Abstract
One new dibenzocycloheptene, validinol (1), and one butanolide firstly isolated from the natural source, validinolide (2), together with 17 known compounds were isolated from the stem of Cinnamomum validinerve. Among the isolates, lincomolide A (3), secosubamolide (7), and cinnamtannin B1 (19) exhibited potent inhibition on both superoxide anion generation (IC50 values of 2.98 ± 0.3 µM, 4.37 ± 0.38 µM, and 2.20 ± 0.3 µM, respectively) and elastase release (IC50 values of 3.96 ± 0.31 µM, 3.04 ± 0.23 µM, and 4.64 ± 0.71 µM, respectively) by human neutrophils. In addition, isophilippinolide A (6), secosubamolide (7), and cinnamtannin B1 (19) showed bacteriostatic effects against Propionibacterium acnes in in vitro study, with minimal inhibitory concentration (MIC) values at 16 μg/mL, 16 μg/mL, and 500 μg/mL, respectively. Further investigations using the in vivo ear P. acnes infection model showed that the intraperitoneal administration of the major component cinnamtannin B1 (19) reduced immune cell infiltration and pro-inflammatory cytokines TNF-α and IL-6 at the infection sites. The results demonstrated the potential of cinnamtannin B1 (19) for acne therapy. In summary, these results demonstrated the anti-inflammatory potentials of Formosan C. validinerve during bacterial infections.

Abstract
Extracts from the roots of Paullinia pinnata L. are used in West Africa as traditional remedies for a variety of diseases including infestations with soil-transmitted helminths. Based on the results of an ethnopharmacological survey in Ghana, an aqueous acetone (70%) extract was investigated for its anthelmintic and phytochemical properties. Partitioning of the crude extract followed by several fractionation steps of the ethyl acetate phase using Sephadex® LH-20, fast centrifugal partition chromatography, RP-18-MPLC and HPLC led to isolation of six oligomeric A-type procyanidins (1 to 6). To determine the anthelmintic activity, the crude extract, fractions and isolated compounds were tested in vitro against the model organism Caenorhabditis elegans. A significantly better activity was observed for the trimeric A-type procyanidin (1) compared to a B-type trimer. However, this effect could not be generalized for the tetrameric procyanidins, for which the type of the interflavan-linkage (4→6 vs. 4→8) had the greatest impact on the bioactivity. Besides the procyanidins, three novel compounds, isofraxidin-7-O-α-l-rhamnopyranosyl-(1″→6')-β-d-glucopyranoside (17), 4-methoxycatechol-2-O-(5''-O-vanilloyl-β-apiofuranosyl)-(1''→2')-β-glucopyranoside (18) and a 6-(3-methoxy-4-hydroxyphenyl)-hexane-2,4-diol-2-O-hexoside (19) were isolated together with further ten known compounds (7 to 16), mainly coumarins and coumarinolignans. Except for 3-β-d-glucopyranosyloxy-4-methyl-2(5H)-furanone (15), none of the isolated compounds has previously been described for P. pinnata. The anthelmintic activity was attributed to the presence of procyanidins, but not to any of the other compound classes. In summary, the findings rationalize the traditional use of P. pinnata root extracts as anthelmintic remedies.

Biochem Pharmacol 2019; 172:113741.

Abstract
Na+/K+-ATPase α1 was reported to directly interact with and recruit FGF2 (fibroblast growth factor 2), a vital cell signaling protein implicated in angiogenesis, to the inner plasma membrane for subsequent secretion. Cardenolides, a class of cardiac glycosides, were reported to downregulate FGF2 secretion upon binding to Na+/K+-ATPase α1 in a cell system with ectopically expressed FGF2 and Na+/K+-ATPase α1. Herein, we disclose that the cardenolides ouabain and reevesioside A significantly enhance the secretion/release of FGF2 and the phosphorylation of FGFR1 (fibroblast growth factor receptor 1) in a time- and dose-dependent manner, in A549 carcinoma cells. A pharmacological approach was used to elucidate the pertinent upstream effectors. Only the ERK1/2 inhibitor U0126 but not the other inhibitors examined (including those inhibiting the unconventional secretion of FGF2) was able to reduce ouabain-induced FGF2 secretion and FGFR1 activation. ERK1/2 phosphorylation was increased upon ouabain treatment, a process found to be mediated through upstream effectors including ouabain-induced phosphorylated EGFR and a reduced MKP1 protein level. Therefore, at least two independent lines of upstream effectors are able to mediate ouabain-induced ERK1/2 phosphorylation and the subsequent FGF2 secretion and FGFR1 activation. These finding constitute unprecedent insights into the regulation of FGF2 secretion by cardenolides.

Abstract
Cardiac glycosides (CGs) are a class of naturally occurring steroid-like compounds, and members of this class have been in clinical use for more than 1500 years. They have been used in folk medicine as arrow poisons, abortifacients, heart tonics, emetics, and diuretics as well as in other applications. The major use of CGs today is based on their ability to inhibit the membrane-bound Na+/K+-ATPase enzyme, and they are regarded as an effective treatment for congestive heart failure (CHF), cardiac arrhythmia and atrial fibrillation. Furthermore, increasing evidence has indicated the potential cytotoxic effects of CGs against various types of cancer. In this review, we highlight some of the structural features of this class of natural products that are crucial for their efficacy, some methods of isolating these compounds from natural resources, and the structural elucidation tools that have been used. We also describe their physicochemical properties and several modern biotechnological approaches for preparing CGs that do not require plant sources.

Abstract
Coumarinolignans (CLs) are a group of non-conventional lignans having coumarins and phenyl propanes as two C6C3 units linked commonly through a dioxane bridge. The research findings during Jan 2008-May 2018 on this group of secondary metabolites describing their occurrence, structural characteristics, large-scale preparation, synthesis, derivatives, pharmacological activities, and structure-activity relationship are presented in this review. Around 38 CLs have been isolated from 40 plant species belonging to 20 different families during the review period. Reports on the syntheses of CL derivatives are also discussed. The majority of the reported CLs have shown potential anti-inflammatory activities, especially against pro-inflammatory cytokines. The other pharmacological effects exhibited by CLs such as hepatoprotective, anticancer, etc., are also covered in this review comprehending the lacunae in their development into drugs. This article is a continuation of our earlier work on coumarinolignans (Begum SA, Sahai M, Ray AB (2010) Non-conventional lignans: coumarinolignans, flavonolignans, and stilbenolignans. In: Kinghorn AD, Falk H, Kobayashi J (eds) Progress in the chemistry of organic natural products, Springer, Verlag/Wien, p 1-70).

Abstract
Seven new α,β-diphenyl-γ-butyrolactones (1-7), three new lignans (8-10), five new neolignans (11-15), two new 1,3-biphenylpropanoids (16 and 17), and a new flavonol galactoside-lignan ester (18), together with 43 known compounds (19-61), were isolated from the twigs of Cinnamomum cassia. Their structures were elucidated by spectroscopic data analysis as well as chemical methods. The α,β-diphenyl-γ-butyrolactones are a class of unique natural compounds that have only been isolated from C. cassia. Compounds 11 and 12 are rare examples of neolignans possessing a 1,2-dioxetane moiety. Compound 13 is a new oxyneolignan possessing a unique C-9-O-C-9' linkage between the benzopyran and cinnamyl alcohol moieties. Compound 15 is the first example of a natural neolignan possessing a 2-styryl-3-phenyltetrahydrofuran skeleton. The isolated compounds were evaluated for their neuroprotective activities against tunicamycin-induced cytotoxicity in SH-SY5Y cells. Compounds 3, 5, 10, 11, 12, 20, 36, and 56 showed statistically significant neuroprotective activity with EC50 values ranging between 21 and 75 μM.

Abstract
Six new polyoxygenated steroids (1-6) along with clathriol (7) were isolated from the Korean marine sponge Clathria gombawuiensis. Based upon the results of combined spectroscopic analyses, the structures of gombasterols A-F (1-6) were elucidated to be those of highly oxygenated steroids possessing a 3β,4α,6α,7β-tetrahydroxy or equivalent (7β-sodium O-sulfonato for 3) substitution pattern and a C-15 keto group as common structural motifs. The relative and absolute configurations of these steroids, including the rare 14β configuration of 1-4, were determined by a combination of NOESY, J-based analyses, the 2-methoxy-2-(trifluoromethyl)phenylacetic acid (MTPA) method, and X-ray crystallographic analysis. The absolute configuration of 7 was also assigned by these methods. These compounds moderately enhanced 2-deoxy-2-[(7-nitro-2,1,3-benzoxadiazol-4-yl)amino]-d-glucose (2-NBDG) uptake in differentiated 3T3-L1 adipocytes and phosphorylation of AMP-activated protein kinase (AMPK) and acetyl-CoA carboxylase (ACC) in differentiated mouse C2C12 skeletal myoblasts.
