Previously obtained hydrochlorides of 1-[3,4-(R1)2-benzyl]-3,3-(R2)2-6,7-(R3)2-3,4-dihydroisoquinolines (R1 = H, MeO, EtO; R2 = Alk; R3 = MeO, EtO) and their benzo[f]-analogs proved to be water-soluble compounds. This advantage enabled additional biological testing of them for a number of activity types such as antiarrhythmic, hemostatic, anthelmintic, and larvicidal. All isoquinoline hydrochlorides were tested for antiarrhythmic activity (CaCl2 model) with 7 of 13 compounds being active. The maximum antiarrhythmic index was 3.97. The obtained isoquinolines were predominantly coagulants (hemostatics) with respect to blood clotting. The most active compound increased blood coagulation by 46.6%. All compounds with anthelmintic activity exceeded the effect of pyrantel. The larvicidal (insecticidal) effect of the most active compound was comparable with that of diazinon.
