ABSTRACT: In the title compound, C20H18ClN3O3, the five- and six-membered heterocycles fused through a spiro C atom are inclined to each other at an angle of 87.4?(1)°. In the tricyclic ring system, the cyclo-hexene ring adopts an envelope conformation with the spiro atom as the flap. In the crystal, two sets of N-H?O hydrogen bonds link the mol-ecules into columns containing centrosymmetric R 2 (2)(7) ring motifs and propagating along the b-axis direction.

Project description:In the title compound, C18H15N3O3, the dihedral angle between the mean planes of the quinoline and indole ring systems [r.m.s. deviations = 0.189 (2) and 0.027 (2) Å, respectively] is 88.65 (5)°. The cyclo-hexene ring of the quinoline ring system adopts an envelope conformation with the central -CH2- C atom as the flap. In the crystal, mol-ecules are linked by two pairs of N-H⋯O hydrogen bonds, forming inversion dimers, and enclosing R 2 (2)(14) ring motifs. This arrangement results in the formation of chains propagating along [100].

(4S*)-2-Methyl-amino-3-nitro-4-(4-nitro-phen-yl)-5,6,7,8-tetra-hydro-4H-chromen-5-one.

Project description:The title compound, C16H15N3O6, is asymmetric with a chiral centre located in the pyran ring and crystallizes as a racemate. The six-membered carbocyclic ring adopts an envelope conformation with the central CH2 C atom as the flap. The amine N atom deviates from the mean plane of the pyran ring by 0.1365?(15)?Å. The nitro-phenyl ring is almost orthogonal to the pyran ring and the mean plane of the six-membered carbocyclic ring, the dihedral angle between their mean planes being 88.30?(7) and 87.61?(8)°, respectively. The mol-ecular structure is stabilized by an intra-molecular N-H?O hydrogen bond, which generates an S(6) ring motif. In the crystal, mol-ecules are linked via C-H?O hydrogen bonds, forming infinite bands lying parallel to (-110) and composed of alternate R 2 (2)(24) and R 2 (4)(12) graph-set ring motifs. The crystal structure is further stabilized by C-H?? inter-actions, forming a three-dimensional structure.

1',3',3'-Trimethyl-2,3-diphenyl-2,3-di-hydro-isoxazole-5(4H)-spiro-2'-indoline.

Project description:Two diastereoisomers of the title compound, C(25)H(26)N(2)O, have been prepared by cyclo-addition between 1,3,3-trimethyl-2-methyl-eneindoline and C-phenyl-N-phenyl-nitrone. The stereochemistry of the major diastereoisomer, viz. S,R/R,S, is confirmed by the X-ray analysis. The oxazole and the pyrole rings have envelope conformations. The packing is stabilized by weak C-H?? inter-actions involving the phenyl ring attached to the N atom of the oxazole and the phenyl ring of the indole fragment.

tert-Butyl 3-(8-bromo-4H,10H-1,2-oxazolo[4,3-c][1]benzoxepin-10-yl)-2-methyl-1H-indole-1-carboxyl-ate.

Project description:In the title compound, C(25)H(23)BrN(2)O(4), the seven-membered ring adopts a twisted-boat conformation. The indole ring system is planar within 0.021?(2)?Å and the ester group [-C(=O)-O-C-] is almost coplanar with it [dihedral angle = 3.0?(2)°]. The conformation of the ester group is influenced by intra-molecular C-H?O inter-actions. In the crystal structure, mol-ecules are linked into chains along the b axis by C-H?N hydrogen bonds.

Synthesis and Biological Activity of New 7-Amino-oxazolo[5,4-d]Pyrimidine Derivatives.

Project description:The synthesis of a series of novel 7-aminooxazolo[5,4-d]pyrimidines 5, transformations during their synthesis and their physicochemical characteristics have been described. Complete detailed spectral analysis of the intermediates 2-4, the N'-cyanooxazolylacetamidine by-products 7 and final compounds 5 has been carried out using MS, IR, 1D and 2D NMR spectroscopy. Theoretical research was carried out to explain the privileged formation of 7-aminooxazolo[5,4-d]pyrimidines in relation to the possibility of their isomer formation and the related thermodynamic aspects. Additionally, the single-crystal X-ray diffraction analysis for 5h was reported. Ten 7-aminooxazolo[5,4-d]pyrimidines 5 (SCM1-10) were biologically tested in vitro to preliminarily evaluate their immunological, antiviral and anticancer activity. Compounds SCM5 and SCM9 showed the best immunoregulatory profile. The compounds displayed low-toxicity and strongly inhibited phytohemagglutinin A-induced proliferation of human peripheral blood lymphocytes and lipopolysaccharide-induced proliferation of mouse splenocytes. Compound SCM9 caused also a moderate suppression of tumor necrosis factor α (TNF-α) production in a human whole blood culture. Of note, the compounds also inhibited the growth of selected tumor cell lines and inhibited replication of human herpes virus type-1 (HHV-1) virus in A-549 cell line. Molecular investigations showed that the compounds exerted differential changes in expression of signaling proteins in Jurkat and WEHI-231 cell lines. The activity of SCM5 is likely associated with elicitation of cell signaling pathways leading to cell apoptosis. The compounds may be of interest in terms of therapeutic utility as inhibitors of autoimmune disorders, virus replication and antitumor agents.
