    摘要: Small cell lung carcinoma cells (SCLC) contain gastrin releasing peptide (GRP) receptors. The response of the cells to GRP is rapid growth. We have found a group of peptide derivatives that act as GRP antagonists by blocking the binding of GRP to its receptor thereby inhibiting the growth of cells that are sensitive to the growth promoting activity of GRP.

    摘要: We have modified PE40 toxin by removing at least two of its four cysteine amino acid residues and have formed hybrid molecules containing modified PE40 linked to a cell recognition protein that can be an antibody, a growth factor, a hormone, a lymphokine, or another polypeptide cell recognition protein for which a specific cellular receptor exists whereby the modified PE40 toxin is directed to cell types having receptors for the cell recognition protein linked to the modified PE40.
