ABSTRACT The ATP‐binding cassette transporter MDR1 P‐glycoprotein (syn. ABCB1) is an efflux carrier at the cell membrane that regulates drug absorption, distribution, and elimination. At the blood–brain barrier, MDR1 restricts brain entry of potentially neurotoxic drugs, such as ivermectin. In dogs and cats, MDR1 (syn.

Knowledge mapping of risk mitigation measures against vector‐borne diseases
Abstract A comprehensive synthesis of current evidence on surveillance, prevention and control measures for 25 selected vector‐borne diseases (VBDs) affecting animals in the EU is presented here. The assessment integrates evidence from systematic literature reviews, modelling studies, field investigations and expert judgement.

Nitroimidazoles XIII. Synthesis of Substituted (1-Methyl-5-Nitro-2-Imidazolyl) Isoxazoles [PDF]
The beta0diketone derivatives of nitroimidazole were synthesized from the reaction of magnesium salt of beta-ketoaccids 3 with imidazolide 4. The raction of beta-diketones with hydroxylamine hydrochloride afforded either the isoxazoles or the 5-hydroxyl ...

Synthesis of stable isoxazolines by [3+2] cycloaddition of oxaziridines with alkynes.
N-Alkyl substituted oxaziridines undergo a [3+2] cycloaddition reaction with a variety of terminal alkynes to give the product isoxazolines, whose stability appears to depend on the electronic properties of the groups on the C-3 and C-5 positions.

We have developed a Pd‐catalyzed oxidative cyclopropanation of 1,n‐enynes employing cyclic diacyl peroxides as bifunctional reagents that serve as both tether‐tunable oxidants and spatially controlled dicarboxylate anions. ABSTRACT Bicyclo[n.1.0]alkanes are highly valuable scaffolds in drug discovery and synthetic chemistry.
