That seems a lot harder to me than you seem to think. That would
mean that you need to come up with a toxin that is activated by
the enzymatic activities of one of these enzymes. I think that's
a pretty difficult task. It would be a lot easier (and I think
the much more standard way to go about this task) to create an
immunotoxin to a cell surface feature that only senescent cells
have (or that they have a lot more of). I would guess that there
are a lot of proteins existing in an oxidized or glycosylated
form on senescent cells that could be exploited. Senescent cells
also have more ryanodine receptors.
