  We discuss some attempts for the construction of gravity duals of QCD-like
theories. It is analysed some properties of solutions of 10D Type IIB
supergravity theory that attempt to be dual to $\mathcal{N}$=1 gauge theories,
in particular the solutions that belong to Papadoulos-Tseytlin ansatz. We argue
that one could obtain 5D effective theories from 10d solutions and it motivates
the use of phenomenological AdS/QCD models.
