Research Abstract |
Vitamin K_2 and imidazoles showed weak tumor-specificity against human oral squamous cell carcinoma cell lines, whereas benzaldehyde, tetraisoquinolines and cyclic α,β-unsaturated ketones showed much higher tumor-specificity. These compounds induced autophagic cell death characterized by destruction of mitochondrial structure, but autophagy inhibitors failed to prevent the induced cell death. There was a good correlation between their cytotoxicity and chemical descriptors such as hydrophobicity, surface area, volume and width of the molecules.
