These stabilised molecular patterns represent an ideal template for information storage in the human brain because of the large number of asymmetric centres present in sugar molecules with attached hydroxyl groups. Hydrogen bonding of hydroxyl groups present on sugar molecules with other hydroxyl or amino groups on nearby sugar or nucleic acid units, through intramolecular or intermolecular hydrogen bonding, can result in the formation of memory patterns comprising such \"frozen conformers\". This mechanism can be involved in learning, information storage, and its recall. Penrose and Hameroff's orchestrated objective reduction (Orch OR) theory proposes that quantum superpositions and entanglement within neuronal microtubules are orchestrated by cellular processes and periodically undergo objective reduction, yielding discrete moments of conscious awareness. Recent developments in quantum biology and protein photophysics have significantly narrowed the gap between these perspectives. Most notably, Babcock et al. (2024) demonstrated that ultraviolet super radiance can occur in tryptophan- containing protein networks, including tubulin assemblies, indicating that protein architectures can support collective excitonic states (and associated subradiant \"dark\" manifolds) under physiological conditions. These findings can potentially address decoherence objections and provide a tangible mechanism by which aromatic amino-acid networks could mediate coherent energy/information transfer in living cells. We present here a possible unified model combining these concepts: Microtubules are proposed to function as quantum information processors that may bind and route distributed information through excitonic or entanglement dynamics, while glycoprotein conformational patterns could serve as a molecular register for memory storage. The convergent evidence from spectroscopy, anesthetic pharmacology, and glycosylation biology are reviewed in this context. The combination of these concepts can offer a mechanistic bridge between quantum events and cognitive function.</p>","PeriodicalId":10984,"journal":{"name":"Current medicinal chemistry","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145148050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A comprehensive search of PubMed, Scopus, Embase, PsycINFO, and Google Scholar databases was conducted for studies published between March 1, 2007, and December 30, 2024. The search utilized keywords related to NAC and psychiatric disorders. Data were critically analyzed to evaluate NAC's therapeutic potential. Preclinical studies demonstrate NAC's benefits in reducing oxidative stress, inflammation, and modulating neurotransmitter systems. Animal models of depression, schizophrenia, and OCD show symptom reduction through glutamatergic and antioxidant mechanisms. Clinical trials reveal NAC's efficacy as an adjunct in treating major depressive disorder, bipolar disorder, and schizophrenia, particularly for negative and cognitive symptoms. Evidence for anxiety disorders, PTSD, and OCD is limited but suggests anxiolytic and anti-obsessive effects. In SUDs, NAC shows promise in reducing cravings and substance- seeking behavior, while preliminary findings in autism suggest improvements in irritability and hyperactivity. NAC exhibits potential as an adjunctive treatment for various psychiatric disorders due to its safety profile, low cost, and broad mechanisms of action.

Antibody-drug conjugates (ADCs) have been established as a potential strategy for selectively targeting and eradicating CSCs, thereby overcoming resistance mechanisms and preventing tumor recurrence. ADCs integrate a monoclonal antibody specific to CSC surface markers, such as CD44, CD133, EpCAM, and ALDH1, with a potent cytotoxic payload linked by a stable chemical linker. Upon antigen binding, ADCs undergo receptor-mediated internalization, leading to intracellular payload release and CSC apoptosis. Recent advances in ADC technology have enhanced selectivity and efficacy while minimizing off-target toxicity. Preclinical studies demonstrate that CSC-targeted ADCs, including CD133- and CD44-directed therapies, effectively deplete CSC populations in glioblastoma, breast, colorectal, and lung cancers. EpCAM-targeted ADCs have also shown efficacy in epithelial tumors with potential synergy in combination immunotherapies. Moreover, emerging approaches, such as bispecific antibodies and optimized linker chemistry, further refine CSC-targeted ADCs for clinical applications. Despite these advancements, challenges remain, including CSC heterogeneity, immune evasion, and limitations in biomarker specificity. Addressing these hurdles requires continued innovation in ADC engineering, novel payloads, and combinatory strategies with immune checkpoint inhibitors or CAR-T cell therapies. While clinical evaluations are still in the early phases, preliminary trials underscore the potential of CSC-targeted ADCs in revolutionizing precision oncology.
