PROCESS FOR OBTAINING NEW ALKALOID DERIVATIVES

摘要

Radio active isotopes, fluorescent substances or substances absorbing X rays may be added to alkaloid derivatives. The alkaloids may be used also as analgesics for the treatment of polyarthritis and as a post-operative anti-inflammatory substance. The new derivatives of the formula where Y : O, S, N; X : N, O; n : 1-3; and (III) represent an isoquinolin-comprising alkaloid, may be prepared by reacting one or a plurality of alkaloids of the formula (III) with alkylation agents.
