cordycepin triphosphate vs adenosine triphosphate & potential cancer link

Zombie Caterpillar Fungus Could Be Used to Save Human Lives

Cordycepin triphosphate has shown promise as anti-tumor drug for cancer treatment. It is made in nature by a parasitic fungus. In host caterpillars, CTP may disable an immune response against fungi.  

The two differ by one oxygen atom. For easier comparison, the un-phosphorylated molecules are below.  

I have been compiling a dictionary of organic compounds grouped according to their empirical formulas.

The above molecules have some similarity to extraterrestrial amino acids and precursors from the Murchison meteorite.
