Three new fluorous supports for peptide synthesis, i.e., the trialkoxybenzhydryl-type (6), the Wang-type (7) and the tert-butyl-type support (8), were prepared. A bioactive peptide TRH was easily synthesized by an Fmoc strategy using the benzhydryl-type fluorous support with fluorous chemistry.
high purity using only 1.2 to 2 equivalents of coupling reagents. The supportcan be isolated as a precipitate from the reaction medium by adding ether. The loading capacity of the supportcan be easily determined by spectroscopy and can also be tuned by varying the monomer ratio. This support is promising for accessing peptides as the methodology uses minimal reagents and by-products can be easily separated

The present invention provides novel tetrahydrocarbazole derivatives which have improved properties and which can be employed as inhibitors of GPCRs. This results in the possibility of using the novel compounds to treat pathological conditions whose severity depends on the pathobiochemical effect of GPCRs. The compounds of the invention act in particular via an antagonistic inhibition of the LHRH receptor. The invention further provides medicaments which comprise one or more of the novel compounds as active ingredient. The medicaments are suitable in particular to be employed in an oral dosage form for a mammal, in particular a human.

functionalized imidazolium ions containing a pyridine moiety and carboxylic acid functionality has been synthesized in solution. These compounds serve as N-heterocyclic carbene precursors and were attached to a dipeptide on solid support by means of standard peptide coupling techniques. Treatment with base generated the corresponding carbenes, which were directly complexed to palladium(II) and subsequently studied

A probe is provided comprising a label and a binding moiety, wherein the binding moiety is adapted to bind to gram-negative bacteria, and to substantially not bind to animal cells or gram-positive bacteria. A method of detecting the presence of bacteria in a target area is also provided, which allows the detection of bacteria generally, and the determination of whether that bacteria is gram negative or gram positive.
