Amini MJ, Seighali N, Arabazadeh Bahri R, Ala M, Mohammad Jafari R, Dehpour AR. Repurposing of modafinil as an anti-inflammatory drug: a systematic review of experimental studies. NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2025:10.1007/s00210-025-03964-9. [PMID: 40358683 DOI: 10.1007/s00210-025-03964-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/27/2024] [Accepted: 02/19/2025] [Indexed: 05/15/2025]
Abstract
Previous studies suggested the anti-inflammatory properties of modafinil. This study aimed to review the current literature to provide a comprehensive insight into the anti-inflammatory uses of modafinil in experimental studies. We conducted a systematic search using Medline (via PubMed), Web of Science, Scopus, and Embase databases from their commencement until 10 October 2022. All original articles focusing on modafinil anti-inflammatory effects were included. Our initial search yielded 1398 articles. Fourteen publications were included in our systematic review. Recent studies attempted to provide evidence for repurposing modafinil for several diseases, including autoimmune encephalomyelitis, nonalcoholic liver disease, gastric mucosal injury, neuropathic pain, atherosclerosis, intestinal ischemia, pulmonary hypertension, pancreatitis, ischemic stroke, testicular torsion, and lithium-pilocarpine-induced status epilepticus. Current evidence supports that modafinil can modulate inflammation, suppress the immune response, and improve disease severity partly by inhibiting NF-κB, NOS, Kca3.1, Kca2.3, and COX-2. By reviewing recent findings from experimental studies, we discussed the beneficial effects of modafinil on several inflammatory diseases, with a particular focus on the underlying mechanisms.

Sugaya M, Nagashima A, Nakamura R, Yano M, Morita T, Niijima Y, Takekoshi T, Kanda N, Tanaka M. Treatment of facial reactive B-cell rich lymphoid proliferation with dapsone. J Dermatol 2025; 52:735-739. [PMID: 39803744 DOI: 10.1111/1346-8138.17614] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2024] [Revised: 12/19/2024] [Accepted: 12/20/2024] [Indexed: 04/08/2025]
Abstract
Reactive B-cell rich lymphoid proliferation (rB-LP), once called pseudolymphoma, is a benign lymphoproliferative disorder, which is histologically characterized by dense dermal infiltrate forming reactive germinal centers with tingible body macrophages. The disease frequently involves the face, scalp, and ear lobes. Treatment includes topical or intralesional steroids, surgical resection, ultraviolet therapy, laser treatment, and radiation therapy. Cases with multiple skin lesions, however, are difficult to treat with local therapies. Oral steroids are sometimes used, although the variety of side effects and recurrence during decreases in the dosage are the main problem. Here we report seven cases of rB-LP treated with dapsone, which has anti-inflammatory effect. Although the number of cases was limited, there was a trend that patients with multiple nodules on both sides of the face showed a good response. The limitations of this study include it being a case series from a single institute, and possible effects of topical steroids. We can, however, safely say that dapsone may be useful in some patients with rB-LP.

Pharmacol Rep 2025; 77:315-332. [PMID: 39604705 DOI: 10.1007/s43440-024-00683-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2024] [Revised: 11/22/2024] [Accepted: 11/25/2024] [Indexed: 11/29/2024]
Abstract
Melatonin, a hormone primarily produced by the pineal gland, exhibits a range of physiological functions that extend beyond its well-known role in regulating circadian rhythms. This hormone influences energy metabolism, modulates insulin sensitivity, and plays a significant role in controlling sleep patterns and food intake. Notably, melatonin is also synthesized in various peripheral organs, including the gastrointestinal system and pancreas, suggesting its function as a local hormone. The presence of melatonin receptors in the pancreas underscores its relevance in pancreatic physiology. Pancreatic disorders, such as diabetes mellitus (DM), pancreatitis, and pancreatic cancer, often stem from inflammatory processes. The majority of these conditions are characterized by dysregulated immune responses and oxidative stress. Melatonin's anti-inflammatory properties are mediated through the inhibition of pro-inflammatory cytokines and the activation of antioxidant enzymes, which help to mitigate cellular damage. Furthermore, melatonin has demonstrated pro-apoptotic effects on cancer cells, promoting cell death in malignant tissues while preserving healthy cells. Thus, melatonin emerges as a multifaceted agent with significant therapeutic potential for pancreatic disorders. Its ability to reduce inflammation and oxidative stress positions it as a promising adjunct therapy for conditions such as diabetes mellitus, pancreatitis, and pancreatic cancer. By modulating immune responses and enhancing cellular resilience through antioxidant mechanisms, melatonin not only addresses the symptoms but also targets the underlying pathophysiological processes associated with these disorders. This review aims to categorize and summarize the impacts of melatonin on pancreatic functions and disorders, emphasizing its potential as a therapeutic agent for managing pancreatic dysfunctions. Future research should focus on elucidating the precise mechanisms by which melatonin exerts its protective effects on pancreatic tissues and exploring optimal dosing strategies for clinical applications. The integration of melatonin into treatment regimens may enhance existing therapies and offer new hope for individuals suffering from pancreatic dysfunctions.

[PMID: 40128243 PMCID: PMC11933376 DOI: 10.1038/s41598-025-91955-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2024] [Accepted: 02/24/2025] [Indexed: 03/26/2025] Open
Abstract
Schistosomiasis drastically affects human health, where S. mansoni-induced hepatic fibrosis remains a serious problem with no available drug yet. The current study aimed to evaluate the hepatoprotective effects of Vildagliptin (Vilda), Diaminodiphenyl Sulfone (DDS), and their combination (Vilda/DDS) against S. mansoni-induced hepatic fibrosis and elucidate their underlying molecular mechanisms. S.mansoni-infected mice were administered praziquantel (PZQ) for two consecutive days, or Vilda, DDS, and Vilda/DDS for 14 consecutive days. Schistosomiasis-induced hepatic fibrosis was assessed parasitologically, biochemically, and pathologically. Results revealed that Vilda, DDS, and Vida/DDS treatments significantly reduced worm count, oogram stages, ova count, and ameliorated the granulomatous inflammatory reactions and hepatotoxicity indices. Moreover, they enhanced hepatic Nrf2/HO-1 pathway with significant increasing SOD and reducing MDA levels. Furthermore, they significantly downregulated the hepatic TLR4/NF-κB and NLRP3 inflammasome pathways leading to a significant reduction in TNF-α and caspase-1 levels which is important in the activation of IL-1β and caspase-3. Notably, significant downregulation in hepatic TGF-β1, α-SMA, and MMP-9 expressions were also recorded. In conclusion, Vilda/DDS showed antioxidant, anti-inflammatory and antifibrotic activities in comparison to either Vilda or DDS alone against S. mansoni-induced hepatic fibrosis. Therefore, Vilda/DDS is a promising approach for managing S. mansoni infection, liver fibrosis, and associated disease morbidity.

Abstract
Dapsone is a sulfone used in treating inflammatory skin conditions. Despite its widespread dermatological use, the pharmacological actions of dapsone remain poorly understood. Here, we examined how different aspects of neutrophil functions are affected by dapsone. Peripheral blood neutrophils from healthy donors were stimulated with phorbol-12-myristate-13-acetate (PMA), N-formyl-L-methionyl-L-leucyl-L-phenylalanine (fMLP), or calcium ionophore (CaI) or primed with cytokines prior to stimulation, in the presence of different concentrations of dapsone (from 10 to 50 µg/mL), followed by analyses of their survival, phenotype, and functional properties. We found that dapsone at the concentration of 50 μg/mL induced a significant neutrophil apoptotic rate during 6 h and 18 h, while other concentrations were well tolerated compared to control non-treated cells. However, dapsone significantly decreased the induced oxidative burst of neutrophils at all non-cytotoxic concentrations. Additionally, dapsone showed a dose-dependent suppression of NETosis in activated neutrophils. The production of IL-8 by dapsone-treated neutrophils was decreased under both stimulated (fMLP) and primed (TNF-α/fMLP) conditions. Moreover, dapsone inhibited the expression of CD11b/CD18, CD66, and CD89 and reversed or significantly mitigated the downregulation of CD16, CD32, CD181, CD88, and CD62L on neutrophils after priming and fMLP stimulation. In conclusion, our results indicate the complexity of dapsone actions on neutrophil functions, extending previous knowledge on the suppression of oxidative burst and IL-8 production upon neutrophils' activation. Suppressed NETosis and modulation of marker expression associated with different neutrophil functions under inflammatory conditions are new findings, not recognized previously.

Abstract
Subcutaneous adipose tissue (SAT) is the deepest component of the three-layered cutaneous integument. While mesenteric adipose tissue-based immune processes have gained recognition in the context of the metabolic syndrome, SAT has been traditionally considered primarily for energy storage, with less attention to its immune functions. SAT harbors a reservoir of immune and stromal cells that significantly impact metabolic and immunologic processes not only in the skin, but even on a systemic level. These processes include wound healing, cutaneous and systemic infections, immunometabolic, and autoimmune diseases, inflammatory skin diseases, as well as neoplastic conditions. A better understanding of SAT immune functions in different processes, could open avenues for novel therapeutic interventions. Targeting SAT may not only address SAT-specific diseases but also offer potential treatments for cutaneous or even systemic conditions. This review aims to provide a comprehensive overview on SAT's structure and functions, highlight recent advancements in understanding its role in both homeostatic and pathological conditions within and beyond the skin, and discuss the main questions for future research in the field.

Abstract
BACKGROUND AND AIM Zhumeria majdae, a unique native plant of southern Iran, has been traditionally used to treat various health issues. Preclinical studies suggest its therapeutic potential for immunological and inflammatory disorders. This study investigates the effect of Z. majdae essential oil (ZMEO) on TNBS-induced colitis in rats, focusing on the NF-κB/p38 MAPK/Nrf-2 pathway. EXPERIMENTAL PROCEDURE Forty-eight male Wistar rats were used, with all groups except the sham group receiving a single intra-rectal dose of TNBS. Three different doses of ZMEO and also 1 mg/kg dexamethasone were administered orally for 2 weeks. Colon tissue was analyzed for ulcer index, histological changes, inflammatory cytokines, apoptotic factors, and levels of NF-κB, p38 MAPK, and Nrf-2. KEY RESULTS GC-mass analysis identified 25 compounds with linalool (52.01%) and camphor (31.01%) as the major compounds in ZMEO. ZMEO ameliorated colon injuries, reduced ulcer index, and prevented the elevation of pro-inflammatory cytokines and pro-apoptotic proteins. It also increased the levels of IL-10 and Bcl-2 proteins. Furthermore, ZMEO decreased the expression of p-NF-κB and p38 MAPK while increasing the expression of pNrf-2. CONCLUSIONS ZMEO mitigates colon damage associated with IBD by suppressing inflammatory cytokines and pro-apoptotic proteins possibly through modulating the NF-κB/p38 MAPK/Nrf-2 signaling pathway.

Abstract
OBJECTIVES Osteoarthritis, a degenerative condition that results in significant morbidity, is typically managed with treatments aimed at symptom relief rather than addressing the underlying degeneration. Dapsone, recognized for its anti-inflammatory, antioxidant, antiexcitotoxic, and antiapoptotic properties, has demonstrated promising effects in various neurodegenerative diseases. This study explores the potential of dapsone to mitigate articular destruction, inflammation, and pain in rat models of osteoarthritis. METHODS Osteoarthritis was induced in rats by injecting MIA into the right knee joint. Dapsone was then administered intraperitoneally at 5, 10, or 20 mg/kg every 2 days for 2 weeks. Behavioural tests were done on days 0, 7, and 14. On day 14, the articular cartilage was histologically analysed using H&E staining. Serum levels of NF-kB, IL-1β, and TNF-α were evaluated by ELISA. RESULTS Dapsone effectively reduces pain, inflammation, and articular cartilage damage in osteoarthritis. Specifically, it improves mechanical allodynia and thermal hyperalgesia, reduces inflammatory markers (TNF-α, IL-1β, and NF-κB), and protects against cartilage destruction and chondrocyte loss, with the most significant effects at 20 mg/kg. CONCLUSIONS Dapsone effectively prevents pain, inflammation, and cartilage damage in osteoarthritis rats, suggesting its potential as a therapeutic option for managing osteoarthritis.

Abstract
Background and Objectives: Dapsone (DP) is employed in the management of various skin conditions, including autoimmune bullous diseases to non-enzymes (n-eAIBDs). This study aimed to assess the advantages and safety profile of DP treatment in n-eAIBDs patients. The evaluation focused on clinical remission, reduction in glucocorticosteroid (GCS) usage, and adverse incidents during a 12-month observation in a dermatology department at a Central European university. Materials and Methods: Our retrospective study included forty-one patients who met the inclusion criteria, comprising nineteen with pemphigus vulgaris, nine with pemphigus foliaceus, four with bullous pemphigoid, and nine with mucous membrane pemphigoid, including one patient with Brunsting-Perry pemphigoid. Patients received 25-50 mg/day of DP along with oral GCSs for a year, with a subsequent dose reduction where feasible. Results: The mean decreases in prednisone-equivalent dosages across all groups after 2, 6, and 12 months of DP treatment were 45.66%, 65.77%, and 63.03%, respectively. Throughout the 12-month observation period, 21.62% of patients experienced a relapse, while the remaining patients attained either complete or partial remission with minimal therapy. Adverse incidents were observed in 29.27% of patients; these were mild or moderate, and no severe negative effects were observed. Conclusions: DP is an effective and affordable choice to support the treatment of n-eAIBDs, but it may not be sufficient for long-term management in certain patients with severe n-eAIBDs.

Abstract
Rosacea is a complex inflammatory condition characterized by papulopustular lesions and erythema on the central face for which there is no cure. The development of rosacea is influenced by both external triggers and genetics, but the common pathophysiology is overactivation of the immune system. Here, we review the current data on proinflammatory cytokines and dysregulation of the neurovascular system as targetable components of rosacea. Amelioration of cutaneous and gastrointestinal dysbiosis and other external factors impacts the immune state and has been observed to improve rosacea. While multiple treatments exist, many patients do not achieve their goals for rosacea control and highlights an unmet need for dermatologic care. Current interventions encompass topical/oral drugs, light devices, and avoidance of triggers management. Additional understanding of the underlying pathogenesis may help us develop novel targeted therapeutic strategies to improve rosacea.

Abstract
Gynecological diseases are triggered by aberrant molecular pathways that alter gene expression, hormonal balance, and cellular signaling pathways, which may lead to long-term physiological consequences. This study was able to identify highly preserved modules and key hub genes that are mainly associated with gynecological diseases, represented by endometriosis (EM), ovarian cancer (OC), cervical cancer (CC), and endometrial cancer (EC), through the weighted gene co-expression network analysis (WGCNA) of microarray datasets sourced from the Gene Expression Omnibus (GEO) database. Five highly preserved modules were observed across the EM (GSE51981), OC (GSE63885), CC (GSE63514), and EC (GSE17025) datasets. The functional annotation and pathway enrichment analysis revealed that the highly preserved modules were heavily involved in several inflammatory pathways that are associated with transcription dysregulation, such as NF-kB signaling, JAK-STAT signaling, MAPK-ERK signaling, and mTOR signaling pathways. Furthermore, the results also include pathways that are relevant in gynecological disease prognosis through viral infections. Mutations in the ESR1 gene that encodes for ERα, which were shown to also affect signaling pathways involved in inflammation, further indicate its importance in gynecological disease prognosis. Potential drugs were screened through the Drug Repurposing Encyclopedia (DRE) based on the up-and downregulated hub genes, wherein a bacterial ribosomal subunit inhibitor and a benzodiazepine receptor agonist were the top candidates. Other drug candidates include a dihydrofolate reductase inhibitor, glucocorticoid receptor agonists, cholinergic receptor agonists, selective serotonin reuptake inhibitors, sterol demethylase inhibitors, a bacterial antifolate, and serotonin receptor antagonist drugs which have known anti-inflammatory effects, demonstrating that the gene network highlights specific inflammatory pathways as a therapeutic avenue in designing drug candidates for gynecological diseases.

Anti-inflammatory and protective effects of Aripiprazole on TNBS-Induced colitis and associated depression in rats: Role of kynurenine pathway. Int Immunopharmacol 2024; 133:112158. [PMID: 38691917 DOI: 10.1016/j.intimp.2024.112158] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Revised: 04/08/2024] [Accepted: 04/23/2024] [Indexed: 05/03/2024]
Abstract
BACKGROUND The prevalence of depression is higher in patients with inflammatory bowel disease (IBD) than in the general population. Inflammatory cytokines and the kynurenine pathway (KP) play important roles in IBD and associated depression. Aripiprazole (ARP), an atypical antipsychotic, shows various anti-inflammatory properties and may be useful in treating major depressive disorder. This study aimed to evaluate the protective effects of ARP on TNBS-induced colitis and subsequent depression in rats, highlighting the role of the KP. MATERIAL AND METHODS Fifty-six male Wistar rats were used, and all groups except for the normal and sham groups received a single dose of intra-rectal TNBS. Three different doses of ARP and dexamethasone were injected intraperitoneally for two weeks in treatment groups. On the 15th day, behavioral tests were performed to evaluate depressive-like behaviors. Colon ulcer index and histological changes were assessed. The tissue levels of inflammatory cytokines, KP markers, lipopolysaccharide (LPS), nuclear factor-kappa-B (NF-κB), and zonula occludens (ZO-1) were evaluated in the colon and hippocampus. RESULTS TNBS effectively induced intestinal damages and subsequent depressive-like symptoms in rats. TNBS treatment significantly elevated the intestinal content of inflammatory cytokines and NF-κB expression, dysregulated the KP markers balance in both colon and hippocampus tissues, and increased the serum levels of LPS. However, treatment with ARP for 14 days successfully reversed these alterations, particularly at higher doses. CONCLUSION ARP could alleviate IBD-induced colon damage and associated depressive-like behaviors mainly via suppressing inflammatory cytokines activity, serum LPS concentration, and affecting the NF-κB/kynurenine pathway.

Development of a multivariate predictive model for dapsone adverse drug events in people with leprosy under standard WHO multidrug therapy. PLoS Negl Trop Dis 2024; 18:e0011901. [PMID: 38271456 PMCID: PMC10846698 DOI: 10.1371/journal.pntd.0011901] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2023] [Revised: 02/06/2024] [Accepted: 01/04/2024] [Indexed: 01/27/2024] Open
Abstract
BACKGROUND The occurrence of adverse drug events (ADEs) during dapsone (DDS) treatment in patients with leprosy can constitute a significant barrier to the successful completion of the standardized therapeutic regimen for this disease. Well-known DDS-ADEs are hemolytic anemia, methemoglobinemia, hepatotoxicity, agranulocytosis, and hypersensitivity reactions. Identifying risk factors for ADEs before starting World Health Organization recommended standard multidrug therapy (WHO/MDT) can guide therapeutic planning for the patient. The objective of this study was to develop a predictive model for DDS-ADEs in patients with leprosy receiving standard WHO/MDT. METHODOLOGY This is a case-control study that involved the review of medical records of adult (≥18 years) patients registered at a Leprosy Reference Center in Rio de Janeiro, Brazil. The cohort included individuals that received standard WHO/MDT between January 2000 to December 2021. A prediction nomogram was developed by means of multivariable logistic regression (LR) using variables. The Hosmer-Lemeshow test was used to determine the model fit. Odds ratios (ORs) and their respective 95% confidence intervals (CIs) were estimated. The predictive ability of the LRM was assessed by the area under the receiver operating characteristic curve (AUC). RESULTS A total of 329 medical records were assessed, comprising 120 cases and 209 controls. Based on the final LRM analysis, female sex (OR = 3.61; 95% CI: 2.03-6.59), multibacillary classification (OR = 2.5; 95% CI: 1.39-4.66), and higher education level (completed primary education) (OR = 1.97; 95% CI: 1.14-3.47) were considered factors to predict ADEs that caused standard WHO/MDT discontinuation. The prediction model developed had an AUC of 0.7208, that is 72% capable of predicting DDS-ADEs. CONCLUSION We propose a clinical model that could become a helpful tool for physicians in predicting ADEs in DDS-treated leprosy patients.

Abstract
Perforin is a pore-forming protein whose normal function enables cytotoxic T and natural killer (NK) cells to kill virus-infected and transformed cells. Conversely, unwanted perforin activity can also result in auto-immune attack, graft rejection and aberrant responses to pathogens. Perforin is critical for the function of the granule exocytosis cell death pathway and is therefore a target for drug development. In this study, by screening a fragment library using NMR and surface plasmon resonance, we identified 4,4-diaminodiphenyl sulfone (dapsone) as a perforin ligand. We also found that dapsone has modest (mM) inhibitory activity of perforin lytic activity in a red blood cell lysis assay in vitro. Sequential modification of this lead fragment, guided by structural knowledge of the ligand binding site and binding pose, and supported by SPR and ligand-detected 19F NMR, enabled the design of nanomolar inhibitors of the cytolytic activity of intact NK cells against various tumour cell targets. Interestingly, the ligands we developed were largely inert with respect to direct perforin-mediated red blood cell lysis but were very potent in the context of perforin's action on delivering granzymes in the immune synapse, the context in which it functions physiologically. Our work indicates that a fragment-based, structure-guided drug discovery strategy can be used to identify novel ligands that bind perforin. Moreover, these molecules have superior physicochemical properties and solubility compared to previous generations of perforin ligands.

Insight into novel anti-mucormycosis therapies: investigation of new anti-mucormycosis laser-induced photodynamic therapy based on a sulphone bis-compound loaded silica nanoemulsion. RSC Adv 2023; 13:20684-20697. [PMID: 37435382 PMCID: PMC10331924 DOI: 10.1039/d3ra02775a] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Accepted: 06/26/2023] [Indexed: 07/13/2023] Open
Abstract
For drug delivery applications, silica nanoemulsion encapsulated with organic compounds are becoming increasingly more desirable. Therefore, the emphasis of this research was on the synthesis of a new potent antifungal drug-like candidate (1,1'-((sulfonylbis(4,1-phenylene)bis(5-methyl-1H-1,2,3-triazole-1,4-diyl))bis(3-(dimethylamino)prop-2-en-1-one), SBDMP), the chemical structure of which was confirmed on the basis of its spectral and microanalytical data. Then, silica nanoemulsion loaded with SBDMP was prepared using Pluronic F-68 as a potent surfactant. The particle shape, hydrodynamic size, and zeta potential of the produced silica nanoemulsion (with and without drug loading) were assessed. The antitumoral activity of the synthesized molecules showed the superiority of SBDMP and silica nanoemulsion with and without SBDMP loading against Rhizopus microsporous and Syncephalastrum racemosum. Subsequently, the laser-induced photodynamic inactivation (LIPDI) of Mucorales strains was determined using the tested samples. The optical properties of the samples were investigated using UV-vis optical absorption and the photoluminescence. The photosensitivity of the selected samples appeared to enhance the eradication of the tested pathogenic strains when exposed to a red (640 nm) laser light. The optical property results verified that the SBDMP-loaded silica nanoemulsion has a high depth of penetration into biological tissues due to a two-absorption photon (TAP) mechanism. Interestingly, the photosensitizing of the nanoemulsion loaded with a newly synthesized drug-like candidate, SBDMP, opens up a new route to apply new organic compounds as photosensitizers under laser-induced photodynamic therapy (LIPDT).
