    The anti-ulcer drug sucrose octasulfate (SOS) binds to fibroblast growth factors (FGFs), proteins which stimulate the growth and differentiation of several cell types, including stomach epithelial cells. It is believed that SOS stabilizes FGFs against acid denaturation in the stomach, thus enhancing their ability to stimulate healing of ulcerated tissue. SOS binds to the same site on FGF as heparin and other proteoglycans; in vivo, FGF must bind to cell-surface proteoglycans or to heparin before it can interact with FGF receptors and stimulate growth. The details of this process are not understood.
