✦ Synopsis
In order to identify polypeptides interacting with organic cations like PAEB the photolabile derivative J-azid0-N-[2diethyl([~H]methyI)ethyl]benzan1ide iodide with a specific radioactivity of 4.3 Ci/mmol was synthesized. Photolysis of this derivative using a Rayonet RPR 100 reactor with a maximum emission at 300 nm obeyed first order kinetics with t i n = 13.5 min. The photochemical properties of this addo-derivative of PAEB indicate that it may be well suited for the identification of binding polypeptides by photoaffinity labeling studies.

Die Photolyse dieses Derivates mittels eines Rayonet RPR 100 Reaktors mit einem Strahlungsmaximum bei 300 nm folgt einer Kinetik 1. Ordnung mit t i n = 13.5 min. Die photochemixhen Eigenschaften dieses Azidoderivates von PAEB ermoglichen es, diese Verbindung zur ldentifizierung von bindenden Polypeptiden durch Photoaffinitiitsmarkierung einzusetzen.
