Belonging to the genetic engineering field in medicine, the invention discloses a construction scheme for artificially modified human adenovirus type 5 (Ad5), and specific application of a tumor-selective replicative adenovirus construct in tumor treatment. With the techniques of PCR (polymerase chain reaction) amplifying fixed point deletion, enzyme cutting, connection, cloning, homologous recombination, transfection, single cloning purification of adenovirus and the like, a recombinant adenovirus construct can be acquired. Acquisition of the construct is characterized in that: 27 bases are deleted in 2(CR2) region of E1A conserved sequence of Ad5 genome; 28530-29360nt in 6.7k/gp19k gene in E3 region are deleted, and meanwhile a fragment of full-length cDNA(1131bp) of HSV-TK (herpes simplex virus thymidine kinase) is inserted into the deletion region. The construct of the invention is a novel oncolytic adenovirus carrier with high tumor-selective replication capability. With the suicide gene of HSV-TK and dissolubility of tumor cells by oncolytic viruses, the dual killing effects have unique utility value in tumor biotherapy.

Disclosed is an anti-cancer medicament ent-kauran-19-al-17-oic acid which is prepared by the steps of, (1) disintegrating the aired round lichee stems, extracting with ethanol, condensing into extract, (2) extracting with chloroform, column chromatography, purging and column chromatography again, and purging to obtain the end product.

The invention relates to substituted-indanyl amide-type compounds as shown in the general formula I, pharmaceutically acceptable salt of the compounds and a preparation method and an application thereof. The invention also provides a pharmaceutical composition of the compounds. Through in vitro and in vivo anti-tumor effect research results and acute toxicity research results, the anti-tumor drug substituted-indanyl amide-type compounds have more excellent antitumor activity and safety, especially resisting imatinib drug-resistant tumors, and can be applied in curing tumors such as leukemia, gastrointestinal stromal tumor, lung cancer, colon cancer, ovarian cancer, kidney cancer and the like. Thus, the compounds have wide therapeutic window and have application value when used as an anti-tumor agent in the field of medicine.

The invention provides a Chinese traditional medicine compound prescription, and a preparation method and the purpose thereof, which mainly provides the Chinese traditional medicine compound prescription consisting of evodia, marsdenia tenacissima, climbing nightshade, oriental biter weed, Chinese fevervine, spatholobus stem, honey-suckle stem, wild grapevine, sargentg loryvine, Radix sophora flavescens, Paris Rhizome, licorice, etc. The preparation method comprisesthe following steps: step one, the alcohol reflux or the warm immersion abstraction of the evodia and the climbing nightshade, step two, the water extract-ethanol precipitation of gruffs and the rest medicinal materials, and step three, the blending of aqueous extract and ethanol extract. The invention provides the purposes of the compound prescription and the extract for the medicines of curing lung cancer, liver cancer, stomach cancer, rectal cancer, oophoroma, cervical carcinoma, prostatic cancer, bone cancer and other cancers, and simultaneously the invention also provides all administration forms including oral administration, rectum administration, intramuscular administration, vena administration, nasal cavity administration, vagina administration, subcutaneous administration, etc., and all preparation forms accepted by pellet, hard capsule, soft capsule, granula, oral liquid, syrup and pharmacy.

The present invention relates to an anticarcinogen prepared through extraction from mistletoe. The extraction process of mistletoe alkaloid includes the steps of: drying and crushing raw material, ethanol reflux extraction, reduced pressure recovering ethanol in extractive liquid, concentration to obtain extract, hydrochloric acid dissolution of alkaloid, still standing, extracting supernatant liquid, sucking filtering, adding dropwise concentrated ammonia water to free alkaloid, chloroform extraction, water washing chloroform liquid, drying with anhydrous sodium sulfate, recovering chloroform, and still standing to separate mistletoe alkaloid crystal. The medicine mistletoe alkaloid has obvious inhibiting effect on liver cancer, stomach cancer oesophagus cancer and mammary cancer, and has high anticancer activity, wide anticancer spectrum and less toxicity.

The invention relates to an anti-tumor small-molecule inhibitor with a brand-new skeleton structure and targeting PD1/PDL1 interaction discovered on the basis of a virtual screening strategy and application of the anti-tumor small-molecule inhibitor. The small-molecule inhibitor N-{4-[(4-chlorobenzyl) oxy] benzyl}-N-(4-pyridinzyl) amine provided by the invention has good affinity and good biological activity with PD-L1, and can activate the immune response of T cells by inhibiting the interaction of PD-1/PD-L1 at the cell and animal level, so as to effectively target and kill tumor cells and block the immune escape way of tumor cells. In addition, the small molecule inhibitor has no obvious toxic or side effect. Therefore, the small molecule inhibitor can be effectively used for treating cancer diseases, can be used for treating tumors such as melanoma, colon cancer, gastric cancer, breast cancer, liver cancer and lung cancer, has important clinical value and has a wide development prospect.

The present invention discloses an anticancer medicine. It is prepared from agrimony (agrimonia pilosa) and bearded scutellaria or added with ethyl alcohol and water extracts of sargassum and ganoderma, mixed them with auxilairy material and adopting conventional process of the Chinese medicine to obtain said invented product. Said anticancer medicine has the effect of supplementing vacuity, strengthening stomach, removing toxic material and softening hardness, and has good anticancer effect and broad anticance spectrum and has no clear toxic side reaction.

This invention relates to methylaminopterin derivatives with 4-amino structure modified, which inhibit effect of nitrogen monoxide synthetase and growth of tumors. They have wide anti-cancer spectrum and little toxic side effect so as to be used in preparation of medicines for tumors, cancers, arthritis and intestinal diseases as well as chemicals for birth control.

The invention belongs to the technical field of medicines, and relates to an HIF-2 alpha small-molecule inhibitor as well as a preparation method and an application thereof. The HIF-2alpha small-molecule inhibitor is a compound as shown in a structural general formula I and a stereoisomer, a pharmaceutically acceptable salt, a hydrate, a solvate or a prodrug thereof.
