Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to substituted benzyls as smooth muscle cell proliferation inhibitors and as therapeutic compositions for treating diseases and conditions such as restenosis characterized by excessive smooth muscle proliferation. It relates to the use of glycosylamide.

BACKGROUND OF THE INVENTION [0002] All forms of vascular remodeling, such as angioplasty and venous bypass, are directed at damage that ultimately leads to smooth muscle cell (SMC) proliferation and subsequent deposition of large amounts of extracellular matrix. Produce a response (Clowes, AW)

And arteriosclerosis after transplantation (Isik, FF); McDonald, TO; Ferguson, M .; Yamanaka, E .; It is also a central process in the pathogenesis of Gordon, American Journal of Pathology (Am. J. Pathol.), 1992, 141, 1139). In the case of restenosis after angioplasty, a clinically relevant solution to regulate SMC proliferation by pharmacological interference has remained elusive (Herman, J.P.R.). , JPR); Hermans, WRM; Voss, J .; Serois, PW, Drugs, 1993, 4, 18, and 249). Selective SM
Successful approaches to C growth inhibition must not interfere with endothelial cell repair or the normal growth and function of other cells (Weissburg, P.

M (Shanahan, CM); Metcalfe, JC, Cardiovascular Res., 1993, 27, 1191).

[0003] Glycosaminoglycan heparin and heparan sulfate are endogenous inhibitors of SMC proliferation and can also promote endothelial cell proliferation (Castellot, JJJr.); Wright, T Sea
.C.); Karnovsky, MJ, Seminars in
Seminars in Thrombosis and Hemostasis
), 1987, 13,489). However, the full clinical utility of heparin, heparin fragments, chemically modified heparin, low molecular weight heparin, and other heparins that mimic anionic polysaccharides has been linked to other pharmacology linked to the heterogeneity of various formulations. Trends (especially,

The compounds of the present invention differ in that (a) the sugar has anomeric amide, (b) the substituent on the benzyl group is different, and (c) the application (smooth muscle growth inhibition) is different.

US Pat. No. 5,498,775, PCT Application Publication No. WO 96/14324 and US Pat.
No. 4,64,827 describes polyanionic benzyl glycosides or cyclodextrins as smooth muscle cell proliferation inhibitors for treating diseases and conditions characterized by excessive smooth muscle proliferation. β-cyclodextrin tetradeca sulfate has been described as a smooth muscle cell proliferation inhibitor and an effective inhibitor of restenosis (Reilly, CF; Fujita, T.); McFall, RC; Stabilite, Eye
lito, II); Wai-se, E .; Johnson, Johns
on, RG), Drug Development Research (Drug Development Research)
h), 1993, 29, 137). U.S. Patent No. 5,019,562 discloses anionic derivatives of cyclodextrin for treating pathological conditions associated with unwanted cell or tissue growth. PCT Application Publication No. WO 93/09790 discloses a growth inhibiting polyanionic derivative of cyclodextrin having at least two anionic residues per sugar residue. Meinetsberger (EP 312087 A2 and EP 312086 A2) describes the antithrombotic and anticoagulant properties of sulfated bis-aldonic amides. U.S. Pat. No. 4,431,637 discloses polysulfated phenolic glycosides as modulators of the complement system. The compounds of the present invention are (a) benzylglycosylamides which have no structural similarity to heparin, sulfated cyclodextrin, or sulfated lactobionic acid dimer; It differs from all the prior art in that it has adjacent sugar residues (is a disaccharide), (c) has a well-defined structure, and (d) is not sulfated.
