chemical genetics (ATP-gamma-S)

I’m curious if anyone has any information about ATP-gamma-S derivatives and worms. I know Kim et al. 2008 used a PP1 analog to inhibit asSAD-1 in a liquid culture.
-would the same strategy work with ATP-gamma-S derivatives?
-if not, would it be possible to inject (N6-(benzyl)ATP-γ-S, for example) into the gonad and have it incorporated into the embryos?
thanks,
