Abstract
From the Lasianthus bidoupensis stems, two new compounds, including one new 9,10-anthraquinone, lasibidoupin A (1), and one new 6,7-benzocoumarin, lasibidoupin B (2), together with one known compound, 11-O-methyldamnacanthol (3) were isolated using chromatographic method. Their structures were determined by extensive HRMS, and NMR assignments. Compound 3 was reported for the first time from this species. New compounds (1 & 2) were tested for the cytotoxicity against three human cancer cell lines (MCF-7, HeLa, and NCI-H460) by SRB assay. As results, 1 & 2 exhibited significant cytotoxic activity against all cancer cell lines (IC50 ranged from 0.058 ± 0.003 to 0.177 ± 0.014 μM).

Abstract
In this study, a series of novel 3-seco-A derivatives of the natural triterpenes α-amyrin (1) and 3-epilupeol (2) were synthesized by a one-pot radical scission-oxidation procedure and evaluated in vitro and in vivo for their capacity to inhibit the inflammatory process. For the in vitro studies, the trans-4-hydroxy-l-proline methyl ester derivatives (1f and 2f) were consistently effective in inhibiting NO, IL-6, and TNF-α secretion, as well as inhibition of NF-κB activation, in RAW cells stimulated by LPS. The further in vivo anti-inflammatory study revealed that the trans-4-hydroxy-l-proline methyl ester derivatives (1f and 2f), together with 1g, were the most effective in inhibiting TPA-induced edema. Interestingly, the α-amyrin derivatives were the most potent inhibitors of COX-2, but inhibited COX-1 only to some extent. The hydroxyl derivative (1c) was selective for COX-2 inhibition (66.3 ± 1.1% at 17.5 μM) without affecting the COX-1 isoform and did not present toxicity. Molecular docking studies revealed that these compounds bind with their polar region in the cavity over Arg-120, and their lipophilic part is orientated to the HEM cofactor similarly to the natural substrate arachidonic acid in the catalytic site of COX-2. These results indicated that seco-A ursane derivatives could be considered promising candidates for the future development of selective NF-κB and COX-2 inhibitors.

Abstract
The anti-amyloidogenic potential and cyclooxygenase anti-inflammatory activity of Lasianthus trichophlebus extracts were evaluated. The MeOH extract (LTM) and chloroform extract (LTC) exhibited significant cytotoxic inhibition against the neuroblastoma SH-SY5Y cell with an IC50 of 17.52 μg/mL and 12.28 μg/mL, respectively. Thioflavin T assay indicated the LTC extract inhibition (70.56% at 50 μg/mL) to be statistically comparable (p < 0.05) to the positive control. Cyclooxygenase inhibition against COX-1 and COX-2 enzymes gave IC50 values for the LTM extract to be 18.20 and 29.60 µg/mL, respectively; while, the LTC extract showed 4.11 and 2.78 µg/mL, respectively. LC-MS of the LTM extract identified 22 putative compounds, which may prove to be pharmacologically relevant. This study has provided potential insights into the utilization of L. trichophlebus to develop safer plant-based agents for anti-inflammatory or neurodegenerative diseases.

Abstract
The genus Lasianthus (Rubiaceae) consists of approximately 180 species, of which the greatest species diversity is found in tropical Asia. Some of the Lasianthus species have been used in folk medicine to treat tinnitus, arthritis, fever, and bleeding. Lasianthus verticillatus (Lour.) Merr. (Syn. Lasianthus trichophlebus auct. non Hemsl.) is a shrub, branchlets terete about 1.5–3 m in height. This paper studies the chemical composition of the leaves of L. verticillatus for the first time, which resulted in the isolation of five undescribed iridoid glucosides, lasianosides A–E (1–5), together with three known compounds (6–8). The undescribed structures of isolated compounds (1–5) were characterized by physical and spectroscopic data analyses, including one-dimensional (1D) and two-dimensional (2D) NMR, IR, UV, and high-resolution electrospray ionization mass spectra (HR-ESI-MS). Furthermore, the electronic circular dichroism data determined the absolute configurations of the new compounds. The free radical scavenging properties of isolated compounds was assessed by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay, and their cytotoxicity was assessed toward human lung cancer cell line A549 by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method. Among the isolated compounds, 3 and 4 displayed potent radical scavenging activities with IC50 values of 30.2 ± 1.8 and 32.0 ± 1.2 µM, which were comparable to that of Trolox (29.2 ± 0.39 µM), respectively, while 5 possessed moderate activity with an IC50 value of 46.4 ± 2.3 µM. None of the isolated compounds exerted cytotoxicity against human cell line A549. As a result, lasianosides C, D, and E have the potential to be non-toxic safe antioxidant agents.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Careya arborea Roxb. (Lecythidaceae) is a large tree found throughout India in deciduous forests and grasslands. C. arborea is traditionally used in tumors, inflammation, anthelmintic, bronchitis, epileptic fits, astringents, antidote to snake-venom, skin disease, diarrhea, dysentery with bloody stools, dyspepsia, ulcer, tooth ache, and ear pain. AIM OF THE STUDY In our previous work, the methanolic extract of Careya arborea stem bark showed significant anti-inflammatory activity. As a continuity of that work, this study aimed at the isolation and evaluation of the anti-inflammatory effect of coumaroyl lupendioic acid, a new lupane-type triterpene from Careya arborea stem bark. Further, to give an insight into the underlying mechanism of action of the compound on the modulation of proinflammatory mediators. MATERIALS AND METHODS Methanolic extract of Careya arborea stem bark was suspended in water, and sequentially fractionated with n-hexane and ethyl acetate. Further ethyl acetate fraction was subjected to medium pressure liquid chromatography (MPLC) to isolate the active molecules. The isolated compounds were characterized by the various spectral techniques namely UV, IR, 1H NMR, 13C NMR, DEPT, 1H-1H COSY, HMBC and Mass spectral techniques. In vitro COX-1 and COX-2 enzyme inhibition assays using human whole blood was performed to investigate the inhibitory effect of the isolated compounds. The resulted potent COX-2 inhibitor of the isolated constituents compound 5, designated as coumaroyl lupendioic acid (CLA), was investigated in carrageenan induced inflammation and its effect was also compared with betulinic acid (BA) at the doses of 10 and 20mgkg-1, p.o. using indomethacin and celecoxib (10 and 20mgkg-1, p.o., respectively) as reference drugs. The effect of CLA on the production of NO, MPO, PGE2, TNF-α, IL-1β and IL-6 were assessed. In addition, the histopathology and immunohistochemistry (NF-ҡB, COX-2 and TNF-α protein expression) in paw tissues were also carried out. RESULTS The chromatographic fractionation of the methanolic extract resulted in isolation of six new derivatives of lupane type triterpenes for the first time from the stem bark of C. arborea; 3β-hydroxy-lup-5,20 (29),21-trien-28-oic acid (Compound 1), 1, 3, 13, 16-tetrahydroxy-lup-9(11), 20(29)-diene-28-oic acid (Compound 2), 1, 7-di hydroxy betulinic acid (Compound 3), 3β-O-dihydrocinnamyl betulinic acid (Compound 4), 3β-O-trans-coumaryl-lup-6, 9(11), 20(29)-triene-27, 28-dioic acid (Compound 5), 16β-hydroxy-2, 3-seco-lup-5, 20(29)-dien-2, 3, 28-trioic acid (Compound 6). Among the all isolated compounds 3β-O-trans-coumaryl-lup-6, 9(11), 20(29)-triene-27, 28-olioic acid designated as coumaroyl lupendioic acid (CLA) showed higher COX-2 selectivity which is comparable to reference drug (celecoxib). CLA significantly reduced carrageenan induced inflammation whereas CLA revealed greater effect as compared to BA at the similar corresponding doses. Moreover, CLA significantly inhibited pro-inflammatory mediators elevated by carrageenan. CLA also preserved the tissue architecture as evidenced by the histopathology. Furthermore, immunohistochemical studies revealed that CLA significantly down regulated NF-ҡB, COX-2 and TNF-α protein expression. CONCLUSION The study gives an insight into the molecular mechanisms of coumaroyl lupendioic acid and suggests that the down-regulations of proinflammatory mediators provide credence to the ethno botanical use of the plant in the management of inflammation.

Abstract
This study describes some characteristics of the Rubiaceae family pertaining to the occurrence and distribution of secondary metabolites in the main genera of this family. It reports the review of phytochemical studies addressing all species of Rubiaceae, published between 1990 and 2014. Iridoids, anthraquinones, triterpenes, indole alkaloids as well as other varying alkaloid subclasses, have shown to be the most common. These compounds have been mostly isolated from the genera Uncaria, Psychotria, Hedyotis, Ophiorrhiza and Morinda. The occurrence and distribution of iridoids, alkaloids and anthraquinones point out their chemotaxonomic correlation among tribes and subfamilies. From an evolutionary point of view, Rubioideae is the most ancient subfamily, followed by Ixoroideae and finally Cinchonoideae. The chemical biosynthetic pathway, which is not so specific in Rubioideae, can explain this and large amounts of both iridoids and indole alkaloids are produced. In Ixoroideae, the most active biosysthetic pathway is the one that produces iridoids; while in Cinchonoideae, it produces indole alkaloids together with other alkaloids. The chemical biosynthetic pathway now supports this botanical conclusion.

Two new lupane-type triterpenes, 24β-hydroxylupenone (1) and 3β-hydroxy-lup-20(29)-en-24-al (2), and two new ursane-type triterpenes, 28-formyloxy–3β-hydroxy-urs-12-ene (3) and 28-formyloxy-3β-acetoxy-urs-12-ene (4), together with 26 known triterpenes (5–30) were isolated from the leaves and trunk of Ilex cornuta Lindl. The structures of the new compounds were determined by spectroscopic methods, including 1D, 2D NMR (COSY, HMQC, HMBC, and NOESY), and HRMS data.

Abstract
Medicinal plants are becoming an important research area for novel and bioactive molecules for drug discovery. Novel therapeutic strategies and agents are urgently needed to treat different incurable diseases. Many plant derived active compounds are in human clinical trials. Currently ursolic acid is in human clinical trial for treating cancer, tumor, and skin wrinkles. This review includes the clinical use of ursolic acid in various diseases including anticancer, antitumor, and antiwrinkle chemotherapies, and the isolation and purification of this tritepernoid from various plants to update current knowledge on the rapid analysis of ursolic acid by using analytical methods. In addition, the chemical modifications of ursolic acid to make more effective and water soluble derivatives, previous and current information regarding, its natural and semisynthetic analogs, focusing on its anticancer, cytotoxic, antitumor, antioxidant, anti-inflammatory, anti-HIV, acetyl cholinesterase, α-glucosidase, antimicrobial, and hepatoprotective activities, briefly discussion is attempted here for its research perspectives. This review article contains fourteen medicinally important ursolic acid derivatives and 351 references.

Abstract
Seven new lupane triterpenoids were isolated from bioactive methanol extracts of Microtropis fokienensis (1- 4) and Perrottetia arisanensis (4-7), along with 18 known compounds. The structures of the new compounds were elucidated on the basis of spectroscopic data analysis. All triterpenoids were evaluated for their in vitro cytotoxicity toward seven human cancer cell lines. Compound 8 (28-hydroxy-3-oxo-lup-20(29)-en-30-al) was among the most cytotoxic substances obtained and was found to induce apoptosis of human leukemia HL60 cells and mediate cleavage of PARP and up-regulation of Bax proteins.
