摘要:
The present invention relates to a prodrug or a pharmaceutically acceptable salt thereof, comprising a drug linker conjugate D-L, wherein D being a biologically active moiety containing an aromatic amine group is conjugated to one or more polymeric carriers via dipeptide-containing linkers. Such carrier-linked prodrugs achieve drug releases with therapeutically useful half-lives. The invention also relates to pharmaceutical compositions comprising said prodrugs and their use as medicaments.
摘要:
The present invention relates to binding surfaces for the immobilization of ligands, ligand surfaces and structured surface arrays which present a plurality of identical or different ligands. The invention further relates to a process for the production and the use of such surfaces and to specific binder molecules which can be used for the preparation thereof.
摘要:
The present invention relates to sensors for the detection of molecular interactions between immobilized ligands and non-immobilized interaction partners (receptors). These surfaces use novel ligand-anchor conjugates which allow highly specific interaction with suitable interaction partners. Furthermore the invention relates to methods of providing the sensing surface and in particular methods of synthesising the ligand-anchor conjugates (LAC).
摘要:
A continuous process for the preparation of alkoxypolysiloxane in which silane or a silane mixture and a mixture of hydrogen chloride-containing alcohol and water is fed continuously into the lower region of preferably cylindrical stirred reactor, the reaction product formed together with excess hydrogen chloride-containing alcohol is drawn off continuously after residence time of 30 to 180 minutes at the upper end of the reactor and the undissolved, gaseous portion of hydrogen chloride is carried off at the head of the reactor, the temperature of the reaction mixture or the reaction product, as it flows through the reactor, being raised from a range of -17.degree. to +30.degree. C. to range of +30.degree. to +80.degree. C., the temperature gradient having to be at least 10.degree. C., and the excess alcohol and dissolved hydrogen chloride being removed outside of the reactor in a known manner from the reaction product formed, and the hydrogen chloride-containing alcohol obtained while working up to reaction product being recycled to the reactor. The invention furthermore relates to an apparatus which is particularly suitable for implementing the process.
摘要:
The invention relates to a process for the preparation of heat-curable resins, usable especially as electrically insulating resins, by the reaction of alkoxy siloxanes of the formula ##STR1## in which OR.sup.1 represents an alkoxy group of primary or secondary aliphatic alcohols with 1 to 4 carbon atoms,R.sup.2 represents an alkyl or a phenyl group,a has a value of 1.0 to 1.5,b has a value of 0.1 to 1.0; witha mixture of low molecular weight, multihydric alcohols consisting of(a) 25 to 95 mole percent of neopentylglycol hydroxypivalate, and(b) 75 to 5 mole percent of a low molecular weight, at least trihydric alcoholat temperatures of 80.degree. to 200.degree. C. The resins thus prepared can be utilized advantageously for the insulation of generators, transformers and the like. They possess high elasticity and excellent adhesion.
