[0002] Antifibrotic (1 E)-1-[4-(trifluoromethyl)phenyl]pentan-1-one oxime derivatives

[0003] Field of the invention

[0004] The present invention is directed to compositions and methods for the prevention, and / or treatment of inflammation in various tissues and organs. In particular, embodiments of the present invention relate to the use of Sigma-1 receptor (SIR) agonists for use in the prevention and / or treatment of excessive production of pro-inflammatory cytokines in a medical or disease condition. Fluvoxamine has been claimed in patent applications WO2015 / 118365 (PCT / HU2015 / 000014) as a SIR agonist, and it has shown anti-inflammatory properties.

[0005] Fluvoxamine is an antidepressant drug that crosses the blood-brain barrier (BBB) and acts on the central nervous system (CNS). The CNS activity is not a desired effect in anti-inflammatory treatment outside the brain. Transport / permeability of a compound towards the CNS can be decreased by enhancement of polarity and reducing lipophilicity. Metabolites forming during the drug's metabolism in the body could be suitable for treating inflammation due to their enhanced polarity, but these compounds have poor absorption and fast elimination properties. Thus, we have developed metabolites of the drug and prodrugs of its metabolites having anti-inflammatory activity with no, or minimal CNS activity. In a preferred embodiment, the inflammation modulators are metabolites, prodrugs or derivatives of metabolites of fluvoxamine.

[0006] Background art

[0007] The human body responds to various injuries and stimuli, including pathogens, toxic substances or any harmful agent. Inflammation is a crucial biological process functioning as part of the immune system's defense mechanism to eliminate injury, clear out damaged tissue, and initiate tissue repair. Inflammation occurs in a highly regulated and meticulously choreographed manner; it may start rapidly, become severe in days, or can progress to a chronic state which lasts for prolonged periods, even for months or years.

[0008] The prevalence of diseases associated with chronic inflammation has increased persistently for the next 30 years in the United States. In 2000, nearly 125 million Americans were living with chronic conditions, and 61 million (21%) had more than one. Worldwide, 3 of 5 people die due to chronic inflammatory diseases like stroke, chronic respiratory diseases, heart disorders, cancer, obesity, and diabetes.

[0009] There are several chronic inflammatory disorders with no cure. Most are managed with symptomatic therapy; however, in some cases, besides life-long anti-inflammatory medication, the disease progresses; therefore, novel treatments are needed.

[0010] The hallmarks of inflammation are the infiltration of the primary inflammatory cells such as macrophages, lymphocytes, and plasma cells in the tissue site, producing inflammatory cytokines such as interleukin-1 beta (IL-1 B), IL-6 or tumor necrosis factor-alpha (TNF- a), growth factors, enzymes and hence contributing to the progression of tissue damage

[0011] The Sigma-1 receptor (S1 R) is a highly conserved chaperone protein primarily studied in the central nervous system, but it is also expressed in peripheral tissues [Cureus. 2023 Mar 4;15(3):e35756. doi: 10.7759 / cureus.35756], S1 R modulates several cellular processes, including calcium signaling, inflammation, oxidative stress, and apoptosis. It primarily resides in the endoplasmic reticulum membrane and acts as a chaperone, influencing the activity of ion channels, receptors, and signaling pathways.

[0012] Activation of the S1 R has been shown to modulate systemic and local inflammation and reduce the production of proinflammatory cytokines, such as TNF-a, IL-1 p, and ilL-6. This is often linked to inhibiting the NF-KB signaling pathway, a critical regulator of inflammatory responses. The NF- KB pathway acts as a bridge between toll-like receptor (TLR)TLR2 activation and the inflammatory response. Once TLR2 is activated, it initiates a signaling cascade that activates NF-KB, resulting in the transcription of pro-inflammatory genes that exacerbate inflammation. TLRs are also found in non-immune cells such as kidney tubular epithelial systemic and local inflammation, cells, endothelial cells, podocytes, and mesangial cells ront. (Cell. Neurosci., 20 September 2018 Sec. Non-Neuronal Cells Volume 12 - 2018 | https: / / doi.org / 10.3389 / fncel.2018.00314).

[0013] Fluvoxamine showed promising anti-inflammatory effects in various preclinical models. In activated microglial cells TNF-a level can be reduced fluvoxamine treatment Sci. Rep. 2017;7(1):1-17. doi: 10.1038 / s41598-017-04968-z. In another study fluvoxamine diminished high expression of IL-1 B and TNF- TNF-a in rodent arthritis model (Environ Sci Pollut Res Int. 2023 Feb;30(6):14580-14591. doi: 10.1007 / s11356-022-23142-1 and also in liver inflammatory induced by bile duct ligation Heliyon. 2022 Dec 15;8(12):e12344. doi: 10.1016 / j.heliyon.2022.e12344. and experimental colitis (Int J Mol Sci. 2020 Jun 5;21(11):4046. doi: 10.3390 / ijms21114046.). These findings suggest that the S1 R could be a novel target for the development of anti-inflammatory drugs. (Biomolecules. 2022 Feb 25;12(3):363. doi: 10.3390 / biom 12030363).

[0455] Biological results

[0456] To examine the cellular toxicity of the chemical entities, we performed cellular examinations on NIH3T3 as a non-tumorous control. We found that the compounds do not show toxic effects on the cell lines NIH3T3 mentioned above.

[0457] To examine the cellular toxicity of the chemical entities, preferably Compound 1 (example 23) and Compound 2 (example 3), specifically in human kidney epithelial cells, we performed MTT and LDH assay to test cell viability. Compound 1 did not show toxic effects applied in a dose of 10 uM or below, while Compound 2 showed no toxic effects applied in a dose of 5 uM or below.

[0458] To assess whether S1 R activation can mitigate tubular inflammation, we examined the mRNA expression of IL1 B, IL6, TNFalpha, TLR2, TLR4 NFKB1 and MCP-1, after LPS induction in HK-2 cells. LPS treatment markedly increased TLR2 and TLR4 expression, leading to a subsequent rise in NFKB1 and proinflammatory cytokine levels. Compound-1 and Compound-2 treatment reduced the LPS-induced increase in the mRNA expression of all genes except of MCP-1
