Description
Technical field
The present invention relates to pharmaceutical chemistry and crystallization processes technical field, and in particular, to calcifediol and vitamin D3's
Eutectic and preparation method and application.
Background technology
When two kinds and more than drug in combined clinical in use, can generally select exploitation into compound to improve compliance.
But since two or more active constituents (active pharmaceutical ingredient, API) are objects in compound medicine
Reason mixing, brings various problems:(a) the quality control standard problem of APIs.Although two or more of compound medicine
API is mixed in a certain ratio, but the reproducibility of its content standard is poor;Because being physical mixed, the X- of different compounds
The response of ray powder diffraction has difference, can not even more establish crystal form standard.(b) in production process APIs dispersion problem.
APIs contained by the drug products of per unit dose is only milligram even microgram rank, is difficult the ratio of control API in production process.
(c) storage problem of bulk pharmaceutical chemicals.Its stability of the active constituent of physical mixed is more more unstable than single component.It is and logical hypereutectic
Two or more API are prepared into supermolecule by method by weak interaction, can well solve current compound medicine band
The problem of coming.And drug-drug eutectic may have higher dissolution rate and bioavilability than physical mixed.
Drug cocrystallization refers to active constituents of medicine and other physiologically acceptable ligand (Co-crystal Co-
Former, CCF), such as acid, alkali, salt, non-ionic compound molecule are with hydrogen bond, pi-pi accumulation effect, Van der Waals force and other are non-
Covalent bond is connected and is incorporated in same lattice.Wherein API and CCF is solid at room temperature, and exists between each component and fix
Stoichiometric ratio.The formation of cocrystallization does not need to generate new covalent bond between API and CCF or molecule is destroyed,
Self assembly after only binary or multicomponent mixture rearrange.The advantage of cocrystallization is that host molecule API can be not only acid
Property or alkali molecules or non-ionized molecules;And the selection of CCF is also very much, including food additives, preservative, medicine
With auxiliary material, minerals, vitamin, amino acid, it might even be possible to be other API.Drug formed cocrystallization after pharmacological action not by
It influences, but physicochemical property is improved.By forming cocrystallization, its crystal form on the one hand can be greatly enriched, on the other hand
Its physico-chemical property and clinical efficacy can be improved.
Calcifediol (Calcifediol), chemistry are entitled:(5Z, 7E) -9,10- open loops cholesteric -5,7,10 (19)-triolefin -
3 β, 25- glycol, molecular formula C27H44O2, water (2.2ug/mL) is practically insoluble in, is soluble in organic solvent.Its monohydrate is
White crystalline powder, structural formula are as follows:
Vitamin D3(Vitamin D3), chemistry is entitled:9,10- open loop cholesterics -5,7,10 (19)-triolefin -3- alcohol, molecule
Formula is C27H44O.Structure is as follows:
Vitamin D is a kind of indispensable liposoluble vitamin of human body, after vitamin D enters in vivo, first passes around dimension
Raw element binding protein combines, and is transported to liver, under the action of CYP2R1 enzymes, is converted into calcifediol.Calcifediol is dimension life
The main storage forms of plain D in vivo, and can be detected in blood plasma, so calcifediol level is used for evaluating in blood plasma
Whether be deficient in vitamin D in vivo.Calcifediol is further metabolized in kidney, curing three of the generation with maximum bioactivity
Alcohol, and be combined with vitamin D receptor, it is transported to each target organ.Calcitriol and parathyroid hormone, calcitonin together,
The calcium phosphorus balance of blood plasma is adjusted, prevents rickets and osteomalacia.Vitamin D activities ingredient can also increase bone density, drop
The effects that low cardiovascular and cerebrovascular risk.
At present often by calcifediol and vitamin D in Clinical practice3Combination, can quickly and significantly improve blood plasma
The level of middle calcifediol achievees the purpose that improve internal vitamin D level to treat osteoporosis.But various rule in use
The vitamin D of lattice3With calcifediol it is difficult to which Proper Match uses, and patient's poor compliance.
Present inventor is directed to clinical calcifediol and vitamin D3Be combined bring poor compliance the problem of, pass through by
It is 1 that the two, which leads to hypereutectic technological means to have synthesized molar ratio,:1 compound achievees the purpose that improve patient's compliance.This is common
Crystalline substance avoids the problem that bringing using physical mixed, and significantly improves vitamin D under illumination condition3Chemical stability.
