Discovery and Pharmacological Profile of New 1H-Indazole-3-carboxamide and 2H-Pyrrolo[3,4-c]quinoline Derivatives as Selective Serotonin 4 Receptor Ligands
摘要:
Since the discovery of the serotonin 4 receptor (5-HT4R), a large number of receptor ligands have been studied. The safety concerns and the lack of market success of these ligands have mainly been attributed to their lack of selectivity. In this study we describe the discovery of N-[(4- piperidinyl)methyl]-1H-indazole-3-carboxamide and 4-[(4-piperidinyl)methoxy]-2H-pyrrolo[3,4-c]quinoline derivatives as new 5-HT4R ligands endowed with high selectivity over the serotonin 2A receptor and human ether-a-go-go-related gene potassium ion channel. Within these series, two molecules (11ab and 12g) were identified as potent and selective 5-HT4R antagonists with good in vitro pharmacokinetic properties. These compounds were evaluated for their antinociceptive action in two analgesia animal models. 12g showed a significant antinociceptive effect in both models and is proposed as an interesting lead compound as a 5-HT4R antagonist with analgesic action.

The present invention relates to provided spirocyclopropylamine compounds, endowed with a potent KDM1A (LSD1) inhibitory activity, wherein X, R, and R1 are as defined in the specification, pharmaceutical compositions containing such compounds and to their use in therapy.
designed as human A2A AR antagonists/inverseagonists. Binding and potency data indicated that a good number of potent and selective hA2A AR inverseagonists were found. Amongst them, the 2-(furan-2-yl)-N5-(2-(4-phenylpiperazin-1-yl)ethyl)thiazolo[5,4-d]pyrimidine-5,7-diamine 11 exhibited the highest A2A AR binding affinity (Ki = 8.62 nM) as well as inverseagonist potency (IC50 = 7.42 nM). In addition

Compounds of general formula I (Z=O) are prepared by reacting 4-piperidinealkanamines with carboxylic acids or reactive derivatives thereof, such as the esters of lower aliphatic alcohols or acid halides. Compounds of general formula I (Z=CONH) are likewise obtained by means of the reaction between 4-piperidinealcanamines and isocyanates.
The compounds of general formula I thus obtained, and the pharmaceutically acceptable salts thereof are of a great therapeutic utility, given their activity as specific antagonists of histamine H₁ receptors.
