Description of (R)-(+)-Etomoxir sodium salt

(R)-(+)-Etomoxir sodium salt est une petite molécule développée pour le traitement des maladies métaboliques et cardiovasculaires, présentant une puissance nanomolaire envers CPT-1a et CPT-1b après conversion enzymatique en l'inhibiteur actif etomoxiryl-CoA (IC50 = 0,01-0,70 µM)[1-3].

L'Etomoxir (50 µM ETO ; un jour sur deux pendant 10 jours) réduit la prolifération des cellules T co-stimulées par CD28 sans affecter la différenciation des effecteurs des cellules T [4]. De faibles concentrations (3 µM, 24 h) d'Etomoxir inhibent efficacement CPT-1 mais n'affectent pas la polarisation des macrophages M(IL-4). Des concentrations élevées d'Etomoxir (200 µM) inhibent la polarisation M(IL-4) indépendamment de l'activité de CPT-1 dans les cellules BMDM [5]. De plus, l'effet de l'Etomoxir sur la différenciation et la fonction des cellules T est indépendant de l'expression de Cpt1a [6].

L'Etomoxir (40 mg/kg ; i.p. ; un jour sur deux pendant 20 jours) a supprimé la croissance des cellules cancéreuses de la vessie humaine (BCa) in vivo [7]. L'Etomoxir (i.p. ; 1 mg/kg ; deux fois par semaine) inhibe de manière significative la diminution de la densité minérale osseuse (DMO) et de la résistance à la rupture osseuse chez les souris db/db et nourries avec un régime riche en graisses (HF), et supprime la réduction des ostéoblastes différenciés à partir des BMSCs [8].
