Abstract
Waltherione A (1), a unique quinolone alkaloid fused with oxabicyclo[3.2.1]octane, was isolated originally from Waltheria douradinha and recently by us from a methanol extract of Melochia umbellata along with the related 3,4-dimethoxyquinoline paliasanines A-E. Compound 1 showed selective cytotoxicity against A549 and MCF-7 cell lines. Its interesting structural and biological features prompted several attempts at total synthesis and clarification of the absolute configuration, although none were successful to date. Now, we have accomplished the first total synthesis of 1 starting from commercially available benzosuberone in 21 steps as well as elucidated its absolute configuration.

Abstract
Five new quinoline alkaloids, paliasanines A-E (1-5), and 17 known compounds (6-22) were isolated from a methanol extract of Melochia umbellata var. deglabrata leaves. Their chemical structures were elucidated by analysis of HRMS and 1D and 2D NMR spectroscopic data. Compounds 1-5 are the first naturally occurring 3,4-methylenedioxyquinolines incorporating an oxabicyclo[3.2.1]octane unit. Compounds 6 and 7 displayed selective cytotoxicity (IC50 5.9-8.4 μM) against A549 and MCF-7 cell lines, while compounds 1-5 were not active. Compounds 1-3 did not exhibit an anti-HIV effect in MT4 cells, although the related quinolone derivative waltherione A exhibited significant activity. These preliminary results indicate that the 3-methoxy-4-quinolone skeleton might be preferred for both antiproliferative and anti-HIV activities.

Abstract
Heisteria parvifolia Sm. is prescribed in traditional medecine against numerous diseases in Côte d'Ivoire. Due to the shortcoming in scientifical knowledge of use of this species, our investigations revealed five undescribed cyclopeptide alkaloids added to one known derivative namely anorldianine. These compounds were elucidated by 1D and 2D-NMR experiments and comparison with literature data, and confirmed by HR-ESI-MS. Cytotoxic activity evaluation of these compounds against the chronic myeloid leukemia (K565) cell line exhibited an antiproliferative activity with cell growth inhibition from 13% to 46%.

Abstract
BACKGROUND Waltheria indica exhibited strong nematocidal activity against Meloidogyne incognita, a causal agent of root-knot nematode disease. This study aimed to characterize the nematocidal metabolites and to evaluate the efficacy of the formulated extract of W. indica in the biological control of M. incognita under both pot and field conditions. RESULTS Three 4-quinolone alkaloids, 5'-methoxywaltherione A, waltherione A and waltherione C, were isolated and characterized as nematocidal metabolites. 5'-Methoxywaltherione A and waltherione A caused high mortality in juveniles of Meloidogyne arenaria, Meloidogyne hapla, M. incognita and Bursaphelenchus xylophilus, whereas waltherione C exhibited significant nematocidal activity against only root-knot nematodes. In pot experiments, application of a wettable powder-type formulation of the ethyl acetate extract of W. indica (W. indica WP20) at 26.7, 53.4 and 106.8 mg a.i. kg-1 soil significantly reduced the formation of galls and egg masses on the roots of tomato plants in a dose-dependent manner. In addition, application of 20 mg a.i. per plant W. indica WP20 effectively reduced gall formation on the roots of melon plants and population density of nematode in soil compared with untreated control under field conditions. CONCLUSION W. indica can be used as an effective botanical nematicide in the eco-friendly control of root-knot nematode disease. © 2019 Society of Chemical Industry.

Abstract
Six extracts from the roots and the aerial parts of Waltheria indica L. (Malvaceae) were screened for their in vitro antitrypanosomal activity towards Trypanosoma brucei brucei STIB 427 strain, T. brucei rhodesiense STIB 900 and Trypanosoma cruzi Tulahuen C4. The dichloromethane extract from the roots showed the highest activity against T. cruzi (IC50=0.74 μg/mL) as well as a good selectivity index (SI value of 35). Based on these results, this extract was fractionated and led to the isolation of three alkaloids (adouetin X (1), waltheriones A (2) and C (3)) and three pentacyclic triterpene derivatives (betulinic acid (4), 3β-acetoxy-27-trans-caffeoyloxyolean-12-en-28-oic acid methyl ester (5) and 3β-acetoxy-27-cis-caffeoyloxyolean-12-en-28-oic acid methyl ester (6)) identified by 1D and 2D NMR, UV, IR and MS analyses. Among these, waltherione C exhibited the highest and selective antitrypanosomal activity towards T. cruzi (IC50=1.93 μM) with low cytotoxicity (IC50=101.23 μM), resulting in a selectivity index value of 52. Waltherione C conforms to hit activity criteria with respect to T. cruzi as required by the WHO/TDR.

Abstract
CONTEXT Oxidative stress is an important factor modulating skin alterations. Melochia arenosa Benth. (Malvaceae) is a Brazilian plant with antimicrobial activity and antioxidant potential. OBJECTIVE The objective of this study is to develop a topical formulation containing antioxidant phenolic-rich extract of M. arenosa and to evaluate its skin permeation profile. MATERIALS AND METHODS Response surface methodology was used to maximize the total phenolic (TP) content of the extract and its antioxidant activity was evaluated by 2,2-diphenyl-1-picryl-hydrazyl (DPPH), 2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), and respiratory burst methods. An emulsion containing 1% optimized extract (OE) was developed and employed photoacoustic spectroscopy (PAS) for the determination of its skin permeation profile. The morphology of the skin was studied in histological sections stained with hematoxylin-eosin. RESULTS AND DISCUSSION The optimum conditions predicted for the major extractive efficiency of the phenolics with 100% ethanol led extraction time 101 h and plant:solvent proportion 1:13.5 (w/v). OE presented TP = 724.6 ± 8.2 mg GAE/g extract and scavenging capacity of DPPH (IC50 value = 11.43 ± 0.14 µg/mL) and ABTS radicals (IC50 value = 35.42 ± 0.48 µg/mL). The production of ROS by neutrophils after stimulation with phorbol miristate acetate was lower when the OE was present in the reaction medium, endorsing its high antioxidant capacity. The data obtained by PAS indicated that the OE present in the emulsion has permeated and was distributed in the whole skin. No histopathological alterations were observed in the histological analysis. CONCLUSION The formulation developed is a promising tool for skin care and could prevent the damage caused by oxidative stress.

Abstract
The methanol extract of the aerial part of Triumfetta grandidens (Tiliaceae) was highly active against Meloidogyne incognita, with second-stage juveniles (J2s) mortality of 100% at 500 μg/mL at 48 h post-exposure. Two 4-quinolone alkaloids, waltherione E (1), a new alkaloid, and waltherione A (2), were isolated and identified as nematicidal compounds through bioassay-guided fractionation and instrumental analysis. The nematicidal activities of the isolated compounds against M. incognita were evaluated on the basis of mortality and effect on egg hatching. Compounds 1 and 2 exhibited high mortalities against J2s of M. incognita, with EC50 values of 0.09 and 0.27 μg/mL at 48 h, respectively. Compounds 1 and 2 also exhibited a considerable inhibitory effect on egg hatching, which inhibited 91.9 and 87.4% of egg hatching, respectively, after 7 days of exposure at a concentration of 1.25 μg/mL. The biological activities of the two 4-quinolone alkaloids were comparable to those of abamectin. In addition, pot experiments using the crude extract of the aerial part of T. grandidens showed that it completely suppressed the formation of gall on roots of plants at a concentration of 1000 μg/mL. These results suggest that T. grandidens and its bioactive 4-quinolone alkaloids can be used as a potent botanical nematicide in organic agriculture.

Abstract
The family Sterculiaceae is one of the most important families among flowering plants. Many of its members demonstrate medicinal properties and have been used for the treatment of various ailments and wounds. A wide range of compounds including alkaloids, phenyl propanoids, flavonoids, terpenoids and other types of compounds including hydrocarbons, sugars, quinones, phenolic acids, lactones, lignans, amine and amides have been isolated from several species in this family. Few studies have reported that some extracts and single compounds isolated from this family exhibited several biological activities, such as antimicrobial, anti-inflammatory, antioxidant and cytotoxic activities. The present review is an effort to provide information about the traditional uses, phytochemistry and pharmacology of species from family Sterculiaceae, and to uncover the gaps and potentials requiring further research opportunities regarding the chemistry and pharmacy of this family.

Abstract
The analgesic potential of six 14-membered-ring cyclopeptide alkaloids, namely, franganine (1), discarine B (2), scutianines B (3), C (4), and D (5), and adouetine X (6), have been investigated. Among the compounds tested, only franganine (1) and adouetine X (6) produced antinociceptive effects in a mouse model of acute pain, without inducing undesirable side effects. Furthermore, compound 6 also exhibited a pronounced analgesic effect in a chronic neuropathic pain model in mice. It has been found that adouetine X (6) can decrease the activities of Ca(2+)-ATPase and Na(+)/K(+)-ATPase in vitro. Thus, the present findings have demonstrated that adouetine X (6) is a promising analgesic agent.
