“…(2021) investigated the antioxidant activity of zinc phthalocyanine. The compound exhibited radical scavenging activity at all the tested concentrations and the percentage of the DPPH radical scavenging activity increased from 19.92 to 66.77 % as the concentration enhanced from 100 μg/mL to 500 μg/mL [34] .

In this study, three new axially disubstituted silicon phthalocyanines (SiPc1-3) and their quaternized phthalocyanine derivatives (QSiPc1-3) were prepared and characterized. The biological properties (antioxidant, antimicrobial, antibiofilm, and microbial cell viability activities) of the water-soluble silicon phthalocyanines were examined, as well. A 1 % DMSO diluted with pure water was used as a solvent in biological activity studies. All the compounds exhibited high antioxidant activity. They displayed efficient antimicrobial and antimicrobial photodynamic therapeutic properties against various microorganisms, especially Gram (+) bacteria. Additionally, they demonstrated high antibiofilm activities against S. aureus and P. aeruginosa. In addition, 100 % bacterial reduction was obtained for all the studied phthalocyanines against E. coli viable cells. Besides, the DNA cleavage and binding features of compounds (QSiPc1-3) were studied using pBR322 DNA and CT-DNA, respectively. Furthermore, the human topoisomerase I enzyme inhibition activities of compounds QSiPc1-3 were studied. Anticancer properties of the water-soluble compounds were investigated using cell proliferation MTT assay. They exhibited anticarcinogenic activity against the human colon cancer cell line (DLD-1). Compounds QSiPc1 and QSiPc3 displayed a high anticarcinogenic effect on the DLD-1 cell line. The obtained results indicated that all the studied compounds may be effective biological agents and anticancer drugs after further investigations.

“…This activity has been attributed to the resonance of π-electrons in porphyrins and the central zinc ion, as well as reduction mechanism by the d z 2 orbital of the central copper ion. 23,24 Therefore, it was demonstrated that the Zn-PP cream had great potential as a broad-spectrum sunscreen, strongly preventing UV-A radiation.…”
