Definitions
- This invention relates to the use of substituted benzylmaltosides as smooth muscle cell proliferation inhibitors and as therapeutic compositions for treating diseases and conditions which are characterized by excessive smooth muscle proliferation such as restenosis.
- glycosaminoglycans heparin and heparan sulfate are endogenous inhibitors of SMC proliferation, yet are able to promote endothelial cell growth (Castellot, J.J. Jr.; Wright, T. C; Karnovsky, M.J. Seminars in Thrombosis and Hemostasis 1987, 13, 489).
- heparin, heparin fragments, chemically modified heparin, low molecular weight heparins, and other heparin mimicking anionic polysaccharides may be compromised due to other pharmacological liabilities (excessive bleeding arising from anticoagulation effects, in particular) coupled with heterogeneity of the various preparations (Borman, S. Chemical and Engineering News, 1993, June 28, 27).
- WO 96/14325 discloses acylated benzylglycosides as smooth muscle cell proliferation inhibitors.
- the compounds of the present invention differ in that the substituents on the carbohydrate backbone are substantially different.
- Patent numbers US 5,498,775, WO96/14324, and US 5,464,827 describe polyanionic benzylglycosides or cyclodextrins as smooth muscle cell proliferation inhibitors for treating diseases and conditions which are characterized by excessive smooth muscle proliferation, ⁇ -cyclodextrin tetradecasulfate has been described as a smooth muscle cell proliferation inhibitor and as an effective inhibitor of restenosis (Reilly, C.F.; Fujita, T.; McFall, R. C; Stabilito, I. I.; Wai-se E.; Johnson, R. G. Drug Development Research 1993, 29, 137).
- US 5019562 discloses anionic derivatives of cyclodextrins for treating pathological conditions associated with undesirable cell or tissue growth.
- WO 93/09790 discloses antiproliferative polyanionic derivatives of cyclodextrins bearing at least 2 anionic residues per carbohydrate residues.
- Wetsberger (EP 312087 A2 and EP 312086 A2) describes the antithrombotic and anticoagulant properties of sulfated bis-aldonic acid amides.
- US 4431637 discloses polysulfated phenolic glycosides as modulators of the complement system.
- the compounds of the present invention differ from this prior art in that the compounds (a) are benzylmaltosides which bear no structural resemblance to heparin, sulfated cyclodextrins, or to sulfated lactobionic acid dimers, (b) contain no more than two contiguous sugar residues (disaccharide) and (c) are of a defined structure.
