A series of new ureidoindolin-2-one derivatives were synthesized and evaluated as inhibitors of receptor tyrosine kinases. Investigation of structure-activity relationships at positions 5, 6, and 7 of the oxindole skeleton led to the identification of 6-ureido-substituted 3-pyrrolemethylidene-2-oxindole derivatives that potently

ret-derived oncogenes are frequently and specifically expressed in thyroid tumors. In contrast to the ret receptor, ret oncoproteins are characterized by ligand-independent tyrosine-kinase activity and tyrosine phosphorylation. In this study, novel synthetic arylidene 2-indolinone compounds were evaluated as inhibitors of

During the past five years, several members of the KCNQ potassium channel gene family have been identified with a high degree of CNS specificity. Within the KCNQ family, the combination of the KCNQ2/KCNQ3 proteins, and the KCNQ5/KCNQ3 arrangement has been
An asymmetric organo- and gold-catalyzed one-pot sequential Mannich/hydroamination reaction has been developed. Using this protocol, spiro[pyrrolidin-3,2'-oxindole] derivatives were synthesized in good yields (up to 91%) and excellent enantioselectivities (up to 97% ee).

An efficient palladium-catalyzed protocol for the synthesis of 3-arylidene-2-oxindoles has been developed. In this approach, a sequential one-pot six-component reaction via Ugi/Heck carbocyclization/Sonogashira/nucleophilic addition was used for the synthesis of the desired skeleton.
