Novel Chemically Modified Curcumin (CMC) Derivatives Inhibit Tyrosinase Activity and Melanin Synthesis in B16F10 Mouse Melanoma Cells

open access: yesBiomolecules, 2021
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 ...

New saccharin derivatives as tyrosinase inhibitors

open access: yesBioorganic & Medicinal Chemistry, 2012
A newly series of 6-(phenylurenyl/thiourenyl) saccharin (6a-y) derivatives were synthesized and their inhibitory effects on the diphenolase activity of banana tyrosinase were evaluated. A 70-fold purification of the enzyme with 6.85% yield was achieved by using a Sepharose 4B-l-tyrosine-p-amino benzoic acid affinity column.

Rhododendrol glycosides as stereospecific tyrosinase inhibitors [PDF]

open access: yesBioorganic & Medicinal Chemistry, 2015
Rhododendrol derivatives 3-12 have been synthesized in six steps, including aldol condensation and/or trichloroacetimidate glycosylation as the key reactions. Each derivative showed effective inhibition of tyrosinase-catalyzed oxidation processes. In particular, a series of synthetic derivatives having an R-stereogenic center at C-2 proved to be more ...

Antamanide Analogs as Potential Inhibitors of Tyrosinase

open access: yesInternational Journal of Molecular Sciences, 2022
The tyrosinase enzyme, which catalyzes the hydroxylation of monophenols and the oxidation of o-diphenols, is typically involved in the synthesis of the dark product melanin starting from the amino acid tyrosine. Contributing to the browning of plant and fruit tissues and to the hyperpigmentation of the skin, leading to melasma or age spots, the ...

The association between neural crest‐derived glia and melanocyte lineages throughout development and disease

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Neural crest cells are a transient cell population that emerges from the dorsal neural tube during neurulation and migrates extensively throughout the embryo. Among their diverse derivatives, glial cells (such as Schwann and satellite ganglionic cells) and melanocytes represent two major lineages. In vitro studies suggested they share a common
