摘要:
Practolol halogenated derivatives, useful as myocardial β adrenergic receptor markers, are of formula (I): in which R1 can be various groups, for example, an isopropyl group, R2 is a group of formula CH=CHX, C CX, O-(CH¿2?)pX or OCH2CH=CHX, with X being an optionally radioactive halogen atom, R?7¿ is O or NHCO and n is equal to 0, 1 or 2. When X is 123¿I?, the derivatives of the invention can be used as markers for assaying myocardial β adrenergic receptors.
