Abstract top

The asymmetric unit of the title compound, C27H32O, contains two and a half molecules. In the crystal structure, one of the molecules lies on a crystallographic twofold rotation axis. The dihedral angles between the benzene rings are 12.17 (6), 16.29 (11) and 51.24 (8)° for the three molecules. The dihedral angles between the benzene rings of each molecule in the asymmetric unit are 12.17 (6) and 16.29 (11)°

Comment top

The title compound, (2E,5E)-2,5-bis(4-tert-butylbenzylidene)cyclopentanone (I), is one of the monocarbonyl analogues of curcumin designed and synthesized by our group. Curcumin has been found to possess a variety of pharmaceutical applications, for example, inhibiting the mutations and the formation of tumors, antioxidation, anti-inflammation, anti-virus, and decreasing total cholesterol and LDL cholesterol level (Began et al., 1999; Kawamori et al., 1999; Poorichaya et al., 2007). In previous studies, curcumin was found to be able to effect the activity of enzyme 11-beta-hydroxysteroid dehydrogenase type-1 (11-beta-HSD1), which catalyzes glucocorticoid conversion between active form (corticosterone in rodents) and inactive form (dehydrocortisone in rodents) and then regulates downstream target genes leading to increased hepatic glucose production and lipolysis in adipose tissue (Livingstone & Walker, 2003; Saiah, 2008). According to the structural disadvantages of curcumin responsible for its weak pharmacokinetic profiles, a series of mono-carbonyl analogues were designed and synthesized (Liang et al., 2008), and their 11-beta-HSD1-regulating activities in vitro were evaluated using intact Leydig cells. The title compound (I) showed an 11-beta-HSD1-regulating bioactivity with ED50 = 3029 nM on 11-beta-HSD1 oxidase and IC50 = 12278 nM against reductase of this enzyme, comparable to curcumin performs on 11-beta-HSD1 regulation (data not shown). Among these derivatives, some crystal structures are reported (Liang, Tian et al., 2007; Liang, Yang et al., 2007). In the present paper, we describe the crystal structure of compound (I). The geometrical parameters of title compound (I) are normal and there are three independent molecules. The dihedral angles between two benzene rings in each are 12.17 (6)°, 16.29 (11)°, 51.24 (8)°, respectively.

Experimental top

To a solution of 15 mmol 4-tert-butybenzaldehyde in MeOH (10 ml) was added 7.5 mmol cyclopentanone. The solution was stirred at room temperature for 20 min, followed by added dropwise 2.0 mol/L NaOCH3 (3.75 ml, 7.5 mmol) in methanol. The mixture was stirred at room temperature for 1.5 h and monitored with TLC. When the reaction was complete, the residue was poured into saturated NH4Cl solution and filtered. The precipitate was washed and purified by chromatography over silica gel using CH2Cl2 / CH3OH as the eluent to afford the pure product (yield: 66.9%). Single crystals of (I) were grown in a CH2Cl2—CH3CH2OH mixture (5:1 v/v) by slow evaporation (mp 452–454 K). 1H-NMR (CDCl3): 1.35 (18H, s, CH3), 3.11 (4H, S, CH2—CH2), 7.47 (4H, d, J=8.4 Hz, Ar—H(2,6)), 7.56 (4H, d, J=8.4 Hz, Ar—H(3,5)), 7.59 (2H, s, CH). ESI-MS m/z: 373.69 (M+1), calcd for C27H32O: 372.53.

Refinement top

The H atoms were positioned geometrically (C—H = 0.93–0.97 Å) and refined as riding with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C).

Special details top

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.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
