1,2-di(9,10-dibromostearoyl)phosphatidylcholine

1,2-di(9,10-dibromostearoyl)phosphatidylcholine (DBPC) is a synthetic phospholipid analogue that is structurally similar to natural phosphatidylcholine (PC), but with two bromine atoms attached to each stearic acid chain at the 9 and 10 positions.

**Here's why it's important for research:**

* **Membrane Perturbation:** DBPC disrupts the structure and function of cell membranes. The bromine atoms create a kink in the fatty acid chain, which disrupts the packing of lipids in the membrane, causing changes in fluidity, permeability, and membrane protein function. This makes DBPC a useful tool for studying membrane dynamics and the effects of membrane disruption on cellular processes.
* **Cell Signaling:** DBPC can activate specific signaling pathways, particularly those involving phosphatidylinositol 3-kinase (PI3K) and protein kinase C (PKC). This makes DBPC useful for investigating the role of these signaling pathways in various cellular processes like cell proliferation, survival, and apoptosis.
* **Cancer Research:** DBPC has shown some anti-cancer activity in laboratory settings. It can induce apoptosis in cancer cells and inhibit their growth. The mechanism behind this effect is related to its ability to disrupt membrane integrity and activate signaling pathways involved in cell death.
* **Drug Delivery:** DBPC has been explored as a potential carrier for delivering drugs across cell membranes. Its unique properties, including its ability to disrupt membranes and interact with signaling pathways, make it a potential candidate for targeted drug delivery systems.

**Important Notes:**

* DBPC is a synthetic compound and not naturally occurring in living organisms.
* It's important to note that the research on DBPC is still ongoing, and more studies are needed to fully understand its mechanisms of action and potential applications.
* As a synthetic compound, DBPC may have potential toxicity and should be used with caution in research.

Overall, 1,2-di(9,10-dibromostearoyl)phosphatidylcholine is a valuable research tool for understanding membrane dynamics, cell signaling, and potential therapeutic applications.
