Description
Technical field
The present invention relates to biomedicine field, in particular, relate to a kind of antineoplastic drug carrier and using method thereof.
Background technology
Cancer is one of major disease affecting human health, and according to the investigation report display that World Health Organization (WHO) delivers in February, 2013, within 2008, the global number dying from cancer reaches 7,600,000, about has 13,000,000 newly-increased cancer patients every year.At present, cytotoxic drug has been widely used in the chemotherapy of cancer, but these medicines to the healthy cell of cancerous cell and human body exist non-specific, make it while killing and wounding cancerous cell, also have impact on normal body function.Therefore, improve local application's concentration, reducing general toxic reaction is the problem that oncotherapy urgently solves.Exploitation safety non-toxic, there is tumour-specific and can the tumor delivery system of high-efficient carrier antitumor drug imperative.In recent years, it is found that nano-medicament carrier can utilize the dimensional effect of its uniqueness, interfacial effect and macro quanta tunnel effect to strengthen the antitumous effect of medicine, obviously reduce drug-induced toxic and side effects.Such as, Li Yaping (ACS Nano [J], 7 (7): 5858 ~ 5869) has the pipe/polyhenylethylene nano drug-loading system of pH and time-response by building, simultaneously load amycin and disulfiram, work in coordination with and inhibit tumor cell proliferation, finally reverse tumor multi-medicine drug-resistant; Zeyu Xiao etc. devises the self assembly gold nanorods that can respond near infrared light, it can transport chemotherapeutics to specific tumors position, and optionally discharge medicine by the change of response external light, produce heat simultaneously and realize thermochemotherapy collaborative raising antitumor curative effect (Angewandte Chemie [J], 2012,51:11853 – 11857).Shi Jinjin etc. devise Fullerene-nanogold composite material, and to be applied in the neoplasm in situ degree of depth photo-thermal therapy radio frequency or microfiltration irradiates in medicine (China Patent No.: CN201310260339).But, in clinical conversion aspect, if nano medicament carrying system cannot be excreted by usual channel, harmful accumulation will be caused in vivo, have a strong impact on body health.Therefore, the safety of nanoscale medicine delivery system is the problem that people pay close attention to most all the time.Protein nano particle, as the outstanding representative of biocompatibility, is decomposed by homergy in vivo, and nanoparticle surface have many can adorned group, being conducive to the functionalization of nanoparticle, is desirable pharmaceutical carrier.Sungho Bae connects TRAIL and transferrins by the serum albumin nanoparticle surface load amycin people, obviously can suppress the propagation of HCT116, adriamycin-resistant MCF-7 and CAPAN-1 tumor cell, (the Biomaterials [J] on the tumor locus of HCT116 xenograft mouse and medicine can concentrate, 2012,33:1536-1546).Fa-Ming Chen constructs the glucosan-gelatin Nano capsule controlled release system of thermo-responsive, this Nano capsule utilizes and is connected on surperficial N-isopropylacrylamide to the sensitivity of temperature to discharge medicine (Biomaterials [J], 2013,34:6515-6527).The design of these biodegradability nanoprotein pharmaceutical carriers, can carry out the modification of physicochemical property, overcome antitumor drug hydrophilic poor, be difficult to enter the problems such as cell membrane to conventional tumour medicine; Meanwhile, by the finishing of antagonism nanoprotein pharmaceutical carrier, the functions such as antitumor drug targeting, spike, Synergistic treatment can be given, greatly improve the medical value of antitumor drug.
Phycobniliprotein is the water-soluble compound combined by multiple proteins, and be combined with covalent bond as chromophoric photopigment of catching, be mainly present in blue bacterium and some algae, comprise in red algae, hidden algae, Lycoperdon polymorphum Vitt algae and minority dinoflagellate.Its major function is caught as photosynthetic photopigment complex of catching and transmit light energy, then carries out photosynthesis with chlorophyll.Phycobniliprotein is mainly divided into four classes, that is: phycocyanin, allophycocyanin, phycoerythrin, phycoerythrocyanin (pec).Phycobniliprotein because of the fluorescent characteristic of its uniqueness be desirable fluorescent marker.In addition, phycobniliprotein has the several functions such as antioxidation, anti-inflammatory, defying age, antiviral, antiallergic, enhancing immunity, Tumor suppression, becomes the focus of people's Recent study.Caroline Costa Moraes etc. obtain the phycocyanin of analytical pure rank by a step chromatographic analysis, ion-exchange chromatography and intermediate processing, the method is simple, not only simplifies extraction step, and improves the purity of phycocyanin.(Bioresource technology[J],2009,100:5312–5317)。Juen-Haur Hwang etc. find that phycocyanin can treat tinnitus disease by suppressing the expression of NR2B and short inflammation gene expression, show its significant anti-inflammatory effect (Plos one [J], 8 (3): e58215).The allophycocyanin of colibacillary maltose-binding protein with cyanophyceae merges by Lin Liping etc. mutually, find that this recombinant allophycocyanin obviously can suppress Hepatocarcinoma Proliferation, have simultaneously and improve T cell immunologic function, promote T cell propagation, increase the immunostimulant feature (China Patent No.: CN1771925A) of cytokine IL-2 and γ-IFN generation.Cao Minjie etc. have invented the anti-soybean trypsin inhibitor antibody of a kind of phycoerythrin labelling, and this detection method has higher susceptiveness, simplicity, safety (China Patent No.: CN103087197A) than chemoluminescence method.The enzymatic hydrolysate that our seminar has set forth phycocyanin in the enzymatic hydrolysate and application patent thereof of Spirulina phycocyanin has effect of obvious antioxidation, scavenging free radicals, individual freedom base level can be reduced, prevention free radical disease (China Patent No.: CN101928743A).Be a kind of safe, nontoxic and have the biomacromolecule of good physiologically active based on phycobniliprotein, therefore its application in antineoplastic drug carrier has bright prospect.
Therefore, improve local application's concentration, reducing general toxic reaction is the problem that oncotherapy urgently solves.Exploitation safety non-toxic, there is tumour-specific and can the tumor delivery system of high-efficient carrier antitumor drug imperative.
