In this work, a new relativistic energy density functional based on the density-dependent point coupling interaction is introduced. The parameters of the effective DD-PCX interaction are optimized for the first time using the isoscalar giant monopole resonance energy and dipole polarizability in 208Pb as well as the ground-state properties of selected atomic nuclei. In this way, the isovector properties of the energy density functional, as well as the symmetry energy close to the saturation density are constrained in a unique way using the observables on nuclear excitations in the optimization procedure. It is shown that the new effective DD-PCX interaction is quite successful in the predictions of the nuclear ground-state properties and neutron skin thickness of nuclei as well as the properties of collective excited states in nuclei.
