Cytoplasmic Content

Autophagy is an essential cellular process that involves the transport of cytoplasmic content in double-membraned vesicles to lysosomes for degradation. Neurons do not undergo cytokinesis, and thus, the cell division process cannot reduce levels of unnecessary proteins. The primary cause of neurodegenerative disorders (NDs) is the abnormal deposition of proteins inside neuronal cells, and this could be averted by autophagic degradation. Thus, autophagy is an important consideration when considering means of developing treatments for NDs. Various pharmacological studies have reported that the active components in herbal medicines exhibit therapeutic benefits in NDs, for example, by inhibiting cholinesterase activity and modulating amyloid beta levels, and α-synuclein metabolism. A variety of bioactive constituents from medicinal plants are viewed as promising autophagy controllers and are revealed to recover the NDs by targeting the autophagic pathway. In the present review, we discuss the role of autophagy in the therapeutic management of several NDs. The molecular process responsible for autophagy and its importance in various NDs and the beneficial effects of medicinal plants in NDs by targeting autophagy are also discussed.

AbstractNeuropathy is defined as the damage to the peripheral or central nervous system accompanied by pain, numbness, or muscle weakness, which can be due to congenital diseases or environmental factors such as diabetes, trauma, or viral infections. As current treatments are not sufficiently able to control the disease, studies focusing on the identification and discovery of new therapeutic agents are necessary. Natural products have been used for a long time for the management of different neurological problems including neuropathies. The aim of the present study is to review the current clinical data on the beneficial effects of medicinal plants in neuropathy. Electronic databases including PubMed, Scopus, and Cochrane Library were searched with the keywords ‘neuropathy’ in the title/abstract and ‘plant’ or ‘extract’ or ‘herb’ in the whole text from inception until August 2017. From a total of 3679 papers, 22 studies were finally included. Medicinal plants were evaluated clinically in several types of neuropathy, including diabetic neuropathy, chemotherapy-induced peripheral neuropathy, carpal tunnel syndrome, and HIV-associated neuropathy. Some studies reported the improvement in pain, nerve function, nerve conduction velocity, and quality of life.Cannabis sativa(hemp),Linum usitatissimum(linseed oil), capsaicin, and a polyherbal Japanese formulation called Goshajinkigan had the most evidence regarding their clinical efficacy. Other investigated herbal medicines in neuropathy, such asMatricaria chamomilla(chamomile),Curcuma longa(turmeric), andCitrullus colocynthis(colocynth), had only one clinical trial. Thus, future studies are necessary to confirm the safety and efficacy of such natural medicines as a complementary or alternative treatment for neuropathy.

Natural Medicine

The use of medicinal plants is increasing due to the lack of side effects caused and the number of bioactive compounds that cannot be represented by synthetic chemical synthesis compounds. However, the management and use of natural medicines for the main handling of diseases are often hampered by the quality of the ingredients which are low and unstable. The standardized quality control system of OAI (Indonesian Natural Medicine) is the main key to improve clinical assurance and safety of the use of herbal medicines in Indonesia. One of the medicinal plants known to the public is Curcuma longa L. (turmeric). The main active components contained in turmeric are curcumin, demetoksikurkumin, bis-demetoksikurkumin, and ar-turmeron. Information about the quality of turmeric is needed in its use as a raw material for drugs so we need an analytical technique that is able to identify the diversity of metabolite profiles of active compounds. In this research, an optimization method is used to improve efficiency in the extraction of turmeric rhizome metabolites so that the best solvent concentration is known for the analysis of fingerprinting secondary metabolites with 1H-NMR 500 MHz spectroscopy in turmeric rhizomes. The results were analyzed with MNOVA software and chemical shift obtained compared with the reference. From the results obtained a concentration of methanol-d4 (CD3OD) 100% able to extract curcumin better than other solvents. The solvent is able to extract saccharide (sugar) compounds in the form of sucrose, amino acids and fatty acids in the form of methionine, glutamine, acetate, and glycero phospho choline.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) outbreak was first reported in Wuhan, a city in Hubei Province of China in December, 2019 and is known to be responsible for the novel coronavirus disease (COVID-19). COVID-19 was declared a pandemic in March, 2020 and since then, it has caused a number of deaths in over 200 countries around the world. Extensive researches have continued in the search of effective vaccines or drug compounds against SARS-CoV-2 and a total of 64 vaccines are currently in clinical trials with 12 currently approved for use by different regulatory bodies, depending on the country. Since the outbreak of SARS-CoV-2, many countries have utilised traditional herbal medicines alongside conventional drugs for the treatment of infected patients. In this review, traditional medicines used to prevent or treat SARS-CoV-2 infection are listed along with the plant parts as used by the traditional healers. Additionally, the possible mechanisms responsible for this preventive or therapeutic outcome are also identified and listed. Our literature search was conducted using Google Scholar, PubMed, Scopus and WHO website. Unpublished reports such asdissertations and theses are not included. Plant parts including roots, leaves, flowers, seeds and so on have been used in the treatment of COVID-19. These traditional medicinal herbs may exert their anti-COVID-19 activity by direct inhibition of the virus replication or entry. Some may act by blocking the ACE-2 receptor, SARS-CoV helicase, Type II Transmembrane Serine Protease (TMPRSS2) and which are required by SARS-CoV-2 in order to infect human cells. Others act by inhibiting the SARSCoV-2 life-cycle related proteins, namely chymotrypsin-like cysteine protease (3CL-pro) and Papain-like protease (PL-pro). Medicinal plants are promising alternative medicines for the treatment or prevention of SARS-CoV-2 infection. Further researches, are needed to decipher their active components and structures which may suggest clues for the development of drugs against this novel coronavirus.

New Compounds

The use of plants with medicinal properties for fungi control has led to a continuous exploration of new compounds that could contribute towards promising studies in the development of new drugs and the knowledge of how this control is performed on microorganisms. The objective of this review has been to report on the potential use of medicinal plants to control the pathogenic fungi of a host of plants and animals, which can contribute to the achievement of new formulations for botanical fungicides. Many authors have demonstrated antifungal and general antimicrobial activities for Brazilian flora species through well-established methods, such as by microdilution, agar diffusion, and disk diffusion, while determining a minimum inhibitory concentration (MIC), minimum fungicidal concentrations (MFC), and the inhibition potential of essential oils, extracts and fractions. In this review, 68 species were cited for occurring in Brazil, with 25 being in the north-northeastern part of the country. Thus, most studies about the antimicrobial activities of medicinal plants bring an ‘initial understanding’ of their potential, particularly of some species, genera, and even families. Nevertheless, more data that is exceedingly specific is mandatory by focusing on new and more accurate approaches, such as the action mechanisms, toxicity, the active components, and the verification of the existence of synergic effects. These criteria would be the minimum required to develop new natural products as alternative treatments for the various infectious pathologies that affect plants, animals, and human beings.

Background:Worldwide, the progress in reducing neonatal mortality has been very slow. The rate of preterm birth has increased over the last 20 years in low-income and middle-income countries. Its association with increased mortality and morbidity is based on experimental studies and neonatal outcomes from countries with socioeconomic differences, which have considered implementing alternative healthcare strategies to prevent and reduce preterm births.Methods:Currently, there is no widely effective strategy to prevent preterm birth. Pharmacological therapies are directed at inhibiting myometrial contractions to prolong parturition. Some drugs, medicinal plants and microorganisms possess myorelaxant, anti-inflammatory and immunomodulatory properties that have proved useful in preventing preterm birth associated with inflammation and infection.Results:This review focuses on the existing literature regarding the use of different drugs, medicinal plants, and microorganisms that show promising benefits for the prevention of preterm birth associated with inflammation and infection. New alternative strategies involving the use of PDE-4 inhibitors, medicinal plants and probiotics could have a great impact on improving prenatal and neonatal outcomes and give babies the best start in life, ensuring lifelong health benefits.Conclusion:Despite promising results from well-documented cases, only a small number of these alternative strategies have been studied in clinical trials. The development of new drugs and the use of medicinal plants and probiotics for the treatment and/or prevention of preterm birth is an area of growing interest due to their potential therapeutic benefits in the field of gynecology and obstetrics.

Metabolic syndrome is a collective term that denotes disorder in metabolism, symptoms of which include hyperglycemia, hyperlipidemia, hypertension, and endothelial dysfunction. Diet is a major predisposing factor in the development of metabolic syndrome, and dietary intervention is necessary for both prevention and management. The bioactive constituents of food play a key role in this process. Micronutrients such as vitamins, carotenoids, amino acids, flavonoids, minerals, and aromatic pigment molecules found in fruits, vegetables, spices, and condiments are known to have beneficial effects in preventing and managing metabolic syndrome. There exists a well-established relationship between oxidative stress and major pathological conditions such as inflammation, metabolic syndrome, and cancer. Consequently, dietary antioxidants are implicated in the remediation of these complications. The mechanism of action and targets of dietary antioxidants as well as their effects on related pathways are being extensively studied and elucidated in recent times. This review attempts a comprehensive study of the role of dietary carotenoids in alleviating metabolic syndromewith an emphasis on molecular mechanism-in the light of recent advances.

Background: Thymol is a natural phenolic monoterpenoid widely used in pharmaceutical and food preservative applications. Thymol isomeric with carvacrol, extracted primarily from Thymus species (Trachyspermum ammi) and other plants sources such as Baccharisgrise bachii and Centipeda minima, has ethnopharmacological characteristics. <p></p> Methods: This review was prepared by analyzing articles published on thymol moiety in last decade and selected from Science Direct, Scopus, Pub Med, Web of Science and SciFinder. The selected articles are classified and gives brief introduction about thymol and its isolation, illustrates its natural as well as synthetic sources, and also therapeutic benefits of thymol worldwide <p></p> Results: Thymol has been covering different endeavors such as antimicrobial, antioxidant, antiinflammatory, antibacterial, antifungal, antidiarrhoeal, anthelmintic, analgesic, digestive, abortifacient, antihypertensive, spermicidal, depigmenting, antileishmanial, anticholinesterase, insecticidal and many others. This phenolic compound is among the essential scaffolds for medicinal chemists to synthesize more bio-active molecules by further derivatization of the thymol moiety. <p></p> Conclusion: Thymol is an interesting scaffold due to its different activities and derivatization of thymol is proved to enhance its biological activities. However, more robust, randomised, controlled clinical trials would be desirable with well-characterised thymol preparations to corroborate its beneficial effects in diseased patients. Moreover, in view of the potential use of thymol and thymol-rich essential oils in the treatment of human infections, comprehensive studies on chronic and acute toxicity and also teratogenicity are to be recommended.
