In this paper, axial 1,3-bis[4-(4-acetylpiperazin-1-yl)phenoxy]propanoxy and {2-[4-(4-acetylpiperazin-1-yl)phenoxy]ethoxy}ethoxy groups substituted silicon(IV) phthalocyanines ( PP-D-Si, PP-OH2-Si) and their quaternized derivatives (PP-D-SiQ, PP-OH2-SiQ) were synthesized and characterized. The acetyl -cholinesterase inhibition values of 1,3-bis[4-(4-acetylpiperazin-1-yl)phenoxy]propanoxy and {2-[4-(4-acetylpiperazin-1-yl)phenoxy]ethoxy}ethoxy groups substituted silicon(IV) phthalocyanines ( PP-D-Si, PP-OH2-Si) and their quaternized derivatives (PP-D-SiQ, PP-OH2-SiQ) were measured by IC50 that reduces enzyme activity to 50% refers to the concentration of inhibitor. The synthesis compounds were classified as silicon and their quaternized derivatives and tagged as PP-D-Si, PP-OH2-Si, PP-D-SiQ and PP-OH2-SiQ. Except for the result of PP-D-SiQ was 1.586 & PLUSMN; 0.129 mu M, the results were expressed as mM ranged between 0.553 and 3.626 mM. (c) 2022 Published by Elsevier B.V.
