- Synthesis and evaluation of phosphorus containing, specific CDK9/CycT1 inhibitors
-
Although there is a significant effort in the design of a selective CDK9/CycT1 inhibitor, no compound has been proven to be a specific inhibitor of this kinase so far. The aim of this research was to develop novel and selective phosphorus containing CDK9/CycT1 inhibitors. Molecules bearing phosphonamidate, phosphonate, and phosphinate moieties were synthesized. Prepared compounds were evaluated in an enzymatic CDK9/CycT1 assay. The most potent molecules were tested in cell-based toxicity and HIV proliferation assays. Selectivity of shortlisted compounds against CDKs and other kinases was tested. The best compound was shown to be a highly specific, ATP-competitive inhibitor of CDK9/CycT1 with antiviral activity.

- An improved procedure for the synthesis of aryl phosphonates by palladium-catalysed cross-coupling of aryl halides and diethyl phosphite in polyethylene glycol
-
A general and greener protocol for the synthesis of aryl phosphonates by the cross-coupling of aryl halides and diethyl phosphite using tetrakis(triphenylphosphine)palladiume/triethylamine/polyethylene glycol 600 [Pd(PPh3)4/ Et3N/PEG 600] as an efficient catalytic system has been developed. This procedure also avoids hazardous solvents and is therefore an eco-friendly alternative to the existing methods.

- Design and synthesis of small molecule glycerol 3-phosphate acyltransferase inhibitors
-
The incidence of obesity and other diseases associated with an increased triacylglycerol mass is growing rapidly, particularly in the United States. Glycerol 3-phosphate acyltransferase (GPAT) catalyzes the ratelimiting step of glycerolipid biosynthesis, the acylation of glycerol 3-phosphate with saturated long-chain acyl-CoAs. In an effort to produce small molecule inhibitors of this enzyme, a series of benzoic and phosphonic acids was designed and synthesized. In vitro testing of this series has led to the identification of several compounds, in particular 2-(nonylsulfonamido)benzoic acid (15g), possessing moderate GPAT inhibitory activity in an intact mitochondrial assay.

- Aromatic nucleophilic polysubstitution by sequential SRN1 reactions

Substitution of aromatics (benzene, naphthalene and pyridine) by two or three distinct nucleophiles derived from phosphonates and/or thiolates can be performed by sequential photosimulated SRN1 reactions whose radical chain mechanism is compatible with the successively introduced substituents. aromatic polysubstitution / SRN1 mechanism / disubstituted aromatic / trisubstituted aromatic / distinct substituent

Our aim was to study the aromatic nucleophilic substitution between the sodium anion of diethylphosphite and several halogenated substrates like: iodo-anilines, iodo-nitrobenzenes, bromo- and iodopyridines, bromoquinoline.Two coupling processes have been evaluted.The first one is the photostimulated nucleophilic substitution (SRN1), the second the promoted arylation by transition metals.We obtain good results with the first method which is efficient and simple; by contrast the second one has given only few positive results.We describe five aromatic aminophosphonic acids.
