Design, synthesis and biological evaluation of novel kojic acid triazole hybrids as tyrosinase inhibitors and antibrowning agents

open access: yesScientific Reports
In this study, two series of kojic acid triazole hybrids, namely 6a–6p and 13a–13t, were designed and synthesized. Subsequently, their biological activities including anti-tyrosinase, antioxidant, and as anti-browning effects were investigated.

Peptide and peptidomimetic tyrosinase inhibitors

open access: yes
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 ...

Dialkylphosphorylhydrazones as potent tyrosinase inhibitors

open access: yesJournal of the Brazilian Chemical Society, 2012
Nineteen dialkylphosphorylhydrazones with different substituents at the aromatic ring were evaluated as potential tyrosinase inhibitors, which could then be used as efficient agents in the control of pigmentation disorders. The inhibition activity was measured by a modified Patil and Zucker UV-Vis method.

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

open access: yesInternational 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

Obstruction of Water Uptake in cut Chrysanthemum Stems after Dry Storage: Role of Wound-induced Increase in Enzyme Activities and Air Emboli [PDF]

open access: yes, 2009
Hydraulic conductance of cut chrysanthemum stems was lowered by the aspiration of air as well as by a wound-induced plant response. By measuring the hydraulic conductance of stem segments in which air could be introduced into and/or removed from the ...

DOCKING OF TYROSINASE CICLOARTANE INHIBITORS

open access: yesVitae, 2009
Berenjenol (21:24-epoxy-24-methyl-cicloartane) isolated from leaves of Oxandra cf. xylopioides (Annonaceae), and its synthetic derivatives Berenjenol-3-acetate and 3-Oxoberenjenol are tyrosinase inhibitors (EC 1.14.18.1). These compounds are triterpenoids type cycloartanes, whose structure-activity relationship has been studied on similar compounds ...
