Richard G Powell, Cecil R Smith Jr: Chemotherapeutically active maytansinoids from Trewia nudiflora. The United States of America represented by the Secretary of Agriculture, M Howard Silverstein, David G McConnell, Curtis P Ribando, February 2, 1982: US04313946 (120 worldwide citation)

A novel group of maytansinoid compounds has been discovered in the seed tissue of Trewia nudiflora. They are represented by the general formula ##STR1## and are all characterized by a distinguishing methoxy group on the C-15 carbon. These isolates have proven to be effective in causing the remission ...
