Nitrogen compounds can be classified as mineral or organic. Mineral compounds are essentially formed by the ammonium ion (NH4+), which is generated when ammonium salts are dissolved in water. Organic compounds, in contrast, are carbon and hydrogen compounds that contain a nitrogen atom. All organic nitrogen-containing compounds can be considered as derivatives of ammonia in which one or more hydrogen atoms are substituted by hydrocarbon radicals.
Genentech, a member of the Roche Group, has announced that its ALK inhibitor Alecensa® (Alectinib) met its primary endpoint of disease-free survival (DFS) at a scheduled interim analysis of the phase 3 ALINA trial. Alecensa as adjuvant therapy resulted in statistically significant DFS and clinically meaningful improvement.
Worldwide, lung cancer is one of the most common cancers, with NSCLC accounting for 80% to 85% of all lung cancer cases. Despite adjuvant chemotherapy, about half of patients with early-stage lung cancer experience cancer recurrence after surgery. Recent therapeutic innovations, including immunotherapy, have improved the outlook for some patients with early-stage NSCLC; however, there are currently no ALK inhibitors approved for early-stage ALK-positive disease. Alecensa is the first ALK inhibitor proven in a Phase 3 trial to reduce the risk of disease recurrence or death in patients with early-stage ALK-positive NSCLC. Chemenu has been working to develop more compounds for drug discovery. Here are the building blocks we can provide.
