Description
(1) technical field
The present invention relates to a kind of anti-cancer composition that contains neovascularization inhibitor and/or alkylating agent, belong to technical field of pharmaceuticals.Particularly, this invention relates to a kind ofly can be released to the partial slow releasing preparation of entity tumor with neovascularization inhibitor and/or alkylating agent are stable, is mainly sustained-release implant and slow releasing injection, can prolong drug release time, and can increase the sensitivity of medicine.
(2) background technology
Chemotherapeutics topical application, particularly local sustained release have become the research direction and the focus of current entity tumor chemotherapy.Referring to (Chinese patent application numbers 200510042234.3,03148624.X, 200510042236.2,96116041.1,97107078.4,200510042260.6,200510042261.0,200510042262.5,200510042263.X; U.S. Pat 5651986, RE37410).
Yet existing slow-release auxiliary material above-mentioned and that other pharmaceutical preparation is used causes the prominent of medicine to release or unbalanced release when release more or less.The release medicine that has is slow excessively, is not enough to obtain in the part active drug concentration, thereby effective kill tumor cell; The release that has is too fast, often causes prominent releasing, and causes general toxic reaction as conventional injection easily.
Therefore, research and development can discharge in the specific time different pharmaceutical with stable or constant amount and speed just becomes present problem demanding prompt solution.
(3) summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of anticancer medicine slow-release preparation containing that contains neovascularization inhibitor and/or alkylating agent is provided, particularly, is a kind of slow releasing injection or sustained-release implant that contains neovascularization inhibitor and/or alkylating agent.Neovascularization inhibitor and/or the stable partial slow releasing preparation of entity tumor that is released to of alkylating agent can prolong drug can be able to be kept higher drug level, and can increase the sensitivity of medicine release time.
The present invention finds to have the composition of active anticancer, is not the slow release effect that all slow-release auxiliary material all can reach effective release.Pharmaceutic adjuvant have hundreds of more than, pharmaceutic adjuvant with slow releasing function, particularly the pharmaceutic adjuvant that different pharmaceutical slowly can be discharged in the regular hour in human body or animal body must could obtain through a large amount of creationary experiments, specific slow-release auxiliary material and can need be passed through a large amount of creative works by the selection of the combination of slow releasing pharmaceutical and could determine.Discharged and be not enough to obtain active drug concentration slowly, thereby effective kill tumor cell; Cause prominent releasing if discharge too fast meeting, then cause general toxic reaction easily, as polifeprosan (A.J.Domb etc., Biomaterials (1995), 16 (14): 1069-1072; Wenbin Dang etc., Journal of Controlled Release (1996), 42:83-92; Eric P.Sipos etc., Cancer Chemother Pharmacol (1997), 39:383-389; Lawrence K.Fung etc., CancerResearch (1998), 58:672-684).The data of release characteristics need could obtain through a large amount of creationary experiments in inside and outside in the related data, particularly animal body, are not just can determine to have unobviousness through limited experiment.

In the slow releasing injection, drug sustained release system can be made into microsphere, sub-micro ball, microemulsion, nanosphere, granule or spherical piller, makes the injection use then with after the injection solvent mixes.In various slow releasing injection, serve as preferred with the suspension type slow releasing injection, the suspension type slow releasing injection is the preparation that the drug sustained release system that will contain anticancer component is suspended in gained in the injection, used slow-release auxiliary material is a kind of or its combination in the above-mentioned slow-release auxiliary material, and used solvent is common solvent or the special solvent that contains suspending agent.Common solvent is, but is not limited to the buffer that distilled water, water for injection, physiology are prepared towards liquid, dehydrated alcohol or various salt.The purpose of suspending agent is the pastille microsphere that effectively suspends, thereby is beneficial to the usefulness of injection.Be convenient injection, the viscosity of suspending agent is 100cp-3000cp (20 ℃-30 ℃ time), preferred 1000cp-3000cp (20 ℃-30 ℃ time), most preferably 1500cp-3000cp (20 ℃-30 ℃ time).Suspending agent is selected from one of sodium carboxymethyl cellulose, (iodine) glycerol, simethicone, propylene glycol, carbomer, mannitol, sorbitol, surfactant, soil temperature 20, soil temperature 40 and soil temperature 80 or its combination.
The content of suspending agent in common solvent is decided because of its characteristic, can be 0.1-30% and decides because of concrete condition.Consisting of of preferred suspending agent:
A) 0.5-5% sodium carboxymethyl cellulose+0.1-0.5% soil temperature 80; Or
B) 5-20% mannitol+0.1-0.5% soil temperature 80; Or
C) 0.5-5% sodium carboxymethyl cellulose+5-20% sorbitol+0.1-0.5% soil temperature 80.
The kind of solvent is then depended in the preparation of solvent, and common solvent has commercially available, also can make by oneself, and as distilled water, water for injection, physiology buffer towards liquid, dehydrated alcohol or the preparation of various salt, but must be in strict accordance with related standards.Special solvent need be considered the kind of suspending agent and the medicine that composition, solvent suspended, composition, character and the requirement thereof of sustained-release micro-spheres (or microcapsule) and the preparation method of injection, as sodium carboxymethyl cellulose (1.5%)+mannitol and/or sorbitol (15%) and/or Tween 80 (0.1%) are dissolved in the normal saline mutually deserved solvent, viscosity is at 10cp-650cp (20 ℃-30 ℃ time).
The present invention finds to influence medicine and/or sustained-release micro-spheres suspends and/or the key factor of injection is the viscosity of solvent, and viscosity is big more, and suspension effect is good more, and syringeability is strong more.This unexpected one of main index characteristic of the present invention of finding to have constituted.The viscosity of solvent depends on the viscosity of suspending agent, and the viscosity of suspending agent is 100cp-3000cp (20 ℃-30 ℃ time), preferred 1000cp-3000cp (20 ℃-30 ℃ time), most preferably 1500cp-3000cp (20 ℃-30 ℃ time).According to the viscosity of the prepared solvent of this condition is 10cp-650cp (20 ℃-30 ℃ time), preferred 20cp-650cp (20 ℃-30 ℃ time), most preferably 60cp-650cp (20 ℃-30 ℃ time).
The preparation of injection has several different methods, and a kind of is that the sustained-release microparticle (A) of suspending agent for " 0 " directly mixed in special solvent, obtains corresponding sustained-release microparticle injection; Another kind is that suspending agent is not mixed in special solvent or common solvent for the sustained-release microparticle (A) of " 0 ", obtains corresponding sustained-release microparticle injection; Another is that sustained-release microparticle (A) is mixed in common solvent, adds the suspending agent mixing then, obtains corresponding sustained-release microparticle injection.Except, also can earlier sustained-release microparticle (A) be mixed and in special solvent, make corresponding suspension, with the moisture in ways such as the vacuum drying removal suspension, special solvent of reuse or common solvent suspendible obtain corresponding sustained-release microparticle injection afterwards then.Above method just is illustrative rather than definitive thereof the present invention.It should be noted that suspended drug or sustained-release micro-spheres (or microcapsule) concentration in injection decide because of specifically needing, can be, but be not limited to, 10-400mg/ml, but be preferably with 30-300mg/ml, with 50-200mg/ml most preferably.The viscosity of injection is 50cp-1000cp (20 ℃-30 ℃ time), preferred 100cp-1000cp (20 ℃-30 ℃ time), most preferably 200cp-650cp (20 ℃-30 ℃ time).This viscosity is applicable to 18-22 injection needle and special bigger (to 3 millimeters) injection needle of internal diameter.
