Cytotoxic and Antiproliferative Effects of Diarylheptanoids Isolated from Curcuma comosa Rhizomes on Leukaemic Cells

Abstract: Curcuma comosa belongs to the Zingiberaceae family. In this study, two natural compounds were isolated from C. comosa, and their structures were determined using nuclear magnetic resonance. The isolated compounds were identified as 7-(3,4-dihydroxyphenyl)-5-hydroxy-1-phenyl-(1E)-1-heptene (1) and trans-1,7-diphenyl-5-hydroxy-1-heptene (2). Compound 1 showed the strongest cytotoxicity effect against HL-60 cells, while its antioxidant and anti-inflammatory properties were stronger than those of compound 2. Compo… Show more

“…In Thailand, ginger family plants are widely used as traditional medicine for many treatments, such as to relieve stomachache and hemorrhoids, as an herbal compress for massage, to improve blood circulation, to relieve muscular pain, and as a honey balm. Moreover, the rhizomes of these plants are also used as spices and ingredients for cooking [ 2 ]. Essential oils from Zingiberaceous plants have been used for mosquito control [ 3 , 4 ].…”

“…This concentration was previously shown not to be toxic to peripheral blood mononuclear cells (PBMCs) [ 21 ]. In a previous report, DHH, referred to as compound 2 , did not induce hemolysis in red blood cells [ 17 ]. Thus, this concentration is presumed safe for normal human cells.…”

“…The MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay was used to determine the cytotoxicity of Kae-Lae extracts and active compounds on leukaemic cells. The method was described previously [ 40 ]. K562 (1.0 × 10 5 cells/mL), EoL-1 (3.0 × 10 5 cells/mL), and KG-1a (2.0 × 10 5 cells/mL) were added samples and then incubated for 48 h. The percentage of surviving cells was calculated using the following equation:…”
