Water 47-52 tyrosinase Mus musculus 117-127 23781272-2 2013 Water extracts of Fructus Arctii were shown to inhibit tyrosinase activity in vitro and melanin content in alpha -melanocyte stimulating hormone-stimulated cells to similar levels as the well-known kojic acid and arbutin, respectively. Water 0-5 tyrosinase Mus musculus 55-65 3111852-4 1987 When the enzyme was solubilised from a melanosomal fraction with detergent/water without any buffer, significant linear activity for 2 h was seen at an inhibitory concentration of tyrosine, indicating for the first time the presence of a form of tyrosinase without lag and inhibition by excess tyrosine. Water 75-80 tyrosinase Mus musculus 246-256 16946515-11 2006 Among them, water extract of Galla Chinensis and ethanol extract of Radix Clematidis exhibited higher depigmentation activity and caused lower tyrosinase activity in cell culture assays and are worthy to be further studied. Water 12-17 tyrosinase Mus musculus 143-153 15914904-3 2005 Its distilled water fraction (WEx) was found to stimulate tyrosinase activity in cultured mouse B16 melanoma cells and hair color pigmentation in C3H mice. Water 14-19 tyrosinase Mus musculus 58-68 8395331-5 1993 Direct injection of the tk gene under control of the tyrosinase promoter into established tumors in mice, followed by treatment with ganciclovir, led to significant reductions in resultant tumor size relative to the size of tumor developing in mice treated with water (median tumor weight, 1.65 g versus 2.75 g). Water 262-267 tyrosinase Mus musculus 53-63 3928149-6 1985 Administration of different doses of DFMO in drinking water to B16 melanoma tumor bearing mice also resulted in an increase in tyrosinase activity and a dose dependent inhibition (86-90%) of tumor growth. Water 54-59 tyrosinase Mus musculus 127-137 32390848-2 2020 We found that the water extract of D. morbiferus leaves significantly inhibited tyrosinase activity and melanin formation in alpha-melanocyte stimulating hormone (MSH)-induced B16-F10 cells. Water 18-23 tyrosinase Mus musculus 80-90 27829416-5 2016 METHODS: Three different extracts (water, methanol and ethanol) from leaves, flowers and tubers of A. microcarpus were evaluated for their inhibitory effect on tyrosinase activity using L-3,4-dihydroxyphenylalanine (L-DOPA) as substrate. Water 35-40 tyrosinase Mus musculus 160-170
