摘要:
A process for the surface functionalisation of a polymeric substrate, which process comprises: a) contacting the substrate with a diarylcarbene precursor, b) generating a carbene reactive intermediate from the diarylcarbene precursor so that it reacts with the substrate to functionalise the surface, and c) further functionalising the activated substrate obtained in step (b).

Novel alkyl ketone compounds having potent cytotoxic activity are described as antitumor agents and are particularly effective against leukemia and breast tumor cells. The compounds of the invention have formula (I), wherein R1-R4, X and p have the meanings given in the description.
摘要:
Inhibitors of oleamide hydrolase, responsible for the hydrolysis of an endogenous sleep-inducing lipid (1, cis-9-octadecenamide) were designed and synthesized. The most potent inhibitors possess an electrophilic carbonyl group capable of reversibly forming a (thio) hemiacetal or (thio) hemiketal to mimic the transition state of a serine or cysteine protease catalyzed reaction. In particular, the tight binding α-keto ethyl ester 8 (1.4 nM) and the trifluoromethyl ketone inhibitor 12 (1.2 nM) were found to have exceptional inhibitory activity. In addition to the inhibitory activity, some of the inhibitors displayed agonist activity which resulted in the induction of sleep in laboratory animals.
摘要:
The invention concerns a temperature-stable labelling reagent of formula (I), wherein: R1 represents H or an alkyl, aryl or substituted aryl group; R2 represents a detectable marker or at least two detectable markers linked together by at least a multimeric structure; L is a linking arm comprising a linear catemer concatenation of at least two covalent bonds; and n is an integer equal to 0 or 1; R?3 and R4¿ represent, independently of each other: H, NO¿2?, Cl, Br, F, I, R?2-(L)¿n-Y-X-, OR, SR, NR2, R, NHCOR, CONHR, COOR with R = alkyl or aryl, A is a linking arm comprising at least a double bond enabling the conjugation of the diazo function with the aromatic cycle; and u is a whole number between 0 and 2, preferably between 0 and 1; and -Y-X- represents -CONH-, -NHCO-, -CH2O-, -CH2S-. The invention also concerns a method for the synthesis of said markers and uses for labelling biological molecules, in particular nucleic acids, with a labelling reagent bearing the diazomethyl function. The invention is particularly applicable in the field of diagnosis.
