Abstract

In this study, axially substituted silicon (IV) phthalocyanine complexes containing pyrimidine-substituted Schiff bases were synthesized and characterized. The Schiff bases (Pyr-1 and Pyr-2) were synthesized through a condensation reaction between pyrimidine derivatives and appropriate aldehydes, followed by their coordination with silicon (IV) to form the corresponding phthalocyanine complexes (Pyr-1-SiPc and Pyr-2-SiPc). The synthesized Schiff bases (Pyr-1 and Pyr-2) and silicon (IV) phthalocyanine derivatives (Pyr-1-SiPc and Pyr-2-SiPc) were subsequently tested in vivo for their inhibitory effect on the enzymes acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). A substantial number of these compounds exhibited pronounced inhibitory activity against both enzymes. Notably, among the phthalocyanines and their precursor compounds, the most intriguing were identified as submicromolar selective inhibitors of AChE and BChE, with IC₅₀ values of 4.26 μM and 6.46 μM, respectively.

期刊介绍： All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
