surface covalent functionalizationPoly(methyl methacrylate) (PMMA) surface is covalently functionalized with L‐3,4‐dihydroxyphenylalanine (L‐DOPA) to form stable coating that significantly improves the biocompatibility of the PMMA. L‐DOPA‐functionalized PMMA also preserves the phenotypic characteristics ...
Based on the strong adhesive behavior of poly(3,4-dihydroxy--phenylalanine) (or poly(DOPA)) on solid surface, poly(vinylidene fluoride) (PVDF) microporous ... LP Zhu,JZ Yu,YY Xu,... - 《Colloids & Surfaces B Biointerfaces》 被引量: 163发表: 2009年 Plasticized microporous poly(vinylidene...
Polyphenoloxidase (PPO) activity at the inoculated sites was determined after various periods of incubation by replacing the inoculum drops with l-尾-3,4-dihydroxyphenylalanine ( l-Dopa) and measuring the formation of dopaquinone spectrophotometrically ( 位 480 n m). Activity was detected at in...
The 3,4-dihydroxyphenylalanine (DOPA) is believed to be responsible for the water-resistant adhesive characteristics of mussel adhesive proteins. Under the inspiration of DOPA containing adhesive proteins, a dopamine-modified poly(卤,-aspartic acid) derivative (PDAEA) was successfully synthesized by ...
Mussel adhesive proteins including special functional groups, such as dopamine and 3,4-dihydroxy-l-phenylalanine (DOPA), exhibit strong adhesion and have thus been used in numerous applications. As a novel dye adsorbent for wastewater treatment, this study examineed poly(vinyl alcohol) (PVA) nanofi...

Tyrosinase catalyzes the hydroxylation of l-tyrosine to 3,4-dihydroxyphenylalanine (l-DOPA), followed by the oxidation of l-DOPA to dopaquinone. Oxidative polymerization of several dopaquinone derivatives gives rise to melanin (Parvez et al., 2006). Thus substances that inhibit tyrosinase may be ...
such as tyrosinase (TYR), 4,5-dihydroxy-phenylala- nine (DOPA)-dioxygenase (DOD) and glucosyltransferases (GTs) have been identified in higher plants.1,8–10 It has been proposed that TYR converts tyrosine to L-3,4-dihydroxyphenylalanine (L-DOPA), which in turn is converted to betalami...
PURPOSE:To obtain a compound useful as an adhesive or drug by reacting 3,4-dihydroxyphenylalanine derivative with a borate or phosphate then with 9-fluorenylmethoxycarbonyl compound. CONSTITUTION:A 3,4-dihydroxyphenylalanine (DOPA for sh... Y Yasuo,M Yasuo 被引量: 0发表: 1991年 ...
4-Me3SiOC6H4CHO or 3,5-(Me3SiO)2-C6H3CHO to provide a second functional handle. The deprotected alcohols were used in the grafting to ofPEG, which in the latter endcap formed a three-armed species with the deprotected dihydroxy arene ring serving as the center of the two arms ...
