and physiologically acceptable salts thereof, are inhibitors of serine/threonine and tyrosine kinase activity. Several of the kinases whose activity is inhibited by these compounds are involved in immunologic, hyperpro;iferative or angiogenic processes. Thus, these compounds can ameliorate disase states where angiogenesis or endothelial cell hyperproliferaton is a factor. These compounds can be used to treat cancer, hyperproliferative disorders, rheumatoid artheritis, disorders of the immune system, transplant rejection, and inflammatory disorders.

2-Aryloxybenzaldehydes and 2-(arylthio)benzaldehydes undergo reductive etherification in presence of 5 mol% In(OTf)3 and stoichiometric amount of Et3SiH under solvent free conditions to generate novel symmetrical dibenzyl ethers and thioethers in excellent yields. In(OTf)3 is found to be superior in terms of catalytic activity over the other metal triflates tested for the reaction. Xanthenes and thioxanthenes

cysteine-functionalized magnetic nanoparticles ([email protected]). This nanocatalyst was characterized using various techniques such as FT-IR, XRD, TEM, SEM, EDX, VSM, and ICP. The application of catalyst ([email protected]) was investigated for O-arylation and N-arylation reactions. This phosphine-free complex was found as highly efficient heterogeneous catalyst in green media and mild reaction conditions. In addition
