ABSTRACT: In the title compound, C(21)H(20)O(4), the central hepta-trienone unit is approximately planar, with a maximum atomic deviation of 0.1121?(11)?Å; the two benzene rings are twisted with respect to the hepta-trienone mean plane by 2.73?(5) and 29.31?(4)°. The mol-ecule exists in the enol form and the hy-droxy group forms an intra-molecular hydrogen bond with the neighboring carbonyl group. Weak inter-molecular C-H?O hydrogen bonding is present in the crystal structure.

Project description:The title compound, C(23)H(18)N(2)O(2)·0.5H(2)O, a derivative of the biologically active compound curcumin, crystallizes with two organic mol-ecules and a solvent water mol-ecule in the asymmetric unit. Each of the two independent mol-ecules is close to being planar (the dihedral angles between the indole ring systems are approximately 9 and 12°) and each exists in the keto-enol form. There is an intra-molecular O-H?O hydrogen bond between the keto and enol groups. In the crystal, the components interact by way of N-H?N, N-H?O and O-H?O hydrogen bonds.

2-Hy-droxy-7-nitro-cyclo-hepta-2,4,6-trien-1-one.

Project description:The title compound, also known as 7-nitro-tropolone, C7H5NO4, exists in the crystalline state as the 2-hy-droxy-7-nitro-cyclo-hepta-2,4,6-trien-1-one tautomer and not as 2-hy-droxy-3-nitro-cyclo-hepta-2,4,6-trien-1-one.

Project description:In the title compound, [Pb(C(10)H(11)O(2))(2)](n) or [Pb(hino)(2)](n), the lead(II) ion is chelated by two hinokitiolate ligands in a distorted square-pyramidal configuration, with Pb-O bond lengths in the range 2.327 (6)-2.479 (9) Å. The 6s(2) lone electron pair of the lead(II) ion becomes stereochemically active and is directed towards the apex of this pyramid. The crystal structure of the title compound consists of chains formed by the bis-(hinokitiolato)lead(II) mol-ecules situated along the twofold screw axis. The coordination sphere around the lead(II) ion is completed by three additional O atoms, at 2.625 (7), 3.016 (8) and 3.064 (8) Å, from the two neighbouring Pb(hino)(2) units. Both isopropyl groups are rotationally disordered.

Synthesis and evaluation of 1,7-diheteroarylhepta-1,4,6-trien-3-ones as curcumin-based anticancer agents.

Project description:Thirty (1E,4E,6E)-1,7-diaryl-1,4,6-heptatrien-3-ones, featuring a central linear trienone linker and two identical nitrogen-containing heteroaromatic rings, were designed and synthesized as curcumin-based anticancer agents on the basis of their structural similarity to the enol-tautomer of curcumin, in addition to taking advantage of the possibly enhanced pharmacokinetic profiles contributed by the basic nitrogen-containing heteroaromatic rings. Their cytotoxicity and antiproliferative activity were evaluated towards both androgen-dependent and androgen-independent prostate cancer cell lines, as well as HeLa human cervical cancer cells. Among them, the ten most potent analogues are 5- to 36-fold more potent than curcumin in inhibiting cancer cell proliferation. The acquired structure-activity relationship data indicate (i) that (1E,4E,6E)-1,7-diaryl-1,4,6-heptatrien-3-ones represent a potential scaffold for development of curcumin-based agents with substantially improved cytotoxicity and anti-proliferative effect; and (ii) 1-alkyl-1H-imidazol-2-yl and 1-alkyl-1H-benzo[d]imidazole-2-yl serve as optimal heteroaromatic rings for increased in vitro potency of this scaffold. Two of most potent compounds displayed no apparent cytotoxicity toward MCF-10A normal mammary epithelial cells at 1 ?M concentration. Treatment of PC-3 prostate cancer cells with the most potent compound led to appreciable cell cycle arrest at a G1/G0 phase and cell apoptosis induction.

3-{[(4Z)-1,2-Dimethyl-5-oxoimidazol-4-yl-idene]meth-yl}-4-hy-droxy-benzonitrile.

Project description:In the title compound, C(13)H(11)N(3)O(2), an intra-molecular O-H⋯N hydrogen bond generates an S(7) ring. The dihedral angle between the mean plane of the benzene ring and the imidazolidinone ring is 3.05 (2)°. In the crystal, inversion-related mol-ecules are linked by dual C-H⋯O(carbon-yl) hydrogen bonds to form a dimer with an R(2) (2)(14) graph-set motif. A C-H⋯O(hy-droxy) inter-action links pairs of mol-ecules into another type of cyclic dimer with an R(2) (2)(18) motif. The mol-ecules are further linked by C-H⋯N inter-actions to form layers parallel to (001). Offset π-π stacking [3.3877 (8) Å] is observed in the crystal structure, with an inter-planar spacing between the planes of neighboring benzene rings of 3.444 (1) Å.

N'-[(1E)-(2-Hy-droxy-naphthalen-1-yl)methyl-idene]-2-meth-oxy-benzohydrazide.

Project description:There are three independent mol-ecules in the asymmetric unit of the title compound, C(19)H(16)N(2)O(3), in which the dihedral angles between the naphthalene ring system and the benzene ring are 7.52?(16), 18.15?(18), and 13.9?(2)°. All the mol-ecules exist in the trans configuration with respect to the methyl-idene units. In each mol-ecule there is one O-H?N and one N-H?O intra-molecular hydrogen bond. In the crystal, two of the mol-ecules are linked via a bifurcated N-H?(O,O) hydrogen bond. All three mol-ecules are further linked via C-H?O inter-actions.

Project description:The title compound, C(17)H(16)Cl(2)N(2)O(3)·H(2)O, displays a trans conformation with respect to the C=N double bond. The dihedral angle between the two benzene rings is 30.77 (5)° and there is one intra-molecular N-H⋯O hydrogen bond. In the crystal, mol-ecules are linked by hydrogen bonding to the water molecules of crystallization, which acts as both an acceptor and a donor, into a three-dimensional network.

Structure-activity relationship studies of 1,7-diheteroarylhepta-1,4,6-trien-3-ones with two different terminal rings in prostate epithelial cell models.

Project description:To systematically investigate the structure-activity relationships of 1,7-diheteroarylhepta-1,4,6-trien-3-ones in three human prostate cancer cell models and one human prostate non-neoplastic epithelial cell model, thirty five 1,7-diarylhepta-1,4,6-trien-3-ones with different terminal heteroaromatic rings have been designed for evaluation of their anti-proliferative potency in vitro. These target compounds have been successfully synthesized through two sequential Horner-Wadsworth-Emmons reactions starting from the appropriate aldehydes and tetraethyl (2-oxopropane-1,3-diyl)bis(phosphonate). Their anti-proliferative potency against PC-3, DU-145 and LNCaP human prostate cancer cell lines can be significantly enhanced by the manipulation of the terminal heteroaromatic rings, further demonstrating the utility of 1,7-diarylhepta-1,4,6-trien-3-one as a potential scaffold for the development of anti-prostate cancer agents. The optimal analog 40 is 82-, 67-, and 39-fold more potent than curcumin toward the three prostate cancer cell lines, respectively. The experimental data also reveal that the trienones with two different terminal aromatic rings possess greater potency toward three prostate cancer cell lines, but also have greater capability of suppressing the proliferation of PWR-1E benign human prostate epithelial cells, as compared to the corresponding counterparts with two identical terminal rings and curcumin. The terminal aromatic rings also affect the cell apoptosis perturbation.

8-Hy-droxy-5-(hy-droxy-meth-yl)quinolin-1-ium chloride.

Project description:The title compound, C(10)H(10)NO(2) (+)·Cl(-), contains a quinoline ring system which is essentially planar, with the largest deviation from the mean plane being 0.017 (1) Å. In the crystal, the ion pairs and their inversion-symmetry-related partners are linked by N-H⋯Cl and O-H⋯Cl hydrogen bonds to form tetramers which are further connected through O-H⋯O hydrogen bonds, building infinite one-dimensional chains parallel to the [010] direction.

Benzyl N-(2-hy-droxy-1-{N'-[(1E)-2-hy-droxy-benzyl-idene]hydrazinecarbon-yl}eth-yl)carbamate.

Project description:The mol-ecule of the title compound, C(18)H(19)N(3)O(5), adopts a curved arrangement with the terminal benzene rings lying to the same side. The hydroxyl-benzene ring is close to coplanar with the adjacent hydrazine residue [dihedral angle = 11.14?(12)°], an observation which correlates with the presence of an intra-molecular O-H?N hydrogen bond. The benzyl ring forms a dihedral angle of 50.84?(13)° with the adjacent carbamate group. A twist in the mol-ecule, at the chiral C atom, is reflected in the dihedral angle of 80.21?(12)° formed between the amide residues. In the crystal, two-dimensional arrays in the ac plane are mediated by O-H?O and N-H?O hydrogen bonds.
