Novel benzofuran-3-one indole inhibitors of PI3 kinase-α and the mammalian target of rapamycin: Hit to lead studies
A series of benzofuran-3-one indole phosphatidylinositol-3-kinases (PI3K) inhibitors identified via HTS has been prepared. The optimized inhibitors possess single digit nanomolar activity against p110α (PI3K-α), good pharmaceutical properties, selectivity versus p110γ (PI3K-γ), and tunable selectivity versus the mammalian target of rapamycin (mTOR). Modeling of compounds 9 and 32 in homology models of PI3K-α and mTOR supports the proposed rationale for selectivity. Compounds show activity in multiple cellular proliferation assays with signaling through the PI3K pathway confirmed via phospho-Akt inhibition in PC-3 cells.

Photochemical electrocyclisation of 3-vinylindoles to pyrido[2,3-a]-, pyrido[4,3-a]- and thieno[2,3-a]-carbazoles: Design, synthesis, DNA binding and antitumor cell cytotoxicity
In the context of the design and synthesis of DNA ligands, some new hetarene annelated carbazoles were synthesized. As lead structure the intercalating tetracyclic systems pyrido[2,3-a]- and pyrido[4,3-a]-carbazoles and in one case a thieno[2,3-a]-carbazo
Creation of new promoters for plant's root growth: its application for the syntheses of vulcanine and borreline, and for combating desertification at gobi desert in inner mongolia 1#
Abstract - Various new 2-substituted indole-3-carbaldehydes are prepared. Structurally related alkaloids, vulcanine and borreline, are synthesized as well. Among the compounds, 2-haloindole-3-carbaldehydes are found to be potent promoters of plant's root growth. Its successful preliminary application is reported for making Gobi desert in Inner Mongolia full of plant.
