© 2020 John Wiley & Sons, Ltd.In this work, peripheral or nonperipheral tetra-[4-(9H-carbazol-9-yl)phenoxy] substituted cobalt(II), manganese (III) phthalocyanines were synthesized for the first time. Their acetylcholinesterase from Electrophorus electricus (AChE), butyrylcholinesterase equine serum (BuChE), and α-glucosidase Saccharomyces cerevisiae inhibition were investigated spectrophotometrically. Finally, in vitro cytotoxicities of the compounds were investigated on human neuroblastoma (SH-SY5Y) cell line using MTT cell viability assay. The compounds inhibited to enzymes in the range of 7.39 ± 0.25–35.29 ± 2.49 μM with IC50 values for AChE and 14.38 ± 0.66–58.02 ± 4.94 μM for BuChE as compared with galantamine, which used as a positive control. For α-glucosidase, all compounds had stronger inhibition action than acarbose according to the IC50 values. The IC50 values of N-Co and N-Mn were found to be 3.05 ± 0.10 and 15.82 ± 1.85 μM, respectively. The results of cytotoxicity showed that the IC50 values were above 100 μM showing the compounds had low cytotoxic action against SH-SY5Y cell line for 24 h. Overall, carbazole substituted nonperipheral compounds can be considered as a potential agent for the treatment of Alzheimer's diseases and diabetes mellitus.
