Özet
Considering the selective pharmacological activity of chiral drugs, it is important to develop new chiral materials to synthesize them. In this work, two new chiral MOFs (UiO-66@Np and UiO-66@Ib) were prepared by the covalent attachment of the chiral compounds (S-naproxen and S-ibuprofen) to the amine-functionalized Zr-MOF (UiO-66-NH2). Then, Candida rugosa lipase (CRL) was immobilized on these chiral MOFs to fabricate two new biocomposites (UiO-66@Np@CRL and UiO-66@Ib@CRL) as effective biocatalysts, which enable significant enhancement in the catalytic activity and enantioselectivity of lipase. The FTIR, SEM, EDX, TGA, and PXRD analyses were carried out to confirm the formation of the biocomposites. The catalytic performances of the biocomposites (UiO-66@Np@CRL and UiO-66@Ib@CRL) were evaluated in the typical hydrolysis of p-nitro-phenyl palmitate (p-NPP) and the catalytic enantioselective hydrolysis of (R,S)-naproxen methyl ester. Under optimal conditions, UiO-66@Np@CRL showed a higher enantiomeric excess of the substrate (ees) value and a 98 % and 50 % conversion rate, respectively, than that of UiO-66@Ib@CRL. Besides, an excellent enantioselectivity (E) value of 458 was obtained in the presence of the biocomposite (UiO-66@Np@CRL). In addition, it was observed that the catalytic activity, conversion rate and ees value of this composite (UiO-66@Np@CRL) remained almost unchanged in reuse after 6 months. The results showed that in enantioselective reactions, the highest conversion and enantioselectivity could be achieved when the chiral compound bound to the MOF and the model compound used are the same.
