CRYSTAL STRUCTURE OF HUMAN THYMIDINE PHOSPHORYLASE IN COMPLEX WITH A SMALL MOLECULE INHIBITOR

Overview

Human thymidine phosphorylase (HTP), also known as platelet-derived, endothelial cell growth factor (PD-ECGF), is overexpressed in certain, solid tumors where it is linked to poor prognosis. HTP expression is, utilized for certain chemotherapeutic strategies and is also thought to, play a role in tumor angiogenesis. We determined the structure of HTP, bound to the small molecule inhibitor 5-chloro-6-[1-(2-iminopyrrolidinyl), methyl] uracil hydrochloride (TPI). The inhibitor appears to mimic the, substrate transition state, which may help explain the potency of this, inhibitor and the catalytic mechanism of pyrimidine nucleotide, phosphorylases (PYNPs). Further, we have confirmed the validity of the HTP, structure as a template for structure-based drug design by predicting, binding ... [(full description)]
