Abstract
Harnessing the antioxidant cellular machinery has sparked considerable interest as an efficient anticancer strategy. Activating Nrf2, the master switch of the cellular redox system, suppresses ROS, alleviates oxidative stress, and halts cancer progression. 1,2,4-oxadiazoles are iconic direct Nrf2 activators that disrupt Nrf2 interaction with its endogenous repressor Keap1. This study introduces rationally designed 1,2,4-oxadiazole derivatives that inhibit other Nrf2 suppressors (TrxR1, IKKα, and NF-kB) thus enhancing Nrf2 activation for preventing oxidative stress and carcinogenesis. Preliminary screening showed that the phenolic oxadiazoles 11, 15, and 19 were comparable to ascorbic acid (ROS scavenging) and EDTA (iron chelation), and superior to doxorubicin against HepG-2, MDA-MB231, and Caco-2 cells. They suppressed ROS by 3 folds and activated Nrf2 by 2 folds in HepG-2 cells. Mechanistically, they inhibited TrxR1 (IC50; 13.19, 17.89, and 9.21 nM) and IKKα (IC50; 11.0, 15.94, and 19.58 nM), and downregulated NF-κB (7.6, 1.4 and 1.9 folds in HepG-2), respectively. They inhibited NADPH oxidase (IC50; 16.4, 21.94, and 10.71 nM, respectively) that potentiates their antioxidant activities. Docking studies predicted their important structural features. Finally, they recorded drug-like in silico physicochemical properties, ADMET, and ligand efficiency metrics.

Abstract
The Activator Protein-1 (AP-1) transcription factor (TF) family, composed of a variety of members including c-JUN, c-FOS and ATF, is involved in mediating many biological processes such as proliferation, differentiation and cell death. Since their discovery, the role of AP-1 TFs in cancer development has been extensively analysed. Multiple in vitro and in vivo studies have highlighted the complexity of these TFs, mainly due to their cell-type specific homo- or hetero-dimerization resulting in diverse transcriptional response profiles. However, as a result of the increasing knowledge of the role of AP-1 TFs in disease, these TFs are being recognized as promising therapeutic targets for various malignancies. In this review, we focus on the impact of deregulated expression of AP-1 TFs in CD30-positive lymphomas including Classical Hodgkin Lymphoma and Anaplastic Large Cell Lymphoma.

Abstract
Aberrant activation of NF-κB is linked with the progression of human malignancies including hepatocellular carcinoma (HCC), and blockade of NF-κB signaling could be a potential target in the treatment of several cancers. Therefore, designing of novel small molecule inhibitors that target NF-κB activation is of prime importance in the treatment of several cancers. In the present work, we report the synthesis of series of 1,3,4-oxadiazoles, investigated their anticancer potential against HCC cells, and identified 2-(3-chlorobenzo[b]thiophen-2-yl)-5-(3-methoxyphenyl)-1,3,4-oxadiazole (CMO) as the lead compound. Further, we examined the effect of CMO on cell cycle distribution (flow cytometry), apoptosis (annexin V-propidium iodide-FITC staining), and phosphorylation of NF-κB signaling pathway proteins (IκB and p65) in HCC cells. We found that CMO induced antiproliferative effect in dose- and time-dependent manner. Also, CMO significantly increased the percentage of sub-G1 cell population and induced apoptosis. Furthermore, CMO found to decrease the phosphorylation of IκB (Ser 32) in the cytoplasmic extract and p65 (Ser 536) in the nuclear extract of HCC cells. It also abrogated the DNA binding ability and transcriptional activity of NF-κB. CMO induced the cleavage of PARP and caspase-3 in a time-dependent manner. In addition, transfection with p65 small interfering RNA blocks CMO-induced caspase-3/7 activation. Molecular docking analysis revealed that CMO interacts with the hydrophobic region of p65 protein. Thus, we are reporting CMO as an inhibitor of NF-κB signaling pathway.

Abstract
![]()
Activator
protein 1 (AP-1) is a pivotal transcription factor that
regulates a wide range of cellular processes including proliferation,
apoptosis, differentiation, survival, cell migration, and transformation.
Accumulating evidence supports that AP-1 plays an important role in
several severe disorders including cancer, fibrosis, and organ injury,
as well as inflammatory disorders such as asthma, psoriasis, and rheumatoid
arthritis. AP-1 has emerged as an actively pursued drug discovery
target over the past decade. Excitingly, a selective AP-1 inhibitor
T-5224 (51) has been investigated in phase II human clinical
trials. Nevertheless, no effective AP-1 inhibitors have yet been approved
for clinical use. Despite significant advances achieved in understanding
AP-1 biology and function, as well as the identification of small
molecules modulating AP-1 associated signaling pathways, medicinal
chemistry efforts remain an urgent need to yield selective and efficacious
AP-1 inhibitors as a viable therapeutic strategy for human diseases.

Abstract
In an attempt to discover novel inhibitors of NF-kappaB and AP-1 mediated transcriptional activation utilizing the concept of chemical lead based medicinal chemistry and bioisosterism a series of 2-(2,3-disubstituted-thiophen-5-yl)-3H-quinazolin-4-one analogs was designed. A facile and simple route for the synthesis of the designed molecules was developed. Synthesized molecules were evaluated for their activity as inhibitors towards NF-kappaB and AP-1 mediated transcriptional activation in a cell line report-based assay. This series provides us with a substantial number of compounds inhibiting the activity of NF-kappaB and/or AP-1 mediated transcriptional activation. These compounds also exhibit anti-inflammatory and anti-cancer activity in in vivo models of inflammation and cancer. The 4-pyridyl group is found to be the most important pharmacophore on the third position of thiophene ring for inhibiting NF-kappaB and AP-1 mediated transcriptional activation. The relationships between the activities shown by these compounds in the in vivo and in vitro models have been established by using FVB transgenic mice model. These results suggest the suitability of the designed molecular framework as a potential scaffold for the design of molecules with inhibitory activity towards NF-kappaB and AP-1 mediated transcriptional activation, which may also exhibit anti-inflammatory and anti-cancer activity. This series of molecules warrants further study to explore their potential as therapies for use in chronic inflammatory conditions and cancer. Development of the synthetic protocol for the synthesis of this series of molecules, biological activities and a structure-activity relationship (SAR) have been discussed herein.

Abstract
Spleen tyrosine kinase (Syk) is a non-receptor-type tyrosine kinase which mediates diverse responses in haematopoietic cells. Therefore, Syk is an attractive therapeutic target, and in a study of Syk inhibitors as potentially new therapeutic agents, we discovered the 4-anilinopyrimidine-5-carboxamides. Enzyme screening indicated that an aminoethylamino moiety at the 2-position of the pyrimidine ring was important for Syk inhibitory activity, and an investigation of the substituents at the 4-position revealed that an anilino moiety substituted at the meta position was preferred. These compounds showed high selectivity for Syk, compared to other kinases, such as ZAP-70, c-Src, and PKC, and exhibited good inhibitory activities against 5-HT release from RBL-cells. Among them, compound 9a inhibited the passive cutaneous anaphylaxis reaction in mice, with an ID50 of 13 mg/kg following subcutaneous administration. These results suggest that our compounds are worthy of further evaluation as new anti-allergic agents.

Abstract
We have developed novel orally active quinazoline analogues as inhibitors of AP-1 and NF-kappaB mediated transcriptional activation. Among the derivatives prepared, 1-[2-(2-thienyl)quinazolin-4-ylamino]-3-methyl-3-pyrroline-2,5-dione (10) showed significant activity in an adjuvant-induced arthritis rat model by reducing the swelling by 65% in the non-injected foot. The synthesis, structure-activity relationship, and in vivo activity are described.

Abstract
Several analogues of ethyl 2-[(3-methyl-2,5-dioxo(3-pyrrolinyl))amino]-4-(trifluoromethyl)pyrimidine-5-carboxylate (1) were synthesized and tested as inhibitors of AP-1 and NF-kappaB mediated transcriptional activation in Jurkat T cells. From our SAR work, ethyl 2-[(3-methyl-2,5-dioxo(3-pyrrolinyl))-N-methylamino]-4-(trifluoromethyl)-pyrimidine-5-carboxylate was identified as a novel and potent inhibitor.
