We conducted a structure-activity relationship study to explore simplified analogues of the itraconazole (ITZ) scaffold for their ability to inhibit the hedgehog (Hh) signaling pathway. These analogues were based on exploring the effects of chemical modifications to the linker and triazolone/side chain region of ITZ. Analogue 11 was identified as the most potent compound in our first generation, with an IC50 value of 81 nM in a murine Hh-dependent basal cell carcinoma. Metabolic identification studies led us to identify truncated piperazine (26) as the major metabolite in human liver microsomes (HLMs) and an improved Hh pathway inhibitor (IC50 = 22 nM). This work verifies that continued truncation of the ITZ scaffold is a practical method to maintain potent anti-Hh activity while also reducing the molecular weight for the ITZ scaffold and achieving improved pharmacokinetic properties.

A glycal based synthesis of ( + )-bulgecinine, 3-hydroxy-2,5-dihydroxymethylpyrrolidine and 2-oxapyrrolizidin-3-ones proceeding through a common intermediate is reported. The key step in the work presented here is a two-step conversion of 4,6 di-O-benzyl-D-glucal to 2,3-dideoxy-2-tosylamido-D-glucose. This manuscript reports the first carbohydrate based approach to the synthesis of ( + )-bulgecinine and the whole sequence has been accomplished with complete stereochemical integrity without the formation of mixture of products in any of these steps.

A sustainable synthesis of 5-fluoromethyl-2-oxazoles by use of electrochemistry has been demonstrated. Hypervalent ArIF2 is generated by direct electrochemical oxidation of iodoarene ArI in Et3N center dot 5HF and mediates the fluorocyclization of N-propargylamides to 5-fluoromethyl-2-oxazoles. The stoichiometry in ArI turned out to be a key parameter in controlling the product selectivity. This electrochemical protocol provides access to fluorinated oxazoles starting from simply available N-propargylamides with yields up to 65% and offers a green alternative over conventional reagent-based approaches.

Conjugated enynes as well as cyclic nitronates are crucial building blocks for numerous natural products and pharmaceuticals. However, so far, no common and metal-free synthetic route to both conjugated enynes and cyclic nitronates has been reported. Herein, in situ NMR, labelling studies and theoretical calculations were combined to investigate the mechanism of the unusual triple bond formation towards conjugated enynes. Starting from nitroalkene dimers, first an isoxazolidine-2,5-diol derivative is formed as central intermediate. From this, enynes were generated by a combination of oxidation, dehydration, and retro 1,3-dipolar cycloaddition, whereas for nitronates a base induced intramolecular reorganization is proposed. While the product distribution could be controlled and high yields of nitronate were achieved, only medium to good yields for enynes were obtained due to polymerization losses. Nevertheless, we hope that these mechanistic investigations may provide a basis for further developments of organocatalytic or metal-free preparations of conjugated enynes and nitronates.

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.

Direct catalytic oxidation of alcohols to carboxylic acids is very attractive, but economical catalysis systems have not yet been well established. Here, we show that a pure inorganic ligand-supported chromium compound, (NH4)(3)[CrMo6O18(OH)(6)] (simplified as CrMo6), could be used to effectively promote this type of reaction in the presence of CO2. In almost all cases, oxidation of various alcohols (aromatic and aliphatic) could be achieved under mild conditions, and the corresponding carboxylic acids can be achieved in high yield. The chromium catalyst 1 can be reused several times with little loss of activity. Mechanism study and control reactions demonstrate that the acidification proceeds via the key oxidative immediate of aldehydes.

An artificial flavin system has been firstly proved to employ an N(5)-adduct for a catalytic transformation. This mode of catalysis occurs in some flavoenzymes but it is unknown in chemocatalysis, still exclusively using only C(4a)-adducts. In our report, an ethylene-bridged biomimetic flavin has been shown to participate in the Mitsunobu esterification reaction as an alternative to dialkyl azodicarboxylate. The reaction occurs via a flavin N(5)-triphenylphosphane adduct and is catalytic from the point of view of the flavin, which is regenerated by oxygen. This approach distinguishes from other catalytic Mitsunobu reaction procedures which require an extra catalytic system.
