First Claim
1. Vitamin D derivatives corresponding to the following formula I ##STR16## in which R1 denotes a substituted alkyl group having 1 to 15 carbon atoms wherein the substituent isan hydroxyl, ester or ether at one or more positions;
- a methyl or ethyl group at one or more positions;
a halogen or a plurality of halogens at one or more positions;
one or more carbon atoms added;
a substituent formed by replacing one or more carbon atoms of said alkyl group by oxygen, nitrogen or sulfur atoms;

Abstract
Vitamin D derivatives corresponding to the following formula I ##STR1## in which R1 denotes a substituted alkyl group having 1 to 15 carbon atoms, in particular the side chains of vitamin D2 (C20 to C28) or D3 (C20 to C27), or these same chains partially modified,
Y denotes H or OH or groups derived from the latter such as ester and ether;
X denotes
an alkyl chain, in particlar of 1 to 6 carbon atoms, optionally substituted at different points by one or more functional group (s)
an unsaturated alkyl chain having one or more carbon-carbon double or triple bond(s), it being possible for these chains, in addition, to bear functional groups, or
an aromatic or heteroaromatic ring, optionally substituted with halogens, one (or more) hydroxyl, amine, formyl carboxyl, thiol, cyano or nitro group(s), or alternatively groups derived from these latter, such as ether, ester, acetal or amide, or
a halogen, a cyano, sulfoxide, sulfone, hydroxyl, thiol or amine group, or alternatively derivatives of these latter, such as ether, ester, amine and hydrazine;
R2 denotes a methyl group and R3 an H, or R2 is H and R3 is methyl, or R2 and R3 are H, or alternatively R2 and R3 together denote a methylene group=CH2.
The present invention relates to the therapeutic application of these derivatives.
The present invention also relates to a method for preparing these derivatives; and to an antigen prepared by the covalent binding of these derivatives with an immunogenic carrier protein and antibodies prepared using this antigen. Finally, the present invention also relates to tracers consisting of the conjugation of a derivative according to the invention with a labeling component such as an enzyme or an iodinated molecule, as well as to an assay method for metabolites of vitamin D comprising the use of these tracers as a reagent.
