designed benzylindolyldiketo acids acting as potent HIV‐1 integrase strand transfer inhibitors, we disclose the results obtained with novel compounds chemically modified on the diketo acid moiety in order to investigate its influence on the biological activity and cytotoxicity. The activity of designed and synthesized 4‐[(1‐benzyl‐1H‐indol‐3‐yl)carbonyl]‐3‐hydroxyfuran‐2(5H)‐one derivatives lies in the

An efficient palladium-catalyzedC–H bond alkenylation/annulation strategy to access carboline carboxylates from indolyl ketoximes and acrylates through C–C/C–N bond formation is reported. Indolyl ketoximes not only direct ortho-olefination with acrylates, but also undergo an intramolecular N–O bond cleavage/traceless annulation to construct carboline carboxylates straightforwardly in this concise
We report herein the development of a new three-dimensional pharmacophore model for HIV-1 integrase inhibitors which led to the discovery of some 4-[1-(4-fluorobenzyl)-1H-indol-3-yl]-2-hydroxy-4-oxobut-2-enoic acids that are able to specifically inhibit the strand transfer step of integration at nanomolar concentration. The synthesis of the new designed molecules is also described. (c) 2008 Elsevier Ltd. All rights reserved.
Pharmacophore-Based Design of HIV-1 Integrase Strand-Transfer Inhibitors
Using a training set of diketo-like acid HIV-1 integrase (IN) strand-transfer inhibitors, a 3D pharmacophore model was derived having quantitative predictive ability in terms of activity. The best statistical hypothesis consisted of four features (one hydrophobic aromatic region, two hydrogen-bond acceptors, and one hydrogen-bond donor) with r of 0.96. The resulting pharmacophore model guided the rational design of benzylindoles as new potent IN inhibitors, whose microwave-assisted synthesis and biological evaluation are reported.
