Definitions
- the invention relates to a novel solid form of (li?,2S)-l-(6-bromo-2-methoxy-3-quinolyl)-4- dimethylamino-2-(l-naphthyl)-l- henyl-butan-2-ol of formula (I),
- bedaquiline ( 1 R,2S)- 1 -(6-Bromo-2-methoxy-3 -quinolyl)-4-dimethylamino-2-( 1 -naphthyl)- 1 -phenyl- butan-2-ol
- bedaquiline (CAS no. 843663-66-1) and belongs to the group of quinoline derivatives that can be used as microbial inhibitors.
- the salt bedaquiline fumarate (1:1) is suitable for treatment or prevention of resistant microbial infections, especially microbial tuberculosis infections.
- Bedaquiline fumarate exists in one non-solvated crystalline form (Form A) and two pseudo- polymorphic forms B and C.
- the invention provides a solid form of bedaquiline with citric acid and methods of its preparation.
- the crystalline salt is prepared by a reaction of bedaquiline in the free base form with citric acid in a suitable solvent or mixtures of solvents.
- the prepared salt has advantageous physical-chemical characteristics for use in the pharmaceutical industry and in formulation of new dosage forms.
- FIG. 1 X-ray powder pattern of bedaquiline citrate (prepared in accordance with Process 2).
- Figure 2. IR spectrum of bedaquiline citrate (prepared in accordance with Process 2).
- a crystalline product is often stable, its required purity is easier to achieve and it dissolves more slowly.
- This invention provides a crystalline salt of bedaquiline in the solid phase.
- the invention provides a novel solid form of bedaquiline with citric acid that can be prepared and isolated in a crystalline form in adequate yields with high chemical purity.
- This solid form can be both anhydrous or non-solvated and in the form of hydrates/solvates of the respective solvents.
- the prepared novel solid form of bedaquiline may have various internal arrangements (polymorphism) with different physical-chemical properties depending on the conditions of its preparation. For this reason, the invention relates to the crystalline form of bedaquiline with citric acid or its mixtures in any ratio.
- This solid form is suitable for preparation and isolation of bedaquiline with high chemical and optical purity.
- the preparation of the solid form of bedaquiline of formula I is carried out by reaction of the free base of bedaquiline with citric acid.
- the reaction is conducted in a suitable solvent, which can be ketones, esters, ethers, amides, nitriles or organic acids, alcohols, aliphatic and aromatic hydrocarbons, chlorinated hydrocarbons, water or their mixtures.
- Aliphatic Q-C4 alcohols, esters or their mixtures are preferred.
- the most commonly used solvents are isopropanol, acetonitrile, tetrahydrofuran or their mixtures.
- the final product is typically precipitated or crystallized at temperatures in the range of -30°C to the boiling point of the solvent.
- the crystalline form of bedaquiline citrate (according to Example 2) is characterized by the reflections presented in Table 1.
- Table 1 includes reflections whose relative intensity value is higher than 1 percent.
- the characteristic diffraction peaks of bedaquiline citrate in accordance with this invention are as follows: 10.3; 12.0; 13.1; 18.3; 19.7 and 22,0 ⁇ 0.2° 2-theta.
- An example of the X-ray powder pattern is shown in Figure 1.
- the melting point of bedaquiline citrate is 174°C (DSC).
- a 10mm mask and a 1/4° fixed anti-dispersion slit were used.
- the irradiated area of the sample is 10 mm, programmable divergence slits were used.
- For the correction of the secondary array 0.02 rad Soller slits and a 5.0 anti-dispersion slit were used.
- ATR (ZnSe - single reflection) infrared spectra of the powder samples were measured with an infrared spectrometer (Nicolet Nexus, Thermo, USA) equipped with a DTGS KBr detector, in the measurement range of 600-4000 cm '1 and the spectral resolution of 4.0 cm "1 .
- the data were obtained at 64 spectrum accumulations.
- the OMNIC 6.2 software was used to process the spectra.
- the record of bedaquiline citrate was measured using a Discovery DSC device made by TA Instruments.
- the sample charge in a standard Al pot (40 yiL) was 4-5 mg and the heating rate was 5°C/min.
- As the carrier gas 5.0 N 2 was used at the flow rate of 50 ml/min.
