  • 5-HT Receptor Agonist Befiradol Reduces Fentanyl-Induced
    5-HT1A Receptor Agonist Befiradol Reduces Fentanyl-induced Respiratory Depression, Analgesia, and Sedation in Rats Jun Ren, Ph.D., Xiuqing Ding, B.Sc., John J. Greer, Ph.D. ABSTRACT Background: There is an unmet clinical need to develop a pharmacological therapy to counter opioid-induced respiratory depression without interfering with analgesia or behavior. Several studies have demonstrated that 5-HT1A receptor agonists alleviate opioid-induced respiratory depression in rodent models. However, there are conflicting reports regarding their effects on analgesia due in part to varied agonist receptor selectivity and presence of anesthesia. Therefore the authors performed a Downloaded from http://pubs.asahq.org/anesthesiology/article-pdf/122/2/424/267207/20150200_0-00031.pdf by guest on 27 September 2021 study in rats with befiradol (F13640 and NLX-112), a highly selective 5-HT1A receptor agonist without anesthesia. Methods: Respiratory neural discharge was measured using in vitro preparations. Plethysmographic recording, nociception testing, and righting reflex were used to examine respiratory ventilation, analgesia, and sedation, respectively. Results: Befiradol (0.2 mg/kg, n = 6) reduced fentanyl-induced respiratory depression (53.7 ± 5.7% of control minute ven- tilation 4 min after befiradol vs. saline 18.7 ± 2.2% of control, n = 9; P < 0.001), duration of analgesia (90.4 ± 11.6 min vs. saline 130.5 ± 7.8 min; P = 0.011), duration of sedation (39.8 ± 4 min vs. saline 58 ± 4.4 min; P = 0.013); and induced baseline hyperventilation, hyperalgesia, and “behavioral syndrome” in nonsedated rats. Further, the befiradol-induced alleviation of opioid-induced respiratory depression involves sites or mechanisms not functioning in vitro brainstem–spinal cord and medul- lary slice preparations.

  • Novel Cyclodextrin Derivatives Presented at the 3Rd European Conference on Cyclodextrins
    VOLUME 27. No. 11. NOVEMBER 2013 ISSN 0951-256X October 2-4, 2013, Antalya, Turkey Novel cyclodextrin derivatives presented at the 3rd European Conference on Cyclodextrins This year’s European Conference on Cyclodextrins organized by Prof. Erem Bilensoy, Hacettepe University, Ankara brought 50 oral presentations and 65 posters. Most of the presented works covered the main theme of the congress: ”multifunctional excipient potential of cyclodextrins in pharmaceutical, cosmetic and biomedical industries”. The large number of the presented works dealing with novel cyclodextrin derivatives clearly shows that recently there has been a renewed interest in functionalization of cyclodextrins in order to extend the utilization of these derivatives as tools in catalysis, drug delivery, formulation and stabilization of active molecules and cosmetic ingredients. This short paper gives a brief review of the presented novel cyclodextrin derivatives, summarizes their synthetic methodologies and the field of their applications. Extended abstracts will be published in the Journal of Inclusion Phenomena and Macrocyclic Chemistry after peer review. The references given here are the papers of the cited authors on similar topics presented at the conference. NOVEL CYCLODEXTRIN POLYMERS AND NANOSPONGES Phosphorus-containing cyclodextrin polymers presented by Prof. Catherine Amiel A very attractive new cyclodextrin (CD) based polymeric system presented by Prof. Amiel combines the advantages of cyclodextrin polymers (formation of inclusion complexes with apolar guests) and phosphorus-containing polymers (biocompatibility, calcium affinity).

  • Diagnosis and Treatment of Parkinson Disease: Molecules to Medicine
    Diagnosis and treatment of Parkinson disease: molecules to medicine Joseph M. Savitt, … , Valina L. Dawson, Ted M. Dawson J Clin Invest. 2006;116(7):1744-1754. https://doi.org/10.1172/JCI29178. Science in Medicine Parkinson disease (PD) is a relatively common disorder of the nervous system that afflicts patients later in life with tremor, slowness of movement, gait instability, and rigidity. Treatment of these cardinal features of the disease is a success story of modern science and medicine, as a great deal of disability can be alleviated through the pharmacological correction of brain dopamine deficiency. Unfortunately these therapies only provide temporary, though significant, relief from early symptoms and do not halt disease progression. In addition, pathological changes outside of the motor system leading to cognitive, autonomic, and psychiatric symptoms are not sufficiently treated by current therapies. Much as the discovery of dopamine deficiency led to powerful treatments for motor symptoms, recent discoveries concerning the role of specific genes in PD pathology will lead to the next revolution in disease therapy. Understanding why and how susceptible cells in motor and nonmotor regions of the brain die in PD is the first step toward preventing this cell death and curing or slowing the disease. In this review we discuss recent discoveries in the fields of diagnosis and treatment of PD and focus on how a better understanding of disease mechanisms gained through the study of monogenetic forms of PD has provided novel therapeutic targets.

  • Yasakli Maddeler
    YASAKLI MADDELER Ülkemizde yarış atlarında kullanılan/kullanılma ihtimali olan ilaçların/maddelerin belirlenmesinde; ilacın farmakolojisi (öncelikle etkisi, etki grubu), farmasötik şekli, kullanılma yolu, kullanılma alanı, yarış sonucunu etkileme durumu, ulusal mevzuata göre veteriner hekimlikte ve/veya yarış atlarında kullanmak için ruhsatlı/izinli olup-olmama durumu, etiket-dışı kullanılma gibi hususlar dikkate alınmıştır. Eşik değeri (Threshold level) olan maddelerin (vücutta şekillenirler, çevre ve yem kaynaklı olabilirler) miktarı, belirlenen miktarı aştığında yasaklı-madde kullanılması/doping ihlali olarak değerlendirilir. Tedavide kullanılan/tarama limiti (Screening level) olan maddelerle ilgili değerlendirmede; bu maddelerle ilgili olarak yapılan doping analizlerinde ölçülen miktar, idrarda/plazmada belirlenen tarama değerini aştığında yasaklı madde kullanılması/doping-ihlali olarakdeğerlendirilir. Ana madde yanında, izomeri, metaboliti, metabolit izomeri, tuzları, esterleri, eterleri, diğer türevleri, ön-ilaç da yasaklı-madde listesinde yer alır; doping analizinde ortaya konulmaları doping ihlali olarak değerlendirilir. Maddeler ve yasaklı uygulamalar 6 başlık altında toplanmıştır. Bu liste ilgili uluslararası kuruluşların mevzuat ve düzenlemeleri ile ilgili maddelerin Farmakolojik özellikleri ve etkileri dikkate alınarak hazırlanmıştır. 1. YasaklıMaddeler Yasaklı maddeler; yarış atlarında tıbbi olarak kullanım yeri olmayan, atın yarış performansını açık şekilde etkileyen maddelerdir. İllegal kullanılan maddeler (Türkiye’de veteriner

  • Datasheet Inhibitors / Agonists / Screening Libraries a DRUG SCREENING EXPERT
    Datasheet Inhibitors / Agonists / Screening Libraries A DRUG SCREENING EXPERT Product Name : Volinanserin Catalog Number : T5389 CAS Number : 139290-65-6 Molecular Formula : C22H28FNO3 Molecular Weight : 373.46 Description: Volinanserin (MDL 100907) is a potent and selective antagonist of the serotonin receptor 5-HT2 (Ki: 0.36 nM) and shows 300-fold selectivity for 5-HT2 receptor over 5-HT1c, alpha-1 adrenergic and sigma receptors. Storage: 2 years -80°C in solvent; 3 years -20°C powder; DMSO 100 mg/mL (267.8 mM) Solubility Ethanol 18 mg/mL (48.2 mM) ( < 1 mg/ml refers to the product slightly soluble or insoluble ) Receptor (IC50) 5-HT2 receptor 0.36 nM (Ki) In vitro Activity MDL 100,907 demonstrated low nanomolar or subnanomolar binding in vitro at the 5-HT2A receptor and showed a > 100-fold separation from all other receptors measured. MDL 100,907 had subnanomolar potency as a 5-HT2A antagonist in vitro in reversing 5-HT-stimulated inositol phosphate accumulation in NIH 3T3 cells transfected with the rat 5-HT2A receptor [2]. In vivo Activity In mice, MDL 100,907 blocked amphetamine-stimulated locomotion at doses that did not significantly affect apomorphine- stimulated climbing behavior. When administered chronically, MDL 100,907 selectively reduced the number of spontaneously active A10 neurons [1]. In vivo, MDL 100,907 potently inhibited 5-methoxy-N, N-dimethyltryptamine-induced head twitches in mice or 5-hydroxytryptophan-induced head twitches in rats. In vivo, functional tests in mice revealed a > 500-fold separation between doses that produced 5-HT2A antagonism and doses that produced alpha 1-adrenergic or striatal D2 antagonism [2].
