The aim of this study is to evaluate anti-tumor activities and mechanism of a novel kinase inhibitor ZLJ213 which targeted Aurora A and vascular endothelial growth factor receptor (VEGFR) in vitro and in vivo against human colon cancer. Results showed that ZLJ213 inhibited cell proliferation and induced cell cycle arrest and apoptosis of HCT1 16 and SW48 cell lines. In HCT116-derived xenograft, ZLJ213 dosed at 100 mg · kg(-1) inhibited tumor growth by 73.24%. The IC50 of ZLJ213 on the expression of p-Aurora A was 0.258 µmol · L(-1) analyzed by ELISA. Under the concentration of 0.08 µmol · L(-1), ZLJ213 could inhibit the activities of Aurora A, Histone H3 and VEGFR of HCT116 and SW48 cell lines. Simultaneously, ZLJ213 induced activation of Caspase 3 and PARP cleavage. Above data suggested that ZLJ213 had the ability to inhibit cell proliferation and induce cell apoptosis both in vitro and in vivo in colon cancer, and down-regulate the expression of p-Aurora A and p-VEGFR. ZLJ213 might be a potential therapeutic agent against colon cancer.

A series of novel sorafenib analogues were designed and synthesized. The cytotoxic activities of these compounds were tested in four tumor cell lines. Some of the compounds showed potent antiproliferative activity against the tested cell lines with IC50 = 4-20 micromol x L(-1). Some compounds demonstrated competitive antiproliferative activities to sorafenib against tested cancer cell lines. Among them, compound 7c demonstrated significant inhibitory activities on ACHN, HCT116 and MDA-MB-231 cell lines with IC50 values of 9.01, 4.97, 6.61 micromol x L(-1), respectively.

OBJECTIVETo explore the correlation between Pi and Shen by observing the relationship between the metabolism of aristolochic acid (AA) and mRNA and protein expression levels of organic anion transporting polypeptide (oatp) superfamily member 2a1 and 2 b1 (oatp2al and oatp2bl) in renal, small intestinal, and large intestinal tissues of Pi deficiency syndrome (PDS) model rats.
METHODSTotally 46 Sprague-Dawley (SD) rats were randomly divided into four groups, i.e., the blank group (n = 12), the PDS group (n = 22), the AA-I group (n = 6), and the PDS AA-I group (n = 6). PDS model was established by subcutaneously injecting Reserpine at the daily dose of 5 mg/kg for 16 successive days. Carotid intubation was performed in 6 rats selected from the blank group and the PDS group. Pharmacokinetics of AA-I were detected at 5, 15, 30, 45, and 60 min after gastrogavage of AA-I. AA-I concentrations in renal, small intestinal, and large intestinal tissues of 10 rats selected from the PDS group were determined. Normal saline was administered to 6 rats selected from the PDS group and the blank group by gastrogavage. Renal, small intestinal, and large intestinal tissues were collected in the AA-I group and the PDS AA-I group at 60 min after gastrogavage of AA-I. mRNA and protein expression levels of oatp2a1 and oatp2b1 in each tissue were detected using real-time polymerase chain reaction (RT- PCR) and Western blot.
RESULTSCompared with the blank group, plasma concentrations of in vivo AA-I were obviously higher in the PDS group at 15, 30, 45, and 60 min after gastrogavage of AA-I with statistical difference (P < 0.05). Plasma concentrations of AA-I were obviously decreased at 60 min after gastrogavage of AA-I; AA-I concentrations in renal and large intestinal tissues were elevated; AA-I concentrations in small intestinal tissues were obviously reduced in the PDS group. There was no statistical difference in mRNA expression levels of oatp2a1 and oatp2b1 in the aforesaid three tissues of rats between the blank group and the PDS group. Compared with the blank group, mRNA expression levels of oatp2a1 and oatp2b1 decreased in small intestinal tissues of the AA-I group, and the mRNA expression level of oatp2a1 in large intestinal tissues significantly decreased (P < 0.05, P < 0.01). Compared with the PDS group, mRNA expression levels of oatp2a1 and oatp2b1 increased in renal tissues of the PDS AA-I group (P < 0.05); mRNA expression levels of oatp2b1 increased in large intestinal tissues of the PDS AA-I group (P < 0.05).
CONCLUSIONSThe difference in AA-I metabolism might be associated with changed expression levels of oatp2a1 and oatp2b1 in renal, small intestinal, and large intestinal tissues under Pi deficiency induced loss of transportation. Shen and Dachang played important roles in substance metabolism under Pi deficiency state, which proved Pi-Shen correlated in Chinese medical theories.

Curcumin has been reported to possess antitumor activity with low toxicity. However, the clinical application of curcumin has been significantly limited by its instability and poor metabolic property. In order to overcome these limitations and discover novel small molecules with potential antitumor activity, 29 curcumin mimics were synthesized, which were confirmed by 1H NMR and HR-MS, and their cytotoxic property was evaluated against five human cancer cell lines in vitro. Compounds 16, 18 and 19 exhibited good cytotoxic property, their IC50 value were even below 5 micromol x L(-1) to some cancer cell lines, 5-9 times better than curcumin.

Objective To investigate the clinical significance of flow cytometry (FCM) assay in following up of the minimal residual disease (MRD) used for predicting relapse and guiding chemotherapy. Methods The clinical data of 43 acute leukemia patients diagnosed by MIC were collected in our hospital from 2005 July to 2008 June.Bone marrow aspirates were collected from 43 patients with newly diagnosed acute leukemia after induction therapy and during constimulation therapy. The cells with leukemia associated with immunophenotype were investigated using FCM, as immunologic target of MRD. Results MRD were detected earlier in predicting the relapse than those of the traditional bone marrow cells morphology assay by an average of 4-6 months. The results of the MRD following up: MRD was negative at CR in 26 cases, 6 cases relapse, 20 cases of them were kept negative during following up. MRD was positive in 17 cases at CR, 9 cases of them were relapse. 4 cases after intensified chemotherapy the MRD became negative and kept egative for more than one year. The MRD of the 43 cases at CR were divided into 3 groups, MRD less than 1×10-4 group (A group) MRD between 5×10-3 and 1×10-4 group (B group) and MRD above 5×10-3 group(C group). By chi square test. There was no statistical significance between A group and B group, but there was tatistical significance between B group and C group (P=0.02). Conclusion The application of FCM in detecting MRD has important clinical significance in predicting relapse and guiding chemotherapy.
