We use the QCD sum rules to study possible $B_c$-like molecular states. We
consider isoscalar $J^P = 0^+$ and $J^P = 1^+ D^{(\ast)}B^{(\ast)}$ molecular
currents. We consider the contributions of condensates up to dimension eight
and we work at leading order in ${\alpha}_s$ . We obtain for these states
masses around 7 GeV.
