According to the present invention compositions and methods are provided to prevent the pathogenic aspects of tissue trauma while preserving normal tissue repair mechanisms, based on the fact that these molecules abrogate the cascade of damage initiated by tissue trauma, while maintaining this the requisite healthy extracellular matrix economy. The composition for regulating the extracellular matrix economy, comprise a pharmaceutically effective amount of an effector in combination with a pharmaceutically acceptable carrier. Preferably, the effector is a quinazolinone derivative. More preferably, the quinazolinone derivative is a member of a group having formula (I), wherein R1 is a member of the group consisting of hydrogen, halogen, nitro, benzo, lower alkyl, phenyl, and lower alkoxy; R2 is a member of the group consisting of hydroxy, acetoxy, and lower alkoxy, and R3 is a member of the group consisting of hydrogen and lower alkenoxy; and pharmaceutically acceptable salts thereof; and n is either 1 or 2. Most preferably, the effector is Halofuginone and pharmaceutically acceptable salts thereof.

L'invention concerne des compositions et des procédé permettant d'éviter les aspects pathogènes de lésions tissulaires tout en préservant les mécanismes normaux de réparation tissulaire, et ceci grâce à l'annulation par ces molécules des détériorations entraînées par la lésion tissulaire sans pour autant affecter l'économie matricielle extracellulaire saine nécessaire. Les compositions permettent de réguler l'économie matricielle extracellulaire et renferment une quantité pharmaceutiquement efficace d'un effecteur combiné avec un support pharmaceutiquement acceptable. L'effecteur est, de préférence, un dérivé de quinazolinone qui est, de préférence, un membre d'un groupe de formule (I) dans laquelle R¿1? représente un membre du groupe constitué d'hydrogène, halogène, nitro, benzo, alkyle inférieur, phényle et alcoxy inférieur; R¿2? représente un membre du groupe constitué d'un hydroxy, acétoxy, et alcoxy inférieur et R¿3? représente un membre du groupe constitué d'un hydrogène et alkénoxy inférieur; et leurs sels pharmaceutiquement acceptables; et n est égal à 1 ou 2. L'effecteur est, de préférence, un Halofuginone et ses sels pharmaceutiquement acceptables.
