The photochemistry of N-methylformamide (MF) is elucidated by investigating its photodissociation products generated by UV irradiation (248 nm) in an argon matrix (10 K). We find that, starting from trans-MF, prolonged irradiation produces cis-MF, CH3NH2 and CO fragments as major

The inability to predict if a metabolically bioactivated compound will cause toxicity in later stages of drug development or post-marketing is of serious concern. One approach for improving the predictive success of compound toxicity has been to compare the gene

Cryoprotectant toxicity is a fundamental limiting factor for the successful cryopreservation of living systems by both freezing and vitrification, and the ability to negate it would be attractive. Past attempts to demonstrate "cryoprotectant toxicity neutralization" (CTN) have had many ups

This paper presents a theoretical study of the cooperative effect in sixteen linearly-arranged trimer systems consisting of N-methylformamide dimer and an extra amino acid residue. These trimer systems, NMF-NMF-AAR, in short, have been systematically investigated by full optimization at B3LYP/cc-pVTZ

N,N-Dimethylformamide (DMF) has been widely used in industries because of its extensive miscibility with water and solvents. Its health effects include hepatotoxicity and male reproductoxicity, possibly linked with mitochondrial DNA (mtDNA) alterations including mtDNA common deletion (DeltamtDNA(4977)) and mtDNA copy

Impedance spectroscopy was used for studies of the frequency dependence of the electric conductivity of two highly conducting liquid amides: N-methylformamide (NMF), strongly self-associated via the hydrogen bonds C=O...N-H, and N,N-dimethylformamide (DMF), which is not able to self-organize by hydrogen

A number of volvocalean green algae species were subjected to a two-step cryopreservation protocol with various cryoprotectants. Potential cryoprotectants were methanol (DMSO), N,N-dimethylformamide (DMF), N,N-dimethylacetamide, N-methylformamide, and hydroxyacetone (HA). We confirmed prior reports that MeOH was effective for cryopreserving Chlamydomonas

The vibrational motions of the model peptide unit represented by the main-chain carbonyl carbon, oxygen, nitrogen, and amide hydrogen are analyzed quantum-mechanically using formamide, cis-N-methylformamide, trans-N-methylformamide, N,N-dimethylformamide, l-alanyl-l-alanine, and N-benzoylphenylalanine as dynamical models. To make this analysis computationally feasible, the
