  In this note we explore the possibility of obtaining gauge bosons and
fermionic spectrum as close as possible to the Standard Model content, by
placing D3-branes at a ZN orbifold-like singularity in the presence of
D7-branes. Indeed, we find that this is plausible provided a sufficiently high
N is allowed for and the singular point is also fixed by an orientifold action.
If extra charged matter is not permitted then the singularity should
necessarily be non-supersymmetric. Correct hypercharge assignments require a
dependence on some Abelian gauge D7-groups. In achieving such a construction we
follow a recent observation made in Ref. [hep-th/0105155] about the possibility
that, the three left handed quarks, would present different U(2) transformation
properties.
