Superior PDCs “A team of researchers from Lobachevsky University (Nizhny Novgorod, Russia) headed by Professor Alexei Fedorov, chair of the Organic Chemistry Department, is working to create a new generation of targeted anti-cancer drugs for photodynamic therapy.
Today, there are many ways to fight cancer. The problem is that every case of cancer is unique in its own way, and there is no single winning treatment strategy. Doctors can try to combine different therapies and observe the best response to their combination.
On widely used treatment method is photodynamic therapy. "In this method, a photosensitizer is injected into the bloodstream or applied to the affected area of the skin, and used to destroy tumors. When this molecule is activated by light, a number of chain processes are initiated that result in the death of tumor cells," Fedorov notes.
However, there are some problems associated with the application of this approach. Current photosensitizer drugs have a number of serious advantages, but one significant drawback: The selectivity of their accumulation in tumor tissue is very low. In other words, when these drugs are administered to the patient, they are distributed almost evenly between healthy tissues and those affected by tumors. It is quite obvious that this balance should be shifted toward predominant accumulation in tumors. Current efforts of researchers in many countries are focused on achieving this goal”
Theralase solved that problem!!!
