Acipimox (CAS NO.51037-30-0) is a niacin derivative used as a hypolipidemic agent. It is used in low doses and may have less marked adverse effects,although it is unclear whether the recommended dose is as effective as are standard doses of nicotinic acid . These drug inhibit hepatic triglyceride production and VLDL secretions,which leads indirectly to a modest reduction in LDL and increase in HDL. Longterm administration is associated with reduced mortality, but unwanted effects limit it's clinical use. Adverse effects include flushing ( associated with Prostaglandin D2 ), palpitations, and GIT distrubances. Flushing can be reduced by taking aspirin 20-30 min before. High doses can cause disorders of liver function, impair glucose tolerance and precipitate gout.
Raw materials: Chloroform-->Hydrogen peroxide-->Maleic anhydride -->5-Methyl-2-pyrazinecarboxylic acid
With cooling and stirring, adding 78g Maleic anhydride in 60ml chloroform solution,dissolved , adding 40ml 30% hydrogen peroxide. 2h later, adding 4.8g 5 - Methylpyrazine-2-carboxylic acid, at 0-5 °C, remain 2d. Filtered Maleic acid. Concentrated to a small residual volume, adding Ethyl acetate, filteried, obtaining 1.1g Acipimox.
