The role of the L-arginine-NO-cGMP-dependent pathway in the development of sensitization to mephedrone effects on the locomotor activity in mice. Behav Brain Res 2023; 437:114103. [PMID: 36089098 DOI: 10.1016/j.bbr.2022.114103] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2021] [Revised: 09/04/2022] [Accepted: 09/05/2022] [Indexed: 10/14/2022]
Abstract
Mephedrone, a popular psychostimulating substance widely used illegally in recreational purposes, exerts in rodents that regularly and intermittently were exposed to it a sensitized response to the drug. Behavioral sensitization is one of experimental models of drug dependency/abuse liability. In the present study we evaluated a potential involvement of the L-arginine-NO-cGMP pathway in the development of sensitization to the mephedrone-induced hyperlocomotion. Locomotor activity was measured automatically and experiments were performed on male Albino Swiss mice. We demonstrated that a 5-day administration of 7-nitroindazole (10 or 20 mg/kg/day) and L-NAME (50 mg/kg/day) suppressed the development of sensitization to the mephedrone-induced hyperlocomotion. As for L-arginine (125 or 250 mg/kg/day) and methylene blue (5 or 10 mg/kg/day) the obtained outcomes are inconclusive. Furthermore, the lower dose of L-NAME (25 mg/kg/day) surprisingly potentiated the development of sensitization to the mephedrone-induced effects on the spontaneous locomotor activity in mice. In conclusion, our data demonstrated that modulators of the L-arginine-NO-cGMP pathway may differently affect the development of sensitization to the locomotor stimulant effects of mephedrone. Inhibition of neuronal nitric oxide synthase (NOS) seems to prevent this process quite profoundly, non-selective inhibition of NOS may have a dual effect, whereas inhibition of soluble guanylate cyclase may only partially suppress the development of sensitization to the mephedrone-induced effects.

Bioact Mater 2022; 13:223-238. [PMID: 35224304 PMCID: PMC8843980 DOI: 10.1016/j.bioactmat.2021.10.048] [Citation(s) in RCA: 18] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2021] [Revised: 10/19/2021] [Accepted: 10/30/2021] [Indexed: 12/13/2022] Open
Abstract
The presence of multiple immunosuppressive targets and insufficient activation and infiltration of cytotoxic T lymphocytes (CTLs) allow tumor cells to escape immune surveillance and disable anti-PD-1/PD-L1 immunotherapy. Nanobiotechnology-engineered autologous tumor vaccines (ATVs) that were camouflaged by tumor cell membrane (TCM) were designed to activate and facilitate CTLs infiltration for killing the unprotected lung tumor cells, consequently realizing the sequential immunotherapy. PDE5 was firstly screened out as a new immunosuppressive target of lung cancer in clinical practice. Immediately afterwards, phosphodiesterase-5 (PDE5) and programmed cell death 1 ligand 1 (PD-L1) dual-target co-inhibition was proposed to unfreeze the immunosuppressive microenvironment of NSCLC. Systematic studies validated that this ATVs-unlocked sequential immunotherapy after co-encapsulating PDE5 inhibitor and NO donor (i.e., l-arginine) exerted robust anti-tumor effects through increasing inducible nitric oxide synthase (iNOS) expression, blockading PDE5 pathway and activating systematic immune responses, which synergistically eradicated local and abscopal lung cancers in either orthotopic or subcutaneous models. The pluripotent ATVs that enable PDE5 inhibition and sequential immunotherapy provide a new avenue to mitigate immunosuppressive microenvironment and magnify anti-PD-1/PD-L1 immunotherapy. A clinically-screened NSCLC immunosuppressive target (PDE5) is experimentally validated available for designing new drugs. Pluripotent ATVs unlock sequential immunotherapy via PDE5&PD-L1 co-inhibition and TCM antigens-arised immune activation. NO donor loaded in ATVs augmented PDE5i efficacy and magnified sequential immunotherapy along with TCM-enabled tumor tropism.

Curr Drug Targets 2021; 22:539-554. [PMID: 32881667 DOI: 10.2174/1389450121666200902171838] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2020] [Revised: 05/09/2020] [Accepted: 05/18/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Natural products, such as phenylpropanoids, which are found in essential oils derived from aromatic plants, have been explored during non-clinical psychopharmacology studies, to discover new molecules with relevant pharmacological activities in the central nervous system, especially antidepressant and anxiolytic activities. Major depressive disorder is a highly debilitating psychiatric disorder and is considered to be a disabling public health problem, worldwide, as a primary factor associated with suicide. Current clinically administered antidepressants have late-onset therapeutic actions, are associated with several side effects, and clinical studies have reported that some patients do not respond well to treatment or reach complete remission. OBJECTIVE To review important new targets for antidepressant activity and to select phenylpropanoids with antidepressant activity, using Molegro Virtual Docker and Ossis Data Warris, and to verify substances with more promising antidepressant activity. RESULTS AND CONCLUSION An in silico molecular modeling study, based on homology, was conducted to determine the three-dimensional structure of the 5-hydroxytryptamine 2A receptor (5- HT2AR), then molecular docking studies were performed and the predisposition for cytotoxicity risk among identified molecules was examined. A model for 5-HT2AR homology, with satisfactory results, was obtained indicating the good stereochemical quality of the model. The phenylpropanoid 4-allyl-2,6-dimethoxyphenol showed the lowest binding energy for 5-HT2AR, with results relevant to the L-arginine/nitric oxide (NO)/cGMP pathway, and showed no toxicity within the parameters of mutagenicity, carcinogenicity, reproductive system toxicity, and skin-tissue irritability, when evaluated in silico; therefore, this molecule can be considered promising for the investigation of antidepressant activity.
