摘要:
A compound of formula I ##STR1## wherein R stands for a straight or branched, saturated or unsaturated alkyl group containing from 4 to 12 carbon atoms optionally substituted with a hydroxy group, and possibly containing a ring structure, and in which at least one of the carbon atoms not bearing hydroxyl group is substituted with one or more halogen atoms or an azido group; and prodrugs of I in which one or more of the hydroxy groups are masked as groups which can be reconverted to hydroxy groups in vivo, in pure form or in mixtures. The compounds show antiinflammatory and immunomodulating effects as well as strong activity in inducing differentiation and inhibiting undesirable proliferation of certain cells. The compounds are prepared by oxidizing 1(S),3(R)-bis-(tert-butyldimethylsilyloxy)-20(S)formyl-9,10-seco-pregna-5(E),7(E),10(19)-triene, reducing the resulting product; alkylating the reduction product and then subjecting the alkylated product to triplet-sensitized photoisomerization.

摘要:
Composite material, where the matrix material and the additive are held together by covalently or non-covalently bound ligands. The linker unit between matrix and additive has the structure Ligand1-LinkerL-Ligand 2, wherein Ligand1 and Ligand2 are a bond or a chemical entity that is capable of binding covalently or non-covalently to a structural entity, such as a polymer matrix or the additive (ex. CNT, graphene, carbon nanofiber, etc), and LinkerL is a chemical bond or entity that links Ligand1 and Ligand2.

摘要:
Novel compounds carrying ligands capable of binding to counter receptors on relevant target cells are disclosed. The compounds possess a number of advantageous features, rendering them very suitable for a wide range of applications, including use as detection systems, detection of relevant target cells as well as a number of other methods. In particular, novel MHC complexes comprising one or more MHC molecules are disclosed. The affinity and specificity of the MHC-peptide complexes are surprisingly high. The possibility of presenting to the target cells a plurality of MHC-peptide complexes makes the MHC complexes according to the present invention an extremely powerful tool e.g. in the field of therapy and diagnosis. The invention generally relates to the field of therapy, including therapeutic methods and therapeutic compositions. Also comprised by the present invention is the sample-mounted use of MHC complexes and MHC multimers.
