Abstract
Benidipine hydrochloride (BH), a medication frequently used by the hypertension patients, acts as a calcium channel blocker. However, its effects on the macrophages have not been investigated thus far. Our goal was investigating the effect of the benidipine hydrochloride to modulate the J774.2 murine macrophage cells inflammatory activity. Our results suggest that in the absence of a standard stimulating agent (LPS) BH did not stimulate the macrophages to produce pro-inflammatory IL-12p40, TNF-α, GM-CSF and IL-6 cytokines. However, when BH was administrated to the cells in the presence of LPS as stimulating agent, it reduced the production of these pro-inflammatory cytokines. Therefore, it had anti-inflammatory activity. At the clinical setting this study suggests that BH can be utilized as hypertension drug that can suppress the inflammation associated with it.

Almatari AS, Saeed A, Abdel-Ghani GE, Abdullah MMS, Al-Lohedan HA, Abdel-Latif E, El-Demerdash A. Synthesis of Some Novel Thiophene Analogues as Potential Anticancer Agents. Chem Biodivers 2024; 21:e202400313. [PMID: 38467571 DOI: 10.1002/cbdv.202400313] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Revised: 03/08/2024] [Accepted: 03/08/2024] [Indexed: 03/13/2024]
Abstract
The aim of this study involves the synthesis novel thiophene analogues that can be used as anticancer medications through a strategic multicomponent reaction connecting ethyl 4-chloroacetoacetate (1), phenyl isothiocyanate, and a series of active methylene reagents, including ethyl acetoacetate (2), malononitrile, ethyl cyanoacetate, cyanoacetamide 6a-c, N-phenyl cyanoacetamide derivatives 13a-c, and acetoacetanilide derivatives 18. This reaction was facilitated by dry dimethylformamide with a catalytic quantity of K2CO3. The resultant thiophene derivatives were identified as 4, 8a-b, 9, 12a-d, 15a-c, and 20a-b. Further reaction of compound 4 with hydrazine hydrate yielded derivative 5, respectively. When compound 1 was refluxed with ethyl 3-mercapto-3-(phenylamino)-2-(p-substituted phenyldiazenyl)acrylate 10a-e in the presence of sodium ethoxide, it produced thiophene derivatives 12a-d. Comprehensive structural elucidation of these newly synthesized thiophene-analogues was accomplished via elemental and spectral analysis data. Furthermore, the study delves into the cytotoxicity of the newly synthesized thiophenes was evaluated using the HepG2, A2780, and A2780CP cell lines. The amino-thiophene derivative 15b exhibited an increased growth inhibition of A2780, and A2780CP with IC50 values 12±0.17, and 10±0.15 μM, respectively compared to Sorafenib with IC50 values 7.5±0.54 and 9.4±0.14. This research opens new avenues for developing thiophene-based anticancer agents.

Abstract
Poly-ε-caprolactone (PCL) has been widely used as biocompatible materials in tissue engineering. They have been used in mammalian cell proliferation to polarization and differentiation. Their modified versions had regulatory activities on mammalian macrophages in vitro. There are also studies suggesting different nanofiber diameters might alter the biological activities of these materials. Based on these cues, we examined the inflammatory activities and adherence properties of mammalian macrophages on electrospun PCL nanofibrous scaffolds formed with PCL having different nanofiber diameters. Our results suggest that macrophages could easily attach and get dispersed on the scaffolds. Macrophages lost their inflammatory cytokine TNF and IL6 production capacity in the presence of LPS when they were incubated on nanofibers. These effects were independent of the mean fiber diameters. Overall, the scaffolds have potential to be used as biocompatible materials to suppress excessive inflammatory reactions during tissue and organ transplantation by caging and suppressing the inflammatory cells.

Abstract
BACKGROUND Our group focused on a meso‑aryl substituted porphyrin molecule for its photodynamic anti-inflammatory activities on the mammalian macrophages. MATERIALS AND METHODS The porphyrine derivative previously synthesized in this study was synthesized and characterized by 1H NMR. We then examined their immunomodulatory activities based on the changes in the pro-inflammatory cytokine production levels after LPS stimulation in dark and light activated conditions. RESULTS Our results suggest that porphyrin derivative had anti-inflammatory photodynamic activity in vitro at subtoxic concentrations. Our study aims to pave a way for anti-inflammatory photodynamic therapy application in the inflammatory and autoimmune disorders. Most of the studies either focus on photodynamic cytotoxicity of the porphyrin derivatives to suppress the inflammation or porphyrin derivatives' anti-inflammatory activity without the photodynamic activation. CONCLUSION Our future studies will focus on the generation and in vitro as well as in vivo characterization of the porphyrin derivatives with anti-inflammatory photodynamic therapy applications. In this way, novel drug candidates that would have lower side effects can be generated for the patients.

Abstract
The majority of patients with depression are treated with antidepressant drugs that are in the serotonin reuptake inhibitor (SSRI) group. Different studies have been conducted on the effect of treatment with antidepressants on the level of pro-inflammatory cytokines. There have been studies on the effects of escitalopram, an SSRI group antidepressant, on the pro-inflammatory cytokine levels both in vivo and in vitro. The results of these studies do not overlap and therefore the escitalopram's effect on the immune system should be studied in more depth. In this study, we aimed to examine, in detail, the cytokine production amount by escitalopram treatment of the J774.2 macrophage cells and its intracellular mechanism of action by examining the PI3K and p38 pathways. As a result of our study, we observed that Escitalopram caused a significant increase in TNF-α, IL-6, and GM-CSF levels in mammalian macrophage cells, but did not induce IL-12p40 production. We observed that the p38 and PI3K pathways play a role in inflammation in the presence of Escitalopram.

Abstract
Fluoxetine is an antidepressant drug that is heavily preferred in the cure of depression, which is from the selective serotonin reuptake inhibitor (SSRI) group. There are many reports on the effect of fluoxetine on the immune system, and its effect on the macrophage cells has never been looked at before. We aimed to demonstrate the cytokine production potential of fluoxetine antidepressant, which is widely used in the clinic, in the J774.2 cell line and its effect on PI3K and P38 pathways. The use of fluoxetine alone in J774.2 macrophage cells showed immunostimulatory properties by inducing the production of tumor necrosis factor-α (TNF-α), interleukin (IL) IL-6, IL-12p40, and granulocyte–macrophage colony-stimulating factor (GM-CSF) cytokines. It showed anti-inflammatory properties by completely stopping the production of cytokines (IL-6, IL12p40, TNF-α, and GM-CSF) at all concentrations where LPS and fluoxetine were used together. While PI3K and P38 pathways were not effective in the immunostimulatory effect in the presence of the drug agent, we found that the PI3K and P38 pathways were influenced during their anti-inflammatory activity.

Abstract
Generation of novel and versatile immunomodulatory agents that could suppress excessive inflammation has been crucial to fight against chronic inflammatory and autoimmune disorders. Immunomodulatory agents regulate the function of immune system cells to manage their activities. Current therapy regimens for the inflammatory and autoimmune disorders rely on immunomodulatory drug molecules but they are also associated with unwanted and severe side effects. In order to prevent the side effects associated with drug molecules, the field should generate novel immunomodulatory drug candidates and further test them. Moreover, the generation of photodynamic immunomodulatory molecules would also decrease possible side effects. Photodynamic activation enables specific and localized activation of the active ingredients upon exposure to a certain wavelength of light. In our study, we generated copper-based chalcogenide structures in gel and nanoparticle form by using a water-based method so that they are more biocompatible.After their chemical characterization, they were tested on mammalian macrophages in vitro. Our results suggest that these molecules were anti-inflammatory in dark conditions and their anti-inflammatory potentials significantly increased upon xenon light treatment. We are presenting novel photodynamic immunomodulatory agents that can be used to suppress excessive inflammation in disease conditions that have been associated with excessive inflammation.

Abstract
Novel benzoylthioureas, N-((5-chloropyridin-2yl)carbamothioyl)benzamide, (HL1), N-((2-chloropyridin-3yl)carbamothioyl)benzamide, (HL2), N-((5-bromopyridin-2yl)carbamothioyl)benzamide, (HL3) and N-(Naphthalene-1-yl(phenyl)carbamothioyl)benzamide, (HL4), were synthesized. Their characterizations were made by FT-IR,1H NMR and 13C NMR spectrophotometric analysis. Single crystal X-ray diffraction measurements were conducted to determine the crystal structure of HL1 and HL4. The HL1 crystallization conditions are: in the monoclinic crystal system with P21/c space group, Z = 2, a = 8.118(2) Å, b = 12.056(3) Å, c = 13.753(4) Å. HL4crystallization conditions are: in the orthorhombic crystal system with Pbca space group, Z = 8, a = 19.597(9) Å, b = 8.270(4) Å, c = 24.299(11) Å. Investigation of photodynamic and antiinflamatory effects of these compounds revealed that they are potent adducts. Using these derivatives, mammalian macrophages were stimulated with LPS to test their anti-inflammatory activity. Based on pro-inflammatory cytokine production levels, the photodynamic anti-inflammatory activity of these adducts were found to differ. Our results showedthat benzoylthioureas can be used as potential photodynamic therapy agents to suppress the excessive inflammatory reactions encountered in autoimmune and inflammatory disorders.

Abstract
Rheumatoid arthritis, arthrosis and gout, among other chronic inflammatory diseases are public health problems and represent major therapeutic challenges. Non-steroidal anti-inflammatory drugs (NSAIDs) are the most prescribed clinical treatments, despite their severe side effects and their exclusive action in improving symptoms, without effectively promoting the cure. However, recent advances in the fields of pharmacology, medicinal chemistry, and chemoinformatics have provided valuable information and opportunities for development of new anti-inflammatory drug candidates. For drug design and discovery, thiophene derivatives are privileged structures. Thiophene-based compounds, like the commercial drugs Tinoridine and Tiaprofenic acid, are known for their anti-inflammatory properties. The present review provides an update on the role of thiophene-based derivatives in inflammation. Studies on mechanisms of action, interactions with receptors (especially against cyclooxygenase (COX) and lipoxygenase (LOX)), and structure-activity relationships are also presented and discussed. The results demonstrate the importance of thiophene-based compounds as privileged structures for the design and discovery of novel anti-inflammatory agents. The studies reveal important structural characteristics. The presence of carboxylic acids, esters, amines, and amides, as well as methyl and methoxy groups, has been frequently described, and highlights the importance of these groups for anti-inflammatory activity and biological target recognition, especially for inhibition of COX and LOX enzymes.
