The invention provides a method for inactivation or reduction of pathogens, microorganisms or parasites in a sample, media, composition, utility, device, surface or organism by treatment with an alkylating compound of Structure I, followed by elimination or reduction of the residual compound with Structure I by treatment with a neutralizing agent, which eliminates or reduces the toxicity or other undesirable properties of the alkylating compound with Structure I. The neutralizing agent may be present in a treatment solution or be part of a solid-phase agent, and preferably acts by eliminating the alkylating properties of the compound of Structure I.

To provide a carrier linker that is capable of improving the water solubility of a physiologically active substance and more quickly releasing the physiologically active substance under specific conditions without utilizing light or enzymatic cleavage.
[Solution]A novel sugar chain-attached linker comprising a sugar chain that is attached as a carrier.
the aim of increasing the solubility and stability of the peptides in plasma. The amino or carboxyl group of the peptide was connected to a glycosylated Ascendis or ester/thioester-type linker, respectively. Use of the linkers enabled extended release of the peptides depending on the pH and temperature of the buffer according to a first order reaction, and their cleavage rate was also affected by the

peptide-(alpha)thiophenylester is a key reactant in nativechemicalligation. Preformation of the peptide-(alpha)thiophenylester could be useful for enhancing the ligation reaction. We report the direct on-resin preparation of preformed peptide-(alpha)thiophenylesters using a simple and efficient method. The peptide-(alpha)thiophenylester reacted extremely rapidly with a Cys-peptide when compared to the pe

The present invention relates to compounds for and a method of detecting beta-lactamase activity in a sample. The sample is contacted with a nanoparticulate tag. The nanoparticulate tag comprises a metal or a combination of metals, or it comprises a nanotube of a metal, boron nitride and/or carbon. The respective metal is capable of forming one of a covalent bond, a coordinative bond and a non-covalent interaction with a thio or a seleno group. The sample is contacted with a compound of one of general formulas (I)-(III) and (VII)-(IX). At least one beta-lactam moiety of the compound is cleaved by the beta-lactamase activity in the sample. As a result a cleavage moiety Z-A-Z, Z-A-Z-R

is released that is immobilised on the surface of the nanoparticulate tag by a covalent bond via a Z atom. The presence of beta-lactamase activity is determined based on the presence of the cleavage moiety immobilized onto the surface of the nanoparticulate tag.
