Mechanism of Action for Disitamab Vedotin: HER2 antagonists & Tubulin inhibitors

HER2 antagonists are a type of medication that specifically target and block the activity of the HER2 protein. HER2, also known as human epidermal growth factor receptor 2, is a protein that plays a role in cell growth and division. In some cases, HER2 can be overexpressed in certain types of cancer cells, such as breast cancer cells, leading to uncontrolled cell growth and tumor formation.

HER2 antagonists work by binding to the HER2 protein and preventing it from sending signals that promote cell growth and division. By inhibiting the activity of HER2, these medications can help slow down or stop the growth of cancer cells that rely on HER2 signaling for their survival.

Tubulin inhibitors, on the other hand, are a class of drugs that interfere with the function of tubulin, a protein involved in cell division. Tubulin is responsible for forming the structural framework, called microtubules, that help separate chromosomes during cell division.

Tubulin inhibitors can disrupt the formation of microtubules, preventing proper chromosome separation and ultimately leading to cell death. These drugs are commonly used in cancer treatment because rapidly dividing cancer cells are particularly sensitive to the disruption of cell division.

In summary, HER2 antagonists specifically target the HER2 protein to inhibit its activity and slow down cancer cell growth, while tubulin inhibitors interfere with the function of tubulin to disrupt cell division and induce cell death. Both types of medications are important in the field of biomedicine for the treatment of certain types of cancer.
