摘要:Penicillins and cephalosporins can be synthesized by the action of an acylase on a penicillin or cephalosporin nucleus amine as substrate and an ester (I) of the following formula as the acyl source: (I) (wherein RCO is an acyl group in penicillin or cephalosporin side chains; X is a hydrogen atom, lower alkyl group or hydroxy-lower alkyl group; Y is a hydrogen atom or a lower alkyl group; and n is a positive integer). The novel acyl source (I) is also disclosed.

摘要:The invention provides methods for the preparation of small molecule drugs that are chemically modified by covalent attachment of a water-soluble oligomer obtained from a water-soluble oligomer composition. Such drugs are produced through modification of a synthetic pathway to attach the oligomer to an intermediate compound followed by completion of the synthetic path.

摘要:The invention relates to a method for the preparation of a coating comprising at least one coating layer on a substrate, the method comprising the steps of a. providing monomers of the type R—(N) x -(L) m -(Câ•?C) n -(L′) o -(N′) y —R′, wherein R is a head moiety, R′ is a tail moiety, (C≡C) n is an oligoyne moiety, L and L′ are linker moieties, N and N′ independently are branched or unbranched optionally substituted C 1 -C 25 alkyl moieties optionally containing 1 to 5 heteroatoms, x, m, o, and y are independently 0 or 1, n is 4 to 12, and wherein the head moiety allows for an interaction with the surface of the substrate; b. bringing the monomers into contact with the substrate wherein the interaction of the head moieties of the monomers with the surface of the substrate induces at least a part of the monomers to align in a defined manner thereby forming a film on the surface and bringing the oligoyne moieties of the monomers into close contact with each other; c. inducing a reaction between oligoyne moieties by providing an external stimulus so as to at least partially cross-link the aligned monomers, thereby forming a coating layer on the substrate. The invention further relates to a coating obtainable according to the method of the invention, the use of a coating obtainable according to the method of the invention, a substrate comprising a coating obtainable according to the invention and the use of solid substrate. The invention further relates to a method for the synthesis ofthe monomers according to the invention.
