NP MS Workflow: An Open-Source Software System to Empower Natural Product-Based Drug Discovery Using Untargeted Metabolomics.

Natural products (or specialized metabolites) are historically the main source of new drugs. However, the current drug discovery pipelines require miniaturization and speeds that are incompatible with traditional natural product research methods, especially in the early stages of the research. This article introduces the NP MS Workflow, a robust open-source software system for liquid chromatography-tandem mass spectrometry (LC-MS/MS) untargeted metabolomic data processing and analysis, designed to rank bioactive natural products directly from complex mixtures of compounds, such as bioactive biota samples.

evaluation of analgesic and anti-inflammatory activity of hydroalcoholic extracts from and their chemical composition by UPLC/MS analysis.

This study demonstrates analgesic and anti-inflammatory properties of hydroalcoholic extracts of leaves, bark and flowers from the (Bignoniaceae) plant, recognized as 'Ipê roxo' in Brazil. The extracts were evaluated in male Swiss albino mice via oral administration. Moreover, results of the paw oedema test induced by carrageenan revealed that extracts of leaves and bark displayed relevant anti-inflammatory activity potential at the dosage of 100 mg/kg, 300 mg/kg, and 500 mg/kg.

inhibition of PGE2 formation in human blood by four bicyclico [3.2.1] octane neolignans isolated from bark, two with unusual structural pattern.

The phytochemical investigation of the stem bark crude extract of (Lauraceae) led to the isolation of undescribed bicyclic [3.2.1] octane neolignans, and , characterized by unusual bicyclic patterns and two other known bicyclic neolignans and .

In vivo schistosomicidal activity of (±)-licarin A-loaded poly(ε-caprolactone) nanoparticles.

Schistosomiasis mansoni is an infectious parasitic disease caused by worms of the genus Schistosoma, and praziquantel (PZQ) is the medication available for the treatment of schistosomiasis. However, the existence of resistant strains reinforces the need to develop new schistosomicidal drugs safely and effectively. Thus, the (±)-licarin A neolignan incorporated into poly-Ɛ-caprolactone (PCL) nanoparticles and not incorporated were evaluated for their in vivo schistosomicidal activity.

A review on the anti-inflammatory activities of Brazilian green, brown and red propolis.

Humanity has used propolis since ancient times, and its use as a food supplement has significantly increased. Several reports on propolis´ biological activity and toxicity have highlighted its anti-inflammatory properties, unlike many natural food supplements. This review addresses the anti-inflammatory roles of Brazilian green, brown, and red propolis produced by Apis mellifera, their extracts, isolated compounds, and their mode of action.

Acetylcholinesterase and butyrylcholinesterase inhibition by nectriapyrone and tryptophol isolated from endophytic fungus sp.

Cholinesterase (ChE) inhibitors are currently the main drugs used to treat the cognitive symptoms of Alzheimer's disease (AD). Dual cholinesterase inhibitors, that is, compounds capable of inhibiting both acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE), are considered a new potential approach for the long-term treatment of patients with AD. We evaluated the ethyl acetate extract of sp.

Targeting Glycoproteins as a therapeutic strategy for diabetes mellitus and its complications.

Objectives: Glycoproteins are organic compounds formed from proteins and carbohydrates, which are found in many parts of the living systems including the cell membranes. Furthermore, impaired metabolism of glycoprotein components plays the main role in the pathogenesis of diabetes mellitus. The aim of this study is to investigate the influence of glycoprotein levels in the treatment of diabetes mellitus.

Water-Soluble Glutamic Acid Derivatives Produced in Culture by IS1-A from King George Island, Maritime Antarctica.

A new method of screening was developed to generate 770 organic and water-soluble fractions from extracts of nine species of marine sponges, from the growth media of 18 species of marine-derived fungi, and from the growth media of 13 species of endophytic fungi. The screening results indicated that water-soluble fractions displayed significant bioactivity in cytotoxic, antibiotic, anti-, anti-, and inhibition of proteasome assays. Purification of water-soluble fractions from the growth medium of IS1-A provided the new glutamic acid derivatives solitumine A (), solitumine B (), and solitumidines A-D (-).

Structure and Biogenesis of Roussoellatide, a Dichlorinated Polyketide from the Marine-Derived Fungus Roussoella sp. DLM33.

The structure of the fungal metabolite roussoellatide (1) has been established by spectroscopic and X-ray diffraction analyses. Results from feeding experiments with [1-(13)C]acetate, [2-(13)C]acetate, and [1,2-(13)C]acetate were consistent with a biosynthetic pathway to the unprecedented skeleton of 1 involving Favorskii rearrangements in separate pentaketides, subsequently joined via an intermolecular Diels-Alder reaction.

Acaricidal action of destruxins produced by a marine-derived Beauveria felina on the bovine tick Rhipicephalus (Boophilus) microplus.

The increasing resistance of Rhipicephalus (Boophilus) microplus tick to commercial insecticides requires alternative methods for the control of this cattle plague. The enthomopathogenic fungus Beauveria felina produces destruxins in culture media, cyclic depsipeptides which display an array of biological activities. The present investigation aimed to evaluate the acaricide action of destruxins isolated from B.
