Article Title: Discovery of a new function of curcumin which enhances its anticancer therapeutic potency

doi: 10.1038/srep30962

Figure Lengend Snippet: ( a ) 1 H-NMR spectra of PC 4 nanoassembly measured in D 2 O at pH 7.4, pH 6.5, and pH 5.5, respectively. ( b ) Relative peak intensity of curcumin in the nanoassembly measured in D 2 O at pH 5.5, pH 6.5, and pH 7.4, respectively. ( c ) pH-sensitive membrane-lytic activity of CCM nanoassemblies after 2 h of incubation with seep erythrocyte at pH 5.5, pH 6.5, and pH 7.4, respectively. Values are average of three separate experiments in triplicate and are expressed as mean ± SD.

Article Snippet: Characterization of the obtained CCM amphiphiles were carried out by 1 H-NMR measurement (JEOL, ECA-500, solvent: CDCl3 ) and gel permeation chromatography (GPC) (JASCO, HPLC LC-2000Plus, column: TSKgel® , detector: RI, standard: PEG, eluent: DMSO dissolving 10 mM LiBr).
