(E)-3-Cyanophosphoenolpyruvate has been synthesized by reacting dimethyl chlorophosphate with the potassium enolate of ethyl cyanopyruvate. The resulting trialkyl ester was deesterified with bromotrimethylsilane followed by potassium hydroxide. Subsequent treatment with Dowex-50-H+ resin and cyclohexylamine afforded the tricyclohexylammonium salt; only the

The fundamental interactions of dimethyl methylphosphonate (DMMP) and dimethyl chlorophosphate (DMCP) on amorphous silica nanoparticles have been investigated with transmission infrared spectroscopy and temperature-programmed desorption (TPD). DMMP and DMCP both adsorb molecularly to silica through the formation of hydrogen bonds

The poor aqueous solubility of 2-arachidonyl glyceryl ether (noladin ether) 2 hinders both pharmacological studies and pharmaceutical development. The synthesized mono- and diphosphate esters of noladin ether (4 and 6) considerably increased the aqueous solubility of noladin ether (>40000-fold), showed

Quorum sensing (QS) inhibitor-based therapy is an attractive strategy to inhibit bacterial biofilm formation without excessive induction of antibiotic resistance. Thus, we designed Ca2+-binding poly(lactide- co-glycolide) (PLGA) microparticles that can maintain a sufficient concentration of QS inhibitors around hydroxyapatite (HA)
