The effects of various azomethine derivatives on microtubule (MT) assembly in vitro as well as on cell proliferation, cell shape, and the cytoskeleton of some cultured murine cell lines were studied. 3 of them, the alpha-diphenylene-N-(p-[bis-(beta-hydroxyethyl)-amino]-phenyl)-nit rone (DHPN), alpha-diphenylene-N-(p-[N-(hydroxyethyl)-N-(gamma-hydroxypropyl)- amino]-phenyl)-nitrone, and alpha-diphenylene-N-(p-diethylaminophenyl)-nitrone, strongly inhibit the assembly of microtubules (MTs) in vitro (50% inhibition at 4 to 7 mumol/l). The same compounds are also able to disrupt preformed microtubules. Moreover, they were found to inhibit proliferation of leukaemia L 1210, melanoma B16 K, fibroblast L 929, and embryo fibroblast cells down to 1 to 10 mumol/l, completely. Immunofluorescence microscopy revealed that DHPN, used as a representative of the active azomethines, causes a reversible destruction of the microtubule part of the cytoskeleton. Apparently resulting from microtubule disruption, the intermediate filament system collapsed whereas the microfilament system remained unaffected. The results indicate that the antiproliferative action of the azomethines is based, at least partially, on their ability to attack microtubules.
