PD 102807, a novel muscarinic M4 receptor antagonist, discriminates between striatal and cortical muscarinic receptors coupled to cyclic AMP.[Pubmed:10576595]
Life Sci. 1999;65(21):2233-40.
In membranes of Chinese hamster ovary cells expressing the cloned human M1-M4 muscarinic receptor subtypes, PD 102807, a novel M4 selective antagonist, was found to counteract the M4 receptor-induced stimulation of [35S]-GTPgammaS binding to membrane G proteins with a pK(B) of 7.40, a value which was 63-, 33- and 10-fold higher than those displayed at M1 (pK(B) = 5.60), M2 (pK(B) = 5.88) and M3 (pK(B) = 6.39) receptor subtypes, respectively. In rat striatal membranes, PD 102807 antagonized the muscarinic inhibition of dopamine (DA) D1 receptor-stimulated adenylyl cyclase with a pK(B) value of 7.36. In contrast, in membranes of rat frontal cortex, PD 102807 displayed lower potencies in antagonizing either the muscarinic facilitation of corticotropin releasing hormone (CRH)-stimulated adenylyl cyclase (pK(B) = 5.79) or inhibition of Ca2+/calmodulin (Ca2+/CaM)-stimulated enzyme activity (pK(B) = 5.95). In each response investigated, PD 102807 interacted with muscarinic receptors in a manner typical of a simple competitive antagonist. These data provide additional evidence that PD 102807 is a M4-receptor preferring antagonist and that this compound can discriminate the striatal muscarinic receptors inhibiting DA D1 receptor activity from the cortical receptors mediating the potentiation of CRH receptor signalling and the inhibition of Ca2+/CaM-stimulated adenylyl cyclase activity.
Synthesis and pharmacology of benzoxazines as highly selective antagonists at M(4) muscarinic receptors.[Pubmed:12086495]
J Med Chem. 2002 Jul 4;45(14):3094-102.
Previously, we reported on PD 102807 (41) as being the most selective synthetic M(4) muscarinic antagonist identified to date. Synthesized analogues of 41 showed no improvement in affinity and selectivity at that time. However, several newly synthesized compounds exhibit a 7-fold higher affinity at M(4) receptors and demonstrate a selectivity of at least 100-fold over all other muscarinic receptor subtypes. For example, compound 28 showed an affinity of pK(i) = 9.00 at M(4) receptors and a selectivity of M(1)/M(4) = 13 183-fold, M(2)/M(4) = 339-fold, M(3)/M(4) = 151-fold, and M(5)/M(4) = 11 220-fold. This high selectivity along with high affinity has not been reported for any synthetic muscarinic antagonist, nor for natural occurring M(4) antagonists such as the M(4) selective Eastern Green Mamba venom MT3 (M(4) pK(b) = 8.7, M(1)/M(4) = 40-fold, M(2)/M(4) > or = 500-fold, M(3)/M(4) > or = 500-fold, and M(5)/M(4) > or = 500-fold). Derivative 24, a compound with a high selectivity pattern as well, has been tested for in vivo efficacy. It was able to block the L-3,4-dihydroxyphenylalanine accumulation produced by CI-1017, an M(1)/M(4) selective muscarinic agonist, in the mesolimbic region and striatum, which suggests that 24 is capable of crossing the blood-brain barrier and confirms the pharmacokinetic data obtained on this compound. This is evidence that suggests that agonist-induced increase in catecholamine synthesis observed in these regions is mediated by M(4) receptors.
A novel muscarinic M(4) receptor antagonist provides further evidence of an autoreceptor role for the muscarinic M(2) receptor sub-type.[Pubmed:10556681]
Eur J Pharmacol. 1999 Oct 21;383(1):53-6.
Muscarinic M(2) (AF-DX 384, BIBN-161) and M(4) (PD102807) receptor antagonists were used to investigate the respective roles of these two receptor sub-types in the regulation of acetylcholine release in the rat hippocampus. In vivo dialysis studies revealed that only the muscarinic M(2) receptor antagonists significantly and concentration-dependently facilitate acetylcholine release. The newly developed muscarinic M(4) receptor antagonist was unable to regulate acetylcholine release except at the highest concentration tested. It would thus appear that the muscarinic receptor acting as negative autoreceptor in the rat hippocampus is of the muscarinic M(2) sub-type, the role of the muscarinic M(4) receptor being minimal in this regard.
Identification and characterization of m4 selective muscarinic antagonists.[Pubmed:9873472]
Bioorg Med Chem Lett. 1998 Aug 4;8(15):1991-6.
Our interest in the area of m4 muscarinic antagonists had led us to study a series of benzoxazine isoquinolines. One of the most potent and selective compounds of this series is example 1 with an IC50 value of 90.7 nM at m4 receptors, and 72-fold (m1), 38-fold (m2), 10-fold (m3), and 82-fold (m5) more selective compared to the other receptors. The synthesis and receptor binding affinity of analogs of 1 are reported.
