Abstract
Six new polyoxygenated terpenoids, podovirosanes A-F (1-6), and two known polyketides (7 and 8) were isolated from the roots of F. virosa. Their structures, along with absolute configurations, were deduced using spectroscopic analysis as well as computational calculations, including TDDFT calculation of ECD spectra and GIAO NMR calculations combined with DP4+ probability analysis. Compounds 2, 3, 5, and 8 were found to reduce the phosphorylation levels of NF-κB p65 in SARS-CoV-2 pseudovirus-stimulated PMA-differentiated THP-1 cells.

[PMID: 35636565 DOI: 10.1016/j.phytochem.2022.113255] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Revised: 05/20/2022] [Accepted: 05/22/2022] [Indexed: 06/15/2023]
Abstract
Seven undescribed abietane-type diterpenoids, gauleucins A-G, and 11 known ones were isolated from an EtOH extract of the aerial parts of Gaultheria leucocarpa var. yunnanensis. These isolates could be classified into four subtypes: abietanes, 16-nor-abietanes, 16,18-di-nor-abietanes, and 3,4-seco-16-nor-abietane. Their structures were established by extensive spectroscopic analysis, and the absolute configurations of an undescribed and two known diterpenoids were determined by single-crystal X-ray diffraction data. Four compounds showed moderate inhibitory effects against the LPS-induced production of nitric oxide in BV-2 microglial cells. In an α-glucosidase inhibitory assay, gauleucin E and margoclin displayed inhibitory activities with IC50 values of 319.3 and 327.9 μM, respectively, while the IC50 value of the positive control (acarbose) was 387.8 μM.

Bioorg Chem 2022; 122:105720.

Abstract
The ethyl acetate extract of the stems of Jatropha curcas (ESJ) exerted prominent anti-neuroinflammatory effect through inhibiting microglial overactivation, and reducing mRNA expression of inflammatory factors, including nitric oxide (NO), inducible nitric oxide synthase, and interleukin-1β in the cortex and the formation of NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasomes in C57BL/6 mice. Phytochemical research afforded twenty-three major constituents, including five undescribed components (diterpenes 1-3, 7 and a triterpene 18) and a new natural product [a diterpene, (3S,5S,10R)-3-hydroxy-12-methoxy-13-methylpodopcarpa-8,11,13-trien-7-one (8)], by comprehensive analysis of spectroscopic data. Bioassay showed that ESJ (IC50: 6.49 μg/mL), diterpenes 1, 5, 12, 14, 15, 17, triterpenes 18, 19, preussomerin 22, and lactone 23 (IC50 values from 0.10 to 49.05 μM) inhibited NO production more strongly than the positive control in lipopolysaccharide-stimulated BV-2 cells. HPLC experiment further substantiated that 1, 5, 12, 14-15, 17-19, 22-23 are the characteristic constituents of ESJ, suggesting they might possess the potential for the treatment of neuroinflammation.

Abstract
Viral infections are among the most complex medical problems and have been a major threat to the economy and global health. Several epidemics and pandemics have occurred due to viruses, which has led to a significant increase in mortality and morbidity rates. Natural products have always been an inspiration and source for new drug development because of their various uses. Among all-natural sources, plant sources are the most dominant for the discovery of new therapeutic agents due to their chemical and structural diversity. Despite the traditional use and potential source for drug development, natural products have gained little attention from large pharmaceutical industries. Several plant extracts and isolated compounds have been extensively studied and explored for antiviral properties against different strains of viruses. In this review, we have compiled antiviral plant extracts and natural products isolated from plants reported since 2015.

Abstract
In an attempt to study the chemical constituents from the twigs and leaves of Flueggea virosa, a new terpenoid, 9(10→20)-abeo-ent-podocarpane, 3β,10α-dihydroxy-12-methoxy-13- methyl-9(10→20)-abeo-ent-podocarpa-6,8,11,13-tetraene (1), as well as five known compounds were characterized. Their structures were elucidated on the basis of spectroscopic analysis. In addition, the structure of dehydrochebulic acid trimethyl ester was revised as (2S,3R)-4E-dehydrochebulic acid trimethyl ester based on a single-crystal X-ray diffraction study. The in vitro anti-hepatitis C virus (anti-HCV) activity and cytotoxicity against Huh7.5 cells for the isolated compounds were evaluated.
