Descrição geral

4-Ethylbenzaldehyde is a by-product of disinfection. Kinetic constants (KI) of 4-ethylbenzaldehyde for inhibition of the diphenolase activity of mushroom tyrosinase has been investigated.

Aplicação

4-Ethylbenzaldehyde has been used in the synthesis of 4,4′-diaminotriphenylmethanes under microwave irradiation, which is useful for parallel library syntheses.

A kinetic study of the inhibition of mushroom tyrosinase by 4-substituted benzaldehydes showed that these compounds behave as classical competitive inhibitors, inhibiting the oxidation of L-3,4-dihydroxyphenylalanine (L-DOPA) by mushroom tyrosinase (o-diphenolase activity). The kinetic parameter (K(I)) characterizing this inhibition was
