Photochemical Approaches to Complex Chemotypes: Applications in Natural Product Synthesis. [PDF]
The use of photochemical transformations is a powerful strategy that allows for the formation of a high degree of molecular complexity from relatively simple building blocks in a single step. A central feature of all light-promoted transformations is the

Calmodulin in Complex with Proteins and Small Molecule Ligands: Operating with the Element of Surprise. Implications for Structure-Based Drug Design [PDF]
Calmodulin plays a role in several life processes, its flexibility allows binding of a number of different ligands from small molecules to amphiphilic peptide helices and proteins. Through the diversity of its functions, it is quite difficult to find new

Stereoselective Synthesis of 2-(2-Aminoalkyl)- and 1,3-Disubstituted Tetrahydro-1H-pyrido[4,3-b]- Benzofuran and Indole Derivatives [PDF]
The addition of an allenyl indium intermediate to chiral N-tert-butanesulfinyl imines 7 proceeds with high levels of diastereocontrol. The resulting homopropargylic amine derivatives 10 were transformed into 2-(2-aminoalkyl)benzofuran and indole ...

Bisindoles : synthesis and reactions
In this thesis, synthesis of various bisindoles have beendeveloped.2,3-Bis-(3-indolyl) succinic acid derivatives wereobtained via iodine promoted coupling of the trianion ofindole-3-acetic acid (IAA) or from the dianion of themethylester of IAA. These compounds were converted to2,3-bis(3-indolyl) maleimides (arcyriarubin analogues) by DDQoxidation ...

Bis-Indole Derivatives as Dual Nuclear Receptor 4A1 (NR4A1) and NR4A2 Ligands
Bis-indole derived compounds such as 1,1-bis(3′-indolyl)-1-(3,5-disubstitutedphenyl) methane (DIM-3,5) and the corresponding 4-hydroxyl analogs (DIM8-3,5) are NR4A1 ligands that act as inverse NR4A1 agonists and are potent inhibitors of tumor growth. The
