Chemical Study on Haematoxylon campechianum: a Sweet Principle and New Dibenz(b,d)oxocin Derivatives.

Chemical and Pharmaceutical Bulletin, 1991
The sweet principle of an extract of heartwood of Haematoxylon campechianum was identified s hematoxylin (1), the well-known staining reagent already isolated from this plant. In addition to 1, two new dibenz[b, d]oxocim derivatives (2 and 3) were obtained.

Novel approaches to medium rings, enantiomerically enriched alcohols and haloalkynes [PDF]

, 2012
Medium rings (8-12 atoms) are present in many naturally occurring molecules which in many cases have potentially useful biological activity. Unfortunately current synthetic methods to synthesise medium rings lack general applicability or require high ...

Theoretical analysis of biological activity of a new oxocin-steroid derivative against aromatase enzyme using a docking model

, 2018
Several aromatase inhibitors have been prepared for treatment of breast cancer; however, the site of interaction with enzyme surface is not very clear. Therefore, the objective of this investigation was to synthesize and analyze the theoretical activity of a new oxocin-steroid derivative against aromatase (2dw3 protein) in a docking model using some ...

Flow system for heterocyclic synthesis [PDF]

The potential of the silver-catalysed cyclisation has been illustrated by the synthesis of furans, pyrroles and pyrazole-N-oxides. With yields predominantly being >95%, and ubiquitous high purity, the results herein show the compatibility of many ...
