Ethnopharmacological analysis based on Thai traditional medicine theory and anti-inflammatory activity of Sa-Tri-Lhung-Klod remedy as a post-partum anti-inflammatory drug. JOURNAL OF ETHNOPHARMACOLOGY 2024; 319:117207. [PMID: 37739101 DOI: 10.1016/j.jep.2023.117207] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 09/11/2023] [Accepted: 09/19/2023] [Indexed: 09/24/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sa-Tri-Lhung-Klod (ST) remedy is a Thai traditional remedy used in obstetrics and gynecology to reduce inflammation and nourish the body post-partum. In Thai traditional medicine (TTM), there is a theory of formulating drugs based on the four elements and the tastes of herbs for use in treating diseases. AIMS OF STUDY To determine relationships between taste theory and pharmacological properties for the anti-inflammatory effect of ST remedy and its chemical constituent components. To evaluate anti-inflammatory activity and also investigate the HPLC fingerprint of ST extracts. MATERIALS AND METHODS ST remedy was extracted by maceration in 95% ethanol (STE) and decoction in distilled water (STW). ST extracts were evaluated for anti-inflammatory activity by nitric oxide inhibitory assay in RAW264.7 cells, carrageenan-induced rat paw edema, and prostaglandin E2 inhibitory assay in inflamed rat paw tissue. In addition, the chemical constituent fingerprints of ST extracts were examined using HPLC. RESULTS STE contained seven main chemical compounds, and STW demonstrated only one identifiable chemical compound. The STE and STW displayed potent NO inhibitory activity with an IC50 value of 20.59 ± 0.03 and 52.93 ± 0.90 μg/mL, respectively. Moreover, the STE and STW (at doses of 100 - 400 mg/kg) promoted significant inhibition of inflammation in carrageenan-induced paw edema in rats (20.81 - 38.25%). Additionally, the STE (200 - 400 mg/kg) and STW (100 - 400 mg/kg) significantly reduced PGE2 levels in inflamed rat paw tissue. CONCLUSION These findings suggest that the spicy, astringent, sweet, and fragrant taste of the ST remedy used to treat post-partum inflammation encompass constituents with potent anti-inflammatory activity. STE and STW possess anti-inflammatory properties and effectively inhibit the production of NO and PGE2. Results confirm the use of the ST remedy for treating inflammatory diseases in the post-partum period according to TTM knowledge.

Effects of Encapsulation of Caesalpinia sappan L. with Cyclodextrins for Bovine Mastitis. AAPS PharmSciTech 2023; 24:230. [PMID: 37964017 DOI: 10.1208/s12249-023-02687-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Accepted: 10/24/2023] [Indexed: 11/16/2023] Open
Abstract
The main components of Caesalpinia sappan L. (CS) are brazilin and brazilein, which show high potential in pharmacologic applications. However, these have been drastically limited by the poor water solubility and stability. The present study investigates the formation of inclusion complexes F1, F2, and F3 between CS and β-cyclodextrin (βCD), hydroxypropyl-β-cyclodextrin (HPβCD), and methyl-β-cyclodextrin (MβCD), respectively. These complexes were characterized by Fourier transform infrared spectroscopy (FT-IR). The results showed that the highest encapsulation efficiency and loading capacity of CS extract were 44.24% and 9.67%, respectively. The solubility and stability of CS extract were significantly increased through complexation in phase solubility and stability studies. The complexes F1-F3 showed mainly significant antibacterial activities on gram-positive bacteria pathogens causing mastitis. Moreover, the expression levels of COX-2 and iNOS were significantly decreased in LPS-induced inflammatory cells at concentrations of 50 and 100 µg/mL. In addition, treatment of complex F3 (CS/MβCD) in bovine endothelial cells remarkably increased the chemokine gene expression of CXCL3 and CXCL8, which were responsible for immune cell recruitment (9.92 to 11.17 and 8.23 to 9.51-fold relative to that of the LPS-treated group, respectively). This study provides a complete characterization of inclusion complexes between CS extract and βCD, HPβCD, and MβCD for the first time, highlighting the impact of complex formation on the pharmacologic activities of bovine mastitis.

Abstract
Homoisoflavone contains 16 carbon atoms in the skeleton. The homoisoflavonoid skeleton from natural products can be roughly divided into 13 kinds, among which 5 kinds of common skeletons contain a large amount of compounds and 8 kinds of abnormal skeletons comprise a small amount of compounds. In this article, the structure identification experience of homoisoflavonoids found in Caesalpinia mimosoides was used as references and an efficient 1H NMR spectroscopic method for identifying homoisoflavonoid structure has been established. Using the chemical shift differences of H-2, 3, 4 and 9, the common natural homoisoflavonoids can be quickly and conveniently determined.

Abstract
Microcrystalline cellulose (MCC) has gained considerable attention as a functional ingredient in bread making. This work demonstrates the isolation of MCC from sugar cane bagasse (SCB) for preparing bread. The effect of MCC on bread attributes and antioxidant activity by impregnation with sappan wood extract (SAP) was evaluated. The highest crystallinity index and suitable size of MCC were achieved at 85 °C under 90 min hydrolysis condition. Increasing MCC/SAP levels in bread showed a significant increase in bread color with decreases in the specific volume and baking loss. There was a positive correlation between bread texture and the MCC/SAP level. The addition of MCC/SAP interfered with the bread hardness. Low MCC/SAP levels have no effect on springiness and cohesiveness; however, 4% MCC/SAP has significantly decreased these attributes, with the highest antioxidant activity and phenolic content. Therefore, MCC can be functionalized with SAP as an antioxidant fiber additive for health benefits in bakery products.

Abstract
Five new diarylbutyrolactones and sesquilignans (1A/1B: - 4: ), including one pair of enantiomers (1A/1B: ), together with 10 known analogues (5: - 14: ), were isolated from the whole plants of Saussurea medusa. Compound 1: was found to possess an unusual 7,8'-diarylbutyrolactone lignan structure. Separation by chiral HPLC analysis led to the isolation of one pair of enantiomers, (+)-1A: and (-)-1B: . The structures of the new compounds were elucidated by extensive spectroscopic data. All compounds, except compounds 5, 7: and 9: , were isolated from S. medusa for the first time. Moreover, compounds 1: - 4, 8: and 10: - 14: had never been obtained from the genus Saussurea previously. Compounds (+)- 1A, 2, 5, 7: , and 9: - 11: were found to inhibit the lipopolysaccharide (LPS)-induced release of NO by RAW264.7 cells with IC50 values ranging from 10.1 ± 1.8 to 41.7 ± 2.1 µM. Molecular docking and iNOS expression experiments were performed to examine the interactions between the active compounds and the iNOS enzyme.

Abstract
Flavanones and their biochemical precursors, chalcones, are naturally occurring compounds and consist of privileged scaffolds used in drug discovery due to their wide range of biological activities. In this work, two novel flavanones (3 and 4), the arylidene flavanone 5, and the chalcone 6, displaying structural analogies with butylated hydroxytoluene (BHT), were synthesized via an aldol reaction. According to the antioxidant activity studies of the synthesized flavanones, the arylidene flavanone 5 was the most potent antioxidant (70.8% interaction with DPPH radical and 77.4% inhibition of lipid peroxidation). In addition, the ability of the synthesized compounds to bind with ctDNA was measured via UV-spectroscopy, revealing that chalcone 6 has the strongest interaction with DNA (Kb = 5.0 × 10−3 M−1), while molecular docking was exploited to simulate the compound-DNA complexes. In an effort to explore the conformational features of the novel synthetic flavanones (3 and 4), arylidene flavanone 5, and chalcone 6, theoretical calculations were applied and the calculation of their physicochemical properties was also performed.

Abstract
Three pairs of novel enantiomeric 8-O-4′ type neolignans (1a/1b−3a/3b), together with seven known analogues (4−10), were isolated from the whole plants of Saussurea medusa. Their structures were elucidated by extensive spectroscopic data analysis and electric circular dichroism (ECD) calculations after chiral separations. All compounds were obtained from S. medusa for the first time, and compounds 1−3 and 5−10 had never been obtained from the genus Saussurea previously. The anti-inflammatory activities of the compounds were evaluated by determining their inhibitory activities on the production of NO and inducible nitric oxide synthase (iNOS) expression in LPS-stimulated RAW 264.7 cells. Compounds (+)-1a, (−)-1b and 5−7 inhibited NO production and had IC50 values ranging from 14.3 ± 1.6 to 41.4 ± 3.1 μM. Compound 7 induced a dose-dependent reduction in the expression of iNOS in LPS-treated RAW 264.7 cells. Molecular docking experiments showed that all active compounds exhibited excellent docking scores (<−7.0 kcal/mol) with iNOS. Therefore, compounds (+)-1a, (−)-1b and 5−7 isolated from the whole plants of S. medusa may have therapeutic potential in inflammatory diseases.

[PMID: 34603037 PMCID: PMC8479160 DOI: 10.3389/fphar.2021.725745] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Accepted: 08/31/2021] [Indexed: 01/13/2023] Open
Abstract
Cardiovascular diseases are the leading cause of death worldwide. The long-term aim of cardiovascular disease therapy is to reduce the mortality rate and decelerate the progression of cardiovascular organ damage. Current therapies focus on recovering heart function and reducing risk factors such as hyperglycemia and dyslipidemia. However, oxidative stress and inflammation are important causes of further damage to cardiovascular organs. Caesalpinia sappan Linn. (Fabaceae), a flowering tree native to tropical Asia, has antioxidant and anti-inflammatory properties. It is used as a natural dye to color food and beverages and as a traditional treatment for diarrhea, diabetes, and blood stasis. The phytochemical compounds in C. sappan, mainly the homoisoflavonoids brazilin, sappanone A, protosappanin, and hematoxylin, can potentially be used to protect cardiovascular organs. This review aims to provide updates on recent developments in research on C. sappan in relation to treatment of cardiovascular diseases. Many studies have reported protective effects of the plant’s bioactive compounds that reduce cardiac damage and enhance vasorelaxation. For example, brazilin and sappanone A have an impact on molecular and cellular changes in cardiovascular disease pathogenesis, mainly by modulating oxidative, inflammatory, and apoptotic signaling pathways. Therefore, bioactive compounds of C. sappan have the potential to be developed as therapeutic agents to combat cardiovascular diseases like myocardial infarction and vascular disease. This review could help further the understanding of the possible modulatory role of the compounds in cardiovascular diseases, thereby facilitating future studies.

Abstract
The latest global outbreak of 2019 respiratory coronavirus disease (COVID-19) is triggered by the inception of novel coronavirus SARS-CoV2. If recent events are of any indicators of the epidemics of past, it is undeniable to state a fact that the SARS-CoV2 viral infection is highly transmissible with respect to its previously related SARS-CoV’s. Papain-like protease (PLpro) is an enzyme that is required by the virus itself for replicating into the host system; and it does so by processing its polyproteins into a functional replicase complex. PLpro is also known for downregulating the genes responsible for producing interferons, an essential family of molecules produced in response to viral infection, thus making this protein an indispensable drug target. In this study, PLpro inhibitors were identified through high throughput structure-based virtual screening approach from NPASS natural product library possessing ~ 35,000 compounds. Top five hits were scrutinised based on structural aromaticity and ability to interact with a key active site residue of PLpro, Tyr268. For second level of screening, the MM-GBSA End-Point Binding Free Energy Calculation of the docked complexes was performed, which identified Caesalpiniaphenol A as the best hit. Caesalpiniaphenol A not only possess a double ring aromatic moiety but also has lowest minimum binding energy, which is at par with the control GRL0617, the only known inhibitor of SARS-CoV2 PLpro. Details of the Molecular Dynamics (MD) simulation and ADMET analysis helped to conclusively determine Caesalpiniaphenol A as potentially an inhibitor of SARS-CoV2 PLpro.

Abstract
Two new xanthones delpyxanthone A (1) and delpyxanthone B (3), together with four known ones, gerontoxanthone I (2), α-mangostin (4), cowanin (5) and cowanol (6) were isolated from the stem bark of Garcinia delpyana. The chemical structures of 1-6 were established mainly using nuclear magnetic resonance (NMR) and mass spectrometry (MS). The anti-inflammatory activity of the isolated compounds was evaluated against lipopolysaccharide (LPS)-induced nitric oxide (NO) production in RAW264.7 cells in vitro. Compounds 1-4 showed significant inhibitory activity against the LPS-induced NO production in RAW264.7 cells with IC50 values ranging from 14.5 to 28.2 μM, but the others were inactive. The results suggested that G. delpyana and its constituents might be potential anti-inflammatory agents on RAW 264.7 cells.[Formula: see text].

JOURNAL OF ETHNOPHARMACOLOGY 2021; 268:113520. [PMID: 33129948 DOI: 10.1016/j.jep.2020.113520] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/25/2020] [Revised: 10/24/2020] [Accepted: 10/26/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Prasachandaeng (PSD) remedy is a famous antipyretic drug for adults and children in Thai traditional medicine used and is described in Thailand's National List of Essential Medicine. Relationship between the taste of this herbal medicine, ethnopharmacological used and its pharmacological properties was reviewed. AIMS OF STUDY Since there has been no scientific report on the antipyretic activity of PSD, aim of this study was to investigate the efficacy related antipyretic drug of the remedy and its 12 herbal ingredients. It involved quality evaluation of raw materials, extraction of PSD and its ingredients, in vitro evaluation of their inhibitory activities on fever mediators, i.e. NO and PGE2 production in murine macrophage (RAW 264.7) cell line stimulated by lipopolysaccharide, and its stability study of the 95% ethanolic extract of PSD remedy. MATERIALS AND METHODS PSD remedy was extracted by maceration with 50% and 95% ethanol (PSD50 and PSD95), by decoction with distilled water (PSDW), and hydrolysis of PSDW with 0.1 N HCl (PSDH). The 12 plant ingredients were extracted with 95% ethanol. Quality evaluation of PSD ingredients was performed according to the standard procedures for the quality control of herbal materials. The inhibitory activity on nitric oxide production was determined by the Griess reaction and the inhibition of prostaglandin E2 production was determined using the ELISA test kit. RESULTS PSD ingredients passed the quality standard stipulated for herbal materials. PSD95 exhibited the highest inhibitory activities on the production of NO and PGE2 with the IC50 values of 42.40 ± 0.72 and 4.65 ± 0.76 μg/mL, respectively. A standard drug acetaminophen (ACP) exhibited inhibition of NO and PGE2 production with the IC50 values of 99.50 ± 0.43 and 6.110 ± 0.661 μg/mL, respectively. The stability study was suggested two years shelf-life of PSD95. This is the first report on the activity related antipyretic activity of PSD remedy and its ingredients against two fever mediators, NO and PGE2. CONCLUSION The results suggested that the 95% ethanolic extracts of PSD remedy and some of its ingredients, were better than ACP in reducing fever. PSD should be further studied using in vivo models and clinical trials to support its use as an antipyretic drug in Thai traditional medicine.

Abstract
The incidence of myocardial infarction, among the causes of cardiovascular morbidity and mortality, is increasing globally. In this study, left ventricular (LV) dysfunction, including LV systolic and diastolic function, was investigated in a rat myocardial ischemia/reperfusion injury model with echocardiography. The homoisoflavanone sappanone A is known for its anti-inflammatory effects. Using echocardiography, we found that sappanone A administration significantly improved LV systolic and diastolic function in a rat myocardial ischemia/reperfusion injury model, especially in the early phase development of myocardial infarction. Based on myocardial infarct size, serum cardiac marker assay, and histopathological evaluation, sappanone A showed higher efficacy at the doses used in our experiments than curcumin and was evaluated for its potential to improve LV function.

Anti-Inflammatory Compounds from Vietnamese Piper bavinum. J CHEM-NY 2020. [DOI: 10.1155/2020/1038636] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/17/2022] Open
Abstract
This study reports the anti-inflammatory activity-guided fractionation of the aerial part of Piper bavinum C. CD. (Piperaceae) that led to the isolation of eight secondary metabolites (1–8). The chemical structures of 1–8 were established mainly by NMR and mass spectra. Compound 5 was isolated from P. bavinum for the first time. All the isolated compounds were evaluated against LPS-induced NO production in macrophage RAW 264.7 cells in vitro. Among them, compound 4 showed the most potent inhibitory activity against the LPS-induced NO production with an IC50 value of 5.2 μM followed by compound 5 that inhibited NO production with an IC50 value of 13.5 μM. In the protein levels, compound 4 suppressed LPS-induced COX-2 and iNOS expressions in a dose-dependent manner. The results suggested that P. bavinum and its constituents might exert anti-inflammatory effects.

Abstract
Two new compounds, namely, arteordosin A (1) and arteordosin B (2), were isolated from the CHCl3 extract of Artemisia ordosica. This is the first report on the structure elucidation of arteordosin A (1) and arteordosin B (2) based on spectroscopic methods including electrospray ionization mass spectrometry, one-dimensional (1D) nuclear magnetic resonance spectroscopy (NMR) and 2D NMR techniques. Antioxidant activities of the compounds were measured for their radical scavenging capacity using 2,2-diphenyl-1-picrylhydrazyl. Compound 1 (IC50 of 1.01 mg mL−1) showed antioxidant activity similar to the standard reference ascorbic acid (IC50 of 0.98 mg mL−1) and is more active than compound 2 (IC50 of 1.87 mg mL−1). In conclusion, arteordosin A (1) and arteordosin B (2) may be used as potential antihyperlipidemic agent in routine clinical practice.

Abstract
This review documents all the new homoisoflavonoids (HIFs) that have been reported since 2007, whose total number has grown from 159 in 2007 to 295 at the present time. This review contains their structures, biological sources, plant parts they are obtained from, and, if reported, their optical rotations and melting points. The same classification is followed as an earlier review to ease reference to both reviews. This review takes note of the recent revision of plant families that were known to contain HIFs that have now been merged into one big family, Asparagaceae. Homoisoflavonoids also occur in Fabaceae and others. Two taxa, Ophiopogoan japonicus (Asparagaceae) and Caesalpinia sappan (Fabaceae), have been the source of many HIFs. These are briefly summarized. The biological properties of HIFs are also reviewed under the topics such as antioxidant, anti-inflammatory, antimicrobial, antidiabetic, and cytotoxic. The review also surveys the total synthesis of natural HIFs. All new compounds are classified and tabulated following the same style as the previous review. Dedicated to Professor Andrew Paul Krapcho on the occasion of his 87th Birthday.

Abstract
Protein disulfide isomerase (PDI) is responsible for nascent protein folding in the endoplasmic reticulum (ER) and is critical for glioblastoma survival. To improve the potency of lead PDI inhibitor BAP2 (( E)-3-(3-(4-hydroxyphenyl)-3-oxoprop-1-en-1-yl)benzonitrile), we designed and synthesized 67 analogues. We determined that PDI inhibition relied on the A ring hydroxyl group of the chalcone scaffold and cLogP increase in the sulfonamide chain improved potency. Docking studies revealed that BAP2 and analogues bind to His256 in the b' domain of PDI, and mutation of His256 to Ala abolishes BAP2 analogue activity. BAP2 and optimized analogue 59 have modest thiol reactivity; however, we propose that PDI inhibition by BAP2 analogues depends on the b' domain. Importantly, analogues inhibit glioblastoma cell growth, induce ER stress, increase expression of G2M checkpoint proteins, and reduce expression of DNA repair proteins. Cumulatively, our results support inhibition of PDI as a novel strategy to treat glioblastoma.

Protosappanin A exerts anti-neuroinflammatory effect by inhibiting JAK2-STAT3 pathway in lipopolysaccharide-induced BV2 microglia. Chin J Nat Med 2018; 15:674-679. [PMID: 28991528 DOI: 10.1016/s1875-5364(17)30096-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2016] [Indexed: 12/16/2022]
Abstract
Microglial activation and resultant neuroinflammatory response are implicated in various brain diseases including Alzheimer's disease and Parkinson's disease. Treatment with anti-neuroinflammatory agents could provide therapeutic benefits for such disorders. Protosappanin A (PTA) is a major bioactive ingredient isolated from Caesalpinia sappan L.. In this work, the anti-neuroinflammatory effects of PTA on LPS-stimulated BV2 cells were investigated and the underlying mechanisms were explored. Results showed that PTA significantly inhibited the production of TNF-α and IL-1β in LPS-activated BV2 microglia. Moreover, the mRNA expressions of IL-6, IL-1β, and MCP-1 were reduced by PTA in a dose-dependent manner. Furthermore, PTA suppressed JAK2/STAT3-dependent inflammation pathway through down-regulating the phosphorylation of JAK2 and STAT3, as well as STAT3 nuclear translocation against LPS treatment. These observations suggested a novel role for PTA in regulating LPS-induced neuroinflammatory injuries.

Abstract
Purpose: The aim of this study is to observe the synergistic effect of two active compounds of secang, brazilin and brazilein, combined with cisplatin on WiDr colon cancer cells. Methods: Cytotoxic activities of brazilin (Bi) and brazilein (Be) in single and in combination with cisplatin (Cisp) were examined by MTT assay. Synergistic effect was analyzed by combination index (CI) parameter. Apoptosis and cell cycle profiles were observed by using flow cytometry. Results: The result of MTT assay showed that IC50 value of brazilin and brazilein on WiDr cancer cells were 41 µM and 52 µM respectively. The combination of ½ IC50 of Bi-Cisp reduced cells viability up to 64% and showed synergistic effect with CI value less than 1 (CI = 0.8). The combinations of ½ IC50 of Be-Cisp also reduced cells viability up to 78% and showed synergistic effect (CI=0.65). Combination of Bi-Cisp and Be-Cisp induced apoptosis higher than the single treatments. Further analysis on the cell cycle progression showed that single treatment of ½ IC50 of Be and Bi induced S-phase and G2/M-phase accumulation, while combination of Be-Cisp and Bi-Cisp enhanced S-phase accumulation. Conclusion: Both combination of Bi-Cisp and Be-Cisp showed synergistic effect on WiDr cells through induction of apoptosis and halted the cell cycle progression, thus, WiDr cells growth were significantly reduced.

Abstract
Three pairs of new 8-O-4'-type dinorneolignan enantiomers, (±)-acortatarinowins A-C (1a/1b-3a/3b), a pair of new 8-O-4'-type (4a/4b) and a pair of rare C7-C8'-type (5a/5b) neolignan enantiomers, (±)-acortatarinowins D and E, and a pair of new furofuran-type lignan enantiomers, (±)-acortatarinowin F (6a/6b), along with two pairs of known lignan enantiomers (7a/7b and 8a/8b), were obtained from the rhizomes of Acorus tatarinowii. The separation of 1-8 by chiral HPLC using a Daicel IC column led to the isolation of eight pairs of enantiomers, 1a/1b-8a/8b, which had variable enantiomeric excess (ee) values of approximately 66, 71, 63, 60, 0, 38, 48, and 75%, respectively. The structures were elucidated by extensive spectroscopic and chemical methods, and their absolute configurations were determined by a combined analysis of single-crystal X-ray diffraction and a modified Mosher's method, assisted by experimental and calculated electronic circular dichroism data. Among them, compounds 1a, 3a, 6b, 8a, and 8b showed weak inhibitory activities against NO production in activated macrophages with IC50 values ranging from 23.3 to 38.0 μM, respectively.

Sappanone A exhibits anti-inflammatory effects via modulation of Nrf2 and NF-κB. Int Immunopharmacol 2015; 28:328-36.

Abstract
UNLABELLED Homoisoflavonoids constitute a small class of natural products. In the present study, we investigated the anti-inflammatory effect of sappanone A (SPNA), a homoisoflavanone that is isolated from the heartwood of Caesalpinia sappan (Leguminosae), in murine macrophages. SPNA inhibited the production of nitric oxide (NO), prostaglandin E2 (PGE2) and interleukin-6 (IL-6) as well as the expression of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2) and IL-6 in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. Moreover, SPNA protected C57BL/6 mice from LPS-induced mortality. Treatment of RAW264.7 cells with SPNA induced heme oxygenase (HO)-1 protein and mRNA expression and increased nuclear translocation of the nuclear factor-E2-related factor 2 (Nrf2) as well as the expression of Nrf2 target genes such as NAD(P)H quinone oxidoreductase 1 (NQO1). Knockdown of Nrf2 by siRNA blocked SPNA-mediated HO-1 induction. SB203580, p38 mitogen-activated protein kinase (MAPK) inhibitor, blocked SPNA-induced HO-1 expression and nuclear translocation of Nrf2, suggesting that SPNA induces HO-1 expression by activating Nrf2 through the p38 MAPK pathway. Consistent with the notion that the Nrf2/HO-1 pathway has anti-inflammatory properties, inhibiting HO-1 significantly abrogated the anti-inflammatory effects of SPNA in LPS-stimulated RAW264.7 cells. Moreover, SPNA suppressed LPS-induced nuclear factor κB (NF-κB) activation via inhibiting Ser 536 phosphorylation and transcriptional activity of RelA/p65 subunit of NF-κB. Taken together, these findings suggest that SPNA exerts its anti-inflammatory effect by modulating the Nrf2 and NF-κB pathways, and may be a valuable compound to prevent or treat inflammatory diseases.

Abstract
CONTEXT Caesalpinia sappan Linn. (Leguminosae) has been used in folk medicines for the treatment of many diseases. The heartwood of this plant contains various phenolic components with interesting biological applications; however, the chemical and biological potentials of the seed of this plant have not been fully explored. OBJECTIVE This study identified the cytotoxic activity of compounds from the seeds of C. sappan. MATERIALS AND METHODS The methanol extract of the seed of C. sappan was suspended in H2O and then partitioned with CH2Cl2, EtOAc, and n-BuOH, successively. Diterpenoid compounds were isolated from the CH2Cl2-soluble fraction by silica gel column chromatography methods using organic solvents. The compound structures were determined by detailed analysis of NMR and MS spectral data. Cytotoxic activity was measured using a modified MTT assay against HL-60, HeLa, MCF-7, and LLC cancer cells. The activation of caspase-3 enzyme and western blotting assay were performed to confirm inhibitory mechanism of active compound. RESULTS Five cassane-type diterpenoids were isolated and identified as phanginin I (1), phaginin A (2), phanginin D (3), phanginin H (4), and phanginin J (5). Compounds 1-4 showed effective inhibition against HL-60 cells with the IC50 values of 16.4 ± 1.5, 19.2 ± 2.0, 11.7 ± 1.6, and 22.5 ± 5.1 μM. Compounds 1-3 exhibited cytotoxic activity against HeLa cells with the IC50 values of 28.1 ± 3.6, 37.2 ± 3.4, and 22.7 ± 2.8 μM. Treatment of HL-60 cell lines with various concentrations of 3 (0-30 μM) resulted in the growth inhibition and induction of apoptosis. CONCLUSION These findings demonstrate that compound 3 (phanginin D) is one of the main active components of the seed of C. sappan activating caspases-3 which contribute to apoptotic cell death.

Abstract
Investigation of the South African plant Urginea depressa Baker (Asparagaceae Juss.) for antiproliferative activity against the A2780 ovarian cancer cell line led to the isolation of the six new homoisoflavonoids urgineanins A-F (1-6), the two known bufatrienolides 7 and 9, and the new bufatrienolides urginins B and C (8 and 10). Structures were elucidated based on analysis of their 1D and 2D NMR spectra, electronic circular dichroism, and mass spectrometric data. Five of the six new homoisoflavonoids had good antiproliferative activity against the A2780 ovarian cancer, A2058 melanoma, and H522-T1 human non-small-cell lung cancer cells, and urgineanin A (1) had submicromolar activity against all three cell lines. The four bufatrienolides 7-10 had strong antiproliferative activity against the same cell line, with IC50 values of 24.1, 11.2, 111, and 40.6 nM, respectively.
