Formulation and characterization of a sortase a inhibitor-loaded PMMA bone cement.

ABSTRACT: A sortase A inhibitor (SrtA I)-loaded bone cement (SLBC) containing 1-(3,4-dichlorophenyl)-3-(dimethylamino)propyl-1-one hydrochloride (AEEK1) was reported. Compared with gentamicin-loaded bone cement (GS cement), which is a widely used antibiotic-loaded bone cement in cemented total joint replacement (TJR), SLBC demonstrated a significantly prolonged effective antibacterial duration against both Staphylococcus aureus (S. aureus) and methicillin-resistant S. aureus (MRSA). The quasi-static compressive strength, maximum polymerization temperature, and setting time of SLBC were within the limits stated in the ISO 5833 standard and comparable to the corresponding values of GS cement. In vitro and in vivo experimental results confirmed the biocompatibility of
