Abstract
Tyrosinases (TYRs; EC 1.14.18.1) catalyze two sequential oxidative reactions of the melanin biosynthesis pathway and play an important role in mammalian pigmentation and enzymatic browning of fruit and vegetables. Inhibition of TYR activity is therefore an attractive target for new drugs and/or food ingredients. In addition, increasing evidence suggests that TYR regulation could be a novel target for treatments of cancer and Parkinson's disease. Biomasses, notably industrial byproducts and biowaste, are good sustainable sources of phytochemicals that may be valorized into bioactive compounds including TYR inhibitors. This review presents potential applications of biomass-derived polyphenols targeting TYR inhibition. Insights into structure-activity relationships of several polyphenols and their glycosides are highlighted. Finally, some remarks and perspectives on research into new TYR inhibitors from biomass waste are provided.

Diverting phenylpropanoid pathway flux from sinapine to produce industrially useful 4-vinyl derivatives of hydroxycinnamic acids in Brassicaceous oilseeds. Metab Eng 2022; 70:196-205. [PMID: 35121114 PMCID: PMC8860379 DOI: 10.1016/j.ymben.2022.01.016] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2021] [Revised: 12/23/2021] [Accepted: 01/29/2022] [Indexed: 11/24/2022]
Abstract
Sinapine (sinapoylcholine) is an antinutritive phenolic compound that can account for up to 2% of seed weight in brassicaceous oilseed crops and reduces the suitability of their protein-rich seed meal for use as animal feed. Sinapine biosynthesis draws on hydroxycinnamic acid precursors produced by the phenylpropanoid pathway. The 4-vinyl derivatives of several hydroxycinnamic acids have industrial applications. For example, 4-vinyl phenol (4-hydroxystyrene) is a building block for a range of synthetic polymers applied in resins, inks, elastomers, and coatings. Here we have expressed a modified bacterial phenolic acid decarboxylase (PAD) in developing seed of Camelina sativa to redirect phenylpropanoid pathway flux from sinapine biosynthesis to the production of 4-vinyl phenols. PAD expression led to a ∼95% reduction in sinapine content in seeds of both glasshouse and field grown C. sativa and to an accumulation of 4-vinyl derivatives of hydroxycinnamic acids, primarily as glycosides. The most prevalent aglycone was 4-vinyl phenol, but 4-vinyl guaiacol, 6-hydroxy-4-vinyl guaiacol and 4-vinylsyringol (Canolol) were also detected. The molar quantity of 4-vinyl phenol glycosides was more than twice that of sinapine in wild type seeds. PAD expression was not associated with an adverse effect on seed yield, harvest index, seed morphology, storage oil content or germination in either glasshouse or field experiments. Our data show that expression of PAD in brassicaceous oilseeds can supress sinapine accumulation, diverting phenylpropanoid pathway flux into 4-vinyl phenol derivatives, thereby also providing a non-petrochemical source of this class of industrial chemicals. A phenolic acid decarboxylase was expressed in developing Camelina sativa seeds. Production of the antinutritive phenolic compound sinapine was reduced by 95%. Hydroxycinnamic acids were converted to 4-vinyl phenols and accumulated as glycosides. The quantity of 4-vinyl phenols was more than twice that of sinapine in wild type. Seed yield appeared not to be affected in either glasshouse or field experiments.

Abstract
Due to the fact that tyrosinase is responsible for biosynthesis and regulation of melanins and browning food products, tyrosinase inhibitors can be favorable agents in cosmetics and medicinal industries. A series of novel 2-hydroxy-4-methoxybenzohydrazide were designed, synthesized, and their new application as tyrosinase inhibitors was also disclosed. Based on in vitro tyrosinase inhibitory assay, 4d as the strongest inhibitor of tyrosinase with an IC50 value of 7.57 μM showed approximately 2.5-fold better inhibition than kojic acid as positive control followed by two compounds 4b (IC50 = 8.19 ± 0.25 μM) and 4j (IC50 = 8.92 ± 0.016) which displayed preferable tyrosinase inhibitory activity. Detailed investigations on the mechanism of action of the 4d reported mix type of inhibition. More importantly, molecular modeling assessments proposed the ability of 4d for potential interaction with Cu (metal)-His (residue) within tyrosinase active site. Overall, 4d is a promising candidate for the development of anti-tyrosinase agents.

Med Chem 2020; 16:892-902. [DOI: 10.2174/1573406415666190724142951] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2019] [Revised: 07/11/2019] [Accepted: 07/12/2019] [Indexed: 02/06/2023]
Abstract
Background:
Melanogenesis is a process of melanin synthesis, which is a primary response
for the pigmentation of human skin. Tyrosinase is a key enzyme, which catalyzes a ratelimiting
step of the melanin formation. Natural products have shown potent inhibitors, but some of
these possess toxicity. Numerous synthetic inhibitors have been developed in recent years may
lead to the potent anti– tyrosinase agents.
Objective:
A number of 4-hydroxy-N'-methylenebenzohydrazide analogues with related structure
to chalcone and tyrosine were constructed with various substituents at the benzyl ring of the molecule
and evaluate as a tyrosinase inhibitor. In addition, computational analysis and metal chelating
potential have been evaluated.
Methods:
Design and synthesized compounds were evaluated for activity against mushroom tyrosinase.
The metal chelating capacity of the potent compound was examined using the mole ratio
method. Molecular docking of the synthesized compounds was carried out into the tyrosine active
site.
Results:
Novel 4-hydroxy-N'-methylenebenzohydrazide derivatives were synthesized. The two
compounds 4c and 4g showed an IC50 near the positive control, led to a drastic inhibition of tyrosinase.
Confirming in vitro results were performed via the molecular docking analysis demonstrating
hydrogen bound interactions of potent compounds with histatidine-Cu+2 residues with in
the active site. Kinetic study of compound 4g showed competitive inhibition towards tyrosinase.
Metal chelating assay indicates the mole fraction of 1:2 stoichiometry of the 4g-Cu2+ complex.
Conclusion:
The findings in the present study demonstrate that 4-Hydroxy-N'-
methylenebenzohydrazide scaffold could be regarded as a bioactive core inhibitor of tyrosinase
and can be used as an inspiration for further studies in this area.

PLANT BIOLOGY (STUTTGART, GERMANY) 2020; 22:1013-1021.

Abstract
Within an Open Science project, research was carried out to describe to the public of the Ghirardi Botanic Garden (BS, Lombardy, Italy) the invisible features of plants. This work is dedicated to Scutellaria altissima L. (Lamiaceae). Micromorphological, histochemical and phytochemical investigations were conducted on the vegetative and reproductive organs to correlate the structures involved in the emission of substances and their unique productivity. This work reports volatile organic compound (VOC) profiles of leaves and flowers and the composition of essential oil (EO) obtained from aerial parts of plants cultivated in Italy that have never been described before. Three morphotypes of glandular trichomes were observed: peltate, short-stalked capitate and long-stalked capitate. Peltate trichomes were the main producers of terpenes, short-stalked capitates of polysaccharides and long-stalked capitates of terpenes and polyphenols. The leaf VOC profile showed heterogeneous composition, with non-terpene derivatives as the major chemical class (71.04%), while monoterpene hydrocarbons represented almost the totality of the flower (99.73%). The leaf presented a higher number of total (37 versus 11) and exclusive (33 versus 7) compounds. (Z)-3-Hexenol acetate was most abundant in the leaf and (E)-β-ocimene in the flower. Four common compounds were detected: β-pinene, β-caryophyllene, γ-muurolene and germacrene-D. The EO contaied 21 compounds, dominated by β-caryophyllene, linalool and hexahydrofarnesyl acetone. This research allowed us to correlate morphotypes of the secretory structures with the production of secondary metabolites, with the aim of providing the public of the Ghirardi Botanic Garden with a dedicated iconographic approach, which accounts for olfactory perception linked to S. altissima.

Abstract
Microorganisms and plants can be important sources of many compounds with potential pharmaceutical applications. Extraction of these matrices is one of the ways of identifying the presence of inhibitory active substances against enzymes whose high activity leads to serious human diseases including cancer, Parkinson's or Crohn's diseases. The isolation and purification of inhibitors are time-consuming and expensive steps in the analysis of the crude extract and therefore, it is necessary to find a fast, efficient, and inexpensive method for screening extracts of interest. TLC-Bioautography combines the separation of the extract on a thin layer with its subsequent biological analysis. TLC-Bioautography methods have been developed for several classes of enzymes including oxidoreductases, hydrolases and isomerases, and there is a potential for developing functional methods for other classes of enzymes. This review summarizes known TLC-Bioautography methods and their applications for determining the presence of enzyme inhibitors in extracts and compares the effectiveness of different methodological approaches. It also indicates the current state and perspective of the development of TLC-Bioautography and its possible future applications.
