tioguanine and mercaptopurine comparison - purine analogs and leukemia treatment

The difference is that tioguanine replaces a hydrogen with an amine group. What would be the effect of replacing the hydrogen on the smaller ring of mercaptopurine with an amine group? Or a methyl group?

Answering those questions could lead to a new leukemia medicine. 




Rotating molecules so that the main features point in the same direction can offer insights. It's easier to do that with ball and stick models. 



I wonder about the effects of replacing the double-bonded oxygens with sulfur in the above molecules.
