At the time of this publication, over 100 lycopodium alkaloids have been isolated. The 16-carbon-atom-containing lycopodium alkaloid family features a variety of polycyclic ring sizes, stereochemistry, and oxidation patterns. The classic tetracyclic skeleton of the lycopodane family has a rich history in organic chemistry and has been a proving ground for new approaches to the synthesis of poly...

The closure of the coronary arteries was accomplished in my experiments by stopping the mouth of the artery in the sinus of Valsalva, or by plugging the branches with emboli composed of lycopodium spores, or by ]igation of the arteries on the surface of the heart. The first two methods were employed in twenty dogs. In each case the heart was promptly arrested. Closure by ]igation was done in si...
