Charmed nuclei are investigated utilizing 
and 
interactions that have been extrapolated from lattice QCD simulations at unphysical masses of 
–570 MeV to the physical point using chiral effective field theory as guideline. Calculations of the energies of 
single-particle bound states for various charmed nuclei from 
Li to 
Bi are performed using a perturbative many-body approach. This approach allows one to determine the finite nuclei self-energy from which the energies of the different bound states can be obtained. Though the interaction inferred from the lattice results is only moderately attractive, it supports the existence of charmed nuclei. Already the lightest nucleus considered is found to be bound. The spin-orbit splitting of the p- and d-wave states turns out to be small, as in the case of single 
hypernuclei. Additional calculations based on the Faddeev-Yakubovsky equations suggest that also 
systems involving a baryon are likely to be bound, but exclude a bound 
state.
