Development of new spiro[1,3]dithiine-4,11′-indeno[1,2-b]quinoxaline derivatives as S. aureus Sortase A inhibitors and radiosterilization with molecular modeling simulation
Three groups of non-camptothecin compounds with four to five fused rings have been designed and synthesized. Their in vitro anti-proliferative activity has been evaluated with five different cancer cell lines (HCT116, PC3, U87MG, HepG2, SK-OV-3). Compounds B-2 and B-3 showed the most potent cell growth inhibition with IC50 of 169 nM and 325 nM against U87MG cell line correspondingly.

c-JunN-terminalkinase (JNK) plays a central role in stress signaling pathways implicated in important pathological processes, including rheumatoid arthritis and ischemia-reperfusion injury. Therefore, inhibition of JNK is of interest for molecular targeted therapy to treat various diseases. We synthesized 13 derivatives of our reported JNKinhibitor 11H-indeno[1,2-b]quinoxalin-11-one oxime and evaluated

A formal diastereoselective 1,3-dipolarcycloaddition of azomethine ylide and coumarin derivatives to construct coumarin based spiro multi heterocyclics has been described. The in situ generation of azo-ylide was achieved for various heterocyclic carbonyls (indenoquinoxaline and isatin). This transformation is also suitable for maleimide dipolarophiles for the synthesis of hydro-maleimide derivatives
