    A Pharmacological Perspective on Plant?derived Bioactive Molecules for Epilepsy
    (Springer, 2021) Sharifi-Rad, Javad; Quispe, Cristina; Herrera-Bravo, Jesus; Martorell, Miquel; Sharopov, Farukh; Boyuneğmez Tümer, Tuğba; Kurt, Begüm; Lankatillake, Chintha; Docea, Anca Oana; Moreira, Ana Catarina; Dias, Daniel A.; Mahomoodally, Mohamad Fawzi; Lobine, Devina; Cruz-Martins, Natalia; Kumar, Manoj; Calina, Daniela
    Epilepsy is a related chronic neurological condition of a predisposition for recurrent epileptic seizures, with various manifestations and causes. Although there are antiepileptic drugs, complementary natural therapies are widely used. The purpose of this systematic review was to analyze the antiepileptic/anticonvulsant pharmacological properties of plant-food derived bioactive molecules. In this regard, a systematic review of the PubMed database was made based on the inclusion criteria. Natural compounds/herbs with scientifcally proven antiepileptic properties were selected. Experimental pharmacological studies in vitro and in vivo have shown that favonoids, alkaloids and terpenoids may have anticonvulsant mechanisms similar to the new generation antiepileptic drugs. The relationships of structure-anticonvulsant efect, pharmacological models, seizure-inducing factors and response, efective dose were also analyzed and discussed. The results of in vitro and in vivo pharmacological studies analyzed in this systematic review support the clinical importance of plant-food-derived bioactive molecules for the complementary treatment of epilepsy. Thus, are opened new perspectives to develop new natural anticonvulsant drugs.

    Impact of Natural Compounds on Neurodegenerative Disorders: From Preclinical to Pharmacotherapeutics
    (Mdpi, 2020) Sharifi-Rad, Mehdi; Lankatillake, Chintha; Dias, Daniel A.; Docea, Anca Oana; Mahomoodally, Mohamad Fawzi; Lobine, Devina; Chazot, Paul L.
    Among the major neurodegenerative disorders (NDDs), Alzheimer's disease (AD) and Parkinson's disease (PD), are a huge socioeconomic burden. Over many centuries, people have sought a cure for NDDs from the natural herbals. Many medicinal plants and their secondary metabolites are reported with the ability to alleviate the symptoms of NDDs. The major mechanisms identified, through which phytochemicals exert their neuroprotective effects and potential maintenance of neurological health in ageing, include antioxidant, anti-inflammatory, antithrombotic, antiapoptotic, acetylcholinesterase and monoamine oxidase inhibition and neurotrophic activities. This article reviews the mechanisms of action of some of the major herbal products with potential in the treatment of NDDs according to their molecular targets, as well as their regional sources (Asia, America and Africa). A number of studies demonstrated the beneficial properties of plant extracts or their bioactive compounds against NDDs. Herbal products may potentially offer new treatment options for patients with NDDs, which is a cheaper and culturally suitable alternative to conventional therapies for millions of people in the world with age-related NDDs.

    Insights on the Use of ?-Lipoic Acid for Therapeutic Purposes
    (Mdpi, 2019) Salehi, Bahare; Yilmaz, Yakup Berkay; Antika, Gizem; Tumer, Tugba Boyunegmez; Mahomoodally, Mohamad Fawzi; Lobine, Devina; Akram, Muhammad
    alpha-lipoic acid (ALA, thioctic acid) is an organosulfur component produced from plants, animals, and humans. It has various properties, among them great antioxidant potential and is widely used as a racemic drug for diabetic polyneuropathy-associated pain and paresthesia. Naturally, ALA is located in mitochondria, where it is used as a cofactor for pyruvate dehydrogenase (PDH) and alpha-ketoglutarate dehydrogenase complexes. Despite its various potentials, ALA therapeutic efficacy is relatively low due to its pharmacokinetic profile. Data suggests that ALA has a short half-life and bioavailability (about 30%) triggered by its hepatic degradation, reduced solubility as well as instability in the stomach. However, the use of various innovative formulations has greatly improved ALA bioavailability. The R enantiomer of ALA shows better pharmacokinetic parameters, including increased bioavailability as compared to its S enantiomer. Indeed, the use of amphiphilic matrices has capability to improve ALA bioavailability and intestinal absorption. Also, ALA's liquid formulations are associated with greater plasma concentration and bioavailability as compared to its solidified dosage form. Thus, improved formulations can increase both ALA absorption and bioavailability, leading to a raise in therapeutic efficacy. Interestingly, ALA bioavailability will be dependent on age, while no difference has been found for gender. The present review aims to provide an updated on studies from preclinical to clinical trials assessing ALA's usages in diabetic patients with neuropathy, obesity, central nervous system-related diseases and abnormalities in pregnancy.
