A survey of Lewis acids was conducted to facilitate the formation of arylidenethiohydantoins. The use of indium(III) triflate shows significant advantages in facilitating this reaction. In most examples, the Lewis acid promoted catalysis gave shorter reaction times, higher conversion, and better purity profiles as compared to the traditional uncatalyzed reactions.

technologies to prepare these compounds. In recent years, the interest in roomtemperatureionicliquids is increasing as green reaction media for synthetic organic chemistry." In continuation of our interest in using ionicliquids as eco-friendly medium and catalyst for the condensation reactions,' we report herein l,3-dihydroindol-2-one could be reacted with aromatic aldehydes smoothly in the functional

Next, the inhibitory activity against P. falciparum of 18 compounds were tested, founding six compounds with IC50 < 20 µM. The most active of these compounds was 8c; however, their unsaturated derivative 7c was inactive. Then, a structure-activity relationship analysis was done, founding that focused LUMO lobe on the specific molecular zone is related to inhibitory activity against P. falciparum.

approximately 30% of acute myeloid leukemia (AML) patients. In the current study, the oxindole chemotype is employed as a structural motif for the design of new FLT3 inhibitors as potential hits for AML irradiation. Cell-based screening was performed with 18 oxindole derivatives and 5a–c inhibited 68%–73% and 83%–91% of internal tandem duplication (ITD)-mutated MV4-11 cell growth for 48- and 72-h treatments while
