  • Safranal, a Saffron Constituent, Attenuates Retinal Degeneration in P23H Rats
    Safranal, a Saffron Constituent, Attenuates Retinal Degeneration in P23H Rats Laura Ferna´ndez-Sa´nchez1., Pedro Lax1., Gema Esquiva1, Jose´ Martı´n-Nieto1, Isabel Pinilla2, Nicola´s Cuenca1* 1 Department of Physiology, Genetics and Microbiology, University of Alicante, Alicante, Spain, 2 Department of Ophthalmology, University Hospital Lozano Blesa, Zaragoza, Spain Abstract Saffron, an extract from Crocus sativus, has been largely used in traditional medicine for its antiapoptotic and anticarcinogenic properties. In this work, we investigate the effects of safranal, a component of saffron stigmas, in attenuating retinal degeneration in the P23H rat model of autosomal dominant retinitis pigmentosa. We demonstrate that administration of safranal to homozygous P23H line-3 rats preserves both photoreceptor morphology and number. Electroretinographic recordings showed higher a- and b-wave amplitudes under both photopic and scotopic conditions in safranal-treated versus non-treated animals. Furthermore, the capillary network in safranal-treated animals was preserved, unlike that found in untreated animals. Our findings indicate that dietary supplementation with safranal slows photoreceptor cell degeneration and ameliorates the loss of retinal function and vascular network disruption in P23H rats. This work also suggests that safranal could be potentially useful to retard retinal degeneration in patients with retinitis pigmentosa.

  • Yangonin Blocks Tumor Necrosis Factor-Α–Induced Nuclear Factor-Κb–Dependent Transcription by Inhibiting the Transactivation Potential of the Rela/P65 Subunit
    J Pharmacol Sci 118, 447 – 454 (2012) Journal of Pharmacological Sciences © The Japanese Pharmacological Society Full Paper Yangonin Blocks Tumor Necrosis Factor-α–Induced Nuclear Factor-κB–Dependent Transcription by Inhibiting the Transactivation Potential of the RelA/p65 Subunit Juan Ma1,†, He Liang1,†, Hong Ri Jin2, Nguyen Tien Dat3, Shan Yu Zhang1, Ying Zi Jiang1, Ji Xing Nan1, Donghao Li1, Xue Wu1, Jung Joon Lee1,2,*a, and Xuejun Jin1,*b 1Key Laboratory of Natural Resources of Changbai Mountain & Functional Molecules, Yanbian University, Ministry of Education, Yanji Jilin 133002, China 2Center for Molecular Cancer Research, Korea Research Institute of Bioscience and Biotechnology, Ochang, Chungbuk 363-883, Republic of Korea 3Institute of Marine Biochemistry, Vietnam Academy of Science and Technology, 18-Hoang Quoc Viet, Hanoi, Vietnam Received November 13, 2011; Accepted January 23, 2012 Abstract. The nuclear factor-κB (NF-κB) transcription factors control many physiological pro- cesses including inflammation, immunity, and apoptosis. In our search for NF-κB inhibitors from natural resources, we identified yangonin from Piper methysticum as an inhibitor of NF-κB activa- tion. In the present study, we demonstrate that yangonin potently inhibits NF-κB activation through suppression of the transcriptional activity of the RelA/p65 subunit of NF-κB. This compound sig- nificantly inhibited the induced expression of the NF-κB-reporter gene. However, this compound did not interfere with tumor necrosis factor-α (TNF-α)-induced inhibitor of κBα (IκBα) degrada- tion, p65 nuclear translocation, and DNA-binding activity of NF-κB. Further analysis revealed that yangonin inhibited not only the induced NF-κB activation by overexpression of RelA/p65, but also transactivation activity of RelA/p65.

  • Herbal Insomnia Medications That Target Gabaergic Systems: a Review of the Psychopharmacological Evidence
    Send Orders for Reprints to [email protected] Current Neuropharmacology, 2014, 12, 000-000 1 Herbal Insomnia Medications that Target GABAergic Systems: A Review of the Psychopharmacological Evidence Yuan Shia, Jing-Wen Donga, Jiang-He Zhaob, Li-Na Tanga and Jian-Jun Zhanga,* aState Key Laboratory of Bioactive Substance and Function of Natural Medicines, Institute of Materia Medica, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, P.R. China; bDepartment of Pharmacology, School of Marine, Shandong University, Weihai, P.R. China Abstract: Insomnia is a common sleep disorder which is prevalent in women and the elderly. Current insomnia drugs mainly target the -aminobutyric acid (GABA) receptor, melatonin receptor, histamine receptor, orexin, and serotonin receptor. GABAA receptor modulators are ordinarily used to manage insomnia, but they are known to affect sleep maintenance, including residual effects, tolerance, and dependence. In an effort to discover new drugs that relieve insomnia symptoms while avoiding side effects, numerous studies focusing on the neurotransmitter GABA and herbal medicines have been conducted. Traditional herbal medicines, such as Piper methysticum and the seed of Zizyphus jujuba Mill var. spinosa, have been widely reported to improve sleep and other mental disorders. These herbal medicines have been applied for many years in folk medicine, and extracts of these medicines have been used to study their pharmacological actions and mechanisms. Although effective and relatively safe, natural plant products have some side effects, such as hepatotoxicity and skin reactions effects of Piper methysticum. In addition, there are insufficient evidences to certify the safety of most traditional herbal medicine. In this review, we provide an overview of the current state of knowledge regarding a variety of natural plant products that are commonly used to treat insomnia to facilitate future studies.

  • Antidepressant-Like Behavioral and Neurochemical Effects of the Citrus
    Available online at www.sciencedirect.com Life Sciences 82 (2008) 741–751 www.elsevier.com/locate/lifescie Antidepressant-like behavioral and neurochemical effects of the citrus-associated chemical apigenin ⁎ Li-Tao Yi, Jian-Mei Li, Yu-Cheng Li, Ying Pan, Qun Xu, Ling-Dong Kong State Key Laboratory of Pharmaceutical Biotechnology, School of Life Sciences, Nanjing University, Nanjing 210093, PR China Received 14 July 2007; accepted 16 January 2008 Abstract Apigenin is one type of bioflavonoid widely found in citrus fruits, which possesses a variety of pharmacological actions on the central nervous system. A previous study showed that acute intraperitoneal administration of apigenin had antidepressant-like effects in the forced swimming test (FST) in ddY mice. To better understand its pharmacological activity, we investigated the behavioral effects of chronic oral apigenin treatment in the FST in male ICR mice and male Wistar rats exposed to chronic mild stress (CMS). The effects of apigenin on central monoaminergic neurotransmitter systems, the hypothalamic–pituitary–adrenal (HPA) axis and platelet adenylyl cyclase activity were simultaneously examined in the CMS rats. Apigenin reduced immobility time in the mouse FST and reversed CMS-induced decrease in sucrose intake of rats. Apigenin also attenuated CMS-induced alterations in serotonin (5-HT), its metabolite 5-hydroxyindoleacetic acid (5-HIAA), dopamine (DA) levels and 5-HIAA/ 5-HT ratio in distinct rat brain regions. Moreover, apigenin reversed CMS-induced elevation in serum corticosterone concentrations and reduction in platelet adenylyl cyclase activity in rats. These results suggest that the antidepressant-like actions of oral apigenin treatment could be related to a combination of multiple biochemical effects, and might help to elucidate its mechanisms of action that are involved in normalization of stress- induced changes in brain monoamine levels, the HPA axis, and the platelet adenylyl cyclase activity.

Aromatase, encoded by the cytochrome P450 19 (CYP19) gene, regulates estrogen biosynthesis. This study aimed to identify active flavones that inhibit CYP19 expression and to explore the underlying mechanisms. CYP19 expression was evaluated using reverse transcription PCR, quantitative real-time PCR, and immunoblot analysis. The role of transcription factor early growth response gene 1 (EGR-1) in CYP19 expression was assessed using the short-hairpin RNA (shRNA)-mediated knockdown of EGR-1 expression in estrogen receptor-positive MCF-7 breast cancer cells. We screened 39 flavonoids containing 26 flavones and 13 flavanones using the EGR1 promoter reporter activity assay and observed that chrysoeriol exerted the highest inhibitory activity on tumor necrosis factor alpha (TNFα)-induced EGR-1 expression.
