Insights into the isotherm and kinetic models for the coadsorption of pharmaceuticals in the absence and presence of metal ions: A review.

Pharmaceuticals are a wide class of emerging pollutants due to their continuous and the increasing consumption of users. These pollutants are usually found in the real environment as mixtures alone or with metal ions. Thus, the migration risk increases, which complicates the removal of pharmaceuticals because of the combined and synergistic effects. The focus of treatment of pharmaceutical mixtures and their coexistence with metals is of considerable importance. For this purpose, adsorption has been efficie...

Cobalt-Catalyzed Alkylation of Drug-Like Molecules and Pharmaceuticals Using Heterocyclic Phosphonium Salts.

Alkylated pyridines are common in pharmaceuticals, and metal catalysis is frequently used to prepare this motif via Csp-Csp coupling processes. We present a cobalt-catalyzed coupling reaction between pyridine phosphonium salts and alkylzinc reagents that can be applied to complex drug-like fragments and for late-stage functionalization of pharmaceuticals. The reaction generally proceeds at room temperature, and 4-position pyridine C-H bonds are the precursors in this strategy. Given the challenges in select...

Investigation of pharmaceutical and personal care product interactions of soil and beets (Beta vulgaris L.) under the effect of wastewater reuse.

Although, several recent greenhouse studies are beginning to address the uptake of pharmaceuticals and personal care products (PPCPs) by a variety of crops, few studies have assessed the effects of exposure to complex, realistic wastewater effluents on uptake. Hence, in this study, a greenhouse experiment was conducted in order to study the interactions occurring exclusively between PPCPs in soil, and in the edible plant part of beets (Beta vulgaris) after exposure to treated wastewater effluent. According ...

Analysis of neurotransmitters in Daphnia magna affected by neuroactive pharmaceuticals using liquid chromatography-high resolution mass spectrometry.

Neurotransmission plays an essential role during the central nervous system (CNS) development. During the last years, several studies based on the changes produced in neurotransmitters of aquatic organisms caused by pharmaceuticals have been reported. Daphnia magna, the aquatic ecotoxicological model organism, shares several of the neurotransmitters targeted by antidepressant and other neuro-active drugs with vertebrates. Therefore, a method based on liquid chromatography coupled to high-resolution mass spe...

The accessibility of data on environmental risk assessment of pharmaceuticals - are environmental risk assessments information on emissions with respect to international and European environmental information law?

In the pharmaceutical sector, the right of access to environmental information is in most cases not feasible as the authorisation holders refer to commercially/industrial confidential information (CCI). However, CCI can not refuse access to environmental risk assessments (ERAs) if ERAs are to be classified as information on emissions. Pharmaceuticals inevitably enter the environment as a consequence of their intended use. This release is calculated in the ERA as predicted environmental concentration when a ...

Cell-based assays as an alternative for the study of aquatic toxicity of pharmaceuticals.

An increasing number and amount of pharmaceuticals for human and veterinary use currently reach the aquatic environment, and the determination of their effects on aquatic organisms becomes of major importance. The 96-h fish lethal test is one of the conventional assays required for environmental hazardous assessment, but it is extremely time-consuming and costly, and it raises ethical concerns. In a broad study, we compared the ability of cell-based assays to detect, in absolute terms, lethal toxicity in fi...

Reductive sp-sp Coupling Reactions Enable Late-Stage Modification of Pharmaceuticals.

Late-stage derivatization of pharmaceutically relevant scaffolds relies on the availability of highly functional-group tolerant reactions. Reactions that increase the sp character of molecules enable the pursuit of more selective and well-tolerated pharmaceuticals. Herein, we report the use of sp-sp cross-electrophile reductive couplings to modify a generic ATP-competitive kinase inhibitor with a broad range of primary and secondary alkyl halide coupling partners.

Hydrolytic stability of selected pharmaceuticals and their transformation products.

The fact that pharmaceuticals are present in the environment has been proven in numerous publications. Nevertheless, their transformation products (mainly metabolites) are detected significantly less often, mainly because they are not included in the detecting methods, even though many of them are excreted from organisms at high rates and may be biologically active or have other properties that make them a potential threat to the environment. One of the most common processes that occur in the aqueous enviro...
