Definitions
- Crystalline forms of intermediates for carbapenem antibiotics are desirable from a stability and purity standpoint. These compounds facilitate the synthesis of carbapenem antibiotics on a commercial scale.
- crystalline forms of the compound 2S-cis-3-[[(4-mercapto-2-pyrrolidinyl)carbonyl]-amino] benzoic acid have been discovered and characterized.
- Crystalline 2S-cis-3-[[(4-mercapto-2-pyrrolidinyl)carbonyl]-amino]benzoic acid and pharmaceutically acceptable salts and solvates thereof are disclosed.
- the compounds can generally be synthesized taking into account the disclosure of U. S. Patent No. 5,478,820 granted on December 26, 1995. This patent does not disclose the side chain in crystalline form.
- Figure 1 is an X-Ray Powder Diffraction pattern of Compound I, in unsolvated form
- Figure 2 is an X-Ray Powder Diffraction pattern of Compound I as the 1-butanol solvate
- Figure 3 is an X-Ray Powder Diffraction pattern of Compound I, as the acetic acid solvate.
- the compound has the following structural formula:
- the salt form of the compound can be protonated as shown in the following:
- X represents a negatively charged counterion.
- the salt forms can also be present in the form of a solvate.
- the crystalline forms of the compound are characterized below by virtue of their X-Ray Powder Diffraction (XRPD) patterns.
- the XRPD patterns were collected on a Philips APD 3720 automated powder diffractometer.
- the x-ray generator employed a copper target, an accelerating potential of 45 kV and a filament emission of 40 mA. Diffraction patterns were collected from 2°C to 40°C.
- the hydrochloride salt of the compound (unsolvated material) was characterized as having an XRPD pattern at 5.5, 5.3, 4.9, 4.3, 4.1, 3.9, 3.8, 3.7, 3.6, 3.3, 3.2, 2.9, 2.6 and 2.3 angstroms. More complete XRPD data pertaining to the compound is shown below in Table 1.
- Step size sample time 0.015 deg, 0.20 s, 0.075 deg/s
- the hydrochloride salt 1-butanol solvate was shown to exhibit patterns such as the ERPD pattern shown as Figure 2. Characteristic D-spacings are 14.6, 7.3, 5.6, 4.9, 4.2, 4.0, 3.9, 3.8, 3.7, 3.6, 3.5, 3.3, 3.0 and 2.9 Ang. More complete XRPD data pertaining to the solvate is shown below in Table 2.
- Step size sample time 0.015 deg, 0.20 s, 0.075 deg/s
- Solid material which was exposed to acetic acid was characterized as having an XRPD pattern at 5.4, 5.3, 5.1, 4.2, 3.8, 3.6, 3.4, 3.1, 2.7 and 2.6 angstroms. More complete XRPD data pertaining to the solvate is shown below in Table 3.
- Peak position criterion Top of smoothed data Cryst peak width range 0.00-2.00 deg
- the crystalline compound of the present invention is useful in various pharmaceutically acceptable salt forms, for the synthesis of carbapenem compounds that are in turn useful for the treatment of bacterial infections in animal and human subjects.
- pharmaceutically acceptable salt refers to those salt forms which would be apparent to the pharmaceutical chemist, i.e., those which are substantially non-toxic and which provide the desired pharmacokinetic properties, palatability, absorption, distribution, metabolism or excretion.
- Other factors, more practical in nature, which are also important in the selection, are cost of the raw materials, ease of crystallization, yield, stability, hygroscopicity and flowability of the resulting bulk drug.
- the intermediate compound is protonated, and is found in association with a negatively charged counterion, represented by the generic X".
- a negatively charged counterion represented by the generic X.
- charge balancing counterion X Representative examples of such counterions are the following: acetate, adipate, aminosalicylate, anhydromethylenecitrate, ascorbate, aspartate, benzoate, benzenesulfonate, bicarbonate, bisulfate, bromide, citrate, camphorate, camphorsulfonate, carbonate, chloride, digluconate, edetate, edisylate, estolate, ethanesulfonate, fumarate, glucoheptanoate, gluconate, glutamate, glycerophosphate, glycolate, hydroxynaphthoate, 2-hydroxyethanesulfonate, iodide, lactate, lactobionate, malate, maleate, man
- the preferred form of the crystalline compound is the hydrochloride salt form.
- the compound can be produced in accordance with the following non-limiting examples.
- the BOC protected sidechain 1 (prepared according to the teachings of PCT WO97/06154 published on February 20, 1997) was dissolved in 1.5 L of a 1 N solution of dry hydrogen chloride in acetic acid (30 min). Gas evolution was observed and the reaction product slowly crystallized. After filtering, washing (with acetic acid and hexane) and drying 137 g of product was obtained. The crystals contain acetic acid but are not a solvate.
