(also cinnamic aldehyde, Î²-phenylacrolein), C 6 H 5 CH=CHCHO, a fatty-aromatic unsaturated aldehyde; a colorless liquid with the characteristic odor of cinnamon. It has a boiling point of 252Â°C and a density of 1.110 g/cm 3 (at 20Â°C). It is poorly soluble in water and very soluble in alcohol and ether. Cinnamaldehyde is a component of many essential oils (cinnamon oil and others).
Cinnamaldehyde is a natural product from spices that inhibits cell separation in Bacillus cereus. Cell division is regulated by FtsZ, a prokaryotic homolog of tubulin. FtsZ assembles into the Z-ring at the site of cell division. Here, we report the effect of cinnamaldehyde on FtsZ and hence on the cell division apparatus. Cinnamaldehyde decreases the in vitro assembly reaction and bundling of FtsZ.
