Activators of Cylindrical Proteases as Antimicrobials: Identification and Development of Small Molecule Activators of ClpP Protease
摘要:
CIpP is a cylindrical serine protease whose ability to degrade proteins is regulated by the unfoldase ATP-dependent chaperones. CIpP on its own can only degrade small peptides. Here, we used CIpP as a target in a high-throughput screen for compounds, which activate the protease and allow it to degrade larger proteins, hence, abolishing the specificity arising from the ATP-dependent chaperones. Our screen resulted in five distinct compounds, which we designate as Activators of Self-Compartmentalizing Proteases 1 to 5 (ACP1 to 5). The compounds are found to stabilize the CIpP double-ring structure. The ACP1 chemical structure was considered to have drug-like characteristics and was further optimized to give analogs with bactericidal activity. Hence, the ACPs represent classes of compounds that can activate CIpP and that can be developed as potential novel antibiotics.

The present invention is directed to activators of cylindrical proteases ("ACPs"), particularly ClpP, and the role thereof in the diagnosis and treatment of bacterial infections. A number of ACPs were identified that activate caseinolytic protease P ("ClpP"), which independently can only degrade small peptides. In the presence of ACPs, ClpP may be activated to allow it to degrade larger proteins, hence, abolishing the specificity arising from the ATP-dependent chaperones. Members of the ACPs were found to have bactericidal activity. As such, ACPs represent a new classes of compounds that can activate ClpP and that can be developed as potential novel antibiotics.
The technology described herein relates to treatments for tuberculosis which target the ClpP1P2 protease complex, including ClpC1. Further embodiments relate to assays and screens for modulators of the ClpP1P2 protease complex, including ClpC1.
