This study aimed to investigate the effects of Cordyceps sinensis extract (CSE) and Gymnema inodorum extract (GIE), used alone and combined, on antiadipogenesis in 3T3-L1 cells. Oil Red O staining was used to examine the effects of these extracts on inhibition of intracellular lipid accumulation in 3T3-L1 adipocytes and on lipid droplet morphology. Fourier transform-infrared (FTIR) microspectroscopy was used to examine biomolecular changes in 3T3-L1 adipocytes. The pancreatic lipase assay was used to evaluate the inhibitory effects of CSE and GIE on pancreatic lipase activity. Taken together, the results indicated that CSE, GIE, and their combination suppressed lipid accumulation. The FTIR microspectroscopy results indicated that CSE, GIE, and their combination had inhibitory effects on lipid accumulation in the adipocytes. Compared with the untreated adipocytes, the signal intensity and integrated areas of glycogen and other carbohydrates, the acyl chain of phospholipids, and the lipid/protein ratios of the CSE, GIE, alone, and combined treated adipocytes were significantly lower (p < 0.05). Combination treatment resulted in a synergistic effect on lipid accumulation reduction in the adipocytes. Principal component analysis of the biomolecular changes revealed six distinct clusters in the FTIR spectra of the sample cells. The pancreatic lipase assay results indicated that CSE and GIE inhibited the pancreatic lipase activity in a dose-dependent manner (mean ± standard error of the mean IC50 values, 2312.44 ± 176.55 μg mL−1 and 982.24 ± 44.40 μg mL−1, resp.). Our findings indicated that FTIR microspectroscopy has potential application for evaluation of the effectiveness of medicinal plants and for the development of infrared biochemical obesity markers useful for treating patients with obesity. These results suggested that use of CSE and GIE alone and in combination may be efficacious as a complementary therapy for hyperlipidemia and obesity management. However, clinical trials in animals and humans must first be completed.

The methanol extract of whole Bacopa monniera plants inhibited pancreatic lipase activity in vitro. From this extract we have reported the isolation of 11 triterpene glycosides and 5 phenylethanoid- and/or phenylpropanoid- glycosides. In this paper, we describe the effects of the methanol extract and/or its constituents on pancreatic lipase activity and the isolation of an active constituent, desrhamnosyl isoacteoside. In addition, the structural requirements for its inhibitory effects were examined. We also examined the effects on the elevation of plasma triglyceride (TG) levels in olive oil loaded mice. The major active constituents, desrhamnosyl isoacteoside and plantainoside B, reduced plasma TG levels in the mice. The inhibitory effects of B. monniera and its constituents on pancreatic lipase activity and plasma TG level are reported for the first time.

Lipase Inhibition

This study aimed to evaluate the potential of marine fungus Purpureocillium lilacinum isolated from an Indonesian marine sponge Stylissa sp. as an anti-obesity agent through pancreatic lipase inhibition assay. The fungus was identified as P. lilacinum through morphological and molecular characteristics. The fungal extract’s inhibition activity and kinetics were evaluated using spectrophotometry and Lineweaver-Burk plots. Ethyl acetate and butanol were used for extraction. Both extracts showed pancreatic lipase inhibition in a concentration-dependent manner. Both crude extracts were then fractionated once. All fractionated extracts showed inhibitory activity above 50%, with the highest activity found in fraction 5 of ethyl acetate at 93.41% inhibition. The best fractionated extract had an IC50value of 220.60 µg.mL-1. The most active fraction of P. lilacinum had a competitive-type inhibitor behavior as shown by the value of Vmax not significantly changing from 388.80 to 382.62 mM pNP.min-1, and the Michaelis-Menten constant (KM) increased from 2.02 to 5.47 mM in the presence of 500 µg.mL-1 fractionated extract. Metabolite identification with LC-MS/MS QTOF suggested that galangin, kaempferol, and quercetin were responsible for the observed lipase inhibition.

The aim of the study was to determine the in vitro enzyme inhibition activities of aqueous polyphenolic extracts of nine popular Bangladeshi vegetables, namely ash gourd, bitter gourd, brinjal, Indian spinach, kangkong, okra, ridge gourd, snake gourd, and stem amaranth. Polyphenolic glycosides were the major compounds present in the extracts. Inhibition of α-amylase (up to 100% at 1 mg/mL) was stronger than α-glucosidase inhibition (up to 70.78% at 10 mg/mL). The Indian spinach extract was the strongest inhibitor of pancreatic lipase activity (IC50 = 276.77 µg/mL), which was significantly better than that of orlistat (381.16 µg/mL), a drug. Ash gourd (76.51%), brinjal (72.48%), and snake gourd (66.82%) extracts were the most effective inhibitors of angiotensin-converting enzyme (ACE), an enzyme whose excessive activities have been associated with hypertension. Brinjal also had a significantly higher renin-inhibitory activity than the other vegetable extracts. We conclude that the vegetable extracts may have the ability to reduce enzyme activities that have been associated with hyperglycemia, hyperlipidemia, and hypertension.

Abstract We studied the effects of recombinant human interleukin-4 (rhIL-4) on megakaryocyte colony formation from enriched hematopoietic progenitors. IL-4 strongly inhibited pure and mixed megakaryocyte colony formation in a dose-dependent manner. Formation of erythroid bursts, eosinophil colonies, and erythrocyte-containing mixed colonies was not affected by the addition of IL-4 as reported previously (Sonoda Y, et al; Blood 75:1615, 1990). Delayed addition experiments suggested that IL-4 acts on an early stage of proliferation of megakaryocyte progenitors. Neutralizing antibodies (antisera) prepared against transforming growth factor beta, tumor necrosis factor alpha, interferon alpha (IFN alpha), and IFN gamma did not affect the inhibitory effects of IL-4 on pure and mixed megakaryocyte colony formation. In addition, the inhibitory effects of IL-4 was also seen in serum-free cultures and in cultures containing highly enriched CD34+, HLA-DR+ cells as a target population. These results indicate that IL-4 may function as one of the negative regulators in human megakaryocytopoiesis in vitro.

Phytochemical Investigation

Scilla species are used as medicinal plants and contain lanosterol-type triterpene glycosides. The phytochemical investigation of the bulbs of Scilla peruviana led to the isolation of 17 compounds, including three new rearranged pentacyclic-lanosterol glycosides (1–3) and two new homoisoflavanone glycosides (12 and 13). The structures of the undescribed compounds were determined by extensive spectroscopic analyses, including two-dimensional (2D) NMR. Among the triterpene glycosides, 2, 3, and 6 showed significant pancreatic lipase inhibitory activity in a concentration-dependent manner in vitro. The oral administration of scillascilloside D-2 (6) reduced serum triglyceride levels in a dose-dependent manner in soybean oil-loaded mice.

ABSTRACT Monocyte-dependent as well as direct inhibitory effects of antimalarial antibodies point toward antigens accessible at the time of merozoite release as targets for biologically active antibodies capable of mediating protection against Plasmodium falciparum. The glutamate-rich protein (GLURP), being an antigen associated with mature schizont-infected erythrocytes, was therefore the object of the present investigation, in which we analyzed whether anti-GLURP antibodies can either interfere directly with merozoite invasion or act indirectly by promoting a monocyte-dependent growth inhibition, antibody-dependent cellular inhibition. GLURP-specific human immunoglobulin G (IgG) antibodies, from pooled IgG of healthy Liberian adults who were clinically immune to malaria, were purified by affinity chromatography on columns containing R0 (N-terminal nonrepetitive region of GLURP) or R2 (C-terminal repetitive region of GLURP) recombinant protein or synthetic peptides as ligands. Analysis of the pattern of reactivity of highly purified anti-GLURP antibodies led to the definition of at least four B-cell epitopes. One epitope was specific for R0, two were specific for R2, and the fourth displayed cross-reactivity between R0 and R2. None of the purified IgG antibodies had direct invasion-inhibitory effects, even at high concentrations. In contrast, when allowed to cooperate with monocytes, all anti-GLURP IgG preparations mediated a strong monocyte-dependent parasite growth inhibition in a dose-dependent manner.

Active Substances

Barley sprouts (BS) contain physiologically active substances and promote various positive physiological functions in the human body. The levels of the physiologically active substances in plants depend on their growth conditions. In this study, BS were germinated using differently colored LED lights and different nutrient supplements. Overall, there were 238 varied BS samples analyzed for their total polyphenol and flavonoid contents. Principal component analysis (PCA) was performed to determine the relationship between the germinated samples and their total polyphenol and flavonoid contents, and those with high levels were further analyzed for their saponarin content. Based on the PCA plot, the optimal conditions for metabolite production were blue light with 0.1% boric acid supplementation. In vitro experiments using the ethanol extract from the BS cultured in blue light showed that the extract significantly inhibited the total lipid accumulation in 3T3-L1 adipocytes and the lipid droplets in HepG2 hepatocytes. These findings suggest that specific and controlled light source and nutrient conditions for BS growth could increase the production of secondary metabolites associated with inhibited fat accumulation in adipocytes and hepatocytes.

Anemarrhena Asphodeloides

Pancreatic lipase is a key enzyme for lipid absorption by hydrolysis of total dietary fats. Therefore, inhibition of pancreatic lipase is suggested to be an effective therapy in the regulation of obesity. The EtOAc-soluble fraction of Anemarrhena asphodeloides rhizomes significantly inhibited pancreatic lipase activity as assessed using porcine pancreatic lipase as an in vitro assay system. Further fractionation of the EtOAc-soluble fraction of A. asphodeloides led to the isolation of a new benzophenone glycoside, zimoside A (1), together with the eleven known compounds iriflophenone (2), 2,4′,6-trihydroxy-4-methoxybenzophenone (3), foliamangiferoside A (4), (2,3-dihydroxy-4-methoxyphenyl)(4-hydroxyphenyl)-methanone (5), 1,4,5,6,-tetrahydroxyxanthone (6), isosakuranetin (7), 4-hydroxybenzoic acid (8), 4-hydroxyacetophenone (9), vanillic acid (10), tyrosol (11) and 5-hydroxymethyl-2-furaldehyde (12). Among the isolated compounds, 3, 5 and 10 showed significant inhibition of pancreatic lipase activity.
