Abstract

Highly sulfated oligosaccharides in the form of hexasaccharide and octasaccharide compounds which have antiproliferative activity with respect to smooth muscle cells are useful in treatment of conditions characterized by unwanted smooth muscle cell proliferation such as a result of trauma or disease states such as asthma, congestive heart failure and hypertension. The oligosaccharides have increased ability to inhibit the proliferation of smooth muscle cells and decreased ability to act as an anticoagulant as compared with commercial heparin and/or unseparated fragments of heparin.
