The present invention relates to visible light sensitive photoremovable protecting groups and their parent compounds X including a xanthene, xanthenium or related cores, represented by formula (Xa):(Xa) wherein the substituents are as defined in the description. The invention also relates to a process for the preparation of compounds of formula (Xa). Said compounds are parent compounds of visible light sensitive photoremovable protecting groups. They can be attached to any desired chemically or biologically active agent either via a covalent bond, or a linker. In the resulting conjugates the active agent is rendered inactive (or less active). Irradiation of such photoactivatable conjugates with visible light leads to the release of the agent with restored biological activity. Therefore, invention further relates to photoactivatable conjugates and pharmaceutical compositions containing them, which are suitable for use e.g. in photoactivated therapy.
