The action of a wide range of drugs effective on Ca2+ channels in animal tissues has been measured on Ca2+ channels open during the action potential of the giant-celled green alga,Chara corallina. Of the organic effectors used, only the 1,4-dihydropyridines were found to inhibit reversibly Ca2+ influx, including, unexpectedly, Bay K 8644 and both isomers of 202–791. Methoxyverapamil (D-600), diltiazem, and the diphenylbutylpiperidines, fluspirilene and pimozide were found not to affect the Ca2… CONTINUE READING
