One of the Crescent City’s time-honored traditions – a steaming bowl of Yak-a-mein Soup, a.k.a., “Old Sober” — after a night of partying in the French Quarter actually does have a basis in scientific fact. That was the word today from an overview of the chemistry of hangovers, presented as part of the 245th National Meeting & Exposition of the American Chemical Society, the world’s largest scientific society.
A team led by Sean Ekins at Collaborative Drug Discovery in Burlingame, Cal., and Joel Freundlich at the University of Medicine and Dentistry of New Jersey-New Jersey Medical School has trained computers to sift through drug libraries and pick out compounds likely to clobber TB with minimal side effects to humans. They have ‘taught’ the computers to understand which chemical features of a drug are associated with efficacy against TB and which are associated with toxicity to mammalian cells. The process may lead to much less trial and error in finding new therapies. The computers even rediscovered a compound reported 40 years ago to have anti-TB activity but since forgotten.

The findings were published today online in Nature.
