Structure−Affinity Relationships of a Unique Nicotinic Ligand: N-Dimethyl-N4-phenylpiperazinium Iodide (DMPP)
摘要:
DMPP is a well-known nicotinic agonist that does not fit any proposed pharmacophore for nicotinic binding and represents a unique ligand among the hundreds of nicotinic agonists studied in the past decades. A systematic modulation of the chemical structure of DMPP, aimed to establish its structure-affinity relationships, is reported. The research has allowed to identify molecules such as I Ic, 13c, 14c, and 28c, with affinities for alpha (4)beta (2) receptors in the low nanomolar range, some 2 orders of magnitude lower than the lead compound. The agonistic properties of the most interesting compounds have been assessed by measuring their analgesic activity on mice (hot-plate test). Another result of the research was the identification of DMPP analogues, such as 3a (K-i = 90 nM) and 14b (K-i = 180 nM), that maintain affinity for the central nicotinic receptor when the ammonium function is changed into an aminic one and are therefore possible leads for drug development in neurodegenerative diseases.

general and effective CuI/N′,N′-diaryl-1H-pyrrole-2-carbohydrazide catalyst system was developed for the amination of aryliodides and bromides at room temperature with good chemoselectivity between −OH and −NH2 groups. Only 5 mol % of CuI and ligands was needed in this protocol to effect the amination of various arylbromides and aryliodides with a wide range of aliphatic and aryl amines (1.3 equiv)

intermediates is not necessary, allowing the synthesis of pyridine-2,6-diamines in ‘one-pot’. However, catalysts are in many cases not required to efficiently and selectively couple aryl halides with amines, making transition metal-free versions of the Buchwald–Hartwig reaction extremely attractive for the synthesis of N-arylated amines with substrates containing substituents on the aryl halide, which either promote
