An Efficient Synthetic Approach Towards Benzo[b]pyrano[2,3-e][1,4]diazepines, and Their Cytotoxic Activity.

ABSTRACT: In search of unprecedented tri and/or tetrapod pharmacophoric conjugates, a series of 32 new 4-ethyl-1H-benzo[b][1,4]diazepin-2(3H)-ones were synthesized and properly elucidated using MS, IR, NMR, and elemental analysis. In vitro investigation of 11 compounds of this series, using a panel of two human tumor cell lines namely; human breast adenocarcinoma (MCF-7), and human colorectal carcinoma (HCT-116), revealed promising cytotoxic activities. Among all synthesized compounds, analogue 9 displayed maximum cytotoxicity with IC50 values of 16.19 ± 1.35 and 17.16 ± 1.54 ?M against HCT-116 and MCF-7, respectively, compared to standard drug doxorubicin.

1,4-Dihydro-benzo[g]quinoxaline-2,3-dione.

Project description:The title compound, C12H8N2O2, was prepared by the reaction of the diethyl ester of naphthalene-bis-(oxamate) with tert-BuNH2. The mol-ecule is nearly planar, with an r.m.s. deviation of 0.017?Å from the plane through all 16 non-H atoms. In the crystal, a three-dimensional network is formed, composed of layers of mol-ecules along the b- and c-axis directions, due to the formation of inter-molecular N-H?O hydrogen bonds, as well as of chains along the a-axis direction due to parallel displaced sandwich-type ?-? inter-actions with average distances between the inter-acting mol-ecules in the range 3.35-3.40?Å.

Project description:In the title compound, C(20)H(15)N(3)O, the diazepine ring adopts a boat conformation. The dihedral angle between pyridine and benzene rings is 55.2?(1)°. The benzoyl phenyl ring forms dihedral angles of 49.4?(1) and 75.9?(1)°, respectively, with the pyridine and benzene rings. In the crystal, mol-ecules are linked into centrosymmetric dimers by pairs of C-H?N hydrogen bonds.

An efficient synthesis of novel pyrano[2,3-d]- and furopyrano[2,3-d]pyrimidines via indium-catalyzed multi-component domino reaction.

Project description:Various novel pyrano [2,3-d]pyrimidines 5 and furopyrano [2,3-d]pyrimidines 7 were synthesized in 80-99% yields via a multicomponent domino Knoevenagel/hetero-Diels-Alder reaction of 1,3-dimethyl barbituric acid with an aromatic aldehyde and ethyl vinyl ether/2,3-dihydrofuran in presence of 1 mol% of indium(III) chloride. The reaction also proceeds in aqueous media without using any catalyst, but the yield is comparatively less (65-70%).

2,2-Dimethyl-2,3-dihydro-pyrano[2,3-a]carbazol-4(11H)-one.

Project description:The title compound, C(17)H(15)NO(2), was prepared from 1-hydroxy-carbazole and 3,3-dimethyl-acrylic acid with a mixture of AlCl(3) and POCl(3) as the cyclization catalyst. Owing to the presence of the -CMe(2)- group, the mol-ecule is not quite planar. In the crystal structre, strong N-H?O hydrogen bonds and weaker C-H?? inter-actions occur, and a slipped ?-? stacking inter-action [centroid-centroid separation = 3.8425?(8)?Å] is also observed.

2,2,10-Trimethyl-2,3-dihydro-pyrano[2,3-a]carbazol-4(11H)-one.

Project description:The title compound, C(18)H(17)NO(2), was prepared from 1-hydr-oxy-8-methyl-carbazole and 3,3-dimethyl-acrylic acid with trifluoro-acetic acid as the cyclization catalyst. Due to the -CMe(2)- group, the mol-ecule is not quite planar. The packing is dominated by the strong N-H?O hydrogen bonds and some weaker C-H?O and C-H?? inter-actions. ?-? Stacking inter-actions [centroid-centroid separation = 3.806?(2)?Å] join neighboring mol-ecules into loosely connected inversion dimers.

2,2,9-Trimethyl-2,3-dihydro-pyrano[2,3-a]carbazol-4-(11H)-one.

Project description:The title compound, C(18)H(17)NO(2), was prepared from 1-hydr-oxy-7-methyl-carbazole and 3,3-dimethyl-acrylic acid with trifluoro-acetic acid as the cyclization catalyst. The mol-ecules contain an essentially planar 6-methyl-indole unit. The second aromatic ring is significantly bent away from the plane of this unit, with maximum deviations of 0.171?(1) and 0.185?(1)?Å for two of the C atoms. In the crystal structure, there are neither N-H?O hydrogen bonds nor ?-? stacking between the aromatic sections of neighboring mol-ecules. There is only one weak C-H?O hydrogen bond and a number of weak C-H?? inter-actions.

Project description:Mol-ecules of the title compound, C16H16N2O2, occupy special positions on the twofold rotation axes. The heterocyclic ring adopts a slightly twisted envelope conformation with one of the two junction carbon atoms as the flap. The mean planes through the two halves of the mol-ecule form a dihedral angle of 72.01 (2)°. In the crystal, mol-ecules are linked by pairs of C-H⋯O and N-H⋯C contacts into layers parallel to (100). H⋯H contacts make the largest contribution to the Hirshfeld surface (58.9%).

6-Amino-1-benzyl-4-(4-chloro-phen-yl)-3-(4-pyrid-yl)-1,4-dihydro-pyrano[2,3-c]pyrazole-5-carbonitrile.

Project description:The crystal structure of the title compound, C(25)H(18)ClN(5)O, was determined in the course of our studies on the synthesis of 1,4-dihydro-pyrano[2,3-c]pyrazole as an inhibitor of the p38 mitogen-activated protein kinase (MAPK). The compound was prepared via a base-catalysed synthesis from 1-benzyl-3-(4-pyrid-yl)-1H-pyrazol-5(4H)-one with p-chloro-aldehyde and malononitrile. The crystal data obtained were used to generate a three-dimensional pharmacophore model for in silico database screening. The phenyl ring is disordered over two positions, with site occupancy factors of 0.55 and 0.45. The dihedral angles between the 1,4-dihydropyrano[2,3-c]pyrazole unit and the chloro-phenyl and pyridine rings are 83.7 (1) and 16.0 (1)°, respectively. The chloro-phenyl and pyridine rings make a dihedral angle of 86.8 (2)°.
