AB RNA and ribonuclease-resistant RNA analogs that bound and neutralized
Rous sarcoma virus (RSV) were isolated from a large pool of random
sequences by multiple cycles of in vitro selection using infectious
viral particles. The selected RNA pool of RSV-binding sequences at a
concentration of 0.16 microM completely neutralized the virus. Of 19
sequences cloned from the selected pool, 5 inhibited RSV infection. The
selected RNA and RNA analogs were shown to neutralize RSV by interacting
with the virus, rather than by adversely affecting the host cells. The
selection of the anti-RSV RNA and RNA analogs by intact virions
immediately suggests the potential application of this approach to
develop RNA and RNA analogs as inhibitors of other viruses such as human
immunodeficiency virus.
