Macrolide Inspired Macrocycles as Modulators of the IL-17A/IL-17RA Interaction.

Interleukin 17 (IL-17) cytokines promote inflammatory pathophysiology in many autoimmune diseases, including psoriasis, multiple sclerosis, rheumatoid arthritis, and inflammatory bowel disease. Such broad involvement of IL-17 in various autoimmune diseases makes it an ideal target for drug discovery. Psoriasis is a chronic inflammatory disease characterized by numerous defective components of the immune system.

Competition between fluorescence and triplet production ruled by nitro groups in one-arm and two-arm styrylbenzene heteroanalogues.

The competition between excited state deactivation processes in mono and double-arm push-pull systems bearing pyridine, furan or thiophene (electron donors) and nitro groups (electron acceptors) was investigated in several solvents through nanosecond and femtosecond transient absorption spectroscopy. Triplet population is the main deactivation pathway for the mono-arm compounds. The large triplet production is mainly ascribed to (n,π*) states almost isoenergetic to S, introduced by nitro groups, as predicted by TD-DFT calculations.

Benzobicyclo[3.2.1]octene Derivatives as a New Class of Cholinesterase Inhibitors.

A library of amine, oxime, ether, epoxy and acyl derivatives of the benzobicyclo[3.2.1]octene were synthesized and evaluated as inhibitors of both human acetylcholinesterase (AChE) and butyrylcholinesterase (BChE).

Design, synthesis and cholinesterase inhibitory properties of new oxazole benzylamine derivatives.

The enzymes acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) are primary targets in attenuating the symptoms of neurodegenerative diseases. Their inhibition results in elevated concentrations of the neurotransmitter acetylcholine which supports communication among nerve cells. It was previously shown for 4/5-arylethenyloxazole compounds to have moderate AChE and BChE inhibitory properties.
