The application discloses a covalent
kinase inhibitor, a preparation method, a pharmaceutical composition and application, the structure of the covalent
kinase inhibitor is as shown in formula I, II, III, IV or V, and the covalent
kinase inhibitor further comprises a pharmaceutically acceptable salt thereof, the covalent kinase inhibitor can be efficiently covalently combined with a target kinase, and simultaneously triggers the release of NO / NO2 — ; on one hand, the covalent combination can covalently inhibit the target kinase containing a sulfydryl group, and on the other hand, the released NO / NO2 — can further produce sulfydryl
nitroso modification on the target kinase or a
protein interacting with the target kinase, thereby inhibiting self-
phosphorylation, preventing kinase
signal transduction and playing a synergistic effect; the covalent kinase inhibitor can act on various kinases related to malignant tumor proliferation, has good selectivity and a low off-target effect, can significantly inhibit the growth of
tumor cells at a
cell and animal level, and has no obvious adverse reactions. In addition, the preparation method is simple and universal, and is conducive to the expansion of a mother
nucleus structure of various other kinase inhibitors.
