H.K. Wasner finished studying chemistry with a masters degree; thereafter, he obtained a PhD in biochemistry in the lab of Feodor Lynen, and became a postdoc in the lab of Earl Sutherland, where he started the search for an antagonist of cyclic AMP, now called cyclic PIP. This is a task he continues up to today. Presently, his goal is to succeed with the chemical synthesis of cyclic PIP.
