A method of preparing and using a sterile non-toxic pyrogen-free cold extract from the leaves of Nerium oleander as a supplementary medication to cancer chemo-, hormon and/or radiotherapy to restore and/or ameliorate the immune system of the patient and/or to decrease side effects and increase the antitumor effects of radiotherapy and chemotherapeutics, particularly when used in combination with taxol, adriamycin, cisplatin, 5-fluoro-uracil, alimta, cyclophosphamide, mitomycin-C, navelbine, taxotere and topotecan, respectively, and its use in the manufacture of a medicament for the treatment of one or more cancers of bladder, kidney, liver, ovary, pancreas, testicle, uterus, and vagina as well as pleuramesotheliomas and Hodgkin's lymphomas.

Current approaches for treating cancer are limited, in part, by the inability of drugs to affect the poorly vascularized regions of tumors. We have found that spores of anaerobic bacteria in combination with agents which interact with microtubules can cause the destruction of both the vascular and avascular compartments of tumors. Two classes of microtubule inhibitors were found to exert markedly different effects. Some agents that inhibited microtubule synthesis, such as vinorelbine, caused rapid, massive hemorrhagic necrosis when used in combination with spores. In contrast, agents that stabilized microtubules, such as the taxane docetaxel, resulted in slow tumor regressions that killed most neoplastic cells. Remaining cells in the poorly perfused regions of tumors could be eradicated by sponzlated bacteria. Mechanistic studies showed that the microtubule destabilizers, but not the microtubule stabilizers, radically reduced blood flow to tumors, thereby enlarging the hypoxic niche in which spores could germinate. A single intravenous injection of spores plus selected microtubule-interacting agents was able to cause regressions of several tumors in the absence of excessive toxicity.

The invention discloses a DQA-PEG 2000-DSPE (Dequalinium Chloride-Polyethylene Glycol-Distearoyl Phosphatidyl Ethanolamine) conjugated compound and resveratrol liposome modified thereby. The structural formula of the compound is shown by a formula I. In terms of composition, the resveratrol liposome comprises resveratrol and a fat material, wherein the mass ratio of the resveratrol to the fat material is (1:20)-(1:40); and the fat material consists of egg yolk lecithin, cholesterol and the compound shown by the formula I in the molar ratio of (63-67):(18-22):(2-4.35) in sequence.

The invention provides nucleic acids, peptides, and antibodies for use in applications including diagnosis and therapy. The peptides target lung cancer and were identified by phage display. Targeting phage PC5-2 and synthetic peptide SP5-2 were both able to recognize human pulmonary tumor specimens from lung cancer patients. In SCID mice bearing NSCLC xenografts, the targeting phage was able to target tumor masses specifically. When the peptide was coupled to liposomes containing the anti-cancer drugs vinorelbine or doxorubicin, the efficacy of these drugs against human lung cancer xenografts was improved, the survival rate increased, and the drug toxicity was reduced.

The invention relates to a composite of an artemisinin derivative and vinorelbine in the technical field of pharmaceuticals and the application thereof; wherein, the ratio of the artemisinin derivative (including dihydroartemisinin or artesunate) and the vinorelbine is 1:500 to 500:1. The composite can be applied to preparing antineoplastics and made into the dosage forms of injection administration and oral administration by adding pharmaceutically acceptable adjuvant carriers. The two effective components (the artemisinin derivative and the vinorelbine) of the composite not only have obvious synergistic effect and but also can be cooperatively applied so as to reduce the amount of the vinorelbine and lower the production cost. By adding the pharmaceutically acceptable adjuvant carriers to prepare the dosage forms of injection administration and oral administration, the composite can be applied to the anti-tumor field.

The invention discloses a preparation method of vinorelbine.
