Design, synthesis, and biological evaluation of pirenzepine analogs bearing a 1,2-cyclohexanediamine and perhydroquinoxaline units in exchange for the piperazine ring as antimuscarinics
摘要:
Pirenzepine (2) is one of the most selective muscarinic M-1 versus M-2 receptor antagonists known. A series of 2 analogs, in which the piperazyl moiety was replaced by a cis-and trans-cyclohexane-1,2-diamine (3-6) or a trans-and cis-perhydroquinoxaline rings (7 and 8) were prepared, with the aim to investigate the role of the piperazine ring of 2 in the interaction with the muscarinic receptors. The structural change leading to compounds 3-6 abolished in binding assays the muscarinic M-1/M-2 selectivity of 2, due to an increased M-2 affinity. Rather, compounds 3-6 displayed a reversed selectivity showing more affinity at the muscarinic M-2 receptor than at all the other subtypes tested. (C) 2008 Elsevier Ltd. All rights reserved.
The conventional anticholinergic drugs for administration through inhalation have been considered to have the possibility of aggravating dysuria associated with prostatic hyperplasia mediated by blood, and it has been demanded that the conventional anticholinergic drugs for administration through inhalation will have to show reduced side effects or adverse ractions.
The present invention relates to a compound represented by the general formula (I):
(wherein A represents;
and R1, R2, R3 and R1 each a hydrogen atom or a substituent;
R5 is a substituent; X- is an anion;the symbol:
denotes an exo-form or endo-form, or their mixture), its salt or solvation product thereof. They are useful as a prophylactic and/or therapeutic agent with reduced side effects or adverse reactions for the diseases mediated by the muscarinic receptor.
The present invention relates to perhydroquinoxaline derivatives, processes for their preparation, their use for the preparation of a medicament and medicaments containing perhydroquinoxaline derivatives.
