Here we report the design, synthesis, and 5-HT(7) receptor affinity of a set of 1-(3-biphenyl)- and 1-(2-biphenyl)piperazines. The effect on 5-HT(7) affinity of various substituents on the second (distal) phenyl ring was analyzed. Several compounds showed 5-HT(7) affinities in the

Carboxyls are inherent functional groups of thin-film composite polyamide nanofiltration (NF) membranes, which may play a role in membrane performance and fouling. Their surface presence is attributed to incomplete reaction of acyl chloride monomers during the membrane active layer synthesis

New tacrine derivatives 5a-d, 6a-d with piperazino-ethyl spacer linked with corresponding secondary amines and tacrine homodimer 8 were synthesized and tested as cholinesterase inhibitors on human acetylcholinesterase (hAChE) and human plasmatic butyrylcholinesterase (hBChE). In most cases the majority of synthesized
