Chelator Fragment Library

Chelator Fragments LibraryFragment-based lead design (FBLD) could be used to identify new metal-binding groups for metalloenzyme inhibitors. Several small-molecule chelators have been shown to effectively inhibit metalloproteins, therefore the design,

synthesis, and use of general fragment libraries based on metal chelators for FBLD applications is of great interest. Chelators demonstrate binding affinities suitable for FBLD screening and provide a diverse range of molecular platforms from which to develop lead compounds. Also, the propensity for chelators to bind metal ions allows for better prediction of their probable binding position within a protein active site in the absence of experimental structural data of the complex.
