Simultaneous Determination by Selective Esterification of Trimellitic, Phthalic, and Maleic Anhydrides in the Presence of Respective Acids

Trimellitic, phthalic, and maleic anhydrides are important building blocks to produce polymers and additives, such as plasticizers. In humans, the exposure to these compounds can cause several health issues.

Comparing Beta-lLctamase Inhibition Activity of Phthalic Acid Derivatives [PDF]

, 2018
As a Cell and Molecular major with a Pre-Pharmacy emphasis, medicine has been an interest of mine. The major cause of increasing bacterial resistance to beta-lactam antibiotics is due to the expression of the enzyme beta-lactamase in bacteria. This leads

Salts of the anti-HIV drug lamivudine with phthalic and salicylic acids [PDF]

, 2012
Salts of the anti-HIV drug lamivudine, with phthalic acid and salicylic acid as counterions, were investigated in this study. Neither the packing of the (lamivudine)(+)(phthalic acid)(-) ion pairs nor the conformation of the lamivudine moiety itself were

Aqueous dissociation constants of bile pigments and sparingly soluble carboxylic acids by 13C NMR in aqueous dimethyl sulfoxide: effects of hydrogen bonding

Journal of Lipid Research, 1997
pKas for the acid dissociation of the carboxyl groups of bilirubin in water have been reported recently to be 8.1-8.4, or higher. These high values were attributed to intramolecular hydrogen bonding.

Phthalic acid mimics 17β-estradiol actions in WISH cells

, 2001
The object of this study was to evaluate whether phthalic acid, which is one of the metabolites of phthalic acid esters, exerts estrogenic actions in WISH cells, an immortalized cell line derived from human amniotic tissue.

Replacement of dietary saturated fatty acids by trans fatty acids lowers serum HDL cholesterol and impairs endothelial function in healthy men and women [PDF]

, 2001
We tested whether trans fatty acids and saturated fatty acids had different effects on flow-mediated vasodilation (FMD), a risk marker of coronary heart disease (CHD). Consumption of trans fatty acids is related to increased risk of CHD, probably through
