A series of 3,5-substituted-4,5-dihydro-1H-pyrazole-1-carbothioamide derivatives were synthesized. Their structures were determined on the basis of spectroscopic data interpretation and their tyrosinase inhibitory activity was determined. The results showed that compound 2 (at 1.00 mg/mL) exhibits significant tyrosinase inhibitory activity with % inhibition of 91.866 ± 2.086 with L-tyrosine as substrate whereas compound 3 (at 1.00 mg/mL) exhibits significant tyrosinase inhibitory activity with % inhibition of 79.266 ± 0.552 and 89.593 ± 1.015 with L-tyrosine and L-DOPA as substrates.

Abstract:
AbstractAnisic acid (p-methoxybenzoic acid) was characterized as a tyrosinase inhibitor from aniseed, a common food spice. It inhibited the oxidation of l-3,4-dihydroxyphenylalanine (ʟ- DOPA) catalyzed by tyrosinase with an IC50 of 0.60 mᴍ. The inhibition of tyrosinase by anisic acid is a reversible reaction with residual enzyme activity. This phenolic acid was found to be a classical noncompetitive inhibitor and the inhibition constant KI was obtained as 0.603 mᴍ. Anisic acid also inhibited the hydroxylation of ʟ-tyrosine catalyzed by tyrosinase. The lag phase caused by the monophenolase acti

In silico results using mushroom tyrosinase and human tyrosinase showed that the 2,4-hydroxyl substituents on the phenyl ring of 1b played an important role in the inhibition of both tyrosinases.

Skin hyperpigmentation disorders arise due to excessive production of the macromolecular pigment melanin catalyzed by the enzyme tyrosinase. Recently, the therapeutic use of curcumin for inhibiting tyrosinase activity and production of melanin have been recognized, but poor stability and solubility have limited its use, which has inspired synthesis of curcumin analogs. Here, we investigated four novel chemically modified curcumin (CMC) derivatives (CMC2.14, CMC2.5, CMC2.23 and CMC2.24) and compared them to the parent compound curcumin (PC) for inhibition of in vitro tyrosinase activity using t

Abstract:
Abstract: The long-term goals of our research are to understand the regulation of sclerotial development and pathogenicity in S. sclerotior11111. The focus in this project was on the elucidation of the signaling events and environmental cues involved in the regulation of these processes, utilizing and continuously developing tools our research groups have established and/or adapted for analysis of S. sclerotiorum, Our stated objectives: To take advantage of the recent conceptual (ROS/PPs signaling) and technical (amenability of S. sclerotiorumto manipulations coupled with chemical genomics and
