A general and efficient method for the synthesis N-difluoroethyl imides has been developed. This copper-catalyzed four-component reaction proceeds via in-situ generated difluorodiazomethane, which does not require prior formation and transferring. The reaction is scalable, tolerant toward a range of functional groups, and also suitable for the late-stage functionalization of drugs and drug-like molecules.

A universally applicable method for the prediction of the isobaric heat capacities of the liquid and solid phase of molecules at 298.15 K is presented, derived from their true volume. The molecules’ true volume in A(3) is calculated on the basis of their geometry-optimized structure and the Van-der-Waals radii of their constituting atoms by means of a fast numerical algorithm. Good linear correlations of the true volume of a large number of compounds encompassing all classes and sizes with their experimental liquid and solid heat capacities over a large range have been found, although noticeably distorted by intermolecular hydrogen-bond effects. To account for these effects, the total amount of 1303 compounds with known experimental liquid heat capacities has been subdivided into three subsets consisting of 1102 hydroxy-group-free compounds, 164 monoalcohols/monoacids, and 36 polyalcohols/polyacids. The standard deviations for Cp(liq,298) were 20.7 J/mol/K for the OH-free compunds, 22.91 J/mol/K for the monoalcohols/monoacids and 16.03 J/mol/K for the polyols/polyacids. Analogously, 797 compounds with known solid heat capacities have been separated into a subset of 555 OH-free compounds, 123 monoalcohols/monoacids and 119 polyols/polyacids. The standard deviations for Cp(sol,298) were calculated to 23.14 J/mol/K for the first, 21.62 J/mol/K for the second, and 19.75 J/mol/K for the last subset. A discussion of structural and intermolecular effects influencing the heat capacities as well as of some special classes, in particular hydrocarbons, ionic liquids, siloxanes and metallocenes, has been given. In addition, the present method has successfully been extended to enable the prediction of the temperature dependence of the solid and liquid heat capacities in the range between 250 and 350 K.

LDH1A1, one of 19 NAD(P)(+)-dependent aldehyde dehydrogenases, participates in multiple metabolic pathways and has been indicated to play an important role in obesity and diabetes. In this study, a series of 1,3-di-methylpyrimidine-2,4-diones were designed, synthesized and evaluated as novel selective aldehyde dehy-drogenase 1A1 inhibitors. Among them, compounds 46, 50, 53, 56 and 57 exhibited excellent inhibitory activity against ALDH1A1 with IC50 values in the low nanomolar range and high selectivity over ALDH1A2, ALDH1A3, ALDH2 and ALDH3A1. Furthermore, in vitro study demonstrated that compound 57 effectively improved glucose consumption in HepG2 cells compared to compound 1 (CM026).

In patients with diabetes mellitus (DM), amputation rates exceed 30% when lower extremity osteomyelitis is present. We sought to determine the rate of osteomyelitis and any subsequent amputation in our patients with DM and lower extremity burns. We performed a single-site, retrospective review at our burn center using the institutional burn center registry, linked to clinical and administrative data. Adults (>= 18 years old) with DM admitted from January 1, 2014 to December 31, 2018 for isolated lower extremity burns were eligible for inclusion. We evaluated demographics, burn characteristics, comorbidities, presence of radiologically confirmed osteomyelitis, length of stay (LOS), inpatient hospitalization costs, and amputation rate at 3 months and 12 months after injury. We identified 103 patients with DM and isolated lower extremity burns. Of these, 88 patients did not have osteomyelitis, while 15 patients had radiologically confirmed osteomyelitis within 3 months of the burn injury. Compared to patients without osteomyelitis, patients with osteomyelitis had significantly increased LOS (average LOS 22.7 days vs 12.1 days, P = .0042), inpatient hospitalization costs (average $135,345 vs $62,237, P = .0008), amputation rate within 3 months (66.7% vs 5.70%, P < .00001), and amputation rate within 12 months (66.7% vs 9.1%, P < .0001). The two groups were otherwise similar in demographics, burn injury characteristics, access to healthcare, and preexisting comorbidities. Patients with DM and lower extremity burns incurred increased LOS, higher inpatient hospitalization costs, and increased amputation rates if radiologically confirmed osteomyelitis was present within 3 months of the burn injury.

The atom-efficient formation of amide bonds has emerged as a top-priority research field in organic synthesis, as amide bonds constitute the backbones of proteins and represent an important structural motif in drug molecules. Currently, the increasing demand for novel discoveries in this field has focused substantial attention on this challenging subject. Herein, the degradable 1,3,5-triazo-2,4,6-triphosphorine (TAP) motif is presented as a new condensation system for the dehydrative formation of amide bonds between diverse combinations of aromatic carboxylic acids and amines. The underlying reaction mechanism was investigated, and potential catalyst intermediates were characterized using(31)P NMR spectroscopy and ESI mass spectrometry.

A metal-, oxidant-, and additive-free conversion of hydroxamates to esters have been achieved using molecular iodine as the reagent using a novel but not-so-explored heron-type rearrangement. The reaction proceeds with almost equal facility with substrates having either electron-donating or electron-withdrawing substituent. Similarly, alpha,ss-unsaturated, and sterically hindered ortho-substituted hydroxamates also undergo the desired transformation smoothly.
