Application
3,4-Dihydro-2H-isoquinolin-1-one (CAS 1196-38-9) is a privileged heterocyclic scaffold widely used as a key building block in medicinal chemistry and pharmaceutical research. Its rigid lactam core serves as a central template for the synthesis of diverse bioactive molecules, including potent kinase inhibitors (e.g., Rho-kinase (ROCK) inhibitors for cardiovascular and neurological disorders), PARP inhibitors for cancer therapy, and modulators of neurodegenerative diseases such as Alzheimer's and Parkinson's. The lactam functionality provides a hydrogen bond donor/acceptor site, while the aromatic and aliphatic rings allow further functionalization via cross-coupling, alkylation, or amidation. This intermediate is also employed in the development of anti-inflammatory, antimicrobial, and antiviral agents. Its unique bicyclic structure enhances metabolic stability and target selectivity. High purity ensures reproducible results in high-throughput screening and scalable GMP synthesis.
