synthesis and tyrosinase inhibitory properties of some novel derivatives of kojic acid
tyrosinase is a multifunctional oxidase that is widely distributed in nature. it is a key enzyme in melanin biosynthesis and is involved in determining the color of mammalian skin and hair. in addition it is responsible for the undesirable enzymatic browning that occurs in plant-derived foods, limiting the shelf -life of fresh-cut products with the resultant economic loss. in recent years ther...
full textIn vitro and in silico studies of the inhibitory effects of some novel kojic acid derivatives on tyrosinase enzyme
Objective(s): Tyrosinase is a key enzyme in pigment synthesis. Overproduction of melanin in parts of the skin results in hyperpigmentation diseases. This enzyme is also responsible for the enzymatic browning in fruits and vegetables. Thus, its inhibitors are of great importance in the medical, cosmetic and agricultural fields. Materials and Methods: A series of twelve kojic acid derivatives wer...
full textsynthesis and characterization of some macrocyclic schiff bases
ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
15 صفحه اولKojic acid-derived tyrosinase inhibitors: synthesis and bioactivity
Tyrosinase is a key enzyme for melanin biosynthesis, catalyzing the oxidation of L-tyrosine to L-dopaquinone. The tyrosinase inhibition is an effective approach to control hyperpigmentation in human skin and enzymatic browning in fruits and vegetables. Kojic acid is a naturally-occurring tyrosinase inhibitor which has been clinically used to treat the hyperpigmentation of skin. However, kojic a...
