Synthesis of endoperoxides by domino reactions of ketones and molecular oxygen
(Royal Soc Chemistry, Cambridge, 2015)
Domino reactions of ketones with molecular oxygen in the presence of potassium hydroxide and potassium t-butoxide afford cyclic hydroperoxy acetals (3,5-dihydroxy-1,2-dioxanes). Mixed endoperoxides can also be obtained in ...
Anion-pi interactions in protein-porphyrin complexes
(Royal Soc Chemistry, Cambridge, 2015)
In this work, we have analyzed the influence of anion-pi interactions on the stability of high resolution protein-porphyrin complex crystal structures. The anion-pi interactions are distance and orientation dependent. ...
Morphological and crystallographic characteristics of electrodeposited lead from a concentrated electrolyte
(The Royal Society of Chemistry, 2013)
Electrodeposition of lead from a concentrated nitrate solution was examined by scanning electron microscopy (SEM) and by X-ray diffraction (XRD) analysis of the obtained powder particles. Single crystals of the (111) ...
Fulleropyrrolidines derived from dioxa- and trioxaalkyl-tethered diglycines
(Royal Soc Chemistry, Cambridge, 2015)
Two different alpha,omega-diglicynes linked by linear polyoxaalkyl chains in the presence of formaldehyde underwent Prato reaction to the fullerene C-60. The shorter linker templated formation of only cis-bisadducts, while ...
Synthesis, characterization and in vitro cytotoxic activities of new steroidal thiosemicarbazones and thiadiazolines
(Royal Soc Chemistry, Cambridge, 2016)
A series of new steroidal mono- and bis(thiosemicarbazones) (2a-e and 3a-e) and corresponding mono- and bis(1,3,4-thiadiazolines) (4a-e and 5a-e) was synthesized, characterized and evaluated for their anticancer activity. ...
Platinum electrocatalyst supported on glassy carbon: a dynamic response analysis of Pt activity promoted by substrate anodization
(The Royal Society of Chemistry, 2014)
In previous investigations the physicochemical state of electrochemically activated glassy carbon (GC) has been found to affect the electrochemical activity of GC-supported Pt particles. It has been assumed that carbon ...
A theoretical study on borenium ion affinities toward ammonia, formaldehyde and chloride anions
(Royal Soc Chemistry, Cambridge, 2015)
Various borenium ion affinities toward three ligands (L' = NH3, HCHO and Cl-) have been evaluated by DFT calculations in the gas-phase and in solvent (CH2Cl2). The gas-phase results have been rationalized on the basis of ...
Substituent effects on cyclic electron delocalization in symmetric B- and N- trisubstituted borazine derivatives
(Royal Soc Chemistry, Cambridge, 2013)
Aromaticity is an important concept in chemistry, useful to rationalize structure, physical properties and chemical behaviour of molecules. Aromaticity of an inorganic relative of benzene, borazine, has been the topic of ...
Energy decomposition analysis of gauche preference in 2-haloethanol, 2-haloethylamine (halogen = F, Cl), their protonated forms and anti preference in 1-chloro-2-fluoroethane
(Royal Soc Chemistry, Cambridge, 2015)
2-Haloethanol and 2-haloethylamine (halogen = F, Cl) prefer gauche conformation. This preference is significantly increased upon protonation. Commonly used explanations are based on intramolecular hydrogen bonding and ...
Phycocyanobilin, a bioactive tetrapyrrolic compound of blue-green alga Spirulina, binds with high affinity and competes with bilirubin for binding on human serum albumin
(Royal Soc Chemistry, Cambridge, 2015)
Human serum albumin (HSA) is an important regulator of the pharmacokinetic properties of bioactive compounds. Phycocyanobilin is a blue tetrapyrrole chromophore of C-phycocyanin with proven health-promoting activities. ...
