Abstract

Five active metal-conjugated inhibitors (PMA, TDT, EPDTC, JMF1586 and JMF1600) bound with the 3C-like protease of severe acute respiratory syndrome (SARS)-associated coronavirus were analyzed crystallographically. The complex structures reveal two major inhibition modes: Hg²⁺-PMA is coordinated to C⁴⁴, M⁴⁹ and Y⁵⁴ with a square planar geometry at the S3 pocket, whereas each Zn²⁺ of the four zinc-inhibitors is tetrahedrally coordinated to the H⁴¹-C¹⁴⁵ catalytic dyad. For anti-SARS drug design, this Zn²⁺-centered coordination pattern would serve as a starting platform for inhibitor optimization.
