Factors Dictating Carbene Formation at (PNP)Ir [PDF]

open access: yes, 2010
The mechanistic subtleties involved with the interaction of an amido/bis(phosphine)-supported (PNP)Ir fragment with a series of linear and cyclic ethers have been investigated using density functional theory.

Hydrocarbon molar water solubility predicts NMDA vs. GABAA receptor modulation. [PDF]

open access: yes, 2014
BackgroundMany anesthetics modulate 3-transmembrane (such as NMDA) and 4-transmembrane (such as GABAA) receptors. Clinical and experimental anesthetics exhibiting receptor family specificity often have low water solubility. We hypothesized that the molar

A synthetic benzoxazine dimer derivative targets c‐Myc to inhibit colorectal cancer progression

open access: yesMolecular Oncology, EarlyView.
Benzoxazine dimer derivatives bind to the bHLH‐LZ region of c‐Myc, disrupting c‐Myc/MAX complexes, which are evaluated from SAR analysis. This increases ubiquitination and reduces cellular c‐Myc. Impairing DNA repair mechanisms is shown through proteomic analysis.

New [4 + 2] Cycloadditions of in situ Generated Indolyl Enol Ethers and Their Anions with Dimethyl Acetylenedicarboxylate: A One-Pot Access to 4-Alkoxy-Substituted Carbazoles

open access: yesCHIMIA, 1992
The 3-indolyl(methyl)methoxycarbenium tetrafluoroborates 1a?d were deprotonated with NaH to furnish in situ the highly reactive 3-indolyl enol ethers 2a or their corresponding 3-indolyl enol ether anions 2b.

Profiling of oligolignols reveals monolignol coupling conditions in lignifying poplar xylem [PDF]

open access: yes, 2004
Lignin is an aromatic heteropolymer, abundantly present in the walls of secondary thickened cells. Although much research has been devoted to the structure and composition of the polymer to obtain insight into lignin polymerization, the low-molecular ...

Cis‐unsaturated sphingolipids support growth of sphingoid base‐deficient yeast but impair plasma membrane integrity

open access: yesFEBS Open Bio, EarlyView.
Sphingoid base structures, the sphingolipid backbones, vary among species. We established yeast cells in which the native sphingoid base was replaced with plant‐type bases containing cis or trans double bonds. This is, to our knowledge, the first eukaryotic model mostly composed of sphingolipids containing cis‐unsaturated sphingoid base, providing a ...
