Abstract/OtherAbstract:
The efficient synthesis, physicochemical and photolytical properties of a photoactivable BAPTA-based Ca2+ cage containing two photosensitive o-nitrobenzhydryl groups attached to the aromatic core are described. Ca2+ release in living cells was evaluated. The doubly substitution with the chromophores caused a significant improvement of the Ca2+ release properties of nitr-T against singly substituted reported nitr-x derivatives without compromising Ca2+/Mg2+ selectivity or pH insensitivity. Our results demonstrate a general strategy to improve light-triggered Ca2+ release which may open a door to prepare more efficient, selective and pH-insensitive photolabile Ca2+ chelators.
