The present invention reports the obtaining of carbonyl compounds and derivatives, through syntheses with high yield and purity, providing anti-humoral active principles with selective antiproliferative properties and anti-metastatic activity.

The present invention refers to the development of new polyfunctional push-pull butadienes and their O and C-prenylated, benzoylated and iodide derivatives, with high electronic conjugation in the lateral chain. These compounds exhibit high anti-tumor selectivity, causing cell death by apoptosis, also show anti-metastatic and non-mutagenic properties in the experimental studies performed.

Disclosed is a 5-methylchromone and the preparation method and application thereof, the 5-methylchromone has the following structure:

##STR00001##

wherein R1 and R2 are alkyl groups. The substituted chromone has the biological activity of inhibiting tyrosinase. The preparation method uses 3,5-dihydroxytoluene as a raw material, and synthesis of chromones substituted with different groups at 2-C through acylation, esterification, rearrangement and cyclization reactions, etc. The 5-methylchromone is a completely new compound in condition that R1 is —CH.sub.2CH.sub.2CH.sub.3, and R2 is —CH.sub.2CH.sub.3, or that R1 is —C(CH.sub.3).sub.3, and R2 is H. All the compounds have obvious inhibitory activity against tyrosinase, and can be used to prepare tyrosinase inhibitors or whitening agents.
