d-N-Methyl-isochondrodendrine iodide and d-O-methyl-N-methyl-isochondrodendrine iodide were compared with d-tubocurarine chloride pentahydrate and d-O-methyltubocurarine iodide trihydrate in rats, rabbits, and cats. d-N-Methyl-isochondrodendrine (as the ion) is about 1/20 and d-O-methyl-N-methyl-isochondrodendrine 1/4 as paralysant as d-tubocurarine, which in turn is only 1/10 as active as d-O-methyltubocurarine. Like the tubocurarine compounds, these isochondrodendrine derivatives have relatively little effect in intact animals other than lissive action on skeletal muscles.
