Prisinzano Date approved: July 18, 2012 ii ABSTRACT Kappa opioid (KOP) receptors have been suggested as an alternative target to the mu opioid (MOP) receptor for the treatment of pain because KOP activation is associated with fewer negative side-effects (respiratory depression, constipation, tolerance, and dependence). The KOP receptor has also been implicated in several abuse-related effects in the central nervous system (CNS). KOP ligands have been investigated as pharmacotherapies for drug abuse; KOP agonists have been shown to modulate dopamine concentrations in the CNS as well as attenuate the self-administration of cocaine in a variety of species, and KOP antagonists have potential in the treatment of relapse. One drawback of current opioid ligand investigation is that many compounds are based on the morphine scaffold and thus have similar properties, both positive and negative, to the parent molecule. Thus there is increasing need to discover new chemical scaffolds with opioid receptor activity.

ARTICLE INFO ABSTRACT Article history Amentoflavone, is a bioflavonoid constituent of some of flora which includes ginkgo biloba, Received 06/02/2017 hypericum perforatum. It can have interaction with many medicinal drugs by using being a Available online potent inhibitor of CYP3A4 and CYP2C9 which are enzymes chargeable for the metabolism 28/02/2017 of some drugs in the body. Flavonoids exhibit a extensive variety of activities including antioxidant, antiviral, Antibacterial and anticancer pastime. As formerly we showed that Keywords amentoflavone is an activator of hPPARγ. Human PPARγ (hPPARγ) regulates the Amentoflavone, proliferation, apoptosis, and various human most cancers cells. Activated hPPARγ has both Flavonoid, tumor suppressor and tumor promoter. To affirm the mechanism of motion of amentoflavone Synthetic, in most cancers cells, we analyzed whether or not amentoflavone remedy affects the RSV, Hpparγ, appearance of hPPARy the use of opposite transcription polymerase chain response and CYP3A4 & CYP2C9. actual time quantitive PCR. Amentoflavone is synthesized with the aid of way of three techniques i.e natural, semi synthetic and synthetic methods. Among this synthetic method is widely used industrially. Application of the Suzuki-Miyaura response within the synthesis of flavonoids, is of vital magnificence of natural merchandise, is studied. Amentoflavone and three different flavonoids were separated from the ethanol extract of Selaginella sinensis. Amentoflavone show strong antiviral pastime in opposition to respiratory syncytial virus (RSV). The cytotoxic interest of amentoflavone is examined against 5 human most cancers cell strains (MCF-7, A549, HeLa, MDA-MB231, and PC3) treating with tetrazolium- primarily based colorimetric MTT assay.

Although several therapeutic molecules are being tested, no effective vaccines or specific treatments have been developed. Since the COVID-19 outbreak, different traditional herbal medicines with promising results have been used alone or in combination with conventional drugs to treat infected patients. Here, we review the recent findings regarding the use of natural products to prevent or treat COVID-19 infection. Furthermore, the mechanisms responsible for this preventive or therapeutic effect are discussed. We conducted literature research using PubMed, Google Scholar, Scopus, and WHO website.

Evansd aDepartment of Biochemistry, Case Western Reserve University Medical School, Cleveland, OH, USA bDepartment of Neurosciences, Case Western Reserve University Medical School, Cleveland, OH, USA cDepartment of Psychiatry, Case Western Reserve University Medical School, Cleveland, OH, USA dNational Institute of Mental Health Psychoactive Drug Screening Program, Case Western Reserve University Medical School, Cleveland, OH, USA eDepartment of Medicinal Chemistry, Medical College of Virginia, Virginia Commonwealth University, Richmond, VA, USA Abstract Because psychoactive plants exert profound effects on human perception, emotion, and cognition, discovering the molecular mechanisms responsible for psychoactive plant actions will likely yield insights into the molecular underpinnings of human consciousness. Additionally, it is likely that elucidation of the molecular targets responsible for psychoactive drug actions will yield validated targets for CNS drug discovery. This review article focuses on an unbiased, discovery-based approach aimed at uncovering the molecular targets responsible for psychoactive drug actions wherein the main active ingredients of psychoactive plants are screened at the ‘‘receptorome’’ (that portion of the proteome encoding receptors). An overview of the receptorome is given and various in silico, public-domain resources are described. Newly developed tools for the in silico mining of data derived from the National Institute of Mental Health Psychoactive Drug Screening Program’s (NIMH-PDSP) Ki Database (Ki DB) are described in detail.

S. More than $34.4 billion (Spinks & Hollingsworth, 2009) Magnitude of CAM Use CAM costs are 11.2% of total out-of- pocket expenditures on health care More than 354 million visits to CAM practitioners and approximately 835 million purchases (NCCAM, 2010). Natural products, including herbs, are the most commonly used CAM therapies (CDC, 2008). Reasons for CAM Use Reasons for this popularity are many: 1). Allopathic medicine’s failure to yield cures, adverse effects of orthodox regimens, dissatisfaction with technical approaches, and lack of practitioner time (Push Factor). 2). Belief that CAM treatments are natural, with dramatic results reported in the media, empowerment/ personal control, philosophical congruence of the patient, and the CAM practitioner practicing the 3 T’s of touch, talk and time [Pull Factor (Furnham &Vincent, 2000; Straus, 2002)].

  • Deep Eutectic Solvents As Extraction Media for Valuable Flavonoids from Natural Sources
    applied sciences Review Deep Eutectic Solvents as Extraction Media for Valuable Flavonoids from Natural Sources Dimitris Skarpalezos and Anastasia Detsi * Laboratory of Organic Chemistry, Department of Chemical Sciences, School of Chemical Engineering, National Technical University of Athens, 15780 Zografou, Athens, Greece; [email protected] * Correspondence: [email protected] Received: 31 July 2019; Accepted: 30 September 2019; Published: 4 October 2019 Abstract: The present review article attempts to summarize the use of deep eutectic solvents in the extraction of flavonoids, one of the most important classes of plant secondary metabolites. All of the applications reviewed have reported success in isolation and extraction of the target compounds; competitive, if not superior, extraction rates compared with conventional solvents; and satisfactory behavior of the extract in the latter applications (such as direct analysis, synthesis, or catalysis), wherever attempted. Keywords: flavonoids; extraction; deep eutectic solvents (DES); natural deep eutectic solvents (NaDES) 1. Introduction The global turn towards green chemistry is an integral approach towards conventional chemical practices. Following this trend, both raw materials and processes are being re-evaluated from the ground up, combining the research for naturally, sustainably sourced raw materials with eco-friendly, cost effective, and lean processes. Research on multiple compound groups is being carried out globally, aiming at isolating substances with significant health, well-being, or other benefits from natural sources, through green methods. The present review focuses on the extraction of flavonoids, an immense category of compounds found in plants and natural products. Furthermore, the review is dedicated to conventional and novel extraction methods using classic or natural deep eutectic solvents, a new category of green solvents with exceptional solvent properties, as well as generally green behavior.
