The present invention relates generally to selected fused pyrrolocarbazoles, including pharmaceutical compositions thereof and methods of treating diseases therewith. The present invention is also directed to intermediates and processes for making these fused pyrrolocarbazoles.
Palladium-catalyzed aerobic oxidative coupling of enantioenriched primary allylic amines with sulfonyl hydrazides leading to optically active allylic sulfones
A range of highly enantioenriched primary allylic amines underwent palladium-catalyzed oxidative coupling with sulfonyl hydrazides open to air at room temperature to give structurally diverse allylic sulfones in moderate to excellent yields with excellent retention of ee.

used to treat type-II diabetes mellitus, but also linked to several harmful effects. Therefore, it is essential to explore new and nontoxic antidiabetic agents with additional antioxidant properties. In this connection, a series of new N-sulfonohydrazide substituted indazoles 1-19 were synthesized by multistep reaction scheme and assessed for in vitro α-amylase inhibitory and radical (DPPH and ABTS)

The α-effect can be used as an effective means to promote iminiumion catalysed transformations, providing acyclic scaffolds to aid in catalyst design. A thorough investigation of the structure–activity relationship of the catalyst architecture reveals optimal substituents of a disubstituted carbamate and a secondary alkyl group around a hydrazine scaffold. Molecular modelling investigations provide
A new set of quinazolinedione sulfonamide derivatives as competitiveAMPAreceptorantagonist with improved properties compared to 1 is disclosed. By modulating physico-chemical properties, compound 29 was identified with a low ED50 of 5.5 mg/kg in an animal model of anticonvulsant activity after oral dosage.
