Patent number: 4806604Abstract: The present invention discloses a new class of calcium chelating compounds which have a decreased affinity for calcium following illumination. These new compounds contain a photolabile nitrobenzyl derivative coupled to a tetracarboxylate Ca.sup.2+ chelating parent compound having the octacoordinate chelating groups characteristic of EGTA or BAPTA. However unlike EGTA or BAPTA-like compounds, in which the two halves of the chelator are linked by a simple 1,2-ethanediyl moiety, the compounds of the present invention modify the stereochemical conformation of this linkage by adding bulky substituents or incorporating the linkage into a carbocyclic or heterocyclic ring. In a first form, the new compounds are comprised of a BAPTA-like chelator coupled to a single 2-nitrobenzyl derivative, which in turn is a photochemical precursor of a 2-nitrosobenzophenone.Type: GrantFiled: May 13, 1987Date of Patent: February 21, 1989Assignee: Regents of the University of CaliforniaInventors: Roger Yonchien Tsien, Stephen R.
