Abstract
Aquatic animals are known for their myriad of beneficial bacteria with diverse biologically active compounds. The current study was aimed to isolate and characterize potentially beneficial lactic acid bacteria from Nile Tilapia and evaluate their pharmaceutical applications. The fish samples were dissected and stomach, intestine, and gills were collected and serially diluted for the isolation of lactic acid bacteria (LAB) on BCP agar media. Identification of isolate was carried by biochemical and molecular characterization using API kit and 16S rRNA gene sequencing analysis, respectively. Further, KS-TN11 was assessed for α-glucosidase inhibitory potential using the chromogenic method. A lactic acid bacterium KS-TN11 was isolated from the stomach of Nile Tilapia and identified as Leuconostoc mesenteroides. Effect of KS-TN11 on lipid accumulation in adipocytes was done by using Oil Red O staining. The isolate showed strong antibacterial activity against a number of pathogenic bacteria in vitro. In addition, L. mesenteroides KS-TN11 KS-TN11 (50 mg/ml and 100 mg/ml) tends to inhibit adipogenesis in 3T3-L1 adipocytes and thus may have possible anti-obesity effects. Moreover, L. mesenteroides KS-TN11 exhibited substantial α–glucosidase inhibitory activities by 41.33% at 50 mg/ml and 64% at 100 mg/ml, respectively. The bacterium showed potent antibacterial activity against a number of pathogenic bacteria; in addition to alpha-glucosidase activity, and inhibition of lipid accumulation in 3T3-L1 cell line. These results reinforce KS-TN11 as a novel bacterium with an impending pharmaceutical application.

Abstract
To estimate the effect of methyl group of dihydroguaiaretic acid, which shows many kinds of biological activities, on biological activity, both enantiomers of 9'-dehydroxyimperanene (5, 6) and 7,8-dihydro-9'-dehydroxyimperanene (7, 8) lacking one of the methyl groups of dihydroguaiaretic acid were synthesized. (S)-7,8-Dihydro-9'-dehydroxyimperanene (7) showed 4-6-fold higher cytotoxic activity than all stereoisomers of dihydroguaiaretic acid (2-4). The IC50 values of (S)-7,8-dihydro-9'-dehydroxyimperanene (7) against HL-60 and HeLa cells were 6.1μM and 5.6μM, respectively. Though only one of three stereoisomers of dihydroguaiaretic acid showed antibacterial activity against a gram negative bacterium, both enantiomers of 5-8 showed antibacterial activity against a gram negative bacterium. This is a Letter on biological activity of 9-norlignan, in which one of methyl groups of lignan is absent.

Abstract
The prevalence and severity of obesity has increased markedly in recent decades making it a global public health concern. Since obesity is a potential risk factor in the development of hypertension, type-2 diabetes, cardiovascular diseases, infertility, etc., it is no more viewed as a cosmetic issue. Currently, only a few FDA-approved anti-obesity drugs like Orlistat, Lorcaserin and Phentermine-topiramate are available in the market, but they have considerable side effects. On the other hand, bariatric surgery as an alternative is associated with high risk and expensive. In view of these there is a growing trend towards natural product-based drug intervention as one of the crucial strategies for management of obesity and related ailments. In Asian traditional medicine and Ayurvedic literature a good number of plant species have been used and quoted for possible lipid-lowering and anti-obesity effects; however, many of them have not been evaluated rigorously for a definite recommendation and also lack adequate scientific validation. This review explores and updates on various plant species, their used parts, bioactive components and focuses multiple targets/pathways to contain obesity which may pave the way to develop novel and effective drugs. We also summarised different drugs in use to treat obesity and their current status. Nature is future promise of our wellbeing.

Abstract
Cytotoxic activities of synthesized lignan derivatives were estimated by WST-8 reduction assay against HL-60 and HeLa cells to show the structure-activity relationship. The activities of some effective compounds were examined against Colon 26 and Vero cells. Dietary secoisolariciresinol (SECO, 1) and its metabolite, 9,9'-anhydrosecoisolariciresinol (2), did not show the cytotoxic activity. On the other hand, all stereoisomers of dihydroguaiaretic acid (DGA, 9,9'-dehydroxysecoisolariciresinol, 3-5) exhibited the activity (IC50: around 30 μM). The IC50 value of (8R,8'R)-9-butyl DGA derivative 13 was around 6 μM. This fact means that the hydrophobic group was advantageous for higher activity at 9- and 9'-positions. By the evaluation of the effect of 7and 7'-aryl group on the activity, we discovered the highest activity of (8R,8'R)-7-(3-hydroxy-4-methoxyphenyl)-7'-(2-ethoxyphenyl) DGA derivative 47 showing around 1 μM of IC50 value, which is about 24-fold higher activity than that of natural (8R,8'R)-DGA. The derivative of dietary lignan showed the high cytotoxic activity.

Biochim Biophys Acta Gen Subj 2011; 1820:461-8.

Abstract
BACKGROUND Nobiletin is a citrus flavonoid which possesses the flavone structure with six methoxy groups. Although nobiletin has been reported to display anti-inflammatory, anti-tumor, and anti-diabetes activities, its effect on adipocyte differentiation remained unclear. In the present study, we investigated the effect of nobiletin on the differentiation of 3T3-L1 preadipocytes into adipocytes. METHODS 3T3-L1 preadipocytes were treated with nobiletin under various differentiation conditions. The effect of nobiletin on adipocyte differentiation was evaluated by oil red O staining, real-time RT-PCR, and Western blotting. RESULTS Nobiletin significantly suppressed the differentiation of 3T3-L1 preadipocytes into adipocytes, upon induction with insulin together with a cAMP elevator such as 3-isobutyl-1-methylxanthine (IBMX), by downregulating the expression of the gene encoding peroxisome proliferator-activated receptor (PPAR) γ2. In addition, nobiletin decreased the phosphorylation of cAMP-response element-binding protein (CREB) and strongly enhanced the phophorylation of signal transducer and activator of transcription (STAT) 5. GENERAL SIGNIFICANCE Nobiletin has a suppressive effect on the differentiation of preadipocytes into adipocytes when cells were induced with a general differentiation cocktail such as insulin, IBMX, and dexamethasone.

Abstract
Flaxseed lignan, secoisolariciresinol has been reported to possess health benefits. We previously synthesized each stereoisomer of secoisolariciresinol and found that (-)-secoisolariciresinol reduces lipid accumulation and induces adiponectin production in 3T3-L1 adipocytes. Here we show the effects of (-)-secoisolariciresinol on high-fat diet-induced obesity in C57BL/6 male mice. Oral administration of (-)-secoisolariciresinol for 28 consecutive days significantly suppressed the gain of body weight. Increased serum adiponectin level and decreased gene expression of fatty acid synthase and sterol regulatory element-binding protein-1c in liver, which are related to fatty acid synthesis, were observed in the mice orally administered with (-)-secoisolariciresinol. In addition, subcutaneous injection of (-)-secoisolariciresinol also significantly suppressed the gain of body weight. Serum leptin levels were significantly increased by treating with (-)-secoisolariciresinol or (-)-enterolactone. Subcutaneous injection of (-)-secoisolariciresinol, (-)-enterolactone, or (-)-enterodiol promoted gene expression of acyl-CoA oxidase, carnitine palmitoyl transferase-1, and peroxisome proliferator-activated receptor α, which are related to β-oxidation. Overall results suggest that (-)-secoisolariciresinol exerts a suppressive effect on the gain of body weight of mice fed a high-fat diet by inducing gene expression of adiponectin, resulting in the altered expression of various genes related to the synthesis and β-oxidation of fatty acids.
