Nilotinib (CAS 641571-10-0) is a high-potency anticancer API, belonging to the second-generation BCR-ABL tyrosine kinase inhibitor (TKI) class. Its unique molecular structure binds specifically to the ATP-binding site of BCR-ABL fusion protein, exerting stronger inhibitory activity than first-generation TKIs and overcoming most imatinib-resistant mutations. Produced via advanced precision synthesis, it maintains ultra-high purity and consistent bioactivity, fully complying with international pharmaceutical quality standards.
