Fair enough .
If it was me though , I'd have capitalised on those therapeutic discoveries and made sure that one of them set me up .
It can be too easy to naively think that if you plough the ground that those that come after will reward you with some of what they reap , but in my experience you have to really go after the thing and make certain you get something out of it after . People are pretty selfish in most respects.
Being honest I'd imagine the post doc world is unnecessarily cutthroat . Keep plugging though !!
