The compound, the crystalline forms, the single crystal and the amorphous form can stably exist and exhibit good solid forms, suitable for medicine-making. Furthermore, these products possess high purity and less single impurity. Moreover, the preparation methods of the present disclosure are easy to implement due to the simple processes with mild reaction conditions, and could produce products of high yield and high purity without complex purification steps. Furthermore, the preparation methods may facilitate safety, environmental protection, and industrial production.
摘要:
The present disclosure provides a triazole antibacterial derivative and a pharmaceutical composition thereof and a use thereof and in particular relates to a compound represented by the following formula (I), and a racemate, a stereoisomer, a tautomer, an oxynitride or a pharmaceutically acceptable salt thereof: The compound of the present disclosure has a desirable water solubility and can be formulated into an injection for use without adding a cosolvent having a potential safety risk (such as hydroxypropyl-β-cyclodextrin, sulfobutylether-β-cyclodextrin, and the like), facilitating drug administration for patients, and greatly improving clinical safety. The drug can be used even by patients with moderate or severe renal impairment, thereby expanding the application scope of the drug.
摘要:
The invention discloses an oral solid preparation containing any one, or a mixture of two or more of crystalline form I, II, III, and IV of the compound represented by formula (A). The oral solid preparation of the present invention disintegrates rapidly, increasing dissolution rate thereof, thereby improving bioavailability. In particular, it is possible to solve the problem that an active material (active ingredient), which is high hygroscopic and becomes sticky after moisture absorption, can not be effectively disintegrated by conventional disintegrants. The present invention further relates to a use of the oral solid preparation in preparing an angiotensin II receptor antagonist or a use thereof in preparing medicine for preventing and/or treating hypertension, chronic heart failure and diabetic nephropathy.
摘要:
The present disclosure provides a posaconazole derivative, a pharmaceutical composition and use thereof, which specifically include a compound represented by the following formula (I), a racemate, stereoisomer, tautomer, oxynitride, or a pharmaceutically acceptable salt thereof: The compounds of the present disclosure have strong antifungal activity, high safety, and good water solubility, without the need for the addition of a cosolvent (such as hydroxypropyl-β-cyclodextrin, sulfobutyl ether-β-cyclodextrin, and the like) with potential safety risks. Furthermore, the formulation process of the compound could have less difficulty and less cost, and therefore can be used to prepare improved antifungal drugs.
摘要:
The invention belongs to the technical field of pharmaceutical chemistry, and particularly pertains to benzimidazole derivatives, and preparation process and pharmaceutical uses thereof. Benzimidazole derivatives include Ligustrazine and NO donor derivatives. The kind of the compounds can rapidly release Ligustrazine or No in vivo, so that they can produce effective synergetic effects with Azilsartan, to enhance the anti-hypertension effect, and reduce adverse effects, and the released Ligustrazine can produce ideal protection to patients' livers and kidneys, thereby filling blanks in the prior art.
