ABSTRACT:

FIELD OF THE INVENTION
The invention relates, as novel and useful industrial products, to biaromatic compounds. The invention also relates to the use of these novel compounds in pharmaceutical compositions intended for use in human or veterinary medicine, or alternatively in cosmetic compositions.
BRIEF DESCRIPTION OF THE INVENTION
The compounds according to the invention have pronounced activity in the fields of cell differentiation and proliferation, and find applications more particularly in the topical and systemic treatment of dermatological complaints associated with a keratinization disorder, dermatological (or other) complaints with an inflammatory and/or immunoallergic component, and dermal or epidermal proliferations, whether they are benign or malignant. These compounds can also be used in the treatment of degenerative diseases of connective tissue, to combat ageing of the skin, whether this is light-induced or chronological ageing, and to treat cicatrization disorders. Elsewhere, these compounds find an application in the ophthalmological field, in particular in the treatment of corneopathies.
The compounds according to the invention can also be used in cosmetic compositions for body and hair hygiene.
The compounds according to the invention can be represented by the general formula (I) below:
in which:
R
1
represents
(i)
the radical
—CH
3
(ii)
the radical
—CH

(iv)
the radical
—CO—R

,
(iv)
a radical -SR
5
,
R
5
having the meaning given below,
with the condition that at least one of the radicals R

it being understood that R
2
and R
3
, taken together, can form, with the adjacent aromatic ring, a 5- or 6-membered ring optionally substituted with methyl groups and/or optionally interrupted by an oxygen or sulphur atom,
with the condition that R
2
and R
3
, taken together, form, with the adjacent aromatic ring, a 5- or 6-membered ring optionally substituted with methyl groups and/or optionally interrupted by an oxygen or sulphur atom, when X represents the radical of formula (m) or (i), Y represents the radical of formula (a) with n=0, Ar represents the radical of formula (d), R
