Aspirin‐Derived Salicyl‐CoA Drives Histone Lysine Salicylation Regulated by CBP and SIRT2

Advanced Science, EarlyView.
Aspirin‐derived salicyl‐CoA serves as a previously unrecognized acyl donor for protein lysine salicylation. This study identifies histone lysine salicylation as a reversible epigenetic modification regulated by CBP and SIRT2, expanding the biochemical actions of aspirin beyond its canonical acetylation‐dependent mechanisms and providing a new framework

Effect of Acylation of Flavones with Hydroxycinnamic Acids on their Spectral Characteristics

Natural Product Communications, 2007
The absorption spectra of twenty-one flavones including glycosides of apigenin, luteolin, chrysoeriol and tricin, nonacylated or acylated with coumaric, ferulic or sinapic acids, were examined to document the influence of acylation on their spectral ...

Unexpected reversal of the regioselectivity in Thermomyces lanuginosus lipase-catalyzed acylation of floxuridine

, 2009
Unexpected inversion of the 3':5'-regioselectivity was observed in the enzymatic methacryloylation, crotonylation and cinnamoylation of floxuridine (1.5:1, 2.3:1 and 4.4:1, respectively), where Thermomyces lanuginosus lipase preferentially catalyzed the ...

Oleate activates PLD2 lipase and GEF activity by modulating membrane microdomain dynamics via S-acylation

Journal of Lipid Research
Phospholipase D2 (PLD2) plays critical roles in cellular signaling, membrane dynamics, and cancer progression. Oleate (OA) has been shown to activate PLD2 and promote triple-negative breast cancer (TNBC) cell migration, but the underlying molecular ...

O-acylation of chitosan nanofibers by short-chain and long-chain fatty acids

, 2017
Chitosan nanofibers (CSNFs) have potential applications in biomaterials, oil recovery and food packaging, but their instability in moist environment has limited their full utilization. Here we report that CSNFs can be O-acylated in a post-electrospinning

Synthesis of 5-acylindoles via regioselective acylation of 3-trifluoroacetylindole

, 2003
5-Acylindoles were synthesized by regioselective acylation of 3-trifluoroacetylindole with acyl chloride under the catalysis of Lewis acids, followed by hydrolysis of trifluoroacetyl and decarboxylation.
