Mechanism of Action for Venetoclax: Bcl-2 inhibitors

Bcl-2 inhibitors are a type of medication that target a protein called B-cell lymphoma 2 (Bcl-2). Bcl-2 is a protein that regulates programmed cell death, also known as apoptosis. In normal cells, Bcl-2 helps to prevent excessive cell death. However, in certain diseases, including cancer, Bcl-2 can be overexpressed, leading to uncontrolled cell survival and resistance to chemotherapy.

Bcl-2 inhibitors work by blocking the activity of Bcl-2, promoting apoptosis in cancer cells. By inhibiting Bcl-2, these drugs can help restore the normal balance between cell survival and cell death, leading to the elimination of cancer cells.

These inhibitors have shown promise in the treatment of various types of cancer, including lymphomas, leukemias, and solid tumors. They can be used alone or in combination with other anticancer therapies. Some examples of Bcl-2 inhibitors include venetoclax and navitoclax.

It is important to note that Bcl-2 inhibitors may have side effects, such as gastrointestinal disturbances, fatigue, and increased risk of infections. Therefore, their use should be carefully monitored by healthcare professionals.

Drug Target R&D Trends for Venetoclax

Bcl-2, a protein found in the human body, plays a crucial role in regulating cell survival and apoptosis (programmed cell death). It belongs to the Bcl-2 family of proteins, which are involved in maintaining the balance between cell survival and death. Bcl-2 acts as an anti-apoptotic protein, preventing cells from undergoing programmed cell death and promoting their survival. It does so by inhibiting the release of cytochrome c from mitochondria, which is a key step in initiating apoptosis. Dysregulation of Bcl-2 has been implicated in various diseases, including cancer, where overexpression of Bcl-2 can lead to uncontrolled cell growth and resistance to chemotherapy.

According to Patsnap Synapse, as of 9 Sep 2023, there are a total of 64 Bcl-2 drugs worldwide, from 93 organizations, covering 96 indications, and conducting 827 clinical trials.
