Synthesis, Biological Evaluation, and Molecular Docking of Combretastatin and Colchicine Derivatives and their hCE1-Activated Prodrugs as Antiviral Agents.

Recent studies indicate that tubulin can be a host factor for vector-borne flaviviruses like dengue (DENV) and Zika (ZIKV), and inhibitors of tubulin polymerization such as colchicine have been demonstrated to decrease virus replication. However, toxicity limits the application of these compounds. Herein we report prodrugs based on combretastatin and colchicine derivatives that contain an ester cleavage site for human carboxylesterase, a highly abundant enzyme in monocytes and hepatocytes targeted by DENV.

Electrochemical treatment of anti-cancer drug carboplatin on mixed-metal oxides and boron doped diamond electrodes: Density functional theory modelling and toxicity evaluation.

This study represents the electrooxidation of anti-cancer drug carboplatin (CrbPt) with different mixed metal oxide (MMO) and boron doped diamond (BDD) electrodes. The most effective anode was found as Ti/RuO with the complete degradation of CrbPt in just 5min. The effect of applied current density, pH and electrolyte concentration on CrbPt degradation has been studied.

Marginally designed new profen analogues have the potential to inhibit cyclooxygenase enzymes.

The current structure-activity relationship of profens (i.e., 2-arylpropionic acid derivatives, a class of non-steroidal anti-inflammatory drugs) discusses the importance of α-monomethyl substitution on these compounds, since the activities obtained through their corresponding arylacetic acid derivatives (i.

Experimental study of humic acid degradation and theoretical modelling of catalytic ozonation.

The efficiency of TiO2 as a catalyst in the ozonation of humic acid (HA) was evaluated in a comprehensive manner. Ozonation, catalytic ozonation and adsorption experiments were conducted using both synthetic HA solution and natural water. HA degradation was evaluated in terms of DOC, VIS400 and UV254.

A novel example of double 6-exo-trig heterocyclization: nitrile conversion to new anticancer active (HeLa cells) primary amine ionic liquids.

Conversion of nitriles under mild conditions leads to a new class of primary amines, including room temperature ionic liquids, acting as efficient anticancer agents.

[Investigation of the efficacy of electrolyzed acid water on the standard strains of some pathogenic microorganisms].

Many of the studies have indicated that electrolyzed acid water (EAW) has a strong microbicidal activity. In this study, EAW was obtained by the exposure of NaCl (10 g/L) and tap water mixture to direct electric current (2 ampere) during 15 minutes, in an instrument designed by the study group. EAW was tested for its inactivation efficacy on the standard strains of Staphylococcus aureus, Candida albicans and Pseudomonas aeruginosa in different concentrations and for different periods (0, 10, 30 and 60 seconds).
