烟酰胺用途

Nicotinamide是一种B3维生素,通过促进NAD +氧化还原稳态和提供NAD +作为催化非氧化还原反应的一类酶的底物,在细胞生理学中发挥重要作用。烟酰胺是 SIRT1 的抑制剂。

[体外研究]

用聚(ADP-核糖)聚合酶(PARP)抑制剂烟酰胺预处理能够预防HCN2细胞死亡。当在t-BuOOH之前加入烟酰胺时,它能够阻止神经元细胞死亡并抑制细胞凋亡。烟酰胺预处理的神经元具有更高的凋亡抑制因子(IAP)基因表达水平[1]。烟酰胺通过ET抑制血管收缩。烟酰胺还可以缓解氧化应激,从而加剧PE和FGR [3]。

[体内研究]

正常和链脲佐菌素-烟酰胺诱导的成年男性糖尿病大鼠口服槲皮素(10,25和50 mg/kg/bw),并导致FBG和心脏损伤标志物水平显着降低,胰岛素水平升高[2]。烟酰胺可改善RUPP小鼠的母体高血压,蛋白尿和肾小球内皮增生症。此外,烟酰胺可延长妊娠期,并可改善RUPP PE小鼠胚胎的存活和生长[3]。

[动物实验]

在注射链脲佐菌素（STZ）（55mg / kg /体重）前15分钟，通过单次腹膜内（ip）注射溶解于生理盐水中的烟酰胺（110mg / kg /体重）诱导DM，将其溶解于新鲜制备的0.1mol / Lcitrate缓冲液（pH4.5）。这些注射是在禁食过夜后给出的。对照大鼠（n = 6）注射相同量的溶剂。为了在STZ注射后的最初24小时内防止低血糖，允许大鼠用5％葡萄糖（D5W）自由饮水。注射STZ-烟酰胺后3天，FBG水平大于7.0mM的大鼠被认为是糖尿病。

烟酰胺制备

1、 β-甲基吡啶经空气氧化成烟酸，后者与氢氧化铵作用，再加热脱水制得。

2、将烟酸、硼酸和氨水投入反应锅，搅拌下通入氨气，升温溶解；然后蒸馏回收氨，至120~C后移入脱水锅内继续浓缩；当温度达145℃后开始加入液氨，并在185～190℃下继续通氨反应20～30h。然后降温至130℃，加蒸馏水稀释，加入活性炭，并在70~80~C下通氨脱色2h；反应后趁热过滤，滤液在水中冷析24h，分离结晶，并用乙醇洗涤、干燥得成品，收率89%。

3、由烟酸与氨水成盐后再脱水而得。
