Current Activities

Dr. Doctor has recently prepared some highly active compounds from naturally sulfated polysaccharides by oversulfation, which are effective as anticoagulants and in enhancing the fibrinolytic process. These are being tested using in vitro systems under physiological conditions using purified human blood proteins such as thrombin and plasminogen. The results are evaluated by comparing these with heparin,  which is a highly sulfated naturally occurring polysaccharide,  widely used for treatment of cardiovascular problems.
