In the present study, a new compound named 17-(6-cinnamamido-hexylamino-)-17-demethoxygeldanamycin (CDG) was obtained by introducing the cinnamic acid (CA) group into the 17-site of geldanamycin (GDM). The anti-cancer effects of CDG in vitro and in vivo were evaluated. MTT assay was used to examine the inhibitory effect of CDG on the proliferation of MCF-7, HepG2, H460 and SW1990 cells. Immunofluorescent staining flow cytometry combined with Annexin V-FITC/PI staining were used to detect apoptotic cells. Transwell assay was used to analyze the effect of CDG on cell invasion and migration ability. Western blotting was used to detect the expression levels of RAF-1, EGFR, AKT, CDK4 and HER-2 of MCF-7, HepG2 and H460 cells. The toxicities of CDG and GDM were evaluated in mice. Using the subcutaneously transplanted MCF-7 xenograft in nude mice, inhibitory effect was evaluated in vivo. The results showed that CDG inhibited the proliferation of cancer cells (IC50: 13.6-67.4 microg.mL-1). After exposure to CDG for 48 h, most cells presented typical morphologic changes of apoptosis such as chromatin condensation or shrunken nucleus. The rates of apoptosis of MCF-7, HepG2, H460 and SW1990 cells incubated with 10 microg.mL-1 CDG were 23.16%, 27.55%, 22.21%, 20.47%, respectively. A dose-dependent reduction of migration of four cell lines was found after exposure to CDG. The decreased levels of RAF-1, EGFR, AKT, CDK4 and HER-2 showed that CDG possessed HSP90 inhibitory effect. The result of animal toxicity test on the mice suggested that CDG had lower toxicity than GDM. Meanwhile, CDG inhibited the growth of MCF-7 xenografts of athymic mice.

In recent years, the study of autophagy in spinal cord injury (SCI) gradually becomes the hot spot. However, the function of autophagy in the injured spinal cord is still controversial. In order to further understand the role of autophagy after SCI, we summarized the activation of autophagy, autophagic cell death, the relationship between autophagy and apoptosis, the function of autophagy in promoting the molecular metabolism and the role of autophagy after spinal cord injury. We concluded that the role of autophagy after SCI is a double-edged sword. Upregulating the level of autophagy appropriately can promote damaged proteins metabolism and inhibit apoptosis. However, excessive activation of antophagy may induce autophagic cell dealth. So we consider that the proper regulation of autophagy will be a new target in the treatment of SCI.

Objective To investigate the effect of Shensong Yangxin capsule on cardiac remodelling of myocardial infarction mouse model and the possible molecular mechanisms. Methods Adult male C57BL/6J mice were divided into sham operation group(n=10), model control group(n=20)and Shensong Yangxin group(n=20)according to random number table. Left anterior descending branch of coronary artery was ligated to establish myocardic infarction model in the model control group and Shensong Yangxin group. From the 2nd day after the surgery, Shensong Yangxin ( 400 mg . kg-1 ) was intragastrically administered, and the death rate of the mice was observed.Four weeks after the surgery, echocardiography was used to measure the cardiac function;myocardiac infarction area was detected by pathological staining;the expression levels of cardiac remodelling markers and extracellular matrix proteins were detected by RT-PCR. The possible molecular mechanisms were screened by Western blotting. Results As compared with the model control group, Shensong Yangxin significantly reduced the mortality after myocardial infarction in mice(P<0.05), as well as the myocardial infarct size(P<0.05).The mRNA expression levels of cardiac remodelling markers ANP, BNP, and β-MHC and the extracellular matrix proteins(collagenⅠ, collagen Ⅲ, CTGF, TGFβ) decreased significantly in the Shensong Yangxin group as compared with the model control group. Western blotting showed that Shensong Yangxin significantly decreased activation of smad3, and reduced expression level of smad4. Conclusion Shensong Yangxin attenuates cardiac remodelling after myocardial infarction and the mechanism may be related with blockage of smad signaling pathway.
