Review: synthesis and anticancer activity of pyrimido[4,5-b]quinolines in the last twenty years
View through CrossRef
AbstractPyrimido[4,5-b]quinoline is a vital structural motif. The synthesis of pyrimido[4,5-b]quinolines has been a challenging topic in medicinal chemistry. A wide range of starting materials have been employed to achieve this nucleus such as quinoline derivatives and isatins. Multi-component one-pot synthestic approaches were employed either by using barbituric or thiobarbituric acid, amines and aldehydes or from 6-aminouracils, aldehydes and cyclohexanone derivatives. Recent synthetic strategies and many green chemistry techniques have improved pyrimido[4,5-b]quinolines synthesis over the last twenty years. Among the many reported biological activities of pyrimido[4,5-b]quinolines, anticancer activity attracted research attention over the past couple of decades. Many derivatives have shown promising anticancer activity on different cancer cell lines such as MCF-7, A549, K562 and others. They also demonstrated activity on different enzymes and receptors such as tyrosine kinases, tyrosyl-DNA Phosphodiesterase II and HDM2 ubiquitin ligase (E3) that promote apoptosis, repair DNA damage, and induce cell cycle arrest. This review critically examines the recent synthetic approaches employed for the synthesis of pyrimido[4,5-b]quinolines and explores their reported anticancer activities.
