Antibody raised against antigen in the...

(R)-α-Biphenylsulfonylamino 2-methylpropyl phosphonates attain nM potency against several MMPs and are the most effective inhibitors based on phosphonate as zinc binding group. Since their preparation by direct N-acylation of expensive, enantiopure, α-aminophosphonic acids proceeds in low yiel...

In the present study o-phenylenediamine and naphtene-1-acetic acid/2-naphthoxyacetic acid were used as a starting material through a series of steps and 2-(naphthalen-1-ylmethyl/Naphthalen-2-yloxymethyl)-1H-benzimidazol-1-yl]acetohydrazide 5a, 5b were obtained. In the first series 1,3,4-oxadiazo...

Here we describe the synthesis and the antifibrotic and anticancer activity determination of amino(imino)thiazolidinone derivatives.

Enantiomerically pure C1 and C2-symmetric bidentate N,N- and N,P-ligands are accessible from (+)-camphor in good yields (60–90%). Modified syntheses of precursors 1 and 2 are disclosed as well as the crystal structures of three hydroxy-pyrazoline intermediates. Ligands 3, 4, 6, and 11 were full...

The synthesis of new chiral spirocyclic triazolium salts, derived from (1S)-fenchone and (1R)-camphorquinone, are described. These salts, which are N-heterocyclic carbene precatalysts, were successfully employed in the catalytic asymmetric benzoin condensation affording acyloins with good yields...

The energy density of the lithium-ion capacitors are restricted by the low charge-storage capability of the capacitive electrodes. Fast redox reactions from the redox-active aqueous electrolytes can effectively boost the charge storage of the capacitive electrodes without sacrificing the power p...
