Using the Parkes radio telescope, we have searched for pulsed radio emission from the recently discovered X-ray pulsars AX J1811.5-1926 and PSR J0537-6910 in the supernova remnants G11.2-0.3 and N157B, respectively. We detected no significant pulsed radio emission from these pulsars and have set an upper limit of 0.07 mJy on the 1374 MHz flux from AX J1811.5-1926 and upper limits of 0.18 mJy and 0.06 mJy for the flux from PSR J0537-6910 at 660 MHz and 1374 MHz, respectively. Assuming a power law radio spectral index of 2, these flux limits correspond to luminosity limits at 400 MHz of 20 mJy kpc^2 for AX J1811.5-1926 and 1100 mJy kpc^2 for PSR J0537-6910. Our luminosity limit for AX J1811.5-1926 is lower than the observed luminosities of other young radio pulsars. The upper limit on the luminosity for PSR J0537-6910 in N157B is not significantly constraining due to the large distance to the pulsar. We have also searched for giant radio pulses from both pulsars and have found no convincing candidates.
