Mata-Torres G, Andrade-Cetto A, Espinoza-Hernández F. Approaches to Decrease Hyperglycemia by Targeting Impaired Hepatic Glucose Homeostasis Using Medicinal Plants. Front Pharmacol 2021; 12:809994.

Abstract
Liver plays a pivotal role in maintaining blood glucose levels through complex processes which involve the disposal, storage, and endogenous production of this carbohydrate. Insulin is the hormone responsible for regulating hepatic glucose production and glucose storage as glycogen, thus abnormalities in its function lead to hyperglycemia in obese or diabetic patients because of higher production rates and lower capacity to store glucose. In this context, two different but complementary therapeutic approaches can be highlighted to avoid the hyperglycemia generated by the hepatic insulin resistance: 1) enhancing insulin function by inhibiting the protein tyrosine phosphatase 1B, one of the main enzymes that disrupt the insulin signal, and 2) direct regulation of key enzymes involved in hepatic glucose production and glycogen synthesis/breakdown. It is recognized that medicinal plants are a valuable source of molecules with special properties and a wide range of scaffolds that can improve hepatic glucose metabolism. Some molecules, especially phenolic compounds and terpenoids, exhibit a powerful inhibitory capacity on protein tyrosine phosphatase 1B and decrease the expression or activity of the key enzymes involved in the gluconeogenic pathway, such as phosphoenolpyruvate carboxykinase or glucose 6-phosphatase. This review shed light on the progress made in the past 7 years in medicinal plants capable of improving hepatic glucose homeostasis through the two proposed approaches. We suggest that Coreopsis tinctoria, Lithocarpus polystachyus, and Panax ginseng can be good candidates for developing herbal medicines or phytomedicines that target inhibition of hepatic glucose output as they can modulate the activity of PTP-1B, the expression of gluconeogenic enzymes, and the glycogen content.

Appiah EK, Hashem S, Fatsi PSK, Tettey PA, Saito H, Omura M, Kawai K. Antibacterial activity of Mallotus japonicus (L.F.) Müller Argoviensis on growth of Aeromonas hydrophila, A. salmonicida, Edwardsiella tarda and Vibrio anguillarum. J Appl Microbiol 2021; 132:298-310. [PMID: 34192394 DOI: 10.1111/jam.15198] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2021] [Revised: 04/08/2021] [Accepted: 06/07/2021] [Indexed: 11/30/2022]
Abstract
AIMS The present study evaluated the antimicrobial activities of the medicinal plant Mallotus japonicus against the fish pathogenic bacteria, Aeromonas hydrophila, Aeromonas salmonicida, Edwardisella tarda and Vibrio anguillarum, and also describes the antimicrobial activities of the major and minor active compounds present within the plant extract. The synergistic effects by way of combination of these compounds were also evaluated and described. Chemical constituents of the plant extracts were analysed using the liquid chromatography-mass spectrometry (LC-MS) and described. METHODS AND RESULTS The diethyl ether-extract of the plant elicited the strongest antibacterial activity against the challenged bacterial species, followed by ethanol- and methanol-extracts. The major active compound of the extracts, bergenin, demonstrated no antibacterial activity, but other compounds in the extracts did. CONCLUSION Mallotus japonicus could be used as a prophylaxis to treat bacterial disease infections of fishes and its diethyl ether-extract has the potential of an alternative to antibiotic treatment in aquaculture. SIGNIFICANCE AND IMPACT OF THE STUDY Mallotus japonicus diethyl ether-extract has the potential of an alternative to antibiotic treatment in aquaculture.

Protein tyrosine phosphatase 1B inhibitors from natural sources. Arch Pharm Res 2017; 41:130-161. [PMID: 29214599 DOI: 10.1007/s12272-017-0997-8] [Citation(s) in RCA: 45] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2017] [Accepted: 11/26/2017] [Indexed: 01/25/2023]
Abstract
Since PTP1B enzyme was discovered in 1988, it has captured the research community's attention. This landmark discovery has stimulated numerous research studies on a variety of human diseases, including cancer, inflammation, and diabetes. Tremendous progress has been made in finding PTP1B inhibitors and exploring PTP1B regulatory mechanisms. This review investigates for the natural PTP1B inhibitors, and focuses on the common characteristics of the discovered structures and structure-activity relationships. To facilitate understanding, all the natural compounds are here divided into five different classes (fatty acids, phenolics, terpenoids, steroids, and alkaloids), according to their skeletons. These PTP1B inhibitors of scaffold structures could serve as a theoretical basis for new concept drug discovery and design.

Abstract
Plants belonging to Melaleuca genus (Myrtaceae family) are native to Oceania, where they have been used for ages by Aborigine people in Australian traditional medicine, mainly because of their broad-spectrum antimicrobial activity. Although, M. linariifolia, M. dissitiflora, and other species of Melaleuca can also be used, the tea tree oil, an essential oil obtained from M. alternifolia shows the longest history of medicinal uses. Tea tree oil contains for the 80-90% several monoterpenes (terpinen-4-ol, α-terpinene, 1,8-cineol, p-cymene, α-terpineol, α-pinene, terpinolene, limonene, and sabinene). Sesquiterpenes and aromatic compounds further compose this oil. The essential oil of Melaleuca spp. has been reported to possess effective antibacterial and antifungal properties in vitro. In particular, data show that 1,8-cineol, terpinen-4-ol and methyl eugenol play the key role in mediating this oil's antimicrobial activity. Copyright © 2017 John Wiley & Sons, Ltd.
