Nicotinamide(烟酰胺,又称Vitamin B3),是sirtuins的非竞争性抑制剂,该抑制作用影响体内外多种重要的调控机制。Nicotinamide强烈抑制酵母SIR2介导的转录沉默,增加rDNA重组,并缩短复制寿命。酵母酶PNC1可将nicotinamide转化为烟酸(nicotinic acid),用于激活Sir2,阻止nicotinamide对端粒的抑制作用和rDNA沉默。Nicotinamide抑制p53的...

Vitamin B3 completes these important functions because it’s part of two coenzymes—nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). Don’t get hung up on the long, complicated names. Focus on their functions. NAD and NADP are very similar in function...

Niacin (vitamin B3) is inclusive of nicotinic acid and nicotinamide (Fig.2) which are converted to their mononucleotide forms by nicotinate phosphoribosyltransferase (NAPRT) and nicotinamide phosphoribosyltransferase (NAMPT) respectively [53]. Both forms of the mononucleotide are subsequently converted to...
