Herein, we have developed a novel heterogeneous catalytic system for synthesis of bis(indol-3-yl)methanes using one dimensional (1D) CdS nanorods. CdS nanorods were synthesized by a solvothermal reaction technique at 200 °C over 12 h in the presence of ethylenediamine as a solvent. The prepared 1D CdS was characterized using various spectroscopic methods. X-ray diffraction (XRD) revealed the formation of highly crystalline CdS having a wurtzite structure. FESEM analysis confirms the formation of a rod like morphology with length around 150 to 200 nm and diameter â¼15 nm. TEM also validates the formation of uniform size one dimensional (1D) CdS nanostructures. The catalytic activity of 1D CdS as a Lewis acid was investigated for the synthesis of bis(indol-3-yl)methanes (BIMs) with various substituted aldehydes and indoles within shorter reaction time affording the corresponding product in excellent yield.

Disclosed herein are compounds capable of inducing apoptosis through promoting Nur77 interaction with Bcl-2 and through modulating mitochondrial activities. Also disclosed herein are compositions and methods using these compounds and compositions. Nur77 is a key regulator of Bcl-2 activities and is capable of converting Bcl-2 from an anti-apoptotic protein to a pro-apoptotic protein. Small molecules that directly modulate the Nur77/Bcl-2 apoptotic pathways are promising for treating diseases with abnormal levels of Bcl-2, Nur77, or combinations thereof, including cancers.

Kinetictarget-guidedsynthesis (KTGS) is a powerful screening approach that enables identification of small molecule modulators for biomolecules. While many KTGS variants have emerged, a majority of the examples suffer from limited throughput and a poor signal/noise ratio, hampering reliable hit detection. Herein, we present our optimized multifragment KTGS screening strategy that tackles these limitations
Synthesis of α-acylamino-amide-bis (indolyl) methane heterocycles by sequential one pot condensation-Ugi/Passerini reactions and their antimicrobial evaluation
New bis (indolyl) methane based heterocycles were developed by a proficient sequential synthesis in one pot where substituted aromatic aldehydes, isocyanides were varied, producing a library of benzamide and benzoate analogues with multiple points of diversity. The synthesized analogues were tested for their antibacterial potency against gram positive and gram negative pathogenic bacteria. (C) 2015 Published by Elsevier Ltd.
