Abstract

Two types of valproamide dipeptides ie valproic acid VPATyrTyr and VPAHisHis were synthesized via Fmoc solidphase peptide synthesis purified via reversedphase HPLC and characterized via 1H 13C NMR and ESI–MS to promote the interaction of valproic acid derivative with biological molecular The interactions of VPATyrTyr and VPAHisHis with DNA were investigated via UV–Vis absorption spectroscopy fluorescence spectroscopy and gel electrophoresis The results showed that both VPATyrTyr and VPAHisHis interacted with ctDNA through the groove binding mode and exhibited higher affinity for ctDNA compared with free VPA Therefore the valpromide derivatives modified by dipeptides have significant practical value in future studiesWe thank the National Natural Science Foundation of China No 21172054 and 21301050 the Innovation scientists and Technicians Troop construction projects of Zhengzhou city No 10LJRC174 and the Foundation of Education Department of Henan Province No 13B150947
