“…Also, 2-(1-(coumarin-3-yl)-ethylidene) hydrazinecarbothioamide and 2-(1-(6-chlorocoumarin-3-yl) ethylidene)-hydrazinecarbothioamide demonstrated an irreversible inhibition of tyrosinase 277 . Recently, in the screening of natural products for the development of cosmetic ingredients, two major compounds, trans -N-coumaroyltyramine (IC 50 = 40.6 µM) and cis -N-coumaroyltyramine (IC 50 = 36.4 µM) from Humulus japonicus showed potent tyrosinase inhibition 290 .…”

“…Several stillbenes derivatives from natural and synthetic sources (Figure 8) have been investigated for their tyrosinase inhibition activity including: resveratrol from Morus alba 319 , Pleurotus ferulae 135 , vitis viniferae caulis 320 , Carignan grape juice 321 Artocarpus gomezianus 322 and Streptomyces avermitilis MA4680 323 and also, its derivatives fro m Dipterocarpaceae plants 324 and synthetic sources 325 , oxyresveratrol 326 from Morus australis 327 , Morus alba L (IC 50 = 0.10 ± 0.01 µM) 249 and Cudrania cochinchinensis (IC 50 = 2.33 µM) 255 , azo-resveratrol and its derivatives such as (E)-2-((2,4-dihydroxyphenyl)diazenyl) phenyl 4 methylbenzenesulfonate 328 and azo -oxyresveratrol 329 , trans -resveratrol from Streptomyces avermitilis MA4680 313 , a resveratrol dimer named gnetin C, from melinjo (Gnetum gnemon ) 330 . Also, several hydroxystillbene compounds from synthetic and semisynthetic sources 331 , 332 and from the extract of Veratrum patulum 333 , along with synthetic glycosides of resveratrol, pterostilbene, and pinostilbene 334 , synthetic trans-stilbene derivatives 335 , azastilbene analogs 336 , a newly synthesised stillbene 5-(6-hydroxy-2-naphthyl)-1,2,3-benzenetriol 337 , coumarin-resveratrol hybrids 290 , synthetic polyphenolic deoxybenzoins 218 , hydroxy substituted 2-phenyl-naphthalenes 338 and 4-(6-hydroxy-2-naphthyl)-1,3-bezendiol 339 have been studied for their inhibition activity against tyrosinase. However, based on the enzymatic assays, resveratrol did not inhibit the diphenolase activity of tyrosinase, but L-tyrosine oxidation by tyrosinase was suppressed in presence of 100 µM resveratrol.…”

“…For example, during the screening of natural products for the development of the cosmetic industry, it was found that the aerial extract of Humulus japanicus has tyrosinase inhibitory activity. This plant has been reported to be an antitumor and antioxidant too (Yang et al, 2017). During a screening study, the inhibitory effect of 70 plant species extracts on fungal tyrosinase activity was investigated and several plants with high inhibitory activity were introduced, two of which were Verbascum phoeniceum L. and Astragalus siliqusus Bioss (Hassani and Zarei, 2019).…”
