We discuss several properties of two families of finite-range interactions in infinite nuclear matter, aiming in particular to their isovector properties. We find that the recent parameterisations of both Gogny and Nakada provide a reasonable description of the properties of the infinite medium as well as an equation of state capable of sustaining a two solar mass neutron star. We also discuss the pairing properties in the spin-singlet channel for both families of interactions.
