Development Of Novel Peptide-Doxorubicin Conjugates For Targeting Triple-Negative Breast Cancer, Azam Saghaeidehkordi
Pharmaceutical Sciences (PhD) Dissertations
Triple-negative breast cancer (TNBC) is the most aggressive and difficult to treat subtype of breast cancer. Chemotherapy is an active treatment option in combination with other treatments; however, the side effects limit the effective therapeutic dose. To selectively target the cancer cells, I have synthesized three peptide-drug conjugates (PDCs) to specifically target the TNBC cells. The first PDC contains peptide 18-4 with an additional cysteine in the N-terminal (NH2- CWxEAAYQrFL-CONH2) linked to aldoxorubicin (Aldox), a modified version of a common chemotherapy drug doxorubicin (Dox). The cytotoxicity of the PDC and free Dox (positive control) were assessed against MDA-MB-231, MDA-MB-468, and …
