Scientists say a new class of drugs may be effective against viruses that
cause diseases like herpes and AIDS.
Instead of trying to kill the virus, these drugs take a different approach:
They prevent an invading virus from using its human host's cdk, a substance
that drives cell division. Without cdk, the virus can't reproduce itself.
It's possible that cdk-blocking agents could be used to fight certain types
of cancer. Scientists still have to access their safety in people as well as
learn how knocking out cdk can prevent a viral infection.
