Antibodies are described which can bind to a member of a binding pair and to a macromolecule in which the capability of binding to the macromolecule is reversibly inhibited by the presence of a photocleavable moiety. Favoured antibodies are bispecific antibodies, for example against a tumour cell and against an enzyme or a killer cell in which the capability of binding to the enzyme or the killer cell is inhibited until the photocleavable moiety is removed on irradiation.

(EN) Antibodies are described which can bind to a member of a binding pair and to a macromolecule in which the capability of binding to the macromolecule is reversibly inhibited by the presence of a photocleavable moiety. Favoured antibodies are bispecific antibodies, for example against a tumour cell and against an enzyme or a killer cell in which the capability of binding to the enzyme or the killer cell is inhibited until the photocleavable moiety is removed on irradiation.(FR) L'invention concerne des anticorps pouvant se fixer à un élément d'une paire de fixation, ainsi qu'à une macromolécule et dont la capacité de fixation à la macromolécule est inhibée de façon réversible par la présence d'une fraction supprimable par exposition à de l'énergie électromagnétique. Les anticorps préférés sont des anticorps bispécifiques, par exemple, contre une cellule cancéreuse et contre une enzyme ou une cellule tueuse, dont la capacité de fixation à l'enzyme ou à la cellule tueuse est inhibée jusqu'à la suppression de la fraction par exposition à l'irradiation.
Identification of 9-fluoro substituted (−)-cytisine derivatives as ligands with high affinity for nicotinic receptors
(-)-9-Fluorocytisine, (-)-9-methylcytisine and (-)-9-trifluoromethylcytisine were synthesized from the natural product (-)-cytisine. 9-Methyl and 9-trifluoromethyl cytisines display a remarkable affinity at the alpha(4)beta(2) nicotinic receptor subtype (0.2 nM) with a high selectivity versus the alpha(7) nAChR subtype. Comparison of the affinity values suggests that the size of the substituent at the 9 position of (-)-cytisine seems more important than electronic factors for efficient binding and selectivity at alpha(4)beta(2) nAChRs.
