Description
Technical field
The present invention relates to organic chemistry, particularly prodrug and pharmaceutical preparation.
Background technology
Voriconazole is a kind of triazole antifungal agent of wide spectrum
Its indication is as follows：Treatment Aspergillosis, the sexy dye of the microbial bad attack of beads to fluconazole resistant for the treatment（Including Candida krusei）, treat the severe infections being caused by Scedosporium and FusariumThis product should be primarily used to progressive in treatment immune deficient patientsThe infection of possible life-threatening.Voriconazole phosphate ester is the prodrug of voriconazole, voriconazole can be hydrolyzed to rapidly in vivo and onset, because voriconazole water solublity is minimum, in order to solubilized Voriconazole for Injection is using the method for hydroxypropylβ-cyclodextrin parcel, but which increase the incidence rate of side reaction.Hydroxypropylβ-cyclodextrin is a kind of new adjuvant occurring in recent years, because this adjuvant has preferable solubilization to multiple insoluble drugs, thus the domestic use to this adjuvant has the trend of quick increase, but up to the present we understand to its safety deeply.This adjuvant of document report has certain hemolytic, nephrotoxicity and carcinogenecity, and there is likely to be more serious toxic and side effects still not known to us, thus it is using more preferably prudent.Abroad only has the listing preparation of a few special indication（As treated the medicine of severe infection, tumor）Employ hydroxypropylβ-cyclodextrin, illustrate abroad also there is no enough assurance to its safety.In this case, the research that this kind of adjuvant should be continued deeper into and observation, expose its toxic and side effects that may be present further, and should not be used as a kind of adjuvant of routine and be widely used in injection.The untoward reaction of intravenous injection hydroxypropylβ-cyclodextrin mainly concentrates on nephrotoxicity and hemolytic, main relevant with the known impurities beta-schardinger dextrin-of this adjuvant, this impurity causes tubular distal cavity sample pathological changes first, subsequently huge lysosome and obvious acicular crystals occur in epidermis cell, now speculate that this crystalline solid is likely to be the complex of cyclodextrin and cholesterol or lipoprotein.And then the significance change of organelle occurs, the irreversible fracture of intercellular tight junction in the cell of such as mitochondrial swelling deformation, Golgi body and smooth endoplasmic reticulum basilar parts, and this result directly results in going down or even losing of renal function.Voriconazole phosphate ester is to reduce the effective means that these side reactions occur, and Chinese patent is referred to voriconazole phosphate ester and preparation method thereof.
Phosphate ester is widely used in preparing the water miscible prodrug for intravenous administration.Its prodrug carries out esterification by the hydroxyl of voriconazole with phosphoric acid and is produced.In vivo, its fast hydrolyzing and present the clinical effect being equal to voriconazole.The phosphate ester esterification of voriconazole makes this compound in pH
There is in the aqueous solution of 4-12 high dissolubility.With in the mycotic patient in deep position needing high dose antifungal, carry out multiple Concomitant medications and complementary therapy, such as fluid infusion.But, in concurrently serious obscure disease, particularly in the patient of heart failure, respiratory failure or ascites, fluid infusion may be confined to adjust the balance of cylinder water content and electrolyte.Compared with voriconazole, voriconazole derivate is relatively easy for deep position funguses patient, because it can pass through bolus administration, thus significantly reducing volume load.
The serious effectively treatment limiting fungal infection of daily maintenance metering of voriconazole.This administration schedule leads to the higher workload of clinical staff, and importantly, the patient compliance of difference, therefore increased the probability giving suboptimal dose, ultimately result in appearance refractory fungal strain.When the compliance of patient is problem, the dosage form of long-acting dosage is one and possible solution, wherein single-dose leads to sustained release drugs in in the period of extending.This dosage form simplifies the dosage regimen that patient's needs are observed, the probability of the non-compliance occurring when therefore reducing using more accurate dosage regimen.One of these dosage forms are reservoirs
(depot) preparation, it can be with various administrations, including intramuscular injection.Prepare depot dosage injection, slowly absorbed the drug from medicine-feeding part with providing, generally can keep treatment level a few days or several weeks in entire patient every time.
Depot dosage injection has cost.The volume of injection is bigger, injection more pain；It is therefore desirable to as far as possible by the volume minimization of injection.
It is an object of the present invention to provide voriconazole derivate and preparation, its interior this medicine of delivery during duration under the concentration effective for treatment mammal (including people).These voriconazole forms and preparation must be safe, that is, have the side effect of minimum and have suitable pharmacokinetics distribution.
It is an object of the present invention to provide voriconazole derivate and preparation, it can improve one or more following pharmacokinetic parameters with respect to currently available preparation：Longer half-life, increase volume of distribution, extend drug release, the acting duration of lasting plasma concentration or longer.
It is an object of the present invention to provide for voriconazole derivate and the preparation of Clopidogrel when compared with currently available dosage form.
It is an object of the present invention to provide the chemically stable derivant of voriconazole.It is a further object to provide the chemically stable preparation of voriconazole.It is a still further object of the present invention to provide the soluble derivative of voriconazole.
It is an object of the invention to the agent number of the voriconazole that will give minimizes.It is an object of the present invention to provide allowing voriconazole derivate or the preparation of bolus injection.Another object of the present invention is the reservoir providing voriconazole in patients.
It is an object of the present invention to provide avoiding the voriconazole injectable formulation of the proper volume of pain administration.
It is an object of the present invention to provide voriconazole derivate and the preparation of refractory fungal strain appearance can be reduced.
It is an object of the present invention to provide voriconazole derivate and the preparation of intracellular voriconazole concentration can be increased.
Content of the invention
Inventor has surprisingly observed that some voriconazole derivates with the dissolubility distribution attracting people's attention present valuable high-dissolvability in some lipophilic solvents.Particularly, some voriconazole derivates of the present invention are highly suitable for lipid formulation and injectable depot formulations.These preparations even all present effective plasma concentration upon administration in 2 months.In addition, the present invention reaches this finally required increase drug load in the way of to patient and all convenient administration of clinical staff and extends delivery.
