The molecular chaperone heat shock protein 90 (Hsp90) is a promising target for cancer therapy. Natural product aconitine is a potential Hsp90 inhibitor reported in our previous work. In this study, we designed and synthesized a series of 2-((1-phenyl-1H-1,2,3-triazol-4-yl)methyl)-2-azabicyclo[3.2.1]octan-3-one derivatives as potent Hsp90 inhibitors by simplifying and modifying aconitine scaffold. Among these compounds, 14t exhibited an excellent antiproliferative activity against LoVo cells with an IC50 value of 0.02 μM and a significant Hsp90α inhibitory activity with an IC50 value of 0.71 nM. Molecular docking studies provided a rational binding model of 14t in complex with Hsp90α. The following cell cycle and apoptosis assays revealed that compound 14t could arrest cell cycle at G1/S phase and induce cell apoptosis via up-regulation of bax and cleaved-caspase 3 protein expressions while inhibiting the expressions of bcl-2. Moreover, 14t could inhibit cell migration in LoVo and SW620 cell lines. Consistent with in vitro results, 14t significantly repressed tumor growth in the SW620 xenograft mouse model.

The reduction of cage ketoximes under Schwenk–Papa reaction conditions was studied to establish that the d,l, d- and l-camphor oximes are smoothly reduced to the corresponding amines in high yields. At the same time, d,l-norcamphor and adamantan-2-one oximes undergo partial catalytic deoximation to form a mixture of the corresponding amines and alcohols.

In this study, bornyl- and cytisine-based cyanopyrrolidines as potent dipeptidyl peptidase-IV (DPP-IV) inhibitors were synthesised. The in vitro inhibiting activities of bornyl- and cytisine derivatives towards DPP-IV were evaluated. Bornyl-based cyanopyrrolidines were shown to have moderate inhibitory activity with regard to DPP-IV (1.27–15.78 μM). A docking study was performed to elucidate the structure-activity relationship of the obtained compounds. The in vivo hypoglycemic activities of the same compounds were evaluated with the oral glucose tolerance test (OGTT) in mice. Bornyl-based cyanopyrrolidines were shown to have good hypoglycemic activity.

An acceptor-free catalysis protocol for the deoximation of ketoximes and aldoximes using RuCl3 as the catalyst has been developed. Under the optimized conditions, various oximes were converted to ketones and nitriles with excellent isolated yields.

Stereochemical Assignment of Camphoroxime by PMR Spectroscopy Using Tris(dipivalomethanato)europium(III)

, p. 33 - 35 (2007/10/02)
Stereochemistry of camphoroxime has been deciphered with the help of PMR spectroscopy using tris(dipivalomethanato)europium (III) as a shift reagent.The hydroxyl group in the oxime has been shown to be syn to γ-methyl on the basis of its anisotropic effect as well as the pronounced paramagnetic induced shift of the γ-methyl.Three methyl (α-, β- and γ-) resonances have also been rationalised using various concentrations of the shift reagent.
