Paragraph 0054; 0055; 0056, (2017/05/13)
PURPOSE: An ascorbic acid derivative in which niacinamide or niacine is introduced and a method for preparing the same are provided to enhance organic solvent solubility and efficiency. CONSTITUTION: A 3-O-substituted ascorbic acid derivative is denoted by chemical formula 1. A method for preparing the 3-O-substituted ascorbic acid derivative of chemical formula 1 comprises: a step of reacting 5,6-alkylidene ascorbic acid derivative with an acid derivative of chemical formula 2 in an organic solvent; and a step of deprotecting under the presence of carbodiimide of chemical formula 4. The organic solvent is amides, sulfoxides, alcohols, ethers, ketones, halogenated hydrocarbons, or fatty acid organic acid.

A series of new arylpropenamide derivatives containing different aryl groups were synthesized, characterized, and evaluated for their anti-hepatitis B virus (HBV) activities. A new high accuracy QSAR model of arylpropenamide was constructed based on a more completely activities data and calculation parameter. The 2D-QSAR equations, by using DFT and multiple linear regression analysis methods, revealed that higher value of thermal energy (TE) and lower entropy (S?) increase the anti-HBV activities of the arylpropenamide molecules. Predictive 3D-QSAR models were established by SYBYL multifit molecular alignment rule. The optimum models were all statistically significant with cross-validated and conventional coefficients, indicating that they were reliable enough for activity prediction.
