The Sea is a still unexplored source of chemicals. In the last few years, scientists have studied these chemical substances in the hope that some of them might be a solution of today incurable illness as cancer and AIDS.

Dr. Kenneth Rinehart, professor of chemistry at the University of Illinois, is one of the pioneers in the adventure of chemical research with medical purposes in the sea. Kenneth has already dedicated 20 years of his life to the Et 743 and now he is likely to see it elaborated into a new medicine against cancer.
