In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called In vitro evaluations of biomolecular interactions, antioxidant and anticancer activities of Nickel(II) and Copper(II) complexes with 1:2 coordination of anthracenyl hydrazone ligands, published in 2021-09-01, which mentions a compound: 3326-71-4, Name is 2-Furoic hydrazide, Molecular C5H6N2O2, Product Details of 3326-71-4.

A set of nickel(II) and copper(II) complexes incorporated anthracenyl hydrazone ligands were synthesized and characterized with the help of various spectroscopic techniques. Single-crystal XRD studies revealed that all four complexes have square planar geometry in which the hydrazones are coordinated through NO atoms with 1:2 metal to ligand stoichiometry. Bio-mol. interactions of these complexes were analyzed using UV and emission spectroscopic studies, which revealed that compounds interact with calf thymus DNA (CT-DNA) through intercalation and also bind strongly with BSA. This further has been confirmed by theor. studies. Anticancer nature of the compounds was evaluated with the help of MTT assay against colon cancer cells (HCT-15) and normal skin cells (L929). It is verified that the complexes showed excellent cytotoxicity to cancer cells whereas negligible toxicity towards normal cells. Antioxidant activity was checked by DPPH radical scavenging assay and found that the complexes are capable of reducing available radicals. The complexes initiated cell death via reactive oxygen species generation was determined by ROS assay. The morphol. transformations observed in cell lines treated with different concentrations of complexes have been observed with the help of SEM (SEM). Flow cytometric anal. expressed that the synthesized complexes can induce apoptotic cell death, hence eligible for further studies.
