In the mononuclear title complex, [Mg(C(12)H(8)N(2))(H(2)O)(4)](C(8)H(5)Cl(2)O(2))(2), each Mg(II) ion is hexa-coordinated by two N atoms from a 1,10-phenanthroline ligand [Mg-N = 2.233 (2) Å] and four water mol-ecules [Mg-OW = 2.033 (2) and 2.043 (1) Å] in a distorted octa-hedral geometry. A twofold rotation axis passes through the Mg atom. In the crystal structure, the cations and anions are linked by inter-molecular O-H⋯O hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance = 3.804 (2) Å] into layers parallel to the ac plane.

N-acyl l-homoserine lactones are signaling molecules used by numerous bacteria in quorum sensing. Some bacteria encode lactonases, which can inactivate these signals. Lactonases were reported to inhibit quorum sensing-dependent phenotypes, including virulence and biofilm.

Herein we report a cobalt-catalyzed hydroglycosylation of terminal alkynes, employing bench-stable ortho-iodobiphenyl (oIB) substituted sulfides as glycosyl donors. This reaction occurs with high stereo- and regioselectivity to afford E-configured vinyl α-C-glycosides, a class of compounds nontrivial to access by previous methods. The use of a bis(oxazoline) ligand with bulky side chains is critical for the high selectivities observed.

A series of eight gold(I) N-heterocyclic carbene (NHC) complexes [Au(IMes)(HLn)] based on 1,3-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene (IMes) and 7-azaindole derivatives (HLn), where n = 1-8 for HL1 = 5-flouro-7-azaindole, HL2 = 5-bromo-7-azaindole, HL3 = 3-chloro-7-azaindole, HL4 = 3-iodo-7-azaindole, HL5 = 5-bromo-3-chloro-7-azaindole, HL6 = 5-bromo-3-iodo-7-azaindole, HL7 = 4-chloro-2-methyl-7-azaindole and HL8 = 7-azaindole, was prepared, characterised and studied for their in vitro anti-cancer and anti-inflammatory effects. The complexes showed significant cytotoxicity on human ovarian cancer cell lines (A2780, IC ≈ 8-19 μM and A2780R, IC ≈ 8-19 μM) and lowered toxicity in normal HaCat and MRC-5 cells. Cellular effects of the selected complexes 1 and 7 were evaluated in A2780 cells using flow cytometry.

Hundreds of new flame retardants (NFRs) are widely used, causing environmental pollution and threating human health. In this study, based on the interaction of NFRs and human serum albumin (HSA), we assessed the differences in potential human accumulation of 8 NFRs including 1,2-Dibromo-4-(1,2-dibromoethyl)cyclohexane (TBECH), tetrabromobisphenol A bis(dibromopropyl ether) (TBBPA-DBPE), 2,4,6-tribromophenol (TBP), pentabromophenol (PBP), tri-n-butyl phosphate (TnBP), triphenyl phosphate (TPP), Tri(2-chloroethyl) phosphate (TCEP), and Tri(1,3-dichloro-2-propyl) phosphate (TDCP). All NFRs could bind to HSA and cause slight damage to its structure, suggesting their potential human accumulation ability.
