Antiinflammatory photodynamic therapy potential of polyoxyethylene-substituted perylene diimide, nitrocatechol, and azo dye

Photodynamic therapy (PDT) applications enable light-controlled activation of drug candidates instead of their constitutive activities to prevent undesired side effects associated with their constant activities. A specific wavelength of light is utilized to enable electron mobility in the chemical structure, which results in differential activities that may alter cell viability and cellular functions. Canonical photodynamic therapy applications mostly focus on cytotoxicity-based antimicrobial and anticancer properties of the PDT agents.

Mmu-miR-125b overexpression suppresses NO production in activated macrophages by targeting eEF2K and CCNA2

MicroRNAs have been shown to be important regulators of the immune response and the development of the immune system. It was reported that microRNA-125b (miR-125b) was down-regulated in macrophages challenged with endotoxin.

Glucocorticoid-dependent expression of IAP participates in the protection against TNF-mediated cytotoxicity in MCF7 cells

Glucocorticoid receptor (GR) activation has been associated with breast cancer cell survival in vitro. Glucocorticoid (GC)-dependent protection against tumor necrosis factor (TNF)-induced cell death has been well characterized in MCF7 luminal A breast cancer cells.

Whole-cell fungal-mediated structural transformation of anabolic drug metenolone acetate into potent anti-inflammatory metabolites

Study indicated that F. lini was able to catalyze dehydrogenation reactions selectively. Structures of compounds 1–14 were determined through NMR, HRFAB-MS, and IR spectroscopic data. Compounds 1–14 were identified as non-cytotoxic against BJ human fibroblast cell line (ATCC CRL-2522). Metabolite 5 (81.0 ± 2.5%) showed a potent activity against TNF-a production, as compared to the substrate 1 (62.5 ± 4.4%). Metabolites 2 (73.4 ± 0.6%), 8 (69.7 ± 1.4%), 10 (73.2 ± 0.3%), 11 (60.1 ± 3.3%), and 12 (71.0 ± 7.2%), also showed a good inhibition of TNF-a production. Compounds 3 (IC50 = 4.4 ± 0.

Báo cáo khoa học: IFN-c enhances TRAIL-induced apoptosis through IRF-1

Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is amember of theTNFfamilyandapotent inducer of apoptosis. TRAIL has been shown to effectively limit tumor growthin vivowithout detectable cytotoxic side-effects. Interferon (IFN)-coften modulates the anticancer activities of TNF family members including TRAIL. How-ever, little is known about the mechanism. To explore the mechanism, A549, HeLa, LNCaP, Hep3B andHepG2 cells were pretreated with IFN-c, and then exposed to TRAIL.
