Journal of Radioanalytical and Nuclear Chemistry | 1986

A new intermediate for the rapid synthesis of N-isopropyl-p-/125I/- or p-/123I/ amphetamine

Jiří Protiva; Václav Křeček; Ladislav Lešetický

The triazene derivative of N-isopropylamphetamine XI, has been prepared in seven steps from amphetamine, as a new intermediate which is readily converted to N-isopropyl-p-iodoamphetamine /XII/. XI makes now possible the simple, rapid and regiospecific synthesis of /125I/- or /123I/-XII direct before the application.


Journal of Radioanalytical and Nuclear Chemistry | 1988

New types of125I-radioligands for RIA of steroid compounds

K. Vulterin; Z. Jurka; K. Vereš; Jiří Protiva

We prepared new125I-radioligands of the arylhydrazone type for the RIA of steroid compounds and studied the effect of the chain length between125I and the antigen on the antibody⇌antigen reaction.
