Claim:
A biaromatic vitamin D analogue having the following general formula (I): in which A-Q is an unsubstituted alkyne or alkene bond, a —CH 2 —O— radical, a —CH 2 —S— radical or a —CH 2 —CH 2 — radical; B-T is an unsubstituted alkyne or alkene bond, a —CH 2 —S—, —CH 2 —O—, —CH 2 —CH 2 — or —CH 2 —NR 6 — radical; R 6 is as defined below; R 1 and R 2 , which may be identical or different, are each a hydrogen atom, a linear or branched alkyl radical having 1 to 5 carbon atoms, or the radical —CF 2 R 5 ; R 3 is a linear or branched alkyl radical having 1 to 5 carbon atoms, or the radical CF 2 R 5 ; R 5 is as defined below; the radicals R 4 , which may be identical, are each a hydrogen atom, a linear or branched alkyl radical having 1 to 6 carbon atoms, or the radical —CF 2 R 5 , with the proviso that the two radicals may also form a saturated ring having 4 to 7 carbon atoms, or a saturated heterocycle; R 5 is a fluorine atom, a hydrogen atom, or a radical —CF 3 ; R 6 is a hydrogen atom, a linear or branched alkyl radical having 1 to 6 carbon atoms, or the radical —C(O)R 8 ; and R 8 is a hydrogen atom, or a linear or branched alkyl radical having 1 to 6 carbon atoms; and the optical and geometric isomers and salts thereof.
