Abstract
Description: Two new ruthenium(II) complexes containing guanidinium as ligands, [Ru(dip)2 (L1)]3+ (Ru1) and [Ru(dip)2(L2)]3+ (Ru2) (dip=4,7-diphenyl-1,10-phenanthroline; L1=1-(4-(1H-imidazo[4,5- f][1,10]phenanthrolin-2-yl)phenyl)guanidine cation; L2 = 1-(3-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl) phenyl)guanidine cation) have been synthesized and characterized. Both complexes display higher cytotoxicity against several cancer cell lines compared to cisplatin and are less cytotoxic on the nontumorigenic cell line LO2. Intracellular distribution studies show that these complexes are selectively localized in the cytoplasm.
Findings: Further analysis revealed that Ru1 and Ru2 had no obvious effects on the cell cycle and induced apoptosis in HeLa cells via the mitochondrial pathway, which involved reactive oxygen species (ROS) accumulation, mitochondrial dysfunction, and Bcl-2 family member activation. Taken together, the two complexes have the potential to be utilized as anticancer agents.
Keywords: Synthesis, Ru(II) complexes, cytotoxicity, apoptosis, protein, tumor cell.

Induction of cell death in cancer cells by modulating telomerase activity using small molecule drugs
Telomeres are distinctive but short stretches present at the corners of chromosomes and aid in stabilizing chromosomal makeup. Resynthesis of telomeres supported by the activity of reverse transcriptase ribonucleoprotein complex telomerase. There is no any telomerase activity in human somatic cells, but the stem cells and germ cells undergone telomerase ...read more
