a Crystal structure of a parallel signal transducer and activator of transcription 3 ( STAT3 ) dimer bound to DNA in orthogonal views. The surface structure is colored according to atom type, with oxygen in red, nitrogen in blue, sulfur in dark yellow, and carbon in either bright yellow or green depending on the protomer. The double-helix structure of DNA is colored in cyan. The crystallographic data were taken from the Protein Data Bank (PDB) file 1BG1 for the STAT3 parallel dimer . b Ribbon diagram of an anti-parallel STAT3 dimer. The α‑helical coiled-coil domains are colored in yellow, the DNA-binding domains in cyan, the linker domains in green , and the SH2 domains in red. Structural data were from the PDB file 6TLC for STAT3 . Figures b and c were created with the program <t>PyMOL</t> <t>(DeLano</t> Scientific). c Schematic model of the interleukin (IL)-6-induced JAK/STAT3 signaling pathway. Binding of IL‑6 or a related cytokine to the heterodimeric cell surface receptor triggers a series of tyrosine-phosphorylation steps catalyzed by non-covalently bound Janus kinase ( JAK ), including JAK auto-phosphorylation and receptor phosphorylation. The phosphorylated receptor tail recruits STAT3 molecules, which are then phosphorylated at a single tyrosine ( 1 ). Through spontaneous dissociation and re-association, the activated STAT3 proteins constantly oscillate between a parallel and an antiparallel dimer conformation ( 2 ). After binding to importins ( 3 ), phospho-STAT3 dimers are imported into the nucleus via nuclear pore complexes ( 4 ). In the nucleus, STAT3 proteins modulate gene expression ( 5 ) and rearrange in an antiparallel dimer conformation ( 6 ) to be dephosphorylated ( 7 )

Article Snippet: In the current work, we describe the synthesis of 1,4-dihydropyridine (1,4-DHP) derivatives via Hantzsch multicomponent reaction and their evaluation as photosystem II (PSII) inhibitors through chlorophyll a fluorescence bioassay.. Among all the compounds tested, 1,1’-(2,4,6-trimethyl-1,4-dihydropyridine-3,5-diyl)bis(ethan-1-one) (4b) showed best results, reducing the parameters performance index on absorption basis (PIabs) and electron transport per reaction center by 61% and 49%, respectively, as compared to the control.. These results indicate the inhibitory activity of PSII over the electron transport chain.
