• the cyclic nucleotides cAMP and cGMP are synthesized by adenylyl and guanylyl cyclases, respectively, and serve as secondary messengers in several cellular pathways.

• succinic acid or "succinate salt” is meant to encompass all solid state forms containing succinic acid and the quinoline compound (formula 1 ) associated in the solid state including by ionic bonds and/or hydrogen bonds.
• crystalline means a material that has an ordered, long range molecular structure.
• the degree of crystallinity of a crystal form can be determined by many techniques including, for example, powder X-ray diffraction, moisture sorption, differential scanning calorimetry, solution calorimetry, polarized light microscopy and dissolution properties.
• Crystalline organic compounds consist of a large number of atoms that are arranged in a periodic array in three-dimensional space.
• the structural periodicity normally manifests distinct physical properties, such as sharp, explicit spectral features by most spectroscopic probes (e.g., X-ray diffraction, infrared and solid state NMR).
• X-ray diffraction X-ray diffraction
• Crystals yield explicit diffraction maxima that arise at specific angles consistent with the lattice interplanar spacings, as predicted by Bragg's law.
• amorphous materials do not possess long-range order. They often retain additional volume between molecules, as in the liquid state.
• Amorphous solids normally unveil a featureless XRD pattern with broad, diffuse halos because of the absence of the long range order of repeating crystal lattice.
• Powder X-ray diffraction, (PXRD) has reportedly been used to characterize different crystal forms of organic compounds (e.g., compounds useful in pharmaceutical compositions). See, for example, U.S. Pat. Nos. 5,504,216 (Holohan et al), 5,721 ,359 (Dunn et al.), 5,910,588 (Wangnick et al.), 6,066,647 (Douglas et al.), 6,225,474 (Matsumoto et al.), 6,239,141 (Allen et al.), 6,251 ,355 (Murata et al.), 6,288,057 (Harkness), 6,316,672 (Stowell et al.), and 6,329,364 (Groleau).
• PXRD Powder X-ray diffraction
• Crystalline materials are preferred in many pharmaceutical applications. Crystalline forms are generally thermodynamically more stable than amorphous forms of the same substance. This thermodynamic stability is preferably reflected in the lower solubility and improved physical stability of the crystalline form.
• the regular packing of the molecules in the crystalline solid preferably denies the incorporation of chemical impurities. Hence crystalline materials generally possess higher chemical purity than their amorphous counterparts.
• the packing in the crystalline solid generally constrains the molecules to well defined lattice positions and reduces the molecular mobility that is the prerequisite for chemical reactions. Hence, crystalline solids, with very few notable exceptions, are chemically more stable than amorphous solids of the same molecular composition.
• the crystalline form of the crystalline polymorph of the succinate salt of the present invention has the powder X-ray diffraction profile provided in FIG 1.
• Characteristic diffraction peaks as used herein are unique peaks to identify the form.
• the characteristic peaks are selected from about 20 of the most intense peaks, more preferably from about 10 of the most intense peaks, and most preferably from about 3 to 5 of the most intense peaks in the diffraction pattern.
• the drug form For a drug form to be practically useful for human or animal therapy, it is also desirable that the drug form to be non-deliquescent, and more particularly, exhibit minimal hygroscopicity. Dosage forms containing highly hygroscopic drugs require protective packaging, and may exhibit altered dissolution if stored in a humid environment. Thus it is desirable to identify non-hygroscopic crystalline salts of a drug.
• a drug, crystalline or non-crystalline may exist in an anhydrous form, or as a hydrate or solvate or hydrate/solvate.
• the hydration state and solvation state of a drug affects its solubility and dissolution behavior.
