbs, stem, leaves, and flowers) along with known compounds (S(S)R(C))-S-methyl- and (R(S)R(C))-(E)-S-(1-propenyl)cysteine

The reaction of sulfenic acids with peroxyl radicals: insights into the radical-trapping antioxidant activity of plant-derived thiosulfinates.

Only registered users can translate articles

Sulfenic acids play a prominent role in biology as key participants in cellular signaling relating to redox homeostasis, in the formation of protein-disulfide linkages, and as the central players in the fascinating organosulfur chemistry of the Allium species (e.g., garlic). Despite their relevance,

The mechanism of radical-trapping antioxidant activity of plant-derived thiosulfinates.

Only registered users can translate articles

It has long been recognized that garlic and petiveria, two plants of the Allium genus--which also includes onions, leeks and shallots--possess great medicinal value. In recent times, the biological activities of extracts of these plants have been ascribed to the antioxidant properties of the

Jack bean urease inhibition by crude juices of Allium and Brassica plants. Determination of thiosulfinates.

Only registered users can translate articles

The aim of this study was the elucidation of the inhibitory influence of Allium (garlic, onion, leek) and Brassica (cabbage, Brussels sprouts) plants juices, on jack bean urease activity. Concentrations of thiosulfinates, the compounds responsible for the inhibition, were determined in studied

Garlic extract methylallyl thiosulfinate blocks insulin potentiation of platelet-derived growth factor-stimulated migration of vascular smooth muscle cells.

Only registered users can translate articles

Platelet-derived growth factor (PDGF) is a potent inducer of vascular smooth muscle cell (VSMC) migration, whereas insulin, in physiological concentrations, helps maintain the nonproliferative phenotype of these cells. However, hyperinsulinemia (10 nmol/L) significantly potentiates the PDGF (30

A spectrophotometric assay for allicin and alliinase (Alliin lyase) activity: reaction of 2-nitro-5-thiobenzoate with thiosulfinates.

Only registered users can translate articles

Allicin (diallylthiosulfinate) is the main biologically active component of freshly crushed garlic cloves. It is produced upon the interaction of the nonprotein amino acid alliin with the enzyme alliinase (alliin lyase, EC 4.4.1.4). A simple and rapid spectrophotometric procedure for determination

The medicinal thiosulfinates from garlic and Petiveria are not radical-trapping antioxidants in liposomes and cells, but lipophilic analogs are.

Only registered users can translate articles

The radical-trapping antioxidant (RTA) activities of allicin and petivericin, thiosulfinates widely believed responsible for the medicinal properties of garlic and Petiveria, were determined in phosphatidylcholine lipid bilayers. The results indicate that both compounds are surprisingly ineffective,

Antimicrobial activity of the thiosulfinates isolated from oil-macerated garlic extract.

Only registered users can translate articles

Three thiosulfinates were isolated from oil-macerated garlic extract, and their structures were identified as 2-propene-1-sulfinothioic acid S-(Z,E)-1-propenyl ester [AllS(O)SPn-(Z,E)], 2-propenesulfinothioic acid S-methyl ester [AllS(O)SMe], and methanesulfinothioic acid S-(Z,E)-1-propenyl ester

Cysteine reacts to form blue-green pigments with thiosulfinates obtained from garlic (Allium sativum L.).

Only registered users can translate articles

Cysteine was found to form pigments with garlic thiosulfinates in this investigation, in contrast to previous reports. Pigments were formed only when the molar concentration ratios of cysteine to total thiosulfinates were smaller than 2:1. Cysteine does not form pigments with thiosulfinates in the

Resistance of Garlic Cultivars to Bradysia odoriphaga and Its Correlation with Garlic Thiosulfinates.

Only registered users can translate articles

Garlic, a widely cultivated global vegetable crop, is threatened by the underground pest Bradysia odoriphaga in China. Previous reports indicated that garlic essential oil, of which the dominant components are sulfides or thiosulfinates, exhibits insecticidal activity against pests. However, it is

Identification and HPLC quantitation of the sulfides and dialk(en)yl thiosulfinates in commercial garlic products.
