One boson exchange approach is used to study bound state problems for the ΛcN and ΛcΛc systems. The coupling constants are determined by various methods while the phenomenological cutoffs at vertices are parameterized with a free cutoff parameter. The numerical results are sensitive to the cutoff parameter. Although we cannot determine it at present, it is possible to have molecular bound states ΛcN and ΛcΛc for a reasonable value.
