The effects of two levels (1.4 vs 2.8%) of fresh garlic on lipid oxidation and microbial growth in pork patties were evaluated. Hunter color (L, a, b), pH, thiobarbituric acid reactive substances (TBARS), oxidative volatile compounds, total bacteria and Enterobacteriaceae in the pork patties with or without fresh garlic were measured during storage at 4℃. Addition of fresh garlic decreased redn...

The present studies compared the effects of various oil-soluble compounds containing allyl and disulfide groups on the proliferation of cultured human colon tumor cells (HCT-15). Diallyl disulfide (DADS) was more effective in inhibiting the growth of HCT-15 cells than isomolar concentrations of S-allyl cysteine, dipropyl disulfide (DPDS), allyl chloride, allyl glycidyl ether and allyl alcohol. ...

Monodentate phosphine-ligated nickel compounds, e.g., [Ni(PPh3)4] are relevant as active catalysts across a broad range of reactions. This report expands upon the coordination chemistry this family, offering reactivity allyl- and vinyl-substituted diphenylphosphine (PPh2R) with [Ni(COD)2] (COD = 1,5-cyclooctadiene). These reactions provide three-coordinate dinickelacycles that intermolecularly ...

The bark of Litsea costalis affords two new compounds named 4,4'-diallyl-5,5'-dimethoxy-[1,1'-biphennyl]-2,2'-diol, biseugenol A (1) and 2,2'-oxybis (4-allyl-1-methoxybenzene), biseugenol B (2) along with two known compounds (3-4), namely 5-methoxy-2-Hydroxy Benzaldehyde (3), and (E)-4-styrylphenol (4). The structures of 1 and 2 were determined using 1D and 2D NMR data. Also, the IR and NMR dat...

Homoallylic ketones combine arguably two of the most synthetically useful functional groups in organic chemistry and are, therefore, very valuable synthetic intermediates. General methods for the synthesis of these intermediates include the allylation of carbonyl compounds via p-allyl palladium(II) complexes, the 1,4-addition of vinylmetal nucleophiles onto a,bunsaturated compounds, and the Cla...

Utilizing the sulfur-containing gases of garlic as probes, we investigated the gut versus mouth origin of odoriferous breath gases. Five individuals ingested 6 g of garlic, and sulfur gases in mouth, alveolar air, and urine samples were measured. The mouth normally contained low concentrations of hydrogen sulfide, methanethiol, and dimethyl sulfide. Immediately after garlic ingestion, transient...

Functionalized acyclic and cyclic guanidines have a wide range of biological activity. In particular, they possess antitumor, antibacterial activities, are immunosuppressants, anesthetics, analgesics analogues natural alkaloids. The search methods for the synthesis new guanidine derivatives is an urgent problem.

N-Allyl derivatives of uracil (U), thymine (T) and 6-methyluracil (6-MU) were prepared, and their pharmacological activities (hypnotic activity and anticonvulsant activity against pentylenetetrazol (PTZ)-induced seizures) and interactions with three sedative-hypnotics [pentobarbital (PB), barbital (B) and diazepam (DZ)] were investigated in mice. AO,N3-Diallyluracil (DAU) alone exhibited hypnot...
