Web1 apr. 2024 · OBJECTIVES: To measure the CE and MMP activities from human neutrophils and their ability to degrade dental methacrylate resin composite and dentinal collagen. Neutrophils' CE and MMP activities were measured using nitrophenyl-esters or fluorimetric MMP substrates, respectively. WebDiglycidyl ester 1 (134.1 mg) and methacrylic acid (3 equiv) were dissolved in 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) (0.5 mL). The mixture was agitated at 65 °C for 50 h under air in a sealed tube. The purification procedure used for FD yielded a colorless, highly viscous liquid as the crude product (210.6 mg, 95%).
