We report on the THz generation and optical characterizations such as index of refraction, absorption coefficients of indigenously grown, potentially NLO active N-benzyl-2-methyl-4-nitroaniline (BNA) single crystals grown from four different solvents such as N, N dimethylformamide (DMF), Methano...

It is supposed that the main cytotoxicity mechanism of antitumour aziridinyl-substituted benzoquinones is their two-electron reduction to alkylating products by NAD(P)H:quinone oxidoreductase (NQO1, DT-diaphorase, EC 1.6.99.2). However, other possible cytotoxicity mechanisms, e.g., oxidative str...
