Abstract
In the present study, a number of new dispirobino and dispiroansa spermine derivatives of cyclotriphosphazene (8–10, 13) were synthesized and characterized by elemental analysis, mass spectrometry, 1H and 31P NMR spectroscopy. At first, in vitro cytotoxic activity of cyclotriphosphazene compounds (1–14) against HT-29 (human colon adenocarcinoma), Hep2 (Human epidermoid larynx carcinoma), and Vero (African green monkey kidney) cell lines was investigated. Our study showed that most of these compounds stimulate apoptosis and they have cytotoxic effects for HT-29 and Hep2 cells. Additionally, these compounds (1–14) were investigated for their antibacterial activity against gram-positive (Staphylococcus aureus), gram-negative (Escherichia coli, Pseudomonas aeruginosa) bacteria and for their antifungal activity against Candida albicans, and were shown to be inactive.
