Interest in Mannich bases of 8‐hydroxyquinoline stems from reports of their high potency against human cancer cells. In the search for potential anticancer drug candidates, Mannich bases of 8‐hydroxyquinoline (7‐pyrrolidinomethyl‐8‐hydroxyquinoline, 7‐morpholinomethyl‐8‐hydroxyquinoline, 7‐piperidinomethyl‐8‐hydroxyquinoline and 7‐diethylamino‐methyl‐8‐hydroxyquinoline) were synthesised by reaction with various secondary amines and formaldehyde. They were prepared as hydrochlorides.

New heterocycles from 8-hydroxyquinoline via dipolar 1,3-cycloadditions: Synthesis & biological evaluation

Diarylnitrilimine and arylnitriloxide dipoles react with two 8-hydroxyquinoline substrates to give respectively pyrazolinic and isoxazolinic derivatives. The structure of these new heterocycles was

Impact of copper and iron binding properties on the anticancer activity of 8-hydroxyquinoline derived Mannich bases.

Q-4 is identified as a potent and selective anticancer candidate with significant toxicity in drug resistant cells and a linear relationship between the pKa (OH) and IC50 values of the studied 8-hydroxyquinolines was found.

Studies on the structures, cytotoxicity and apoptosis mechanism of 8-hydroxylquinoline rhodium(III) complexes in T-24 cells

The apoptotic mechanism in T- 24 cells treated with 1 was studied by ROS detection, intracellular Ca2+ concentration measurements and caspase-9/3 activity assay, which suggested that complex 1 induced T-24 cell apoptosis by the disruption of mitochondrial-related mechanisms.

Synthesis, Structure Characterization and Antitumor Activity Study of a New Iron(III) Complex of 5-Nitro-8-hydroxylquinoline (HNOQ).

A new iron(III) complex (1) of 5-nitro-8-hydroxylquinoline (HNOQ) was synthesized and structurally characterized in its solid state and solution state by IR, UV-Vis, electrospray ionization (ESI)-MS,
