It's ongoing work for me. Lately I've been digging through a lot of gene expression datasets to try and figure out which genes are the most overexpressed in aging tissues. I then use bioinformatics tools like clue.io to figure out which OTHER genes regulate them, and also possible drugs.
There are a number of pathways that seem to be downregulated by purigenic receptors, many of which are sensitive to adenosine. Caffeine blocks adenosine receptors and blocks signaling.
What could be happening here is suppressing inflammation, since evidently purine nucleotides activate some immune cells.

The key is to make sure everything works out quantitatively: https://www.ncbi.nlm.nih.gov/pubmed/12242150 https://www.ncbi.nlm.nih.gov/pubmed/12242150
