nucleoside analogues: pH/conc.to dissolve??

I am using AZT, ddI, and ddG in an attempt to inhibit a RT-like
enzyme. I purchased these reagents in powdered form from 3 different
companies, all of whom did not supply a data sheet nor could they really
help me over the phone. Most papers I've read say that they dissolved
them in water or DMSO. For my experiments, I need them in water or cell
media at fairly high concentrations (500micromolar), but I the first time
I prepared them in water (at 10mM stocks), they were difficult to
dissolve (thus i had to heat them) and became inactive.
Does anyone have experience getting these guys into an aqueous solution
(pH, concentration, etc) so that they remain active? Is temperature an
issue (ie. can i heat them slightly to dissolve?)
Any advice would be appreciated. Please respond to my listed e-mail address.
