Novel camphane-based anti-tuberculosis agents with nanomolar activity
European Journal of Medicinal Chemistry, 2013A series of new amidoalcohols and amidodiols were designed on the base of the camphor scaffold and evaluated for their in vitro activity against Mycobacterium tuberculosis H37Rv and MDR strain 43. Some of the new compounds show 25 times higher activity than the classical anti-TB drug ethambutol.

Design of novel camphane-based derivatives with antimycobacterial activity
Journal of Molecular Graphics and Modelling, 2014Although tuberculosis (TB) continues to be one of the leading infectious disease killers globally, it is curable and preventable. Despite the existence of safe, well tolerated and effective drugs used in the TB treatment, the interest in new entities, combinations and regimens increases during the last 10 years. Recently, we reported for a new class of

Vibrational Absorption and Circular Dichroism Studies of (−)-Camphanic Acid
The Journal of Physical Chemistry A, 2007Vibrational absorption and circular dichroism (VCD) spectra of (-)-(1S,3R)-camphanic acid have been measured in deuterated chloroform solutions at different concentrations (0.005, 0.045, and 0.200 M) in the mid-infrared spectral range. Experimental spectra have been compared with the density functional theory (DFT) absorption and VCD spectra ...

Synthesis of New Camphane-Type Amides: Potential Synthetic Adaptogenes
Russian Journal of General Chemistry, 2019A significant effect of the steric factor on the activity of 3,5-dimethyl-1H-pyrazolide as an acylating agent has been found using the example of acylation of camphane-type monoamines. The predominant contribution of the catalytic hydrogenation as a component of the Schwenk-Papa reaction has been confirmed by the synthesis of 4-chlorobenzoyl ...

CD SPECTRA OF DIASTEREOMERIC α-ARYLETHYLAMIDES OF (–)-CAMPHANIC ACID
Spectroscopy Letters, 2002ABSTRACT CD spectra of diastereomeric α-arylethylamides 2,3, 4,5 and 6,7 exhibit nearly enantiomorphic CD curves. Interchromophoric charge-transfer interaction between the aromatic and the amide chromophore is observed only in the amide nπ* band region.
