Confronted by a steadily increasing number of secondary metabolites and a growing number of molecular targets relevant in the therapy of human disorders, the huge amount of information needs to be handled. Virtual screening filtering experiments already showed great promise for dealing with large libraries of potential bioactive molecules. It can be utilized for browsing databases for molecules fitting either an established pharma- cophore model or a three dimensional (3D) structure of a macromolecular target. However, for the discovery of natural lead candidates the application of this in silico tool has so far almost been neglected. There are several reasons for that. One concerns the scarce availability of natural product (NP) 3D databases in contrast to synthetic libraries; another reason is the problematic compatibility of NPs with modern robotized high throughput screening (HTS) technologies.

  • 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.

Mamadalieva 1,* and Michael Wink 2 1 Institute of the Chemistry of Plant Substances, Academy of Sciences, Mirzo Ulugbek str. 77, 100170 Tashkent, Uzbekistan; [email protected] 2 Institute of Pharmacy and Molecular Biotechnology, Heidelberg University, Im Neuenheimer Feld 364, 69120 Heidelberg, Germany; [email protected] * Correspondence: [email protected]; Tel.: +9-987-126-25913 Academic Editor: Ipek Kurtboke Received: 22 November 2016; Accepted: 13 February 2017; Published: 17 February 2017 Abstract: The mountains of Central Asia with 70 large and small mountain ranges represent species-rich plant biodiversity hotspots. Major mountains include Saur, Tarbagatai, Dzungarian Alatau, Tien Shan, Pamir-Alai and Kopet Dag. Because a range of altitudinal belts exists, the region is characterized by high biological diversity at ecosystem, species and population levels. In addition, the contact between Asian and Mediterranean flora in Central Asia has created unique plant communities. More than 8100 plant species have been recorded for the territory of Central Asia; about 5000–6000 of them grow in the mountains. The aim of this review is to summarize all the available data from 1930 to date on alkaloid-containing plants of the Central Asian mountains. In Saur 301 of a total of 661 species, in Tarbagatai 487 out of 1195, in Dzungarian Alatau 699 out of 1080, in Tien Shan 1177 out of 3251, in Pamir-Alai 1165 out of 3422 and in Kopet Dag 438 out of 1942 species produce alkaloids. The review also tabulates the individual alkaloids which were detected in the plants from the Central Asian mountains.

Box 80216, Jeddah 21589, Kingdom of Saudi Arabia 2Department of Biochemistry, All India Institute of Medical Sciences, New Delhi, 110029, India 3Department of Clinical Biochemistry, University of Kashmir, Hazratbal, Srinagar, 190006, India Abstract: Alzheimer’s disease (AD) is one of the major neurodegenerative diseases affecting almost 28 million people around the globe. It consistently remains one of the major health concerns of present world. Due to the clinical limitations like severe side effects of some synthesized drugs, alternative forms of treatments are gaining global acceptance in the treatment of AD. Neuroprotective compounds of natural origin and their synthetic derivatives exhibit promising results with minimal side effects and some of them are in their different phases of clinical trials. Alkaloids and their synthetic derivatives form one of the groups which have been used in treatment of neurodegenerative diseases like AD. We have further grouped these alkaloids into different sub groups like Indoles, piperdine and isoquinolines. Polyphenols form another important class of natural compounds used in AD management. Keywords: Alkaloids, polyphenols, Alzheimer’s disease, neuroprotective function. INTRODUCTION been proposed as one of the alternative forms of the treatment. Large number of these molecules have been Alzheimer’s disease (AD) is the most common type of reported to play significant roles in removal of deficiency of dementia and it accounts for an estimated 60 to 80 percent of neurotransmitters either by increasing their level using reported cases of dementia [1].

Abstract: Croton hirtus L’Hér methanol extract was studied by NMR and two different LC-DAD-MSn using electrospray (ESI) and atmospheric pressure chemical ionization (APCI) sources to obtain a quali-quantitative fingerprint. Forty different phytochemicals were identified, and twenty of them were quantified, whereas the main constituents were dihydro α ionol-O-[arabinosil(1-6) glucoside] (133 mg/g), dihydro β ionol-O-[arabinosil(1-6) glucoside] (80 mg/g), β-sitosterol (49 mg/g), and Citation: Dall’Acqua, S.; Sinan, K.I.; isorhamnetin-3-O-rutinoside (26 mg/g). C. hirtus was extracted with different solvents—namely, Sut, S.; Ferrarese, I.; Etienne, O.K.; water, methanol, dichloromethane, and ethyl acetate—and the extracts were assayed using different Mahomoodally, M.F.; Lobine, D.; in vitro tests.
