The present invention relates to the field of pharmacochemistry. Disclosed are fluorinated and azido-substituted pyrimidine nucleoside derivatives, and preparation methods and uses thereof. The structural formula is as shown (I). These compounds can be used for preparing medicaments for treating diseases such as tumors and viral infections, and can be used separately or in combination with other medicaments. The compounds also have effective activity against diseases such as tumors and viral infections, while having few side effects, and thus have potential application value.

Dysregulation of the nucleo-cytoplasmic transport of proteins plays an important role in carcinogenesis. The nuclear export of proteins depends on the activity of transport proteins, exportins. Exportins belong to the karyopherin β superfamily. Exportin-1 (XPO1), also known as chromosomal region maintenance 1 (CRM1), mediates transport of around 220 proteins. In this review, we summarized the development of a new class of antitumor drugs, collectively known as selective inhibitors of nuclear export (SINE). KPT-330 (selinexor) as an oral agent is showing activities in early clinical trials in both solid tumors and hematological malignancies.

Single-walled carbon nanotubes (SWNT) are poorly soluble in water, so their applications are limited. Therefore, aqueous solutions of SWNT, designed by noncovalent functionalization and without toxicity, are required for biomedical applications. In this study, we conjugated docetaxel with SWNT via π-π accumulation and used a surfactant to functionalize SWNT noncovalently. The SWNT were then conjugated with docetaxel (DTX-SWNT) and linked with NGR (Asn-Gly-Arg) peptide, which targets tumor angiogenesis, to obtain a water-soluble and tumor-targeting SWNT-NGR-DTX drug delivery system. SWNT-NGR-DTX showed higher efficacy than docetaxel in suppressing tumor growth in a cultured PC3 cell line in vitro and in a murine S180 cancer model. Tumor volumes in the S180 mouse model decreased considerably under near-infrared radiation compared with the control group. The SWNT-NGR-DTX drug delivery system may be promising for high treatment efficacy with minimal side effects in future cancer therapy.

Analysis of the efficacy and timing of plasma exchange (PE) in the treatment of acute fatty liver of pregnancy (AFLP). The clinical data of 39 cases of AFLP treated with PE from September 2004 to March 2011 include symptoms, physical signs, adverse effects, and all relevant laboratory test results before and after PE. (1) Adverse reactions during PE were generally mild and tolerable, and no patients discontinued treatment due to adverse events; symptoms, physical signs, and liver and kidney functions improved significantly after PE (P<0.05); (2) of the 39 cases treated, 37 were cured, 2 died, with a cure rate of 94.87%; (3) of the 37 cases cured, the sooner a patient received PE the faster the recovery and the fewer number of PEs needed for a complete recovery (P<0.01). Treatment of AFLP by PE is safe and effective, and timely application of PE in the early phase of the disease can effectively halt and reverse the progression of AFLP.

The international community, under the auspices of the World Health Organization, developed the landmark Framework Convention on Tobacco Control (FCTC) to curb the global tobacco epidemic. As an internationally binding convention about global best practices on tobacco control, the FCTC has become an overriding source of policy transfer for developing countries in the fight against smoking. However, since its ratification of the first global norm over tobacco governance and against the grim background of the widespread tobacco-induced public health devastation within its borders, China has failed to genuinely pursue FCTC policies because of domestic political and social factors. The empirical findings of this article point to the dominance of political-social dynamics for China's nontransfer of FCTC policies, arguing that the government's GDPism, its sovereignty-first mentality, and hostility to NGOs as well as widespread social acceptability of tobacco consumption and high smoking prevalence are fundamental causes of China's nontransfer of FCTC policies. The article explicates how these variables correspond to FCTC policies in an analytic framework of policy transfer. © 2014 by Duke University Press.

An efficient, mild, and generally applicable protocol for copper-mediated oxidative decarboxylative coupling of arylpropiolic acids with dialkyl H-phosphonates in water has been developed. Note that the reaction could proceed smoothly under air at relatively low temperature (60 C), and the addition of isopropanol could successfully suppress the decomposition of dialkyl H-phosphonates in water. © 2014 American Chemical Society.

Disclosed is a use of C15-substituted andrographolide derivatives in preparation of anti-hepatitis B virus medicaments. In the present invention, the HepG2.2.15 cells are used to measure the amount of the hepatitis B virus surface antigen (HBsAg) secretion in the supernatant of the culture; the duck hepatitis B virus (DHBV) is used to infect the model and the DHBV-DNA level in serum is measured, and the pathological change in hepatic tissue is observed. A number of andrographolide derivative compounds are screened, compounds having a good anti-HBV effect are preferred, which has a structure represented by general formula 1 set forth herein. Due to high anti-HBV activity and low toxicity, as well as good protection against hepatic injury, the compounds can be used as the active ingredient for preparing anti-HBV medicaments, thereby providing a new pharmaceutical way for treatment of hepatitis, and broadening the range of clinical medicines.

Disclosed is use of andrographolide derivative as shown by general formula 1 in manufacture of medicaments for anti-hepatitis C virus, and preventing and treating immunological liver damage caused by virus infection and different chemical liver damage.

The present invention relates to the preparation of anti-tumor drugs with andrographolide derivatives, which belongs to the field of pharmaceutical technology, and involves 15-benzylidene substituted derivatives of 14-deoxy-11,12-didehydro-andrographolide and their 3,19-ester derivatives. Proved by the experiments, these compounds significantly inhibited the colony formation and migration ability of various cancer cells, and also inhibited the migration ability of vascular endothelial cells in vitro. The compounds of this invention significantly inhibited the tumor growth, invasion, metastasis and angiogenesis on mouse xenograft models, and inhibited the experimental lung metastasis of B16-F10 malignant melanoma cells. Therefore, this class of compounds could be used as the active ingredients for the preparation of antineoplastic drugs, which are of efficiency and low-toxicity. Thereby it has potential to expand the selectable range of clinical drug and is of high significance to make full use of the plant resources of Andrographis paniculata.
