Certain 1-(aromatic- or heteroaromatic-substituted-3-(heteroaromatic substituted)-1,3-propanediones are described as inhibitors of HIV integrase and inhibitors of HIV replication. These compounds are useful in the prevention or treatment of infection by HIV and the treatment of AIDS, either as compounds, pharmaceutically acceptable salts, pharmaceutical composition ingredients, whether or not in combination with other antivirals, immunomodulators, antibiotics or vaccines. Methods of treating AIDS and methods of preventing or treating infection by HIV are also described.

A compound of the formula (I):
wherein X is hydroxy, protected hydroxy or optionally substituted amino; Y is —COORA wherein RA is hydrogen or ester residue, —CONRBRC wherein RB and RC each is independently hydrogen or amide residue, optionally substituted aryl or optionally substituted heteroaryl; and A1 is optionally substituted heteroaryl; provided that a compound wherein Y and/or A1 is optionally substituted indol-3-yl is excluded, a tautomer, a prodrug, a pharmaceutically acceptable salt or a hydrate thereof has an inhibitory activity against an integrase.
unprecedented series of non-quinolone bacterial topoisomerase inhibitors from the Sanofi patrimony, named IPYs for imidazopyrazinones, as part of the Innovative Medicines Initiative (IMI) European Gram Negative Antibacterial Engine (ENABLE) organization. Hybridization of these historical compounds with the quinazolinediones, a known series of topoisomerase inhibitors, led us to a novel series of tricyclic

The first enantioselective syntheses of carbocyclic ribavirin by both convergent and linear approaches are described. The linear approach from chiralnonracemic 2-azabicyclo[2.2.1]hept-5-en-3-one proves to be a highly efficient route to carbocyclic analogs of ribavirin.
one or two metal ions within the catalytic core of the enzyme. The present work is intended as a contribution to elucidate the mechanism of action of the HIV-IN inhibitors by studying the coordinative features of H2L1 (L-708,906), an important member of the diketo acids family of inhibitors, and H2L2, a model for S-1360, another potent IN inhibitor. Magnesium(II) and manganese(II) complexes of H2L1
大多数活性和选择性链转移HIV-1整合酶(IN)抑制剂均含有螯合官能团,这些官能团对于抑制酶的催化活性至关重要。特别地,二酮酸及其衍生物可以在酶的催化核心内配位一个或两个金属离子。本工作的目的是作为一个贡献通过研究H的协调功能,以阐明HIV-IN抑制剂的作用机制2大号1(L-708906),该二酮的一个重要成员酸类家族抑制剂,和H 2 L 2是另一种有效的IN抑制剂S-1360的模型。H 2 L 1和H 2的镁(II)和锰(II)配合物分离L 2并在溶液中和固态下充分表征。通过X射线衍射分析来解析锰络合物[Mn(HL 2)2(CH 3 OH)2 ]·2CH 3 OH的晶体结构。此外,建立了H 2 L 2与镁(II)和锰(II)离子的形态模型,并测量了配合物的形成常数。M(HL 2)2(M = Mg 2 +,Mn 2+)是生理pH值溶液中最丰富的物种。测试所有合成的化合物的抗IN活性,对配体
