Zongatinib (Zongatinib) mechanism of action, pharmacological effects and scientific principles in tumor treatment

Zongertinib (zongertinib) is a new type of small molecule targeted drug, mainly used for the treatment of HER2-positive tumors, especially cancers related to HER2 exon 20 insertion mutations. Its pharmacological effects are based on highly selective inhibition of HER2 tyrosine kinase, by blocking the HER2 signaling pathway, thereby interfering with the proliferation and survival of tumor cells. HER2 is highly expressed or actively mutated in a variety of solid tumors, and is closely related to rapid tumor growth, drug resistance and invasiveness. Therefore, zongatinib exerts anti-tumor effects by targeting HER2 abnormal signals.

The mechanism of action of Zongertinib mainly includes inhibiting HER2 receptor autophosphorylation and the activation of downstream PI3K/AKT and MAPK signaling pathways. By inhibiting these key pathways, zongertinib prevents tumor cell proliferation while inducing cell cycle arrest and apoptosis. This mechanism enables it to show good therapeutic potential in HER2 mutation-positive solid tumors such as lung cancer, breast cancer and gastric cancer, especially in patients who are resistant to traditional chemotherapy or other HER2 targeted drugs.

Scientifically speaking, the selective inhibitory effect of zongatinib stems from its high affinity to the HER2 ATP binding pocket. This precise binding can inhibit the abnormal activation of HER2 signals to the greatest extent without significantly affecting other receptor tyrosine kinases. Compared with traditional chemotherapy drugs, zongatinib has stronger targeting ability, relatively controllable side effect spectrum, and reduces toxic damage to normal tissues, which is in line with the design concept of "precision attack, low toxicity and side effects" of modern targeted therapy.

In clinical application, zongertinib can not only treat HER2 exon 20 mutation-positive solid tumors as a single agent, but can also be used as part of a combination regimen to improve the overall efficacy. Its pharmacological effects and scientific principles provide a theoretical basis for clinical practice, allowing doctors to formulate the best plan based on HER2 mutation status, tumor type and previous treatment response when selecting individualized treatment plans, thereby improving efficacy and patients' quality of life.
