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.

Twelve novel hybrids of slowly releasing hydrogen sulfide donor ADT-OH combined with nicotinic acid were synthesized. All of their structures had been confirmed by1H NMR,13C NMR and MS spectra. The target compounds were evaluated for their neuroprotective effects on hippocampal neuron HT22 cells against glutamate-induced injury at the concentrations of 1–100?μM with MTT assay, and their toxicity on HT22 cells untreated by glutamine at the concentration of 100?μM. The active compound was further investigated for its effect on ischemic infarct volume by intraperitoneal injection at 3?h after ischemia in mice models of permanent middle cerebral artery occlusion (pMCAO). The results showed that all the compounds significantly protected HT22 cells from glutamate-induced damage at most of the experimental concentrations, and had no or little neurotoxicity on normal HT22 cells at the high concentration. More importantly, compound A6 significantly reduced infarct volume in the pMCAO model. These results suggested that compound A6 may be promising for further evaluation for the intervention of cerebral ischemic injury.
