Novel substituted azole diones are provided that kill cells, suppress cell proliferation, suppress cell growth, abrogate the cell cycle G2 checkpoint and/or cause adaptation to G2 cell cycle arrest. Methods of making and using the invention compounds are provided. The invention provides substituted azole diones to treat cell proliferation disorders. The invention includes the use of substituted azole diones to selectively kill or suppress cancer cells without additional anti-cancer treatment. The invention includes the use of cell cycle G2-checkpoint-abrogating substituted azole diones to selectively sensitize cancer cells to DNA damaging reagents, treatments and/or other types of anti-cancer reagents.
synthesizing new functionalized benzo[b][1,8]naphthyridine derivatives is presented. Benzo[g][1,8]naphthyridines have been synthesized by the condensation of substituted 2-chloroquinoline-3-carbaldehydes with various 2-chloroquinoline-4-amines, 1H-Indazole-6-amine in basic medium. The electro luminescence and photophysical properties of a series of benzo[g][1,8]naphthyridines 5(a–d), 6(a–d) and 2-ch
提出了一种有效的一步合成新的功能化的苯并[ b ] [1,8]萘啶衍生物的策略。苯并[ g ] [1,8]萘啶是通过将取代的2-氯喹啉-3-甲醛与各种2-氯喹啉-4-胺,1 H-吲唑-6-胺在碱性介质中缩合而合成的。一系列苯并[ g ] [1,8]萘啶5(a–d),6(a–d)和2-氯喹啉-4-胺3(a–f)的电致发光和光物理性质为了获得良好的荧光材料而进行了报道和研究。此外,已经研究了电子给体-受体取代基对所有分子的荧光性质的影响以及它们的荧光量子产率。此外,我们通过密度泛函(DFT M06-HF)研究分析了与HOMO-LUMO相关的带隙能量。实验观察与理论计算非常吻合。所有合成的化合物均根据其NMR,质谱数据分析进行鉴定。
Regioselective synthesis of novel 2-chloroquinoline derivatives of 1,4-dihydropyridines
Highly regioselective reaction of some substituted 2,4-dichloroquinolines with symmetrical 1,4-dihydropyridines, leading to novel quinoline derivatives of DHPs, has been achieved in the presence of powdered K2CO3, as a mild and efficient base, at moderate temperature. All the synthesized compounds were characterized by use of IR, NMR, and mass spectral data.

Ultrasound-promoted reaction of substituted 2,4-dichloroquinolines (1) with ethyl 4-(3-hydroxyphenyl)-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate (2) in the presence of K2CO3 as mild base at moderate temperatures leads to 2-chloroquinolin-4-pyrimidine carboxylate derivatives (3) with high regioselectivity. All the compounds synthesized were characterized by use of spectral data and screened for their antibacterial activity against two Gram-positive (Staphylococcus aureus, Bacillus cereus) and two Gram-negative (Escherichia coli and Pseudomonas aeruginosa) bacteria. Activity was moderate.
