2-Butenolide (7.6 ml, 0.1mol) and piperidine (2.5 ml, 0.025 mol) were dissolved in ethanol (50 ml), and then under stirring asolution of 5-(4-methyl-phenyl)furfural (9.3 g, 0.05 mol) in 50 ml of ethanol was added to this mixture.The reaction mixture was left to stand at the ...
A typical example was mangiferin (4) and its ether 7-O-methylmangiferin (14). As shown in Table 1, the IC50 values at two pH values (pH 4.5 and 7.4) decrease significantly from mangiferin (4) to 7-O-methylmangiferin (14). This is because methylation breaks the 6,7-di-OHs ...
