Five dinuclear platinum(II) complexes with a novel chiral ligand, 2-(((1R,2R)-2-aminocyclohexylamino)methyl)phenol (HL), were designed, prepared and spectrally characterized. In vitro cytotoxicity of all the resulting platinum(II) compounds was evaluated against human HEPG-2, A549 and HCT-116 cell lines, respectively. Results indicated that all compounds showed positive biological activity. Par...

Multifunctional silica nano-vehicles (SiO2@indol-IL) and magnetic nanoparticles (Fe3O4@indol-IL) were constructed through the Schiff bases condensation of indole-3-carboxaldehyde and 4-acetyl-N-allyl pyridinium chloride (ILs) with the amine groups of silica and magnetic nanoparticles. SiO2@indol-IL can inhibit the proliferation of HepG-2 cells in 48 h. Fe3O4@indol-IL can mimic the function of c...

In this study, the effects of the size and Chinese traditional processing (including elutriation, water cleaning, acid cleaning, alkali cleaning) on realgar nanoparticles (RN)-induced antitumor activity in human osteosarcoma cell lines (MG-63) and hepatoma carcinoma cell lines (HepG-2) were investigated. The human normal liver cell line (L-02) was used as control. RN was prepared by high-energy...

Eight platinum(II) compounds with a new chiral ligand, 2-(((1R,2R)-2-aminocyclohexylamino)methyl)phenol (HL), were designed, prepared and spectrally characterized. All compounds showed better aqueous solubility than cisplatin and oxaliplatin. In vitro cytotoxicity of these compounds against human HepG-2, MCF-7, A549 and HCT-116 cell lines was evaluated. Results indicated that all compounds show...

OBJECTIVE To investigate the effects of β-Elemene (β-ELE) on the proliferation, apoptosis, and topoisomerase I (TOPO I) and topoisomerase IIα (TOPO IIα) expression and activity of human hepatocarcinoma HepG-2 cells. METHODS After treatment with β-ELE, morphological alterations of HepG-2 cells were observed under an inverted microscope. Cell proliferation was assessed using an MTT assay, cell ...

A new chiral ligand, 2-(((1R,2R)-2-aminocyclohexyl)amino)acetic acid (HL), was designed and synthesized to prepare a series of novel dinuclear platinum(II) complexes with dicarboxylates or sulfate as bridges. The evaluation of these metal complexes in vitro cytotoxicity against human HCT-116, MCF-7 and HepG-2 cell lines were made. All compounds showed antitumor activity to HCT-116 and MCF-7. Pa...

BACKGROUND Cancer represents a serious threat for human health with high social and economic impacts worldwide. Therefore, the development of new anticancer drugs is of most importance. The aim of the present study was to evaluate the antitumor potential of twelve algae from Portugal coast on an in vitro model of human hepatocellular carcinoma (HepG-2 cells). RESULTS Both extracts of Asparago...

Silver nanoparticles were synthesized using Cynodon dactylon leaf extract and this study demonstrates the efficacy of biologically synthesized Silver nanoparticles (AgNPs) as anticancer and antibacterial agent. Anticancer activity of the biologically synthesized silver nanoparticles was studied using HEpG-2 cell line. The AgNPs showed dose-dependent cytotoxicity against HEpG-2 cells. Antimicrob...
