Tautomeric stabilities of 4-fluorohistidine shed new light on mechanistic experiments with labeled ribonuclease A
(Elsevier B.V., 2016-12-01)Ribonuclease A is the oldest model for studying enzymatic mechanisms, yet questions remain about proton transfer within the active site. Seminal work by Jackson et al. (1994) labeled Ribonuclease A with 4-fluorohistidine, ... -
Thallium(I) complexes of cyano-substituted bispyrazolylborate ligands
(Springer, 2012-07)Two thallium scorpionate complexes: dihydrobis(3-phenyl-4-cyanopyrazolyl)boratothallium(I) (TlBp(Ph,4CN)), C20H14BN6Tl and dihydrobis(3-tert-butyl-4-cyanopyrazolyl)boratothallium(I) (TlBp (t-Bu,4CN)), C16H22BN6Tl have been ... -
The development of methods to separate and identify variant lipid isomers, utilizing FAIMS and other technologies
(Wichita State University, 2018-05)The development of lipidomics has accelerated over the last decade. However, one of the major sticking points for true identification of individual lipids is the existence of isomers. Due to the complex range of possible ... -
The preparation of some new azo derivatives of guaiacol I

The preparation of some new azo derivatives of guaiacol II
(Wichita State University, 1934-06)In this investigation a number of dyes have been prepared by coupling guaiacol with various diazotized amines. Some of the physical properties of these compounds have determined. In all cases the sodium salt of the ... -
The reduction of omega-nitrostyrene
(Wichita State University, 1947-07)A survey of the literature reveals that a good general method for the preparation of arylacetaldehydee is desirable. Since omega-nitrovinylaryl compounds are readily prepared from nitromethane and arylaldehydes, the ... -
The role of the 90 kDa palladin in the regulation of actin filaments
(Wichita State University, 2020-05)Metastasis is the most clinically significant step in cancer progression. Migration and metastasis are not fully understood, but it is clear that the actin cytoskeleton plays an essential role. Palladin is specifically ... -
The syntheses of penicillamine and penicillamine derivatives
(Wichita State University, 1948-12)The purpose of this investigation was to attempt the syntheses of penicillamine and penicillamine derivatives in a more practical manner than heretofore done, and to investigate some of the conditions necessary for the ... -
Thermal switch using controlled capillary transition in heterogeneous nanostructures
(Elsevier, 2018-06)The development of a nanoscale thermal switch is a crucial step toward advanced thermal management systems including future thermal logic gates and computers. This study demonstrates a new nanoscale thermal switch mechanism ... -
Through-bond photoinduced electron transfer in a porphyrin-fullerene conjugate held by a Hamilton type hydrogen bonding motif
(The Royal Society of Chemistry, 2009-03-21)Control over the occurrence of through-bond electron transfer in self-assembled donor-acceptor conjugates is often difficult, since through-space electron transfer also competes due to the flexible nature of the spacer ... -
Time-dependent density functional theory study of the spectroscopic properties related to aggregation in the platinum(II) biphenyl dicarbonyl complex
(American Chemical Society, 2003-12-01)Singlet ground-state geometry optimization of the monomer, four dimers, and the trimer of [Pt(bph)(CO)(2)], where bph = biphenyl dianion, was performed at the B3LYP level of density functional theory (DFT) with a mixed ... -
To keep or not to keep? the question of crystallographic waters for enzyme simulations in organic solvent
(Taylor & Francis Group, 2016)The use of enzymes in non-aqueous solvents expands the use of biocatalysts to hydrophobic substrates, with the ability to tune selectivity of reactions through solvent selection. Non-aqueous enzymology also allows for ... -
Transport of tryptophan into SH-SY5Y neuronal cells
(Wichita State University. Graduate School., 2008-04-25)The human neuroblastoma cell line SH-SY5Y is a commonly used catecholaminergic model in studies related to neurotoxicity of various substances, oxidative stress, and neurodegenerative diseases. Specific transport of ... -
Tridentate N(2)S ligand from 2,2'-dithiodibenzaldehyde and N,N-dimethylethylenediamine: synthesis, structure, and characterization of a Ni(II) complex with relevance to Ni Superoxide Dismutase
