Abstract: If G is a locally compact group, then $ \mathrm{UBC}_r (G)^*$, the dual of the space of bounded right uniformly continuous complex-valued functions on G, with the Arens product is a Banach algebra. We prove in this paper a result that will have as a consequence the following: Let $ {G_1},{G_2}$ be locally compact groups. Then the Banach algebras $ \mathrm{UBC}_r{({G_1})^ \ast }$ and $ \mathrm{UBC}_r{({G_2})^\ast}$ are isometric isomorphic if and only if $ {G_1}$ and $ {G_2}$ are topologically isomorphic.
