Harvard and Japanese scientists say they’ve made a “landmark” discovery in cancer drug development. In a new study published Monday, they say they have finally found a way to synthesize in bulk a complex class of promising cancer-fighting molecules derived from sea sponges. Their new strategy has already helped speed up research into these molecules, including a planned clinical trial in humans.
Called halichondrins, the molecules were originally discovered by Japanese researchers in the mid-1980s in sea sponges. It became quickly apparent that they were capable of aggressively fighting tumors in both mice and lab dishes containing human cells, and in a way different from other existing treatments.
