Estimating the value of the metal-ligand bond dissociation enthalpy (M-L) for adducts using empirical equations supported by TG data [PDF]

open access: yesQuímica Nova, 1999
In this work is presented and tested (for 106 adducts, mainly of the zinc group halides) two empirical equations supported in TG data to estimate the value of the metal-ligand bond dissociation enthalpy for adducts: (M-O) = t i / g if t i < 420 K and ...

Formation and metabolism of 6-(1-acetol)-8-(1-acetol)-rutin in foods and in vivo, and their cytotoxicity

open access: yesFrontiers in Nutrition, 2022
Methylglyoxal (MGO) is a highly reactive precursor which forms advanced glycation end-products (AGEs) in vivo, which lead to metabolic syndrome and chronic diseases. It is also a precursor of various carcinogens, including acrylamide and methylimidazole,

The Evolution of Circulating Biomarkers for Use in Acetaminophen/Paracetamol-Induced Liver Injury in Humans: A Scoping Review

open access: yesLivers, 2023
Acetaminophen (APAP) is a widely used drug, but overdose can cause severe acute liver injury. The first reports of APAP hepatotoxicity in humans were published in 1966, shortly after the development of alanine aminotransferase (ALT) and aspartate ...

Effect of bioactive aldehydes on gelatin properties [PDF]

open access: yesThe Ukrainian Biochemical Journal, 2015
Bioactive aldehydes are among main factors of proteins postsynthetic modifications, which are the cause and consequence of many diseases. Comparative study of some aldehydes modifying action on gelatin was carried out in vitro.

Thermal Study on Adducts of Urea with n-Alkanes and n-l-Alkanols [PDF]

open access: yes, 1971
Crystalline adducts of urea with n-alkanes (C(8)~C(20)) and n-l-alkanols (C(12)~C(18)) were prepared. From thermal analysis and X-ray diffraction study on the adducts, we found that the composition of adducts and the heat of decomposition can be obtained

Effects of Quercetin on Mushroom Tyrosinase and B16-F10 Melanoma Cells

open access: yesMolecules, 2007
In searching for tyrosinase inhibitors from plants using L-3,4-dihydroxyphenylalanine (L-DOPA) as a substrate, quercetin was found to be partially oxidized to the corresponding o-quinone under catalysis by mushroom tyrosinase (EC 1.14.18.1 ...

Mitosene-DNA adducts. Characterization of two major DNA monoadducts formed by 1,10-bis(acetoxy)-7-methoxymitosene upon reductive activation [PDF]

open access: yes, 1997
Reductive activation of racemic 1,10-bis(acetoxy)-7-methoxymitosene WV15 in the presence of DNA, followed by enzymatic digestion and HPLC analysis, revealed the formation of various DNA adducts.
