Synthesis and antitumor activity of 5-trifluoromethyl-2,4- dihydropyrazol-3-one nucleosides.
2,4-Dihydropyrazole glucosides 3a-3c were prepared and tested for their antitumor activity. The structures of these compounds were established by (1)H and (13)C-NMR spectroscopy. Glucoside 3b shows an in vitro IC(50) value of 16.4 muM against proliferation of the human promyelotic leukemia (HL60) cell line.

In the title compound, C(12)H(10)Br(2)O(3), the dihedral angle between the furan-5(2H)-one ring and the benzene ring is 1.2 (3)°. Two intra-molecular C-H⋯O inter-actions occur in the mol-ecule, both of which generate S(6) rings. The bromo-ethyl fragment is disordered over two sets of sites in a 0.773 (8):0.227 (8) ratio. In the crystal, inversion dimers linked by pairs of C-H⋯π inter-actions oc...
متن کامل3-Acetyl-2-methyl-4-(pyridin-3-yl)-1,4-dihydroindeno[1,2-b]pyridin-5-one
In the title compound, C20H16N2O2, the condensed tricyclic fragment is near to planar, with an r.m.s. deviation of 0.0531 Å. The 1,4-di-hydro-pyridine (1,4-DHP) ring adopts a slightly puckered boat-like conformation. The N and opposite C atoms deviate from the least-squares plane of the four other ring atoms by 0.039 (3) and 0.141 (3) Å, respectively. The C=O group located at the tricyclic frag...
متن کاملCyclohexanespiro-2′-[2′,3′,6′,7′-tetrahydro-1′H-cyclopenta[d]pyrimidin]-4′(5′H)-one
The title compound, C(12)H(18)N(2)O, was synthesized by the reaction of cyclo-hexa-none and 2-amino-cyclo-pent-1-enecarbonitrile. In the mol-ecule of the title compound, the six-carbon ring displays a chair conformation, the six-membered 1,3-diaza ring and the cyclo-pentene ring both assume envelope conformations. Supra-molecular aggregation is achieved by N-H⋯O hydrogen bonds.
