Cosmetic use of at least one salicylic acid derivative of following formula (I) in which L represents a linear or branched hydrocarbon radical comprising from 1 to 12 carbon atoms and having or not having one or more ethylenic unsaturations, and X represents a radical chosen from —OH and —CO2H, and also its cosmetically acceptable salts, its solvates, such as its hydrates, and its isomers, in a composition comprising a physiologically acceptable medium, as cosmetic agent intended to promote the desquamation of the skin and/or to stimulate epidermal renewal.

Synthesis of isonicotinoylhydrazones from anacardic acid and their in vitro activity against Mycobacterium smegmatis
Isonicotinoylhydrazones were synthesized from a natural product anacardic acid, a major constituent of cashew nut shell liquid. The unsaturated side chain in anacardic acid and its 5-nitro derivative were converted into C-8'-aldehydes by oxidative cleavage. C-8'-aldehydes are then coupled with isoniazid (an anti-TB drug) to obtain N-isonicotinoyl-N'-8-[(2'-carbohydroxy-3'-hydroxy) phenyl] octanal hydrazone (5) and N-isonicotinoyl-N'-8-[(2'-carbohydroxy-3'-hydroxy-6-nitro) phenyl] octanal hydrazone (6). These isonicotmoylhydrazones of anacardic aldehydes showed potent antimycobacterial activity against Mycobacterium smegmatis mc(2) 155. The synergistic studies of 5 and 6 with isoniazid showed more inhibitory activities than isoniazid alone. Compounds 5 and 6 also showed activity against Mycobacterium tuberculosis H(37)Rv.
