GLUCOSE-SENSITIVE PEPTIDE HORMONES

The present invention relates to a conjugate of the formula P-L-I, wherein P is a peptide hormone effecting the metabolism of carbohydrates in vivo, L is a hydrolysable linker molecule consisting of Lp and Lj, and I is a molecule capable of inhibiting the effect of the peptide hormone P on the metabolism of carbohydrates in vivo. Under in vivo conditions, the conjugate is the major compound. When the concentration of glucose increases in v/vo,the concentration of the peptide hormone effecting the metabolism of carbohydrates in vivo also increases.
