Tyrosinase inhibitory activity of supernatant and semi-purified extracts from squid pen fermented with Burkholderia cepacia TKU025

, 2014
Reports of tyrosinase inhibitors from microorganisms are rare. The tyrosinase inhibitory activity was found from the culture supernatant of Burkholderia cepacia TKU025 with 1 % squid pen as the sole carbon/nitrogen source.

Tyrosinase Inhibitors from Crude Drugs.

Biological and Pharmaceutical Bulletin, 1994
Various crude drugs were examined for their tyrosinase inhibitory activity. Marked activity was observed in Chouji and Yakuchi extracts and the active substances in these extracts were identified as eugenol and yakuchinone A, respectively. Other vanillyl compounds such as ferulic acid, curcumin and yakuchinone B also had higher activities than eugenol ...

Mechanisms underlying the protective effects of San‐Bai decoction against UV radiation on the skin

International Journal of Cosmetic Science, EarlyView.
Combining conventional differential expression analysis with differential network analysis offers a promising strategy to uncover the mechanistic basis of the holistic benefits provided by herbal blends. Our findings demonstrated that San‐Bai decoction modulates multiple pathways—not only those related to skin pigmentation, such as ET‐1 signalling, but

Peptide and peptidomimetic tyrosinase inhibitors

Melanin, which is produced by melanocytes and spread over keratinocytes, is responsible for human skin browning. There are several processes involved in melanogenesis, mostly prompted by enzymatic activities. Tyrosinase (TYR), a copper containing metalloenzyme, is considered the main actor in melanin production, as it catalyzes two crucial steps that ...

Real‐world evidence for the efficacy and tolerability of an isobutylamido‐thiazolyl‐resorcinol (Thiamidol)‐containing skincare regimen on facial hyperpigmentation and overall skin appearance: A multi‐centre study in 11 European countries

International Journal of Cosmetic Science, EarlyView.
A Thiamidol‐containing skincare regimen showed significant improvement in facial hyperpigmentation in a real‐world study across 11 European countries. The treatment led to a significant reduction in mMASI scores, enhanced overall skin condition and demonstrated high tolerability.

PDE4 Inhibition in Dermatologic Disease: Impacts Beyond Inflammation

International Journal of Dermatology, EarlyView.
This graphical abstract demonstrates the comprehensive mechanism of PDE4 inhibition in skin physiology. By increasing intracellular cAMP and activating PKA, PDE4 inhibitors exert pleiotropic effects, including immune modulation, pigmentation regulation, barrier enhancement, sensory neuron modulation, and improved wound healing with reduced fibrosis ...
