Photoinduced DNA cleavage by fullerene–lysine conjugate
摘要:
A novel water-soluble [60] fullerene-substituted lysine derivative 3 has been synthesized and characterized by elemental analysis. H-1 NMR. C-13 NMR and FAB-MS The synthetic procedure involved condensation of Boc-protected lysine with terephthaldehyde followed by 1,3-dipolar cycloaddition reaction with C-60 in the presence of sarcosine and finally deprotection of the amino group using trifluoroacetic acid. The synthesized compound 3 exhibited high DNA cleavage efficiency upon visible light irradiation in the presence of NADH (C) 2009 Elsevier Ltd. All rights reserved.
