Using Fourier transform infrared spectroscopy, the researchers matched the poison’s active ingredient to ouabain, a crystalline glycoside that inhibits the sodium-potassium pumps found in the cell membranes of mammals. The scientists hope that an understanding of L. imhausi’s own immunity to ouabain might translate to future medical therapies. /articles/89/i38/Elemental-Manhattan-Giant-Rats-Take.html 20110919 89 38 /magazine/89/08938.html Elemental Manhattan, Giant Rats Take East Africa Elemental Manhattan, IYC, African crested rat, ouabain Newscripts Lauren K.

He is currently working toward the total synthesis of the cardenolide ouabain. He received a B.S. degree in chemistry from the University of Miami and performed undergraduate research under the supervision of Jeff D. Evanseck and Angel E. Kaifer. His fellowship is sponsored by DuPont Pharmaceutical.
