OBJECTIVETo study the antiproliferation effect on HepG2 cells and its underlying mechanism of the active chemical composition of the Viburnum Odoratissimum.

METHODS3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) reduction assay and trypan blue dye exclusion assay were used to assess the effect of vibsane-type diterpenoids on the proliferation of various tumor cells. Alterations in cell cycle and apoptosis were determined by flowcytometry. The enzymatic activity of caspase-3/7 was measured by Apo-ONE homogeneous Caspase-3/7 Assay kit.

RESULTSCompound 1 #, a vibsane-type diterpenoid, was found to significantly inhibit the growth of HepG2 cells by anticancer proliferation activity screening. It was demonstrated that the modified groups on side chain coupled to C11 site affected the cell growth-inhibition activity of compounds by structure-activity analysis. In addition, HepG2 cell line was most sensitive to compound 1 #, which induced growth arrest of HepG2 cells in a dose- and time-dependent manner. Study on the mechanisms underlying these effects indicated that compound 1 # induced significant G0/G1 phase arrest of HepG2 cells in a time- and concentration-dependent manner. Meanwhile, It was found that higher concentrations of compound (5-10 micromol/L) caused evident increase in the unmber of apoptotic cells and dose-dependent activation of caspase-3/7.

CONCLUSIONVibsane-type diterpenoids could significantly inhibit the growth of HCC HepG2 cells. Induction of cell cycle arrest and apoptosis may play important roles in their anticancer effects.

OBJECTIVETo study lymph node micrometastases (LNMM), expression of nm23-H(1), MMP(9), TIMP(2) proteins, and their relationship and clinical significance in patients with stage Dukes B colorectal cancer.

METHODSThirty patients with stage Dukes B colorectal cancer were studied. LNMM in these patients was detected by immunohistochemical anti-cytokeratin 20 (CK20) staining. The expression of nm23-H(1), MMP(9) and TIMP(2) proteins in primary tumors was examined by Strept-avidin-biotin complex method. Clinical-pathological data and survival of each patient were recorded and analyzed.

RESULTS(1) The positive dyeing of CK20 was observed in 26.7% for cases and in 7.8% for lymph nodes of 30 patients with stage Dukes B colorectal cancer. (2) Different expression of nm23-H(1) and MMP(9) proteins in the patients between stage Dukes B and stage Dukes CD was observed (P < 0.05). The decreased nm23-H(1) expression, and/or the increased MMP(9) expression in primary stage Dukes B tumors were significantly associated with LNMM (P < 0.05). Sensitivity and specificity for detection of LNMM by using nm23-H(1) or MMP(9) were respectively 62.5% and 81.8% or 75.0% and 69.8%. If by combining nm23-H(1) with MMP(9), specificity for detection of LNMM became 90.9%. The expression of TIMP(2) protein was not related with stage Dukes and LNMM. (3) The percent of tumor recurrence and/or metastasis for the stage Dukes B patients with LNMM was significantly higher than that for the patients without LNMM (P < 0.05), but the survival percent for the patients with LNMM was significantly lower than that for the patients without LNMM. The outcome for the patients with nm23-H(1) (-) LNMM (+) or MMP(9) (+) LNMM (+) was significantly worse than that for patients with nm23-H(1) (+) LNMM (-) or MMP(9) (+) LNMM (-) (P < 0.05).

CONCLUSIONSLNMM is detected by immunohistochemical anti-CK20 staining. The expression of nm23-H(1) and MMP(9) in primary stage Dukes B tumors was significantly associated with LNMM. The outcome in the LNMM patients with nm23-H(1) (-) and/or MMP(9) (+) were worse. Combining examination of CK20 for lymph nodes with expression of nm23-H(1) and MMP(9) for primary tumors is of important clinical significance for staging of Dukes, selection of adjuvant treatment and evaluation of prognosis in patients with colorectal cancer.

The aim of this study is to explore the tissue distribution of PEGylated puerarin in acute myocardial ischemia model rats. Healthy male SD rats were randomly divided into two groups (30 each). Both were given PEGylated puerarin at a dose of 488 mg x kg(-1). After 5 min of medication, one group was normal rats, another group with acute myocardial ischemia was established by peritoneal injection of 50 mg x kg(-1) isoprenaline. After administration, the animals were executed at 30, 60, 90, 120, 150 and 180 min, then heart, liver, spleen, lung, kidney were extracted. The content of puerarin in organ tissue was determined by HPLC. The results showed that the AUC of tissue distribution of PEGylated puerarin in normal rats was liver > kidney > heart ≈ spleen > lung > brain. While the AUC of tissue distribution of PEGylated puerarin in acute myocardial ischemia model rats was liver ≈ heart > kidney > lung ≈ spleen > brain. AUC(heart) of PEGylated puerarin in acute myocardial ischemia model rats was 1.7 times than that of the normal rats, and there was significant difference (P < 0.05). Thus, PEGylated puerarin had a good heart-targeting property in early myocardial infarction area, drugs could accumulate in the ischemic myocardium. It provided important information for further study and clinic use of PEGylated puerarin.

Diabetes mellitus is a common metabolic disease with a high and growing prevalence affecting 4% of the population worldwide, the development of safe and effective therapeutic drug is the major thrust for chemists and pharmacists. To search for active antidiabetic lead compound, we designed and synthesized some novel beta-amino ketone derivatives containing sulfamethoxazole moiety directly through Mannich reaction of sulfamethoxazole, 4-bromoacetophenone and some aromatic aldehydes catalyzed by concentrated hydogen chloride or iodine in the solution of ethanol at 24-40 degrees C with convenient operation, mild reaction condition and satisfactory yield (32%-90%). Their chemical structures were characterized by 1H NMR, 13C NMR, MS and HR-MS. Biological activity tests showed that, in the range of low concentration (5-10 microg x mL(-1)), these title compounds to a certain degree possess protein tyrosine phosphatase 1B (PTP1B) inhibitory activity and a-glucosidase inhibitory activity, moreover, some could activate peroxisome proliferator-activated receptor response element (PPRE) moderately. The PPRE agonist activities of seven compounds are almost 40% of that of Pioglitazone (the positive control), compound 12 shows the strongest activity (66.35%) among them. Thus, it was found that some of 4-(3-(4-bromophenyl)-3-oxo-1-arylpropylamino)-N-(5-methyl-isoxazol-3-yl) benzenesulfonamide containing sulfamethoxazole moiety exhibited antidiabetic activity for the first time.
