It is shown that a Coulomb suppression of the stellar enhancement factoroccurs in many endothermic reactions at and far from stability. Contrary tocommon assumptions, reaction measurements for astrophysics with minimal impactof stellar enhancement should be preferably performed for those reactionsinstead of their reverses, despite of their negative reaction Q-value. As ademonstration, the cross section of the astrophysically relevant 85Rb(p,n)85Srreaction has been measured by activation between 2.16<=E_{c.m.}<= 3.96 MeV andthe astrophysical reaction rates at p-process temperatures for (p,n) as well as(n,p) are directly inferred from the data. Additionally, our results confirm apreviously derived modification of a global optical proton potential. Thepresented arguments are also relevant for other alpha- and proton-inducedreactions in the p-, rp-, and nu-p-processes.
