Nicotinamide is a water-soluble vitamin, an active component of coenzymes NAD and NADP, and acts as poly (ADP-ribose) polymerase (PARP) inhibitor.

In Vitro

Pretreatment with the poly (ADP-ribose) polymerase (PARP) inhibitor nicotinamide is able to prevent HCN2 cell death. When nicotinamide is added prior to t-BuOOH, it is able to prevent neuronal cell death and inhibit apoptosis. Nicotinamide-pretreated neurons have higher expression levels of inhibitors of apoptosis (IAP) genes[1]. Nicotinamide inhibits vasoconstriction by ET. Nicotinamide also alleviates oxidative stress, which exacerbates PE and FGR[3].

In Vivo

Normal and streptozotocin-nicotinamide induced adult male diabetic rats receive quercetin (10, 25 and 50 mg/kg/bw) orally, and cause significant decrease in FBG and cardiac injury marker levels with increased in insulin levels[2]. Nicotinamide improves maternal hypertension, proteinuria, and glomerular endotheliosis in RUPP mice. Moreover, nicotinamide prolongs pregnancies, and improves survival and growth of the embryos in RUPP PE mice[3].

Animal Administration

Nicotinamide is dissolved in normal saline.

DM is induced via a single intraperitoneal (i.p) injection of nicotinamide (110 mg/kg/body weight) dissolved in normal saline 15 min prior to streptozotocin (STZ) (55 mg/kg/body weight) injection, which is dissolved in a freshly prepared 0.1mol/Lcitrate buffer (pH 4.5). These injections are given following an overnight fast. Control rats (n=6) are injected with the same amount of solvent. In order to prevent hypoglycemia in the first 24 h following STZ injection, rats are allowed to have free access to water with 5% dextrose (D5W). Three days after STZ-nicotinamide injection, rats with FBG levels greater than 7.0 mM are considered as diabetic. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
