Enhancement of anticancer potential of polyphenols by covalent modifications

Biochemical Pharmacology, 2016
As evidenced by a growing number of respective clinical trials, a promising and increasingly valued approach to cancer prevention is chemoprevention which is based on using synthetic, semisynthetic, or natural compounds with the aim of preventing, delaying, arresting, or reversing carcinogenesis.

Improvement by Covalent and Noncovalent Modification

1978
As mentioned in earlier Chapters, cyclodextrins exhibit many interesting features such as rate effects, stereospecificity, enantiomeric specificity, etc., in organic reactions. However, there is one serious hortcoming of cyclodextrins as catalysts.

Tyrosinase enhances the covalent modification of DNA by dopamine

Molecular Brain Research, 1996
Dopamine-induced DNA damage was studied in vitro in the presence of the enzyme tyrosinase. Dopamine auto-oxidizes to form dopamine quinone, a reactive molecule which spontaneously decomposes to form additional reactive species that can modify cellular macromolecules.

Posttranslational covalent modification of proteins.

Science (New York, N.Y.), 1978
A search for derivatized amino acids in proteins has shown that the extent of posttranslational modification of proteins is quite substantial. While only 20 primary amino acids are specified in the genetic code and are involved as monomer building blocks in the assembly of the polypeptide chain, about 140 amino acids and amino acid derivatives have ...

Covalent modification of nuclear proteins during aging

1975
An in vitro assay system has been established to study acetylation and phosphorylation of nuclear proteins from isolated nuclei. Phosphorylation of neclear proteins reached a peak within 5 min while maximum acetylation occurred about 10 min later. The rate of acetylation of liver nuclear proteins in 15 min incubation was significantly higher in "old ...

Nonenzymatic Covalent Posttranslational Modification of Proteins In Vivo

1985
Publisher Summary This chapter presents the in vivo analysis of non-enzymatic covalent post-translational modification of proteins. Enzyme-controlled post-translational modification of proteins, especially enzymes, has been demonstrated in many tissues and organisms. These post-translational modifications are of the utmost importance in the control
