Abstract
The aim of this study is to analyse the phytochemical composition, anti-oxidant activity, FT-IR and GC-MS analysis of Simarouba glauca leaf extracts. The chloroform extract exhibited highest T.P.C. (139.82 ± 0.06 mg/g GAE) and highest T.F.C. (41.95 ± 0.50 mg/g QE). The GC-MS analysis confirmed the presence of ten compounds in acetone extract and twenty-two compounds in methanol extract. The GC-MS analysis of acetone fraction showed the major peaks such as Glycerine (13.20%), 1,1,1-trichloro-2-methyl-2-propanol (8.92%), Cyclohexanol,2-methyl-5-(1-methylethenyl)- (6.09%), Tetradecane, 2,6,10-trimethyl (7.68%) and Phytol (7.53%). Some of these compounds exhibit anti-oxidant activities. GC-MS analysis of methanol fraction exhibited the presence of following compounds: Undecane (8.52%), 2,3-Trimethylene-4-pyrone (1.79%), cis-Sinapyl alcohol (2.33%) and Umckalin (1.19%). The acetone and methanol fractions exhibited higher percentage of inhibition in DPPH assay. The overall results of this study indicate that the acetone and methanol fractions have been demonstrated to be efficacious against various diseases.

Mugaranja KP, Kulal A. Investigation of effective natural inhibitors for starch hydrolysing enzymes from Simaroubaceae plants by molecular docking analysis and comparison with in-vitro studies. Heliyon 2022; 8:e09360. [PMID: 35600433 PMCID: PMC9118686 DOI: 10.1016/j.heliyon.2022.e09360] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2021] [Revised: 11/22/2021] [Accepted: 04/27/2022] [Indexed: 11/25/2022] Open
Abstract
The present study aims to find the effective natural enzyme inhibitors against alpha-amylase and alpha-glucosidase from the array of compounds identified in plants of the Simaroubaceae family using molecular docking and ADME/Toxicity studies. Among the 218 compounds docked against seven enzymes, buddlenol-A and citrusin-B showed the best binding energies (kcal/mol) of -7.830 and -7.383 against human salivary alpha-amylase and pancreatic alpha-amylase respectively. The other two compounds 9-hydroxycanthin-6-one and bruceolline-B had the best binding energy of -6.461 and -7.576 against N-terminal and C-terminal maltase glucoamylase respectively. Whereas the binding energy of prosopine (-6.499) and fisetinidol (-7.575) was considered as the best against N-terminal and C-terminal sucrase-isomaltase respectively. Picrasidine-X showed the best binding energy (-7.592) against yeast alpha-glucosidase. The study revealed that the seven compounds which showed the best binding energy against respective enzymes are considered as the ‘lead hit compounds’. Even though the ‘lead hit compounds’ are not obeying all the laws of ADMET, the drug-likeness properties of 9-hydroxycanthin-6-one, fisetinidol, picrasidine-X, and prosopine were considerable. Also, kaempferol-3-O-pentoside was the recent compound identified from the Simarouba glauca plant extract found to be one among the top five lead hit compounds against four enzymes. This study provides valuable insight into the direction of developing natural compounds as potential starch hydrolysing enzyme inhibitors for managing type 2 diabetes.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Different species of the Simaroubaceae family are used in traditional medicine to treat malaria. Among these is Homalolepis suffruticosa (syn. Simaba suffruticosa and Quassia suffruticosa), which is native to Central Brazil and popularly known as calunga. However, there is a lack of investigation concerning its antimalarial effects. AIM OF THE STUDY To investigate the antiplasmodial and cytotoxic effects of the isolated metabolites and methanol extract from H. suffruticosa roots as well as to conduct the dereplication of this extract aiming to characterize its metabolic profile by UPLC-DAD-ESI-MS/MS. MATERIALS AND METHODS Methanol extract of the H. suffruticosa roots and six isolated compounds were evaluated against chloroquine-resistant Plasmodium falciparum W2 strain by the PfLDH method and cytotoxicity in HepG2 cells by the MTT assay. Dereplication of the extract was performed by UPLC-DAD-ESI-MS/MS. RESULTS The six isolated compounds disclosed high to moderate antiplasmodial activity (IC50 0.0548 ± 0.0083 μg/mL to 26.65 ± 2.40 μg/mL) and cytotoxicity was in the range of CC50 0.62 ± 0.33 μg/mL to 56.43 ± 2.54 μg/mL, while 5-metoxycantin-6-one proved to be the most potent constituent of the six assayed ones. The methanol extract of the roots showed high in vitro antiplasmodial activity (IC50 1.88 ± 0.56 μg/mL), moderate cytotoxicity (CC50 41.93 ± 2.30 μg/mL), and good selectivity index (SI = 22.30). Finally, C20 quassinoids and canthin-6-one alkaloids were putatively identified in the H. suffruticosa methanol extract by LC-MS. CONCLUSIONS Taken together, the isolated compounds, mainly the 5-metoxycantin-6-one and the methanol extract from H. suffruticosa roots, disclose good antiplasmodial activity, supporting the ethnopharmacological history of the Simaroubaceae species as traditional antimalarial drugs.

Abstract
Background and objective: Simarouba glauca is a plant belonging to the family of Simaroubaceae. It is a potent source of secondary metabolites. The aim of this study was to evaluate the apoptotic properties of leaf extracts of Simarouba glauca against human leukemic cancer cells. Materials and Methods: Cytotoxicity of Simarouba glauca was assessed in the leaf extract of petroleum ether against leukemic cells by MTT assay. To detect the apoptotic features, fluorescence microscopy analysis was done with dual acridine orange/ethidium bromide fluorescent staining and Hoechst staining. To determine the externalization of phosphatidylserine, annexin v staining was done. Mitochondrial or death receptor activation was confirmed by caspase 3 analysis by flow cytometry. Results: This study revealed that Simarouba glauca was able to treat leukemia. Among the four extracts, petroleum ether extract showed a higher order of in vitro anticancer activity. The petroleum ether extract strongly inhibited the proliferation of K562 cell lines with IC50 values of 186 µg/ml. Dual acridine orange/ethidium bromide fluorescent staining and Hoechst staining revealed the characteristic features of apoptosis. Annexin V confirmed early and late stage apoptosis. Caspase-3 analysis revealed that cell death was due to mitochondrial or death receptor activation in mitochondrial pathway. Conclusion: These findings suggested that Simarouba glauca leaf extracts inhibited leukemic cells in a time- and dose-dependent manner either through mitochondrial or death receptor activation. The leaf extracts of Simarouba glauca was found to be nontoxic to lymphocytes. It can be concluded that Simarouba glauca is an important source of phytochemicals posing efficacy against leukemic cancer cells.

Abstract
Species of the genus Simarouba have been studied because of their antimalarial and antileukemic activities. A group of oxygenated terpenes called quassinoids have been isolated from species of the Simarouba genus, and are responsible for its therapeutic properties. We hypothesized that Simarouba tulae, an endemic plant from Puerto Rico, is a natural source rich in quassinoid compounds with anticancer activity. The leaves were processed and extracted with solvents of different polarities. The extracts were screened for their antiproliferative activity, and it was shown that the chloroform extract was the most active extract. This extract was purified using different chromatographic techniques to afford the quassinoid simalikalactone D (SKD). This compound was further characterized using NMR and X-ray diffraction analysis. A reassessment of original structural assignments for SKD is proposed. SKD showed high cytotoxicity activity, with an IC50 of 55, 58, and 65 nM in A2780CP20 (ovarian), MDA-MB-435 (breast), and MDA-MB-231 (breast) cell lines, respectively. Exposure to SKD led to 15% inhibition of the migration of MDA-MB-231 cells.

Abstract
Endemic in 149 tropical and subtropical countries, neglected tropical diseases (NTDs) affect more than 1 billion people annually, including 875 million children in developing economies. These diseases are also responsible for over 500,000 deaths per year and are characterized by long-term disability and severe pain. The impact of the combined NTDs closely rivals that of malaria and tuberculosis. Current treatment options are associated with various limitations including widespread drug resistance, severe adverse effects, lengthy treatment duration, unfavorable toxicity profiles, and complicated drug administration procedures. Natural products have been a valuable source of drug regimens that form the cornerstone of modern pharmaceutical care. In this review, we highlight the potential that remains untapped in natural products as drug leads for NTDs. We cover natural products from plant, marine, and microbial sources including natural-product-inspired semi-synthetic derivatives which have been evaluated against the various causative agents of NTDs. Our coverage is limited to four major NTDs which include human African trypanosomiasis (sleeping sickness), leishmaniasis, schistosomiasis and lymphatic filariasis.

Abstract
The growing incidence of parasitic resistance against generic pentavalent antimonials, specifically for visceral disease in Indian subcontinent, is a serious issue in Leishmania control. Notwithstanding the two treatment alternatives, that is amphotericin B and miltefosine are being effectively used but their high cost and therapeutic complications limit their use in endemic areas. In the absence of a vaccine candidate, identification, and characterization of novel drugs and targets is a major requirement of leishmanial research. This review describes current drug regimens, putative drug targets, numerous natural products that have shown promising antileishmanial activity alongwith some key issues and strategies for future research to control leishmaniasis worldwide.

Abstract
Plasmodium falciparum and P. vivax malaria parasites are now resistant, or showing signs of resistance, to most drugs used in therapy. Novel chemical entities that exhibit new mechanisms of antiplasmodial action are needed. New antimalarials that block transmission of Plasmodium spp. from humans to Anopheles mosquito vectors are key to malaria eradication efforts. Although P. vivax causes a considerable number of malaria cases, its importance has for long been neglected. Vivax malaria can cause severe manifestations and death; hence there is a need for P. vivax-directed research. Plants used in traditional medicine, namely Artemisia annua and Cinchona spp. are the sources of the antimalarial natural products artemisinin and quinine, respectively. Based on these compounds, semi-synthetic artemisinin-derivatives and synthetic quinoline antimalarials have been developed and are the most important drugs in the current therapeutic arsenal for combating malaria. In the Amazon region, where P. vivax predominates, there is a local tradition of using plant-derived preparations to treat malaria. Here, we review the current P. falciparum and P. vivax drug-sensitivity assays, focusing on challenges and perspectives of drug discovery for P. vivax, including tests against hypnozoites. We also present the latest findings of our group and others on the antiplasmodial and antimalarial chemical components from Amazonian plants that may be potential drug leads against malaria.

Abstract
Six new polyketides, simplexolides A-E (1-5) and a furan ester, plakorfuran A (6), together with four known furanylidenic methyl esters (7-10) were isolated from the marine sponge Plakortis simplex. Compounds 1-5 feature a tetrahydrofuran ring opened seco-plakortone skeleton. These new structures, including relative configurations, were determined on the basis of extensive analysis of spectroscopic data. The absolute configurations of 1-6 were established by the modified Mosher's method, and the CD exciton chirality method. However, configurations of the remote stereocenters at C-8 in compounds 1-5 were not determined. Antifungal, cytotoxicity, antileismanial, and antimalarial activities of these poly-ketides were evaluated.

Abstract
Quassia amara L. (Simaroubaceae) is a species widely used as tonic and is claimed to be an efficient antimalarial all over the Northern part of the Amazon basin. Quassinoid compound Simalikalactone D (SkD) has been shown to be one of the molecules responsible for the antiplasmodial activity of a watery preparation made out of juvenile fresh leaves of this plant. Because of its strong antimalarial activity, we decided to have a further insight of SkD pharmacological properties, alone or in association with classical antimalarials. At concentrations of up to 200μM, we showed herein that SkD did not exert any apoptotic or necrotic activities in vitro on lymphoblastic cells. However, an antiproliferative effect was evident at concentrations higher than 45nM. SkD was inefficient at inhibiting heme biomineralization and the new permeability pathways induced by the parasite in the host erythrocyte membrane. With respect to Plasmodium falciparum erythrocytic stages, SkD was almost inactive on earlier and later parasite stages, but potently active at the 30th h of parasite cycle when DNA replicates in mature trophozoites. In vitro combination studies with conventional antimalarial drugs showed that SkD synergizes with atovaquone (ATO). The activity of ATO on the Plasmodium mitochondrial membrane potential was enhanced by SkD, which on its own had a poor effect on this cellular parameter.

Abstract
Albizia schimperiana Oliv. (Leguminosae) is a tree distributed in the highland of Kenya, where it is used as a traditional medicine for the treatment of bacterial and parasitic infections, notably pneumonia and malaria, respectively. Bioassay guided isolation of the CH2Cl2–MeOH 1:1/ MeOH-H2O 9:1 (mixed) extract of A. schimperiana afforded the new bioactive macrocyclic spermine alkaloid, namely 5, 14-dimethylbudmunchiamine L1 (1) and three known budmunchiamine analogs 2-4. The structures of the compounds 1-4 were determined by 1D and 2D NMR data, including COSY, HMQC, and HMBC experiments, and ESI-HRMS. Compounds 1 and 3 exhibited significant in vitro antimicrobial activity against a panel of microorganisms, including C. neoformans, methicillin-resistant S. aureus, E. coli, M. intracellulare, and A. fumigatus. In addition, they demonstrated strong in vitro antimalarial activities against chloroquine-susceptible (D6) and -resistant (W2) strains of Plasmodium falciparum with IC50s ranging from 120-270 ng/mL. Compounds 1-4 were also evaluated for cytotoxic activity against selected human cancer cell lines and mammalian kidney fibroblasts (VERO cells). It was observed that hydroxyl substitution of the side chain of the budmunchiamines dramatically reduced the cytotoxicity and antimicrobial activity of the alkaloids 2 and 4 without decreasing antimalarial activity.

Abstract
The genus Acanthostrongylophora is famous for producing a wide array of manzamine alkaloids as natural hydrochloride salts. An examination of A. ingens has now yielded two tertiary bases, (+)-8-hydroxymanzamine A (1) and (+)-manzamine A (2), by chromatography over alumina using CHCl3-MeOH-NH3·H2O as solvent. In addition, (+)-8-hydroxymanzamine A hydrochloride (3) and (+)-manzamine A hydrochloride (4) were isolated under the same conditions from the same source by silica gel chromatography. The structures of 1-4 were determined from 1D- and 2D-NMR spectra and by circular dichroism experiments, and the spectral features of the bases 1 and 2 were found to be different from those of the salts 3 and 4. Compounds 3 and 4 were deprotonated by both Al2O3 and strong base to afford 1 and 2, which were converted again to their respective salts 3 and 4. Both the compounds 1 and 3 showed equally potent in vitro antimalarial activity against chloroquine-sensitive (D6) and –resistant (W2) strains of P. falciparum (IC50= 19.5 and 22.0 ng/mL vs. 27.0 and 36.5 ng/mL, respectively), while 2 was >3-fold less potent than 4 (IC50= 20.8 and 25.8 ng/mL vs. 6.1 and 7.3 ng/mL, respectively). Compounds 1, 3 and 4 showed good antimicrobial activities against methicillin-resistant Staphylococcus aureus and Mycobacterium intracellulare and antileishmanial activity against Leishmania donovani promastigotes. In contrast, manzamine A base (2) showed relatively weaker antimicrobial, antileishmanial and cytotoxic activities [towards cancer (HepG2: Human hepatocellular carcinoma or hepatoma), and non-cancer cells (VERO: Monkey kidney fibroblast; LLC-PK11: Pig kidney epithelial)], compared with salt 4.

Abstract
Two kaurane diterpenes, namely cafestol (1) and kahweol (2), were isolated from hydrolyzed fraction of the fixed oil of Ethiopian Coffea arabica unroasted beans, using AgNO3-impregnated silica gel chromatography. In addition, cafestol palmitate (3) and kahweol palmitate (4), the two natural diterpene esters of C. arabica, were also synthesized. Compounds 1–4 were evaluated for anti-inflammatory activity using cyclooxygenase-2 (COX-2), cell aggregation, cell proliferation, cell adhesion, iNOS and antioxidant assays. The COX-2 inhibitory activity of cafestol (1) was found to be 20-fold more potent than kahweol (2) (IC50 value 0.25 μg/mL vs. 5.0 μg/mL), while compounds 3 and 4 were weakly active. The isolation and structure elucidation of the diterpenes 1 and 2, preparation of compounds 3 and 4, and their biological activities are presented in this paper.

Abstract
In the present study, a quassinoid, neosergeolide, isolated from the roots and stems of Picrolemma sprucei (Simaroubaceae), the indole alkaloids ellipticine and aspidocarpine, isolated from the bark of Aspidosperma vargasii and A. desmanthum (Apocynaceae), respectively, and 4-nerolidylcatechol, isolated from the roots of Pothomorphe peltata (Piperaceae), all presented significant in vitro inhibition (more active than quinine and chloroquine) of the multi-drug resistant K1 strain of Plasmodium falciparum. Neosergeolide presented activity in the nanomolar range. This is the first report on the antimalarial activity of these known, natural compounds. This is also the first report on the isolation of aspidocarpine from A. desmanthum. These compounds are good candidates for pre-clinical tests as novel lead structures with the aim of finding new antimalarial prototypes and lend support to the traditional use of the plants from which these compounds are derived.

Abstract
Malaria caused by protozoa of the genus Plasmodium, because of its prevalence, virulence, and drug resistance, is the most serious and widespread parasitic disease encountered by mankind. The inadequate armory of drugs in widespread use for the treatment of malaria, development of strains resistant to commonly used drugs such as chloroquine, and the lack of affordable new drugs are the limiting factors in the fight against malaria. These factors underscore the continuing need of research for new classes of antimalarial agents, and a re-examination of the existing antimalarial drugs that may be effective against resistant strains. This review provides an in-depth look at the most significant progress made during the past 10 years in antimalarial drug development.

Abstract
5-episinuleptolide (1) is an abundant norcembranolide diterpene isolated from several species of the soft coral genus Sinularia. Biocatalytic transformation studies of 1 using Streptomyces lavendulea ATCC 8664 resulted in the isolation and characterization of two new metabolites 2 and 3. Compound 2, 6alpha-hydroxy-5-episinuleptolide was produced via a stereoselective reduction of 1 and was further metabolized into compound 3 which has a 3,8-bicylized cembranoid skeleton. The structures and configurations of the metabolites were determined by spectroscopic and X-ray crystallographic analyses.

Abstract
French Guiana (North-East Amazonia) records high malaria incidence rates. The traditional antimalarial remedy most widespread there is a simple tea made out from Quassia amara L. leaves (Simaroubaceae). This herbal tea displays an excellent antimalarial activity both in vitro and in vivo. A known quassinoid, simalikalactone D (SkD), was identified as the active compound, with an IC(50) value of 10nM against FcB1 Plasmodium falciparum chloroquine resistant strain in vitro. Lastly, it inhibits 50% of Plasmodium yoelii yoelii rodent malaria parasite at 3.7 mg/kg/day in vivo by oral route. These findings confirm the traditional use of this herbal tea.

Abstract
Several N-substituted quindolines were made to further evaluate the role of N-alkylation on the activity of indoloquinolines as antifungal agents. While N-5 substitution is required for these activities, N-10 alkylation alone leads to inactive products but is tolerated in the presence of N-5 alkyl groups. It was also discovered that bis-quindolines appear to have a more expanded antimicrobial spectrum and lower cytotoxicity than their monomeric counterparts.
