ABSTRACT

Ionizing radiation causes the massive apoptosis of human tissue cells,leading to dysfunction of the gastrointestinal tract and hematopoietic system.Thus,high-efficiency,low-toxicity radiation protection drugs are urgently needed.Toll-like receptor agonists have been developed based on the anti-apoptotic mechanism of tumor cells in recent years,which exert their radioprotective effects by activating downstream pathways,mainly nuclear factor-κB.Here we elucidate several agonists of Toll-like receptors involved in radiation protection,with an attempt to inform the research and development of new radiation protection agents.

ABSTRACT

@#【Objective】To investigate the effect of Imatinib(Ima)on the inflammatory phenotype of RAW264.7 mac⁃ rophages induced by lipopolysaccharide(LPS).【Methods】RAW264.7 cells were treated by LPS(0.1 μg/mL)and/or Ima(1 μmol/L,5 μmol/L). The mRNA levels of IL-1β,IL-10,CCL2,iNOS,TNF-α and Arg1 in RAW264.7 cells were tested by Q-PCR. The iNOS protein level and the activation of NF-κB and MAPK signal pathways were detected by Western Blot. The protein levels of IL-1β,CCL2,IL-10 and TNF-α in cell supernatant were detected by ELISA. 【Results】Compared with the normal control group,the mRNA levels of IL-1β,CCL2,iNOS,TNF-α and IL-10 were significantly increased in RAW264.7 cells treated with LPS for 8 h(P < 0.001). In addition,the cell supernatant protein levels of IL-1β,IL-10,CCL2 as well as TNFα and the iNOS protein level were significantly increased in RAW264.7 cells stimulated by LPS for 24 h(P < 0.001). Moreover,the phosphorylation levels of p65,p38,ERK and AKT were enhanced in RAW264.7 cells after treatment with LPS for 24 h. Compared with LPS group,pretreatment with Ima decreased the mRNA and protein levels of IL-1β,CCL2,iNOS and TNF-α(P < 0.01,P < 0.001),but increased the mRNA and protein level of IL-10(P < 0.001). And this effect of Ima was dose-dependent. The phosphorylation levels of p65,p38, ERK and AKT were decreased in LPS+Ima group compared with that in LPS group. The functional status of RAW264.7 cells did not change significantly after treatment with Ima alone.【Conclusions】The effect of Imatinib to inhibit the inflammato⁃ ry phenotype of macrophage is related to retarding the overactivation of NF-κB and MAPK signaling pathways.

ABSTRACT

OBJECTIVE: To investigate the proportion of 8 kinds of ginsenoside to ginsenoside Rg1 in Panax ginseng and the regularity of growth year in Jilin province, and to provide reference for the identification of growth year. METHODS: The samples of garden ginseng, wild-cultivated ginseng and wild ginseng were collected from different growth years (3-30 years) in Jilin province. The contents of 8 ginsenoside (ginsenoside Rg1, Re, Rf, Rb1, Rc, Rb2, Rb3, Rd) in P. ginseng were determined by HPLC. The contents of saponins as well as the proportion of 8 kinds of ginsenoside to ginsenoside Rg1 were calculated; the relationship of the proportion with growth year was investigated. RESULTS: As the increase of growth year, the proportion of 8 kinds of ginsenosides in garden ginseng to ginsenoside Rg1 as well as that of ginsenoside Re, Rb1, Rc, Rd to ginsenoside Rg1 were decreased gradally (P<0.001); the proportion of ginsenoside Re to ginsenoside Rg1 in wild-cultivated ginseng decreased first and then increased(P<0.001); the proportion of 8 kinds of ginsenosides to ginsenoside Rg1 as well as the proportion of ginsenoside Re and Rb1 to ginsenoside Rg1 were increased gradually in wild ginseng (P<0.001); the proportion of ginsenoside Rf, Rb3 to ginsenoside Rg1 in garden ginseng, wild-cultivated ginseng and wild ginseng had no significant difference(P>0.05). CONCLUSIONS: Garden ginseng, wild-cultivated ginseng and wild ginseng contain 8 kinds of ginsenosides. The growth year can be predicted preliminarily according to the proportion of ginsenoside Rg1 and ginsenoside Re, Rb1 to ginsenoside Rg1.

ABSTRACT

Danshensu [3-(3, 4-dihydroxyphenyl) lactic acid, DSS], one of the significant cardioprotective components, is extracted from the root of Salvia miltiorrhiza. In the present study, an ester prodrug of Danshensu (DSS), palmitoyl Danshensu (PDSS), was synthesized with the aim to improve its oral bioavailability and prolong its half-life. The in vitro experiments were carried out to evaluate the physicochemical properties and stability of PDSS. Although the solubility of PDSS in water was only 0.055 mg·mL, its solubility in FaSSIF and FeSSIF reached 4.68 and 9.08 mg·mL, respectively. Octanol-water partition coefficient (log P) was increased from -2.48 of DSS to 1.90 of PDSS. PDSS was relatively stable in the aqueous solution in pH range from 5.6 to 7.4. Furthermore, the pharmacokinetics in rats was evaluated after oral administration of PDSS and DSS. AUC and t of PDSS were enhanced up to 9.8-fold and 2.2-fold, respectively, compared to that of DSS. C was 1.67 ± 0.11 μg·mL for PDSS and 0.81 ± 0.06 μg·mL for DSS. Thus, these results demonstrated that PDSS had much higher oral bioavailability and longer circulation time than its parent drug.
