Synthesis and antityrosinase activities of alkyl 3,4-dihydroxybenzoates.

In insects, tyrosinase plays important roles in normal developmental processes, such as cuticular tanning, scleration, wound healing, production of opsonins, encapsulation and nodule formation for defense against foreign pathogens. Thus, tyrosinase may be regarded as a potential candidate for novel bioinsecticide development. A family of alkyl 3,4-dihydroxybenzoates (C₆-C₉), new tyrosinsase inhibitors, were synthesized.
