Synthesis and biological evaluation of nigranoic acid esters as novel human neutrophil elastase inhibitors.[Pubmed:25560928]
Nat Prod Res. 2015;29(17):1650-6.
Human neutrophil elastase (HNE) has been implicated as a major contributor in the pathogenesis of diseases, such as lung disorders and other inflammatory diseases. A series of 12 new Nigranoic acid esters were regioselectively synthesised in good yields and evaluated for HNE inhibitory activity. Nigranoic acid exhibited significant inhibitory activity against HNE with the IC50 value of 3.77 muM, and six esters displayed considerable inhibitory effects on HNE with IC50 values in the range of 2.61-8.95 muM. The Nigranoic acid esters having phenyls substituted with bromine and trimethoxyls (3h and 3b) showed stronger inhibitory activity on HNE than Nigranoic acid.
Nigranoic acid, a triterpenoid from Schisandra sphaerandra that inhibits HIV-1 reverse transcriptase.[Pubmed:8778243]
J Nat Prod. 1996 May;59(5):525-7.
An A ring-secocycloartene triterpenoid, Nigranoic acid (3,4-secocycloarta-4(28),24-(Z)-diene-3,-26-dioic acid, (1) was isolated from the stems of Schisandra sphaerandra, a Chinese traditional medicinal plant. Its structure elucidation and unambiguous NMR spectral assignment were achieved by the combination of 1D- and 2D-NMR techniques with the aid of computer modeling. Nigranoic acid showed activity in several anti-HIV reverse transcriptase and polymerase assays.
Protective effects of nigranoic acid on cerebral ischemia-reperfusion injury and its mechanism involving apoptotic signaling pathway.[Pubmed:25168103]
Cell Biochem Biophys. 2015 Jan;71(1):345-51.
The goal of this study was to assess the expression of poly ADP-ribose polymerase (PARP) and apoptosis-inducing factor (AIF) in the hippocampal CA1 region, and to find out whether Nigranoic acid treatment exhibits protective effects on brain through PARP/AIF signaling pathway in cerebral ischemia-reperfusion animal model. Rats were randomly divided into three groups: Sham-surgery, ischemia-reperfusion, and Nigranoic acid-treated. Rat models of middle cerebral artery occlusion were prepared using a way of thread occlusion. Rats in the Nigranoic acid group were administered with 1 mg/kg intragastric Nigranoic acid 6 and 2 h before brain ischemia, respectively. Following reperfusion, samples were collected at different time-points (6, 24, and 72 h) and each group was further divided into three subgroups. Apoptosis was measured using the terminal deoxynucleotidyl-transferase-mediated dUTP nick end labeling method. The protein expression levels of AIF and PARP were detected using Western blot and AIF mRNA quantity was evaluated using the reverse transcription-polymerase chain reaction. Apoptosis, levels of AIF and PARP protein expression, and levels of AIF mRNA expression were significantly increased in the ischemia-reperfusion group compared with the sham-surgery group. However, apoptosis and the expression levels of AIF protein, PARP protein, and AIF mRNA at different time-points were significantly decreased in the Nigranoic acid-treated group compared with the model group. We can judge that Nigranoic acid has a strong protective effect on rat cerebral ischemia-reperfusion injury, and acts by downregulating nerve cell apoptosis by preventing the overactivation of PARP and AIF nuclear translocation.
Effect of nigranoic acid on Ca(2)(+) influx and its downstream signal mechanism in NGF-differentiated PC12 cells.[Pubmed:24674947]
J Ethnopharmacol. 2014 May 14;153(3):725-31.
ETHNOPHARMACOLOGICAL RELEVANCE: Schisandra chinensis has a long history of use as a famous traditional Chinese medicine. The plants of genus Schisandra, especially Schisandra neglecta, Schisandra rubriflora, and Schisandra sphaerandra are used in the same way as Schisandra chinensis in the folk medicine to treat insomnia, fatigue, increasing intelligence, and tranquilizing. Many studies showed that lignans were the major active components of Schisandra genus, whereas the bioactivity of abundant triterpenoids in Schisandra genus, such as Nigranoic acid (SBB1, 3,4-secocycloartene triterpenoid), has not been examined yet in neuropathology. MATERIALS AND METHODS: After treating with SBB1, intracellular Ca(2+) concentration was analyzed by Ca(2+) fluorescent indicator (Fluo-4 AM) in NGF-differentiated PC12 cells. Intracellular nitric oxide (NO) level was analyzed using NO fluorescent indicator (DAF-FM). The expression of extracellular signal regulated kinase 1 and 2 (ERK1/2) was analyzed by western blotting, and the temporal mRNA for BDNF and c-fos was analyzed using reverse transcription quantitative PCR. RESULT: We found that SBB1 induced Ca(2+) influx in a time- and concentration-dependent manner, which was significantly attenuated in Ca(2+) free media. SBB1 promoted the intracellular NO production which depended on increasing cytoplasmic Ca(2+) level. Moreover, SBB1 stimulated activation of ERK1/2 through Ca(2+)-CaMKII pathway. In addition, we found that SBB1 increased the expression of BDNF and c-fos mRNA. CONCLUSION: These results suggest that SBB1 is able to promote NO production and stimulate phosphorylation of ERK1/2 through Ca(2+) influx, further impact expression of BDNF and c-fos, which provides evidence for the effects of SBB1 that may be benefit to enhance mental and intellectual functions.
