The Phytochemistry of Cherokee Aromatic Medicinal Plants
medicines Review The Phytochemistry of Cherokee Aromatic Medicinal Plants William N. Setzer 1,2 1 Department of Chemistry, University of Alabama in Huntsville, Huntsville, AL 35899, USA; [email protected]; Tel.: +1-256-824-6519 2 Aromatic Plant Research Center, 230 N 1200 E, Suite 102, Lehi, UT 84043, USA Received: 25 October 2018; Accepted: 8 November 2018; Published: 12 November 2018 Abstract: Background: Native Americans have had a rich ethnobotanical heritage for treating diseases, ailments, and injuries. Cherokee traditional medicine has provided numerous aromatic and medicinal plants that not only were used by the Cherokee people, but were also adopted for use by European settlers in North America. Methods: The aim of this review was to examine the Cherokee ethnobotanical literature and the published phytochemical investigations on Cherokee medicinal plants and to correlate phytochemical constituents with traditional uses and biological activities. Results: Several Cherokee medicinal plants are still in use today as herbal medicines, including, for example, yarrow (Achillea millefolium), black cohosh (Cimicifuga racemosa), American ginseng (Panax quinquefolius), and blue skullcap (Scutellaria lateriflora). This review presents a summary of the traditional uses, phytochemical constituents, and biological activities of Cherokee aromatic and medicinal plants. Conclusions: The list is not complete, however, as there is still much work needed in phytochemical investigation and pharmacological evaluation of many traditional herbal medicines. Keywords: Cherokee; Native American; traditional herbal medicine; chemical constituents; pharmacology 1. Introduction Natural products have been an important source of medicinal agents throughout history and modern medicine continues to rely on traditional knowledge for treatment of human maladies [1]. Traditional medicines such as Traditional Chinese Medicine [2], Ayurvedic [3], and medicinal plants from Latin America [4] have proven to be rich resources of biologically active compounds and potential new drugs. -

These authors contributed equally to this work. y Received: 20 December 2019; Accepted: 18 January 2020; Published: 20 January 2020 Abstract: Thrombin, a key enzyme of the serine protease superfamily, plays an integral role in the blood coagulation cascade and thrombotic diseases. In view of this, it is worthwhile to establish a method to screen thrombin inhibitors (such as natural flavonoid-type inhibitors) as well as investigate their structure activity relationships. Virtual screening using molecular docking technique was used to screen 103 flavonoids. Out of this number, 42 target compounds were selected, and their inhibitory effects on thrombin assayed by chromogenic substrate method. The results indicated that the carbon-carbon double bond group at the C2, C3 sites and the carbonyl group at the C4 sites of flavones were essential for thrombin inhibition, whereas the methoxy and O-glycosyl groups reduced thrombin inhibition. -

Current study involves the screening and identification of potent inhibitors of the pneumococcal virulence factor pneumolysin. About 100 flavonoids were chosen from scientific literature and docked with pnuemolysin (PDB Id.: 4QQA) using Patch Dockprogram for molecular docking. The results obtained were analysed and the docked structures visualized using LigPlus software. It was found that flavonoids amurensin, diosmin, robinin, rutin, sophoroflavonoloside, spiraeoside and icariin had hydrogen bond interactions with the receptor protein pneumolysin (4QQA). Among others, robinin had the highest score (7710) revealing that it had the best geometrical fit to the receptor molecule forming 12 hydrogen bonds ranging from 0.8-3.3 Å. Keywords : Pneumococci, pneumolysin, flavonoids, antimicrobial, virtual screening _____________________________________________________________________________________________ INTRODUCTION Streptococcus pneumoniae is a gram positive pathogenic bacterium causing opportunistic infections that may be life-threating[1]. Pneumococcus is the causative agent of pneumonia and is the most common agent causing meningitis. -

Therefore, it has been postulated as a molecule with great therapeutic potential. The renoprotective capacity of quercetin against various toxins that produce oxidative stress, in both in vivo and in vitro models, has been shown. However, it is not clear whether quercetin itself or any of its metabolites are responsible for the protective effects on the kidney. Although the pharmacokinetics of quercetin have been widely studied and the complexity of its transit throughout the body is well known, the metabolic processes that occur in the kidney are less known. Because of that, the objective of this review was to delve into the molecular and cellular events triggered Citation: Muñoz-Reyes, D.; Morales, by quercetin and/or its metabolites in the tubular cells, which could explain some of the protective A.I.; Prieto, M. -

The majority of structures found were flavones and flavonols, sometimes with 6- and/or 8-substitution, and with a varying degree of oxidation and methylation. Flava- nones were observed in exudates of some genera, and, in some cases, also flavonol- and flavone glycosides were detected. This was mostly the case when exudates were poor both in yield and chemical complexity. Structurally diverse profiles are found particularly within Astereae and Heliantheae. The tribes in the subfamily Cichorioideae exhibited less complex flavonoid profiles. Current results are compared to literature data, and botanical information is included on the studied taxa.
