This invention relates to esterified polysulfated cyclodextrins, their use in treating diseases and conditions which are characterized by excessive smooth muscle cell (SMC) proliferation such as restenosis and a pharmaceutical composition thereof. The compounds useful in this invention are represented by Formula (I), where: M is a pharmaceutically acceptable cation; p is 1 or 2; q is n/2 when p is 2 and q is n when p is 1; R is selected from the group consisting of C1-C12 lower alkyl, C3-C12 cycloalkyl, and aryl or heteroaryl optionally substituted with 1-3 substituents independently selected from halogen, C1-C12 lower alkyl or C1-C12 alkoxy; and n is an integer from 6 - 8, representing .alpha.-cyclodextrin (n = 6), .beta.-cyclodextrin (n = 7), and .gamma.-cyclodextrin (n = 8).
L'invention porte sur des cyclodextrines polysulfatées estérifiées, leur utilisation dans le traitement de maladies et d'états tels que la resténose caractérisés par une prolifération excessive des cellules des muscles lisses, et sur une préparation pharmaceutique la contenant. Les principes actifs de l'invention sont représentés par la formule (I) dans laquelle: M est un cation pharmacocompatible; p est 1 ou 2; q est n/2 quand p est 2, et q est n quand p est 1; R est choisi dans un groupe consistant en un alkyle inférieur C¿1?-C¿12?; un cycloalkyle C¿3?-C¿12?; et un aryle ou un hétéroaryle facultativement substitué par des substituants sélectionnés indépendamment parmi un halogène, un alkyle inférieur C¿1?-C¿12? ou un alcoxy C¿1?-C¿12?; et n est un entier de 6 à 8 représentant une .alpha.-cyclodextrine (n = 6), une .beta.-cyclodextrine (n = 7) et une .gamma.-cyclodextrine (n = 8).
