Laccase-catalysed azide-alkyne cycloadditions: Synthesis of benzothiazole and benzimidazole fused 1,2,3-triazole derivatives by copper containing oxidoreductase enzymes
A new approach for synthesizing triazole rings through the application of laccases, copper containing oxidoreductase enzymes is outlined. A series of benzothiazoles and benzimidazoles-functionalized alkynes were initially synthesized utilizing a biocatalysis laccase-based approach. The resultant alkynes were further treated with aryl azides in a 1,3-dipolar cycloaddition reaction facilitated by laccase enzymes to obtain 1,2,3-triazole-fused benzothiazoles and benzimidazoles.</p
Spherezyme particles consisting of various percentage combinations of lipase and BSA
Lipase specific activity (on -nitrophenyl palmitate) is represented as a function of lipase mass as opposed to total protein mass. Data was generated from particles that were formed using 40 μl glutaraldehyde-EDA mix as a cross-linker and nonoxynol-4 as the surfactant.<p><b>Copyright information:</b></p><p>Taken from "Spherezymes: A novel structured self-immobilisation enzyme technology"</p><p>http://www.biomedcentral.com/1472-6750/8/8</p><p>BMC Biotechnology 2008;8():8-8.</p><p>Published online 31 Jan 2008</p><p>PMCID:PMC2266724.</p><p></p
Activity of a spherezyme particles comprised of a combination of enzymes (lipase and Denilitelaccase) cross-linked with glutaraldehyde: PNPB – -nitrophenyl butyrate; PNPP – -nitrophenyl palmitate (A)
The ratio of -nitrophenyl palmitate to -nitrophenyl butyrate activity of these combined enzyme particles can be compared to free lipase and lipase spherezyme particles (B).<p><b>Copyright information:</b></p><p>Taken from "Spherezymes: A novel structured self-immobilisation enzyme technology"</p><p>http://www.biomedcentral.com/1472-6750/8/8</p><p>BMC Biotechnology 2008;8():8-8.</p><p>Published online 31 Jan 2008</p><p>PMCID:PMC2266724.</p><p></p
