Cuminaldehyde is a constituent of the essential oils of eucalyptus, myrrh, cassia, cumin, and others.[1] It has a pleasant smell and contributes to the aroma of these oils. It is used commercially in perfumes and other cosmetics.
It has been shown that cuminaldehyde, as a small molecule, inhibits the fibrillation of alpha-synuclein,[2] which, if aggregated, forms insoluble fibrils in pathological conditions characterized by Lewy bodies, such as Parkinson's disease, dementia with Lewy bodies[3] and multiple system atrophy.[4]
Cuminaldehyde can be prepared synthetically by the reduction of 4-isopropylbenzoyl chloride or by the formylation of cumene.
The thiosemicarbazone of cuminaldehyde has antiviral properties.[medical citation needed]
