What is Quinazolinone synthesis and applications?

Quinazolinone synthesis and applications refer to the chemical preparation of quinazolinone compounds, a class of fused heterocyclic structures, and their use in developing inhibitors of protein kinases with antitumor, antimicrobial, and anti-inflammatory activities.

The field encompasses 26,476 works focused on the chemistry, synthesis, and pharmacological properties of quinazoline compounds, including indirubin derivatives. These studies address protein kinase inhibition, antitumor activity, antimicrobial effects, and anti-inflammatory properties. Key keywords include quinazoline, synthesis, anticancer, and biological evaluation.

Why It Matters

Quinazolinone derivatives serve as inhibitors of key enzymes in cancer pathways. For instance, "AZD9291, an Irreversible EGFR TKI, Overcomes T790M-Mediated Resistance to EGFR Inhibitors in Lung Cancer" (Cross et al., 2014) describes AZD9291, a quinazoline-based irreversible EGFR tyrosine kinase inhibitor that counters T790M resistance in non-small cell lung cancer patients, providing clinical benefit after first-generation EGFR TKIs fail. Similarly, "BIBW2992, an irreversible EGFR/HER2 inhibitor highly effective in preclinical lung cancer models" (Li et al., 2008) demonstrates BIBW2992's efficacy in lung cancer models by targeting EGFR and HER2. These applications extend to Src family kinase inhibition, as in "Discovery of a Novel, Potent, and Src Family-selective Tyrosine Kinase Inhibitor" (Hanke et al., 1996), which shows selective inhibition supporting T cell activation studies. Such compounds impact oncology by addressing drug resistance and signaling in malignancies.

Reading Guide

Where to Start

"Identification of a Novel Inhibitor of Mitogen-activated Protein Kinase Kinase" by Favata et al. (1998), as it introduces U0126, a highly cited quinazoline-related inhibitor of MEK and AP-1 transactivation, providing a foundational example of synthesis and kinase inhibition with 3020 citations.

Key Papers Explained

Favata et al. (1998) first identified U0126 as a MEK inhibitor in "Identification of a Novel Inhibitor of Mitogen-activated Protein Kinase Kinase", setting the stage for kinase mapping by Fabian et al. (2005) in "A small molecule–kinase interaction map for clinical kinase inhibitors", which profiles quinazoline-like compounds across kinases. Hanke et al. (1996) built on this with Src-selective inhibition in "Discovery of a Novel, Potent, and Src Family-selective Tyrosine Kinase Inhibitor". Cross et al. (2014) advanced EGFR applications in "AZD9291, an Irreversible EGFR TKI, Overcomes T790M-Mediated Resistance to EGFR Inhibitors in Lung Cancer", while Li et al. (2008) extended to dual EGFR/HER2 inhibition in "BIBW2992, an irreversible EGFR/HER2 inhibitor highly effective in preclinical lung cancer models".

Frequently Asked Questions

What are quinazolinones?

Quinazolinones are fused heterocyclic compounds studied for their chemistry, synthesis, and pharmacological properties, including indirubin derivatives. They exhibit inhibition of protein kinases, antitumor activity, antimicrobial effects, and anti-inflammatory properties. The field includes 26,476 works with keywords like quinazoline, synthesis, and anticancer.

How do quinazolinones inhibit EGFR in lung cancer?

Quinazolinone-based irreversible TKIs like AZD9291 target the T790M mutation in EGFR, overcoming resistance to first-generation inhibitors in non-small cell lung cancer. Cross et al. (2014) showed AZD9291 provides clinical benefit in advanced EGFR-mutant NSCLC. BIBW2992 similarly inhibits EGFR/HER2 effectively in preclinical lung cancer models (Li et al., 2008).

What role do quinazolinones play in kinase inhibition?

Quinazolinones act as selective inhibitors of tyrosine kinases, such as Src family kinases and MEK. Hanke et al. (1996) identified a Src-selective inhibitor affecting T cell receptor-induced activation via Lck. Fabian et al. (2005) mapped interactions of clinical kinase inhibitors, including quinazoline derivatives, against various kinases.

What are applications of quinazolinone synthesis?

Synthesis enables production of compounds for antitumor, antimicrobial, and anti-inflammatory uses. Favata et al. (1998) identified U0126, a quinazoline-related MEK inhibitor, blocking AP-1 transactivation. These target signaling pathways in immune cells and malignancies.

What is the current state of quinazolinone research?

Research covers 26,476 papers on synthesis and biological evaluation, with high-citation works from 1992-2014 focusing on kinase inhibitors. No recent preprints or news in the last 12 months are available. Studies emphasize protein kinase inhibition and anticancer activity.
