title: 2,2'-Phthaloyl-,2,2'-isophthaloyl-, and 2,2'-terephthaloylbis[1,1,1-trimethylhydrazinium] dihydroxide, bis(inner salts): synthesis, partition coefficients, toxicity and effect on ganglionic transmission.
abstract: 2,2'-Phthaloyl-, 2,2'-isophthaloyl, and 2,2'-terephthaloyl-boff++[1,1,1-trimethylhydrazinium] dihydroxide, bis(inner salts) 7, 8, and 9 and their hydrazide and hydrazinium diiodide precursors were synthesized and tested for toxicity and their ability to block sympathetic ganglionic transmission. Only the 2,2'-phthaloyl and isophthaloylhydrazinium diiodides 4 and 5 produced weak inhibition of nerve transmission (35% at 2.15 X 10(-3) M). The inner salts were appreciably less toxic than the hydrazinium diiodides in brine shrimp testing. The log P (log10, chloroform pH 7 buffer system) values of all compounds were determined and those of the inner salts and hydrazinium diiodides were in the range of -3.03 to -3.60.
