Quinazoline and Quinoline Derivatives
Quinazolines and quinolines are nitrogen-containing heterocyclic compounds with aromatic structures that play a key role in the synthesis of drugs with anticancer, antimicrobial, and anti-inflammatory activity. Their derivatives feature structural modifications that optimise bioavailability and selectivity, enabling the development of new active ingredients for various therapeutic applications. These compounds are used in the manufacture of APIs for the treatment of cancer, infections, neurodegenerative diseases, and cardiovascular conditions. Additionally, quinazoline and quinoline derivatives are essential in the research of enzyme inhibitors and the design of innovative bioactive molecules.
At CymitQuimica, we offer high-purity quinazoline and quinoline derivatives for applications in chemical synthesis, pharmaceutical development, and biotechnology.
