  • Publication number: 20030170240
    Abstract: The effects of endogenous insulin-like growth factor can be appreciated by administering compounds capable of increasing free IGF in living bodies. Compounds are described which can elevate the concentration of unbound IGF by converting endogenous IGF (insulin-like growth factor) into free, biologically active IGF or elevating the concentration of the complex of IGF and IGFBP (insulin-like growth factor binding protein) in living bodies. Medicaments can be prepared containing these compounds or these compounds may be used in methods for the prevention and or treatment of IGF-responsive diseases such as diabetes, amyotrophic lateral sclerosis, or osteoporosis.
