We discuss the string corrections to one-loop amplitudes in AdS$_5times$S$^5$, focussing on their expressions in Mellin space. We present the leading $(alpha)^3$ corrections to the family of correlators $langle mathcal{O}_2 mathcal{O}_2 mathcal{O}_p mathcal{O}_p rangle$ at one loop and begin the exploration of the form of correlators with multiple channels. From these correlators we extract some string corrections to one-loop anomalous dimensions of families of operators of low twist.
