Patent number: 5468854Abstract: Conjugates of fluorescent labels with specific, selective, and high affinity ligands for receptors have been synthesized and used to directly measure binding to receptors. In the examples, fluorescein conjugates of the high-affinity benzodiazepine receptor ligands Ro 15-1788 and Ro 7-1986 were synthesized. The binding of these fluorescent ligands (BD 621, BD 623 and BD 607) to benzodiazepine receptors was characterized by direct fluorescence measurement. Both the equilibrium dissociation constants (K.sub.D) of BD 621 and BD 607 and the maximum number of binding sites (B.sub.max) estimated by fluorescence monitoring were consistent with values obtained by using radioligand binding techniques. The binding of BD 621 and BD 607 assessed by fluorescence measurement was reversible, abolished by photoaffinity labeling with Ro 15-4513, and unaffected by a variety of substances that do not bind to benzodiazepine receptors.Type: GrantFiled: July 22, 1993Date of Patent: November 21, 1995Assignee: Pharmaceutical Discovery CorporationInventors: R.

Patent number: 5013836Abstract: The difficulty of methylating a hindered piperidinyl, piperazinyl, or diazepinyl group with an Eschweiler-Clarke ("E-C") procedure without using a large molar excess (more than double) of formaldehyde is surprisingly found to be non-existent in the case of a diazacycloalkan-2-one group with a hindered N.sup.4 - or N.sup.5 -atom of its NH group which is to be methylated. The N.sup.4 - or N.sup.5 -atom of a polysubstituted diazacycloalkan-2-one group ("DCA") is substantially stoichiometrically converted even when a conventional E-C procedure is starved of HCHO, that is, with a much smaller molar excess of formaldehyde than deemed necessary. The effective molar ratio of NH groups: HCHO in the starved E-C process is in the range from 1:1 to 1:1.5, in the presence of enough formic acid to function both as reactant and solvent not only for a DCA-containing complex amine ("starting amine") to be methylated, but also for the methylated amine (product).Type: GrantFiled: November 21, 1989Date of Patent: May 7, 1991Assignee: The B.
