Molecules 2018; 23:E1611. [PMID: 30004445 PMCID: PMC6099947 DOI: 10.3390/molecules23071611] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2018] [Revised: 06/29/2018] [Accepted: 06/30/2018] [Indexed: 02/07/2023] Open
Abstract
This review focuses on the biological action of the compounds from the group of substituted 1,3,4-thiadiazines on stress response and myocardial infarction. The aim of this review is to propose the possible mechanisms of action of 1,3,4-thiadiazines and offer prospectives in the development of new derivatives as therapeutic agents. It is known, that compounds that have biological effects similar to those used as antidepressants can down-regulate the secretion of proinflammatory cytokines, up-regulate the release of anti-inflammatory ones and affect cell recruitment, which allows them to be considered immunomodulators as well. The results of pharmacological evaluation, in silico studies, and in vivo experiments of several compounds from the group of substituted 1,3,4-thiadiazines with antidepressant properties are presented. It is proposed that the cardioprotective effects of substituted 1,3,4-thiadiazines might be explained by the peculiarities of their multi-target action: the ability of the compounds to interact with various types of receptors and transporters of dopaminergic, serotonergic and acetylcholinergic systems and to block the kinase signal pathway PI3K-AKT. The described effects of substituted 1,3,4-thiadiazines suggest that it is necessary to search for a new agents for limiting the peripheral inflammatory/ischemic damage through the entral mechanisms of stress reaction and modifying pro-inflammatory cytokine signaling pathways in the brain.

Sexually diergic hypothalamic-pituitary-adrenal axis responses to selective and non-selective muscarinic antagonists prior to cholinergic stimulation by physostigmine in rats. Brain Res Bull 2017; 137:23-34. [PMID: 29122691 DOI: 10.1016/j.brainresbull.2017.11.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2017] [Revised: 10/21/2017] [Accepted: 11/02/2017] [Indexed: 01/02/2023]
Abstract
Central cholinergic systems regulate the hypothalamic-pituitary-adrenal (HPA) axis differentially in males and females (sexual diergism). We previously investigated the role of muscarinic receptors in this regulation by administering physostigmine (PHYSO), an acetylcholinesterase inhibitor, to male and female rats pretreated with scopolamine (SCOP), a nonselective muscarinic antagonist. SCOP pretreatment enhanced adrenocorticotropic hormone (ACTH) and corticosterone (CORT) responses in both sexes, but males had greater ACTH responses while females had greater CORT responses. In the present study, we further explored the role of muscarinic receptor subtypes in HPA axis regulation by administering PHYSO to male and female rats following SCOP or various doses of either the M1 or the M2 selective muscarinic receptor antagonists, pirenzepine (PIREN) or methoctramine (METHO). Blood was sampled before and at multiple times after PHYSO. ACTH and CORT were determined by highly specific immunoassays. M1 antagonism by PIREN prior to PHYSO resulted in sustained, dose-dependent increases in ACTH and CORT: ACTH responses were similar in both sexes, and CORT responses were greater in females. M2 antagonism by METHO prior to PHYSO resulted in overall decreases in ACTH and CORT: ACTH and CORT responses were higher in females but lower in both sexes than the hormone responses following PIREN or SCOP pretreatment. Area under the curve analyses supported these findings. These results suggest that specific muscarinic receptor subtypes differentially influence the HPA axis in a sexually diergic manner.

Abstract
Because the five muscarinic acetylcholine receptor subtypes have overlapping distributions in many CNS tissues, and because ligands with a high degree of selectivity for a given subtype long remained elusive, it has been difficult to determine the physiological functions of each receptor. Genetically engineered knockout mice, in which one or more muscarinic acetylcholine receptor subtype has been inactivated, have been instrumental in identifying muscarinic receptor functions in the CNS, at the neuronal, circuit, and behavioral level. These studies revealed important functions of muscarinic receptors modulating neuronal activity and neurotransmitter release in many brain regions, shaping neuronal plasticity, and affecting functions ranging from motor and sensory function to cognitive processes. As gene targeting technology evolves including the use of conditional, cell type specific strains, knockout mice are likely to continue to provide valuable insights into brain physiology and pathophysiology, and advance the development of new medications for a range of conditions such as Alzheimer's disease, Parkinson's disease, schizophrenia, and addictions, as well as non-opioid analgesics. This article is part of the Special Issue entitled 'Neuropharmacology on Muscarinic Receptors'.

Int Immunopharmacol 2015; 29:135-42.

Abstract
The existence of interactions between the immune and the sympathetic nervous systems is well established. Noradrenaline can promote or inhibit the immune response, and conversely, the immune response itself can affect noradrenaline concentration in lymphoid organs, such as the spleen. It is also well known that acetylcholine released by pre-ganglionic neurons can modulate noradrenaline release by the postsynaptic neuron. The spleen does not receive cholinergic innervation, but it has been reported that lymphocytes themselves can produce acetylcholine, and express acetylcholine receptors and acetylcholinesterase. We found that the spleen of not overtly immunized mice in which muscarinic type 1 acetylcholine receptors have been knocked out (M1KO) has higher noradrenaline concentrations than that of the wildtype mice, without comparable alterations in the heart, in parallel to a decreased number of IgG-producing B cells. Splenic lymphocytes from M1KO mice displayed increased in vitro-induced cytotoxicity, and this was observed only when CD4(+) T cells were present. In contrast, heterozygous acetylcholinesterase (AChE+/-) mice, had no alterations in splenic noradrenaline concentration, but the in vitro proliferation of AChE+/- CD4(+) T cells was increased. It is theoretically conceivable that reciprocal effects between neuronally and non-neuronally derived acetylcholine and noradrenaline might contribute to the results reported. Our results emphasize the need to consider the balance between the effects of these mediators for the final immunoregulatory outcome.

Silveira MM, Malcolm E, Shoaib M, Winstanley CA. Scopolamine and amphetamine produce similar decision-making deficits on a rat gambling task via independent pathways. Behav Brain Res 2014; 281:86-95. [PMID: 25529186 DOI: 10.1016/j.bbr.2014.12.029] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2014] [Revised: 12/09/2014] [Accepted: 12/11/2014] [Indexed: 01/12/2023]
Abstract
Disorders characterized by disturbed cholinergic signaling, such as schizophrenia, exhibit impaired performance on measures of real-world cost/benefit decision-making. Whether the cholinergic system contributes to the choice deficits observed is currently unknown. We therefore determined the effects of broad-acting agonists and antagonists at the nicotinic and muscarinic receptor on decision making, as measured by the rodent gambling task (rGT). Given the anatomical and functional connectivity of the cholinergic and dopaminergic systems, we also sought to modulate amphetamine's previously reported effect on rGT performance via the cholinergic system. Male rats were trained on the rGT, during which animals chose from four different options. The optimal strategy on the rGT is to favor options associated with smaller immediate rewards and less punishment/loss. Impulsive action was also measured by recording the number of premature responses made. Performance on the rGT was assessed following acute treatment with the muscarinic receptor agonist oxotremorine, the muscarinic receptor antagonist scopolamine, nicotine, and the nicotinic receptor antagonist mecamylamine. Similar to the effect produced by amphetamine, muscarinic receptor antagonism with scopolamine (0.1mg/kg) impaired decision making, albeit to a lesser degree. Prior muscarinic agonism with oxotremorine was unable to attenuate amphetamine's effects on rGT performance. Oxotremorine, nicotine, and mecamylamine did not affect the choice profile. We therefore conclude that modulation of the muscarinic, but not nicotinic, receptor system can affect decision making under conditions of risk and uncertainty. Such findings contribute to a broader understanding of the cognitive deficits observed in disorders in which cholinergic signaling is compromised.

Abstract
Although c-Fos plays a key role in intracellular signalling, the disruption of the c-fos gene has only minor consequences on the central nervous system (CNS) function. As muscarinic receptors (MR) play important roles in many CNS functions (attention, arousal, and cognition), the c-fos knock-out might be compensated through MR changes. The aim of this study was to evaluate changes in the M1-M5 MR mRNA in selected CNS areas: frontal, parietal, temporal and occipital cortex, striatum, hippocampus, hypothalamus and cerebellum (FC, PC, TC, OC, stria, hip, hypo, and crbl, respectively). Knocking out the c-fos gene changed the expression of MR in FC (reduced M1R, M4R and M5R expression), TC (increased M4R expression), OC (decreased M2R and M3R expression) and hippocampus (reduced M3R expression). Moreover, gender differences were observed in WT mice: increased expression of all M1-M5R in the FC in males and M1-M4R in the striatum in females. A detailed analysis of MR transcripts showed pre-existing correlations in the amount of MR-mRNA between specific regions. WT mice showed three major types of cortico-cortical correlations: fronto-occipital, temporo-parietal and parieto-occipital. The cortico-subcortical correlations involved associations between the FC, PC, TC and striatum. In KO mice, a substantial rearrangement of the correlation pattern was observed: only a temporo-parietal correlation and correlations between the FC and striatum remained, and a new correlation between the hypothalamus and cerebellum appeared. Thus, in addition to the previously described dopamine receptor restructuring, the restructuring of MR mRNA correlations reveals an additional mechanism for adaptation to the c-fos gene knockout.

Sexually diergic hypothalamic-pituitary-adrenal (HPA) responses to single-dose nicotine, continuous nicotine infusion, and nicotine withdrawal by mecamylamine in rats. Brain Res Bull 2011; 85:145-52. [PMID: 21396990 DOI: 10.1016/j.brainresbull.2011.03.001] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2010] [Revised: 03/02/2011] [Accepted: 03/03/2011] [Indexed: 10/18/2022]
Abstract
Hypothalamic-pituitary-adrenal (HPA) responses to single-dose nicotine (NIC) are sexually diergic: Female rats have higher adrenocorticotropic hormone (ACTH) and corticosterone (CORT) responses than do males. In the present study we determined HPA responses in male and female rats following single doses of NIC, a single-dose of NIC immediately following continuous NIC for two weeks, and NIC withdrawal by single-dose mecamylamine (MEC) following continuous NIC infusion for two weeks. Blood sampling occurred before and after MEC and NIC administrations for the determination of ACTH and CORT. In accordance with our previous findings, female ACTH and CORT responses to single-dose NIC were greater than male responses. This sex difference remained after single-dose NIC followed continuous NIC infusion, but HPA responses in both sexes were significantly lower in magnitude and duration than in the single-dose NIC alone groups. Sex differences also were observed following NIC withdrawal by MEC: the HPA responses to pretreatment with MEC were significantly higher in magnitude and duration in the continuous NIC groups than in the single-dose NIC groups. These results demonstrate that HPA responses to NIC are reduced and transient following continuous NIC infusion but are enhanced and sustained following NIC withdrawal by MEC after continuous NIC, suggesting that NIC habituation and withdrawal influence the stress responses in a diergic manner. These findings highlight the importance of sex differences in the effect of NIC on HPA axis activity and stress responsiveness, which may have implications for directing NIC-addiction treatment specifically towards men and women.

Modulation of prepulse inhibition through both M(1) and M (4) muscarinic receptors in mice. Psychopharmacology (Berl) 2010; 208:401-16. [PMID: 20013114 PMCID: PMC3895331 DOI: 10.1007/s00213-009-1740-z] [Citation(s) in RCA: 34] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2009] [Accepted: 11/17/2009] [Indexed: 12/11/2022]
Abstract
RATIONALE Muscarinic cholinergic M(1) and M(4) receptors may participate in schizophrenia's etiology and have been proposed as targets for antipsychotic medications. OBJECTIVE Here, we investigated the involvement of these receptors in behavioral measures pertinent to schizophrenia using knockout mice lacking M(1) receptors (M(1)-/-), M(4) receptors (M(4)-/-), or both (M(1)-/-M(4)-/-). METHODS We measured prepulse inhibition (PPI) of startle without drugs and after treatment with scopolamine (0.32-1.8 mg/kg), xanomeline (3.2 mg/kg), oxotremorine (0.032-0.1 mg/kg), clozapine (1.0-5.6 mg/kg), or haloperidol (0.32-3.2 mg/kg). RESULTS In female (but not male) mice, combined deletion of both M(1) and M(4) receptors decreased PPI relative to wild-type mice, while knockout of either receptor alone had no significant effect. Scopolamine disrupted PPI in wild-type and M(4)-/- mice, but not in female M(1)-/-M(4)-/- or female M(1)-/- mice. When administered before scopolamine, xanomeline restored PPI in wild-type mice and M(1)-/- mice, but not in M(4)-/- mice. In contrast, pretreatment with oxotremorine increased PPI regardless of genotype. Effects of clozapine and haloperidol on PPI were not hindered by either mutation. CONCLUSIONS Deletion of both M(1) and M(4) receptors can disrupt PPI, suggesting that (at least partially redundant) M(1) and M(4) receptor-dependent functions are involved in sensorimotor gating mechanisms. PPI-disrupting effects of muscarinic antagonists appeared dependent upon M(1) receptor blockade. Our data also suggest that xanomeline exerts antipsychotic-like effects mainly through M(4) receptor stimulation, while stimulation of non-M(1)/M(4) subtypes may also have antipsychotic potential. Finally, our results do not support a role of M(1)/M(4) receptors in mediating antipsychotic-like effects of clozapine.
