摘要
Chemical derivatization of nucleic stains such as ethidium bromide or DAPI with tailored, photoresponsive caging groups, allows for %26quot;on demand%26quot; spatiotemporal control of their in vivo nucleic acid binding, as well as for improving their cellular uptake. This effect was particularly noteworthy for a nitro-veratryloxycarbonyl-caged derivative of ethidium bromide that, in contrast with the parent stain, is effectively internalized into living cells. The activation strategy works in light-accessible, therapeutically relevant settings, such as human retinas, and can even be applied for the release of active compounds in the eyes of living mice.
