Abstract

Presently, trastuzumab (Herceptin), that will be an anti-her2 antibody, is one of the key drugs. There is certainly evidence indicating that conjugation of trastuzumab with chemotherapy drugs, such as for instance doxorubicin (DOX), for multiple objectives could be far better. However, incomplete penetration into tumors happens to be noted for many conjugates. When compared with an antibody, peptides may represent a appealing alternative. For HER2, the same effectiveness was seen for the 12-amino-acid anti-HER2 peptide mimetic Y CDGFYA CYMDV-NH2 (AHNP, disulfide-bridged) and trastuzumab that is full-length. Thus, a peptide, GPLGLAGDDY CDGFYA CYMDV-NH2, which includes AHNP and an MMP-2 linker that is cleavable, was initially designed, followed closely by conjugation with DOX via a glycine residue at the N-terminus to form a novel DOX-peptide conjugate MAHNP-DOX.
