METHODS: A new synthetic compound, 2-(1,1-dimethyl-1H-benzo[e]indol-2-yl)-3-((2-hydroxyphenyl)amino) acrylaldehyde, abbreviated as DBID, was prepared through the reaction of 2-(diformylmethylidene)-1,1- dimethylbenzo[e]indole with 2-aminophenol. The chemical structure of the synthesized compound was characterized by 1H NMR, 13C NMR and APT-NMR spectroscopy and confirmed by elemental analysis (CHN). The compound was screened for the antiproliferation effect against colorectal cancer cell line, HCT 116 and its possible mechanism of action was elucidated. To determine the IC50 value, the MTT assay was used and its apoptosisinducing effect was investigated.
RESULTS: DBID inhibited the proliferation of HCT 116 cells with an IC50 of 9.32 µg/ml and significantly increased the levels of caspase -8, -9 and -3/7 in the treated cells compared to untreated cells. Apoptosis features in HCT 116 cell was detected in treated cells by using the AO/PI staining that confirmed that the cells had undergone remarkable morphological changes in apoptotic bodies. Furthermore, this changes in expression of caspase -8, -9 and -3 were confirmed by gene and protein quantification using RT-PCR and western blot analysis, respectively.
CONCLUSION: The current study showed that the DBID compound has demonstrated chemotherapeutic activity which was evidenced by significant increases in the expression and activation of caspase and exploit the apoptotic signaling pathways to trigger cancer cell death.
METHODS: Different electronic databases were searched in a non-systematic way to find out the literature of interest.
RESULTS: The level of ferritin rises in many inflammatory conditions including autoimmune disorders. However, in four inflammatory diseases (i.e., adult-onset Still's diseases, macrophage activation syndrome, catastrophic antiphospholipid syndrome, and sepsis), high levels of ferritin are observed suggesting it as a remarkable biomarker and pathological involvement in these diseases. Acting as an acute phase reactant, ferritin is also involved in the cytokine-associated modulator of the immune response as well as a regulator of cytokine synthesis and release which are responsible for the inflammatory storm.
CONCLUSION: This review article presents updated information on the role of ferritin in inflammatory and autoimmune diseases with an emphasis on hyperferritinaemic syndrome.
METHODS: Pharmaceutical emulsion holds a significant place as a primary choice of oral drug delivery system for lipophilic drugs used in pediatric and geriatric patients. Pharmacokinetic studies on nanoemulsion mediated drugs delivery approach indicates practical feasibility in regards to their clinical translation and commercialization.
RESULTS: This review article is to provide an updated understanding on pharmacokinetic and pharmacodynamic features of nanoemulsion delivered via oral, intravenous, topical and nasal route.
CONCLUSION: The article is of huge interest to formulation scientists working on range of lipophilic drug molecules intended to be administered through oral, intravenous, topical and nasal routes for vivid medical benefits.
