The title compound, C(17)H(21)N(3)O(3), has a Z configuration about the N=N double bond. The molecular conformation is stabilized by intramolecular N-H⋯O and O-H⋯N hydrogen bonds.

In the title compound, C(20)H(15)BrN(2)O(2), the C=N double bond displays a trans configuration. The crystal structure features an intra-molecular O-H⋯N hydrogen bond.

The relative stereochemistry of the 22-membered marine macrolide dictyostatin, a Taxol-like antimitotic agent, was determined based on a combination of extensive high field NMR studies, including J-based configuration analysis, and molecular modelling.

We recently demonstrated that the cytotoxicity of nineteen 1,2,3,4-tetrahydroisoquinoline derivatives depends on the molecular size (surface area, volume, width measured at 3-dimensional configuration), but not on most of the other electronic factors (Ishihara et al., Anticancer Res 29: 2265-2272, 2009). However, the information regarding cytotoxicity and molecular size in these compounds is li...

Histomorphological features of colorectal cancers (CRC) represent valuable prognostic indicators for clinical decision making. The invasive margin is a central feature for prognostication shaped by the complex processes governing tumor-host interaction. Assessment of the tumor border can be performed on standard paraffin sections and shows promise for integration into the diagnostic routine of ...

Georgia Tech, as part of DARPA's Tactical Mobile Robotics (TMR) Program, is developing a wide range of mission speciication capabilities for the urban warrghter. These include the development of a range of easily conngurable mission-speciic robot behaviors suitable for various battleeeld and special forces scenarios; communications planning and connguration capabilities for small teams of robot...

Manipulating and defining content of configuration files is one of the central tasks of configuration management tools. This is important to ensure a desired and correct behavior of computer systems. However, often considered very simple, this task can turn out to be very challenging. Configuration management tools provide different strategies for content manipulation of files, hence an adminis...

Introduction: Long bone examination in standing position, as one of the diagnostic methods in plain radiography, is most commonly used in the field of medical diagnosis, especially leg length discrepancy. However, with regard to this examination, reproductive organs are exposed to radiation as they are placed in the adjacent area to the long bone. Due to the sensitivit...
