Development of a peptide-drug conjugate for prostate cancer therapy.

Abstract:

:TGX-221 is a highly potent phosphoinositide 3-kinase β (PI3Kβ) inhibitor that holds great promise as a novel chemotherapeutic agent to treat prostate cancer. However, poor solubility and lack of targetability limit its therapeutic applications. The objective of this present study is to develop a peptide-drug conjugate to specifically deliver TGX-221 to HER2 overexpressing prostate cancer cells. Four TGX-221 derivatives with added hydroxyl groups were synthesized for peptide conjugation. Among them, TGX-D1 exhibited a similar bioactivity to TGX-221, and it was selected for conjugation with a peptide promoiety containing a HER2-targeting ligand and a prostate specific antigen (PSA) substrate linkage. From this selection, the peptide-drug conjugate was proven to be gradually cleaved by PSA to release TGX-D1. Cellular uptake of the peptide-drug conjugate was significantly higher in prostate cancer cells compared to the parent drug. Moreover, both the peptide-drug conjugate and its cleaved products demonstrated comparable activities as the parent drug TGX-D1. Our results suggest that this peptide-drug conjugate may provide a promising chemotherapy for prostate cancer patients.
