A series of 4-alkylcatechols and 1,2-diacetoxy-4-alkylbenzenes (from methyl to butyl) were chemically synthesized for in vitro evaluation as stimulators of nerve growth factor (NGF) synthesis. All compounds were proven to be potent in stimulating NGF synthesis in L-M cells (a

Polyphenol oxidase (PPO) has been extracted from both soluble and particulate fractions of loquat fruit (Eriobotrya japonica Lindl. cv. Algerie). The soluble PPO (20% of total activity) was partially purified 3.3-fold after ammonium sulfate fractionation being in its active state.
Topical application of 4-tertiary butyl catechol (TBC) causes vitiligo in the skin of man and animals, and previous electron microscopic studies showed pheomelanin formation in the affected areas. In the present study, we investigated changes of enzyme activities, eumelanin content
