There has been a lot of interest in quantification of the amorphous content of materials, especially when the amorphous content is a small percentage of the total mass. Whilst there has been success in studies on single materials, there has been little work showing how quantification of the amorphous content of one material can be undertaken in the presence of another. In this work isothermal microcalorimetry...
Cationic lipid polyamine amides (cholan-24-amides) have been prepared from chenodeoxycholic (3α,7α-dihydroxy), ursodeoxycholic (3α,7β-dihydroxy), and deoxycholic (3α,12α-dihydroxy) bile acids (5β-cholanes) by acylation of tri-Boc protected spermine. Their relative binding affinities for calf thymus DNA were determined using an ethidium bromide displacement assay. These lipopolyamine amides are synthetic...
