Parallel-Group,Double-Blind,Double-Dummy,Superiority Study of Etoricoxib90mg/ Cyclobenzaprine15mg From Eurofarma Versus Etoricoxib90mg (Arcoxia®) and Cyclobenzaprine15mg (XL - Mitrul®) for Muscle Spasm After Third Molar Extraction in Brazil

Etoricoxib and cyclobenzaprine hydrochloride are active pharmaceutical ingredients (APIs) already registered in the country as mono-drugs. These products are widely used for the proposed indications, and their safety and efficacy profiles are known in daily clinical practice. Once the absence of a pharmacokinetic interaction between etoricoxib and cyclobenzaprine hydrochloride has been confirmed in relative bioavailability studies, this phase 3 study will be conducted for demonstrating the superiority of the new FDC over etoricoxib 90 mg (Arcoxia®) and cyclobenzaprine hydrochloride 15 mg (XL - Mitrul®) in the treatment of moderate to serious pain associated with muscle spasm. The purpose is to provide a new, effective, and safe therapeutic option to address these cases.

Carotid dysfunction in senescent female mice is mediated by increased α_1A‐adrenoceptor activity and COX-derived vasoconstrictor prostanoids

Article

作者: Jimenez-Altayó, Francesc ; Gomes, Felipe V. ; Barros, Paula R. ; Costa-Neto, Claudio M. ; Santos-Silva, Thamyris ; Akamine, Eliana H. ; Dantas, Ana Paula ; Hott, Sara Cristina ; Costa, Tiago J. ; Tostes, Rita C. ; Silva-Neto, Júlio A. ; McCarthy, Cameron G. ; Duarte, Diego A.

The present study provides evidence that senescence induces hyperreactivity of α1-adrenoceptor-mediated contraction of the common carotid. Impairment of α1-adrenoceptor responses is linked to increased Ca2+ influx and release of COX-derived vasoconstrictor prostanoids, contributing to carotid dysfunction in the murine model of female senescence (SAMP8). Increased reactivity of the common carotid artery during senescence may lead to morphological and functional changes in arteries of the cerebral microcirculation and contribute to cognitive decline in females. Because the elderly population is growing, elucidating the mechanisms of aging- and sex-associated vascular dysfunction is critical to better direct pharmacological and lifestyle interventions to prevent cardiovascular risk in both sexes.

Role of Noradrenaline and Adrenoreceptors in Regulating Prostaglandin E2 Synthesis Cascade in Inflamed Endometrium of Pigs.

Article

作者: Bulc, Michal ; Witek, Krzysztof ; Jana, Barbara ; Calka, Jaroslaw

In the inflamed uterus, the production and secretion of prostaglandins (PGs) and noradrenergic innervation pattern are changed. Receptor-based control of prostaglandin E2 (PGE2) production and secretion by noradrenaline during uterine inflammation is unknown. The aim of this study was to determine the role of α1-, α2- and β-adrenoreceptors (ARs) in noradrenaline-influenced PG-endoperoxidase synthase-2 (PTGS-2) and microsomal PTGE synthase-1 (mPTGES-1) protein levels in the inflamed pig endometrium, and in the secretion of PGE2 from this tissue. E. coli suspension (E. coli group) or saline (CON group) was injected into the uterine horns. Eight days later, severe acute endometritis developed in the E. coli group. Endometrial explants were incubated with noradrenaline and/or α1-, α2- and β-AR antagonists. In the CON group, noradrenaline did not significantly change PTGS-2 and mPTGES-1 protein expression and increased PGE2 secretion compared to the control values (untreated tissue). In the E. coli group, both enzyme expression and PGE2 release were stimulated by noradrenaline, and these values were higher versus the CON group. The antagonists of α1- and α2-AR isoforms and β-AR subtypes do not significantly alter the noradrenaline effect on PTGS-2 and mPTGES-1 protein levels in the CON group, compared to noradrenaline action alone. In this group, α1A-, α2B- and β2-AR antagonists partly eliminated noradrenaline-stimulated PGE2 release. Compared to the noradrenaline effect alone, α1A-, α1B-, α2A-, α2B-, β1-, β2- and β3-AR antagonists together with noradrenaline reduced PTGS-2 protein expression in the E. coli group. Such effects were also exerted in this group by α1A-, α1D-, α2A-, β2- and β3-AR antagonists with noradrenaline on mPTGES-1 protein levels. In the E. coli group, the antagonists of all isoforms of α1-ARs and subtypes of β-ARs as well as α2A-ARs together with noradrenaline decreased PGE2 secretion versus noradrenaline action alone. Summarizing, in the inflamed pig endometrium, α1(A, B)-, α2(A, B)- and β(1, 2, 3)-ARs mediate the noradrenaline stimulatory effect on PTGE-2 protein expression, while noradrenaline via α1(A, D)-, α2A- and β(2, 3)-ARs increases mPTGES-1 protein expression and α1(A, B, D)-, α2A- and β(1, 2, 3)-ARs are involved in PGE2 release. Data suggest that noradrenaline may indirectly affect the processes regulated by PGE2 by influencing its production. Pharmacological modulation of particular AR isoforms/subtypes can be used to change PGE2 synthesis/secretion to alleviate inflammation and improve uterine function.

The Mechanism of Crocetin Targeting Cardiovascular Disease Based on Network Pharmacology Constrained by Spectral Experiments

Article

作者: Geng, Zhaoming ; Pan, Lanying ; Zhou, Qingteng ; Guo, Ming

AbstractThe network pharmacology under conditions is a recent development trend. We use network pharmacology methods to analyze the mechanism of crocetin (CRO) that regulates cardiovascular diseases. In this work, the spectral experimental data of CRO‐Protein interaction is first time combined with constraint conditions to solve the problems of targeting redundancy and lack of verification. CRO targets and cardiovascular disease targets were obtained by the target database. The STRING platform was used for PPI analysis. The GO and KEGG pathways of the target were analyzed using the Metascape platform; The core functional targets of CRO were screened by molecular docking techniques and the spectra of CRO and human serum albumin (HSA). Under the collaborative constraint conditions, the core targets of CRO that regulate cardiovascular diseases are ADRA1A, ADRA1B, CHRM1, CHRM2, GABRA1, and PTGS2; This study incorporates spectroscopy and molecular docking as constraints into the network pharmacological analysis, which significantly improves the credibility of network pharmacological analysis compared with unconstrained conditions. This method provides theoretical references for the in‐depth study of the mechanism between active substances and protein targets for other medicines in network pharmacology.
