Sohn, Young-Sik,Lee, Yu-No,Park, Chan-In,Hwang, S-Wan,Kim, Song-Mi,Baek, A-Young,Son, Min-Ky,Suh, Jung-Keun,Kim, Hyong-Ha,Lee, Keun-Woo Korean Chemical Society 2011 Bulletin of the Korean Chemical Society Vol.32 No.1
Peroxisome proliferator-activated receptors (PPARs) are members of nuclear receptors and their activation induces regulation of fatty acid storage and glucose metabolism. Therefore, the $PPAR\gamma$ is a major target for the treatment of type 2 diabetes mellitus. In order to generate pharmacophore model, 1080 known agonists database was constructed and a training set was selected. The Hypo7, selected from 10 hypotheses, contains four features: three hydrogen-bond acceptors (HBA) and one general hydrophobic (HY). This pharmacophore model was validated by using 862 test set compounds with a correlation coefficient of 0.903 between actual and estimated activity. Secondly, CatScramble method was used to verify the model. Hence, the validated Hypo7 was utilized for searching new lead compounds over 238,819 and 54,620 chemical structures in NCI and Maybridge database, respectively. Then the leads were selected by screening based on the pharmacophore model, predictive activity, and Lipinski's rules. Candidates were obtained and subsequently the binding affinities to $PPAR\gamma$ were investigated by the molecular docking simulations. Finally the best two compounds were presented and would be useful to treat type 2 diabetes.

Purpose: Exaggerated pro-inflammatory reactions during the acute phase of Kawasaki disease (KD) suggest the role of immune dysregulation in the pathogenesis of KD. We investigated the profiles of T regulatory cells and their correlation with the clinical course of KD. Methods: Peripheral blood mononuclear cells were collected from 17 KD patients during acute febrile and subacute afebrile phases. T cells expressing CD4, CD25, and Foxp3 were analyzed using flow cytometry, and the results were correlated with the clinical course of KD. Results: The percentage of circulating $CD4^+CD25^{high}Foxp3^+$ T cells among $CD4^+$ T cells was Significantly higher during the subacute afebrile phase than during the acute febrile phase ($1.10%{\pm}1.22%$ vs. $0.55%{\pm}0.53%$, P=0.049). Although levels of $CD4^+CD25^{low}Foxp3^+$ T cells and $CD4^+CD25^-Foxp3^+$ T cells were only slightly altered, the percentage of $CD4^+CD25^+Foxp3^-$ T cells among $CD4^+$ T cells was significantly lower during the subacute afebrile phase than during the acute febrile phase ($2.96%{\pm}1.95%$ vs. $5.64%{\pm}5.69%$, P=0.036). Consequently, the ratio of $CD25^{high}Foxp3^+$ T cells to $CD25^+Foxp3^-$ T cells was higher during the subacute afebrile phase than during the acute febrile phase ($0.45%{\pm}0.57%$ vs. $0.13%{\pm}0.13%$, P=0.038). Conclusion: Decreased $CD4^+CD25^{high}Foxp3^+$ T cells and/or an imbalanced ratio of $CD4^+CD25^{high}Foxp3^+$ T cells to $CD4^+CD25^+Foxp3^-$ T cells might playa role in KD development. Considering that all KD patients were treated with intravenous immunoglobulin (IVIG), recovery of $CD4^+CD25^{high}Foxp3^+$ T cells during the subacute afebrile phase could be a mechanism of IVIG.

Fundamental study was carried out to elucidate the mechanisms of biological degradation of dyestuff in environments. A few bacterial strains which were capable of degrading amarnath were obtained from soil through an extensive screening program and identified by microbiolological properties. Conditions for bacterial growth and amaranth degradation were characterized and optimized, and the degradation products were identified. The results were as follows. 1. The most active strain A12-1 to be capable of degradation of amaranth was identified as Pseudomonas sp. 2. Optimal conditions for growth of the strain A12-1 were:35℃ and pH 7.5, and growth was markedly increaesd by aeration. 3. Degradation of amaranth by the strain was accessed under similar conditions for growth, however significantly inhibited when the culture was aerated. 4. Both bacterial growth and amaranth degradation were gradually decreased with increased concentration of amaranth in the culture. 5. Reaction of the crude enzyme from the strain A12-1 was optimal at 35℃ and pH 7.5 for degrading amaranth. 6. Sodium naphthionate and R-amino salt were found to be the products of amaranth degradation by the strain A12-1.

<P><I>Bojesodok-eum</I> (BSE) is a herbal prescription consisting of <I>Coptidis Rhizoma</I> and <I>Scutellariae Radix</I> as main components. This paper investigated the effects of BSE on the induction of nitric oxide (NO), prostaglandin E<SUB>2</SUB> (PGE<SUB>2</SUB>), and proinflammatory cytokines that are caused by lipopolysaccharide (LPS) in murine macrophage cell line and on the paw edema formation in animals. Administration of BSE (0.3 g/kg and 1 g/kg) in rats significantly inhibited carrageenan-induced paw edema formation, as did dexamethasone, an anti-inflammatory positive control drug. In cell model, treatment of BSE decreased the production of NO and PGE<SUB>2</SUB> in RAW264.7 cells stimulated by LPS. BSE also inhibited the expression of iNOS and COX-2 protein as well as COX activity in a concentration-dependent manner. Consistently, BSE suppressed the ability of LPS to produce TNF-<I>α</I>, interleukin-1<I>β</I>, and interleukin-6. LPS treatment induced nuclear NF-<I>κ</I>B level and I-<I>κ</I>B<I>α</I> phosphorylation, which were inhibited subsequent treatment of BSE, suggesting its repression of LPS-inducible NF-<I>κ</I>B activation. BSE abrogated the induction of NO, PGE<SUB>2</SUB>, and proinflammatory cytokines, as well as iNOS and COX-2 protein expression in RAW264.7 cells stimulated by LPS as mediated with NF-<I>κ</I>B inhibition.</P>

Background/Aims: In this systematic review and meta-analysis, we aimed to clarify the effect of obesity on the occurrence of and mortality from primary liver cancer. Methods: This study was conducted using a systematic literature search of MEDLINE, EMBASE, and the Cochrane Library until November 2018 using the primary keywords “obesity,” “overweight,” “body mass index (BMI),” “body weight,” “liver,” “cancer,” “hepatocellular carcinoma,” “liver cancer,” “risk,” and “mortality.” Studies assessing the relationship between BMI and occurrence of or mortality from primary liver cancer in prospective cohorts and those reporting hazard ratios (HRs) or data that allow HR estimation were included. Results: A total of 28 prospective cohort studies with 8,135,906 subjects were included in the final analysis. These included 22 studies with 6,059,561 subjects for cancer occurrence and seven studies with 2,077,425 subjects for cancer-related mortality. In the meta-analysis, an increase in BMI was associated with the occurrence of primary liver cancer (HR, 1.69; 95% confidence interval, 1.50-1.90, I<sup>2</sup>=56%). A BMI-dependent increase in the risk of occurrence of primary liver cancer was reported. HRs were 1.36 (95% CI, 1.02-1.81), 1.77 (95% CI, 1.56-2.01), and 3.08 (95% CI, 1.21-7.86) for BMI >25 kg/㎡, >30 kg/㎡, and >35 kg/㎡, respectively. Furthermore, increased BMI resulted in enhanced liver cancer-related mortality (HR, 1.61; 95% CI, 1.14-2.27, I<sup>2</sup>=80%). Conclusions: High BMI increases liver cancer mortality and occurrence of primary liver cancer. Obesity is an independent risk factor for the occurrence of and mortality from primary liver cancer.
