Antisense has been shown to be effective in regulating gene expression and can be used to treat diseases such as cancer and autoimmune disorders.</p>

<p>2',3'-Anhydroinosine is an analog of the purine nucleoside inosine, which has been synthesized by catalytic dehalogenation of 2-fluoro-adenosine.
