  Synthesis of potential C27-intermediates in bile acid biosynthesis and their deuterium-labeled analogs

  摘要：

  In connection with studies of alternative pathways in bile acid biosynthesis, potential intermediates in a pathway starting with 27-hydroxylation of cholesterol have been prepared in natural and deuterated forms. Established methods were used to prepare 27-hydroxycholesterol and 3beta-hydroxy-5-cholestenoic acid. Clemmensen reduction of kryptogenin in unlabeled and deuterated solvents yielded 27-hydroxy-cholesterol and 16-oxo-5-cholestene-3beta,27-diol, which were separated by adsorption chromatography on Unisil. The labeled 27-hydroxycholesterol and 3beta-hydroxy-5-cholestenoic acid derived from it consisted of molecules with seven (50%), six (20%), and eight (20%) deuterium atoms, and unlabeled molecules were not detected. The acetates of 27-hydroxycholesterol and methyl 3beta-hydroxy-5-cholestenoate were 7alpha-hydroxylated in a copper-catalyzed reaction with tert-butylperbenzoate, and the products were purified by chromatography on Unisil. The 7beta-epimers were obtained as side products. Labeled 3beta,7alpha-dihydroxy-5-cholenoic acid was prepared in the same way from 3beta-hydroxy-5-[2,2,4,4,23-H-2(5)-cholenoic acid. The 3-oxo-DELTA4 analogs of the 3beta-hydroxy-DELTA5 compounds were prepared by oxidation with cholesterol oxidase. The labeled products had the same isotopic composition as the starting materials. Gas chromatographic retention indices and mass spectral characteristics of the trimethylsilyl ether derivatives of the neutral steroid and the methylated acids are given for all compounds.

  Disclosed is a group of chimeric antigen receptors (CARs) consisting of two, three or four CAR molecules, wherein the members of the group of CARs can be different or identical in their amino acid sequences to one another, and wherein each of the CAR molecules of the group comprise at least a transmembrane domain and an ectodomain comprising either an antigen binding moiety or a binding site to which another polypeptide is able to bind, wherein the another polypeptide comprises an antigen binding moiety; wherein each CAR molecule of the group comprises at least one dimerization domain, wherein this dimerization of a pair of dimerization domains is either induced by a regulating molecule and optionally reduced by another regulating molecule, or occurs in the absence of a regulating molecule and is reduced by a regulating molecule, and wherein the ectodomain of each CAR molecule of the group in its prevalent conformation is free of cysteine amino acid moieties which are able to form intermolecular disulphide bonds with other CAR molecules of the group, respectively, and wherein the antigen binding moieties of the CAR molecules of the group and of the other polypeptides being able to bind to the CAR molecules of the group are either specific for one target antigen or for a non-covalent or a covalent complex of different target antigens.
