HIV's Crystal Key
Eddy Arnold, Center for Advanced Biotechnology and Medicine and Rutgers University Department of Chemistry and Chemical Biology, was recently featured in the Star-Ledger, December 12, 2004 for his crusading research in the pursuit of revolutionary AIDS drugs (DAPY compounds) which may be more effective treatments for HIV, the deadly virus that causes AIDS. Through Arnold's crystallography research and dedication to the concept that reverse transcriptase (RT) was a key target of HIV, the future now looks promising with one of the DAPY compounds (TMC-125) entering Phase III clinical trials in the near future. Arnold's group, which has used CHESS extensively to study RT, continues its efforts to detail the structure and function of RT, and to develop new classes of inhibitors that may be able to more effectively evade HIV drug resistance. They are also pursuing the development of an AIDS vaccine by generating combinatorial libraries of chimeric human rhinoviruses displaying key HIV neutralizing epitopes, including segments of the HIV-1 gp41, part of the highly conserved viral fusion machinery.

A research team has produced the fastest movies ever made of electron motion. Created by scattering x rays off of water, the movies show electrons sloshing in water molecules, and each frame lasts just 4 attoseconds (quintillionths of a second). The results, published in the 11 June PRL, could let researchers "watch" chemical reactions even faster than those viewable with today's "ultrafast" pulsed lasers.
