Effects of spirogermanium on the in vitro assembly and disassembly of brain microtubules.


The inhibition of microtubule proteins (MTP) assembly by Spirogermanium (SP, 1.25-100 microM) has been studied. Assembly at 37 degrees C was monitored by turbidity measurements and electron microscopy. For SP in 1:1 protein-drug ratio the inhibition of assembly was 50%. Addition of 12.5 microM SP to microtubules induced spontaneous disassembly. SP had less… (More)
