Chemical and Biological Evaluation of Amazonian Medicinal Plant Vouacapoua americana Aubl. PLANTS (BASEL, SWITZERLAND) 2022; 12:99.

Abstract
Vouacapoua americana (Fabaceae) is an economically important tree in the Amazon region and used for its highly resistant heartwood as well as for medicinal purposes. Despite its frequent use, phytochemical investigations have been limited and rather focused on ecological properties than on its pharmacological potential. In this study, we investigated the phytochemistry and bioactivity of V. americana stem bark extract and its constituents to identify eventual lead structures for further drug development. Applying hydrodistillation and subsequent GC-MS analysis, we investigated the composition of the essential oil and identified the 15 most abundant components. Moreover, the diterpenoids deacetylchagresnone (1), cassa-13(14),15-dien-oic acid (2), isoneocaesalpin H (3), (+)-vouacapenic acid (4), and (+)-methyl vouacapenate (5) were isolated from the stem bark, with compounds 2 and 4 showing pronounced effects on Methicillin-resistant Staphylococcus aureus and Enterococcus faecium, respectively. During the structure elucidation of deacetylchagresnone (1), which was isolated from a natural source for the first time, we detected inconsistencies regarding the configuration of the cyclopropane ring. Thus, the structure was revised for both deacetylchagresnone (1) and the previously isolated chagresnone. Following our works on Copaifera reticulata and Vatairea guianensis, the results of this study further contribute to the knowledge of Amazonian medicinal plants.

[PMID: 32172016 DOI: 10.1016/j.phytochem.2020.112343] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Revised: 01/17/2020] [Accepted: 03/05/2020] [Indexed: 06/10/2023]
Abstract
Detailed phytochemical investigation of the roots of Erythrophleum fordii furnished seven undescribed cassane-type diterpenoids, erythrocassanoids A-E and erythro-norcassanoids A, B and two known clerodane diterpenes, 15-hydroxy-3-cleroden-2-one and methyl ester of 2-oxopopulifolic acid. Their structures were determined by 1D, 2D NMR and HRESIMS analysis. The antiviral activities of these compounds were evaluated. Among them, 15-hydroxy-3-cleroden-2-one and methyl ester of 2-oxopopulifolic acid showed antiviral activities against influenza virus and coxsackie virus with IC50 values ranging from 11.11 to 29.60 μM.

Abstract
As therapeutic tools, diterpenes and their derivatives have gained much attention of the medicinal scientists nowadays. It is due to their pledging and important biological activities. This review congregates the anticancer diterpenes. For this, a search was made with selected keywords in PubMed, Science Direct, Web of Science, Scopus, The American Chemical Society and miscellaneous databases from January 2012 to January 2017 for the published articles. A total 28, 789 published articles were seen. Among them, 240 were included in this study. More than 250 important anticancer diterpenes and their derivatives were seen in the databases, acting in the different pathways. Some of them are already under clinical trials, while others are in the nonclinical and/or pre-clinical trials. In conclusion, diterpenes may be one of the lead molecules in the treatment of cancer.
