Crystal structures of 2-meth-oxy-isoindoline-1,3-dione, 1,3-dioxoisoindolin-2-yl methyl carbonate and 1,3-dioxo-2,3-di-hydro-1H-benzo[de]isoquinolin-2-yl methyl carbonate: three anti-convulsant compounds.

The title compounds, C9H7NO3, (1), C10H7NO5, (2), and C14H9NO5, (3), are three potentially anti-convulsant compounds. Compounds (1) and (2) are isoindoline derivatives and (3) is an iso-quinoline derivative. Compounds (2) and (3) crystallize with two independent mol-ecules (A and B) in their asymmetric units. In all three cases, the isoindoline and benzoiso-quinoline moieties are planar [r.m.s. deviations are 0.021 Å for (1), 0.04 and 0.018 Å for (2), and 0.033 and 0.041 Å for (3)]. The substituents attached to the N atom are almost perpendicular to the mean planes of the heterocycles, with dihedral angles of 89.7 (3)° for the N-O-Cmeth-yl group in (1), 71.01 (4) and 80.00 (4)° for the N-O-C(=O)O-Cmeth-yl groups in (2), and 75.62 (14) and 74.13 (4)° for the same groups in (3). In the crystal of (1), there are unusual inter-molecular C=O⋯C contacts of 2.794 (1) and 2.873 (1) Å present in mol-ecules A and B, respectively. There are also C-H⋯O hydrogen bonds and π-π inter-actions [inter-centroid distance = 3.407 (3) Å] present, forming slabs lying parallel to (001). In the crystal of (2), the A and B mol-ecules are linked by C-H⋯O hydrogen bonds, forming slabs parallel to (10-1), which are in turn linked via a number of π-π inter-actions [the most significant centroid-centroid distances are 3.4202 (7) and 3.5445 (7) Å], forming a three-dimensional structure. In the crystal of (3), the A and B mol-ecules are linked via C-H⋯O hydrogen bonds, forming a three-dimensional structure, which is consolidated by π-π inter-actions [the most significant inter-centroid distances are 3.575 (3) and 3.578 (3) Å].

Chemical context

Traumatic brain injury (TBI) is a neurological disorder that is defined as damage to the brain resulting from external mechanical force, including accelerating, decelerating and rotating forces (Langlois et al., 2003 ▶, 2005 ▶; Ashman et al., 2006 ▶; Coronado et al., 2011 ▶). TBI also exacerbates seizure severity in individuals with pre-existing epilepsy (Ferraro et al., 1999 ▶), being one example of the process of epileptogenesis (Christensen et al., 2009 ▶). In this context, it has been demonstrated that early lesions in the central nervous system (CNS) alter the transport dynamic of the blood–brain barrier (BBB) and deteriorate the balance of the inhibitory and excitatory neurotransmitter system (Scantlebury et al., 2005 ▶]. This neuronal dysfunction predisposes to subsequent development of spontaneous recurrent seizures in the presence of prior subtle brain malformation (Love, 2005 ▶].

TBI is the major cause of death in young individuals (14–24 years) from industrialized countries, with head injuries accounting for 25–33% of all trauma-related deaths (Abdul-Muneer et al., 2014 ▶). Disorders like memory loss, depression and seizures are some of the side effects to TBI. TBI affects people over 75 years of age because of falls and of 17–25 years of age because of accidents (Langlois et al., 2003 ▶, 2005 ▶; Ashman et al., 2006 ▶; Coronado et al., 2011 ▶). At present, there are no effective treatments available for TBI and there is thus a critical need to develop novel and effective strategies to alter the disease course. As indicated above, this health condition is quite similar to epilepsy in some instances and thus our earlier work (Alexander et al., 2013 ▶; Jackson et al., 2012 ▶; Edafiogho et al., 2007 ▶) on developing anti­convulsant compounds for the treatment of epilepsy is relevant.

Our research on pharmacologically active compounds is a multi-pronged approach, which involves synthesis, chemical characterization, computer modeling, pharmacological evaluation, and structure determination (North et al., 2012 ▶; Gibson et al., 2009 ▶). From this comprehensive approach, structure–activity correlations can be made to improve the existing pharmacologically active compounds. From our studies, we identified three imido­oxy derivatives as potential drug candidates for TBI that underwent anti­convulsant evaluation to test their ability to inhibit the onset of seizures in the in vivo MES, scPTZ test models. The MES (maximal electroshock seizure evaluation) test presented activity in animals in phase 1 testing.

2-Meth­oxy­isoindoline-1,3-dione, (1), studied by X-ray techniques, was inactive in MES and scPTZ in mice, but showed MES protection in rat studies at 50 mg kg−1 at 4 h and also protected 1/4 mice at three different time inter­vals (0.50, 1 and 2 h) in the 6 Hz test (Jackson, 2009 ▶). For scPTZ studies, the compound was Class III (no activity at 300 mg kg−1). The compound is a dual MES/6Hz active compound. Compounds (2) and (3) showed similar activity.

The title compounds, containing either an isoindoline-1,3-dione moiety, (1) (Fig. 1 ▶) and (2) (Fig. 2 ▶), or an iso­quinoline-1,3-dione moiety, (3) (Fig. 3 ▶), have been studied extensively for their anti­convulsant effects with promising results. Herein, we report on the crystal structures of these new structurally related compounds.

Structural commentary

In compound (1), the isoindoline ring is planar [r.m.s. deviation = 0.017 (4) Å]. The meth­oxy O atom, O3, deviates from this plane by 0.176 (6) Å while the methyl C atom, C9, is out of the plane by 1.105 (9) Å. The meth­oxy substituent is oriented almost perpendicular to the indoline ring with the dihedral angle between the mean planes of the indoline ring and the meth­oxy substituent being 89.7 (3)°.

In compound (2), there are two mol­ecules (A and B) in the asymmetric unit. The isoindoline ring is planar [r.m.s. deviation = 0.0327 (9) for A and 0.0147 (9) Å for B] with the dione O atoms significantly out of the plane for mol­ecule A but not for mol­ecule B [0.172 (1) and 0.123 (1) Å for atoms O1 and O2, respectively, in A but by only 0.013 (1) and 0.002 (1) Å, respectively, in B]. The carbonato moiety is planar in both mol­ecules [r.m.s. deviations of 0.0066 (2) and 0.0027 (5) Å for A and B, respectively] and makes dihedral angles of 71.50 (3) and 80.03 (4)° with the benzoiso­quinoline ring in A and B, respectively, indicating that these substituents are oriented almost perpendicular to the benzoiso­quinoline ring system.

In compound (3), there are also two mol­ecules (A and B) in the asymmetric unit. In both mol­ecules, the benzoiso­quinoline ring systems are planar (r.m.s. deviations for A and B = 0.033 and 0.015 Å, respectively). The meth­oxy O atom deviates from this plane by 0.126 (1) for atom O5A in A and 0.156 (1) Å for atom O5B in B. The methyl carbonate moieties are planar [r.m.s. deviations of 0.007 (1) and 0.003 (1) Å for A and B, respectively] and these substituents are oriented almost perpendicular to the iso­quinoline rings, making dihedral angles of 71.50 (3) and 80.04 (4)° for A and B, respectively. As in (2), these dihedral angles are significantly smaller than that found for (1).

Supra­molecular features

In the crystal of (1), there are C—H⋯O hydrogen bonds (Fig. 4 ▶ and Table 1 ▶) and π–π inter­actions present, forming slabs lying parallel to (001) [Cg1⋯Cg2i,ii = 3.407 (3) Å; Cg1 and Cg2 are the centroids of rings N1/C1/C2/C7/C8 and C2–C7, respectively; symmetry codes: (i) x − 1, y, z; (ii) x + 1, y, z].

In the crystal of (2), the A and B mol­ecules are linked by C—H⋯O hydrogen bonds (Fig. 5 ▶ and Table 2 ▶), forming slabs parallel to (10). The slabs are in turn linked via π–π inter­actions, forming a three-dimensional structure with centroid–centroid distances of 3.4202 (7) for Cg1⋯Cg5ii and 3.5445 (7) Å for Cg2⋯Cg4ii [Cg1, Cg2, Cg4 and Cg5 are the centroids of rings N1A/C1A/C2A/C7A/C8A, C2A–C7A, N1B/C1B/C2B/C7B/C8B and C2B–C7B, respectively; symmetry code: (ii) x + 1, y, z − 1].

In the crystal of (3), the A and B mol­ecules are linked by C—H⋯O hydrogen bonds (Fig. 6 ▶ and Table 3 ▶), forming a three-dimensional structure, which is consolidated by π–π inter­actions [Cg1⋯Cg3iii = 3.578 (3), Cg2⋯Cg3iii = 3.575 (3) Å and Cg9⋯Cg10iv; Cg1, Cg2, Cg3, Cg9 and Cg10 are the centroids of rings N1A/C1A–C5A, C2A/C3A/C6A–C9A, C3A/C4A/C9A–C12A, C2B/C3B/C6B–C9B and C3B/C4B/C9B–C12B, respectively; symmetry codes: (iii) x, −y + , z − ; (iv) x, −y + , z + ].

Symmetry codes: (i) ; (ii) ; (iii) ; (iv) .

Inter­estingly, in the crystal of (2) one of the two dione moieties for each mol­ecule (O1A and O1B) has a short inter­molecular inter­actions with the central C atom of the carbonato group [O1A⋯C9A = 2.794 (1), O1B⋯C9B = 2.873 (1) Å], which is perpendicular to the carbonato plane indicating that both atoms, C9A and C9B, must have significant positive character. These inter­actions link the mol­ecules into dimers as shown in Figs. 6 ▶ and 7 ▶, respectively. This is also noticed to a lesser extent in (3) (Fig. 8 ▶) for mol­ecule A (but not for mol­ecule B), where a longer inter­molecular inter­action of 3.060 (3) Å is observed between atoms O2A and C13A, resulting in weakly associated dimers similar to that seen in the case of (2).

For mol­ecule B in compound (2), perpendicular inter­actions between atoms O1B and C9B (shown as dashed lines) link the mol­ecules into inversion dimers [symmetry code: (A) −x, −y + 1, −z − 1].

Database survey

A search of the Cambridge Structural Database (Version 5.35; Groom & Allen, 2014 ▶) for the indoline skeleton gave 26 hits. In all cases, the geometrical parameters of the indoline skeleton are similar to those observed in compounds (1) and (2). In the case of the iso­quinoline structure, there are only two structures containing the planar iso­quinoline moiety with similar geometrical parameters to the present structure, (3).

Synthesis and crystallization

Compound (1):

To a freshly prepared solution of sodium (2.3 g, 0.10 mol) in absolute ethanol (60 ml) was added a solution of N-hy­droxy­phthalimide (16.3 g, 0.10 mol) in absolute ethanol (350 ml), and the red reaction mixture was stirred at room temperature for 30 min. The brick-red precipitate was collected, washed with water, and dried in the oven at 373 K for 30 min to give 17.45 g (95%) of sodium phthalimide oxide as brick-red crystals; m.p. > 573 K. To the solution of sodium phthalimide oxide (0.92 g, 5 mmol) in water (15 ml) was added acetone (10 ml), followed by a solution of bromo­methane (0.66 g, 7 mmol). The reaction mixture was stirred at room temperature for 16 h, during which the red color disappeared. On standing at room temperature for 48 h, the product solidified in the aqueous mixture and was collected. Recrystallization from 2-propanol gave 0.72 g (78%) of compound (1) as plate-like colorless crystals: m.p. 395–397 K; 1H NMR (CDC13) δ 3.36 (s, 3H, J = 6 Hz, OCH3), 5.52, s, 1 H,CH, 7.87 (m, 4 H, phthalimido ring).

Compound (2):

To a solution of sodium phthalimide oxide (0.92 g, 5 mmol) in water (15 ml) was added acetone (10 ml), followed by a solution of bromo­(meth­oxy)methanone (0.97 g, 7 mmol). The reaction mixture was stirred at room temperature for 16 h, during which the red color disappeared. On standing at room temperature for 48 h, the product solidified in the aqueous mixture and was collected. Recrystallization from ethanol gave 0.82 g (74%) of compound (2) as colorless crystals: m.p. 410–411 K; 1H NMR (CDC13) δ 3.8 (s, 3H,OCH3), 7.86 (m, 4H, phthalimido ring).

Compound (3):

To a solution of sodium naphthalimide oxide, (1.18 g, 5 mmol), in water (50 ml), was added bromo­(meth­oxy)methanone (1.25g, 7 mmol) in acetone (10 ml). The red reaction mixture was stirred at room temperature. The red color disappeared within 5 min and the reaction mixture was filled with a white precipitate. After standing for 4 h, the white precipitate was collected, washed with water, and recrystallized from ethanol to give 1.46 g (89%) of compound (3) as colorless crystals: m.p. 483–485 K; 1H NMR (CDCl3) δ 3.79 (s, 3H, OCH3), 5.66 (s, 1H, CH), 7.65–8.50 (m, 6 H, naphthal­imido ring).

Refinement

Crystal data, data collection and structure refinement details for (1), (2) and (3) are summarized in Table 4 ▶. For all three compounds, the H atoms were positioned geometrically and refined as riding: C—H = 0.93–0.99 Å with U(H) = 1.5U eq(C) for methyl H atoms and = 1.2U(C) for other H atoms.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
