We report CO observations towards MS0735.6+7421 a distant cooling coregalaxy, and towards M87, the nearest cooling core in the center of the Virgocluster. Both galaxies contain radio cavities that are thought to beresponsible for the heating that can regulate or stop the cooling of thesurrounding gas. In this feedback process, there could still be some gascooling along filaments, along the borders of the radio cavities. Molecular gasis known to exist in clusters with cooling cores, in long and thin filamentsthat can be formed behind the rising bubbles inflated by the central AGN. COemission was searched for at several locations along the radio lobes of thosetwo galaxies, but only upper limits were found. These correspond to cold gasmass limits of a few 10^9 Msol for each pointing in MS0735.6+7421, and a few10^6 Msol in M87. This non detection means that either the cooling is stronglyreduced by the AGN feedback or that the gas is cooling in very localized placeslike thin filaments, possibly diluted in the large beam for MS0735.6+7421. ForM87, the AGN heating appears to have stopped the cooling completely.
