Abstract
Herein, we report a transition-metal and base-free protocol to access a wide range of functionalized indenone derivatives through a HMPA-H2O-mediated oxygenative annulation of 2-alkynylphenyl-substituted p-quinone methides. This method worked effectively for most of the p-QMs investigated and the corresponding indenone derivatives were obtained in moderate to good yields. This methodology was further extended to the formal synthesis of one of the resveratrol based natural products, (±)-isopaucifloral F.

Abstract
Demonstrated herein is an unprecedented thioamide-directed cobalt (Co)-catalyzed umpolung annulation of sulfoximines enabled aryl thioamide with ynamide for the synthesis of highly substituted 2-amidoindenones. The cyclization is regioselective, making β-C-C and α-C-CO bonds. The transformation is even successful on a gram scale, exhibiting broad scope with labile functional group tolerance and constructing 43 unusual 2-amidoindenones of structural diversity. Control experiments and mechanistic investigation validate the regioselectivity outcome in this transformation.

Repeating the recursive anion engagement with the 1-indenones unfolded access to a functionally embellished cyclopenta[a]inden-8(2H)-one core and its spiroannulated analogues either directly or stepwise through tandem 1,6-Michael-type addition-6π electrocyclization and an in situ oxidation sequence.

Abstract
DNA alkylation damage, emanating from the exposure to environmental alkylating agents or produced by certain endogenous metabolic processes, affects cell viability and genomic stability. Fe(II)/2-oxoglutarate-dependent dioxygenase enzymes, such as Escherichia coli AlkB, are involved in protecting DNA from alkylation damage. Inspired by the natural product indenone derivatives reported to inhibit this class of enzymes, and a set of 2-chloro-3-amino indenone derivatives was synthesized and screened for their inhibitory properties against AlkB. The synthesis of 2-chloro-3-amino indenone derivatives was achieved from 2,3-dichloro indenones through addition-elimination method using alkyl/aryl amines under catalyst-free conditions. Using an in vitro reconstituted DNA repair assay, we have identified a 2-chloro-3-amino indenone compound 3o to be an inhibitor of AlkB. We have determined the binding affinity, mode of interaction, and kinetic parameters of inhibition of 3o and tested its ability to sensitize cells to methyl methanesulfonate that mainly produce DNA alkylation damage. This study established the potential of indenone-derived compounds as inhibitors of Fe(II)/2-oxoglutarate-dependent dioxygenase AlkB.

Abstract
The mammalian AlkB homologue-3 (AlkBH3) is a member of the dioxygenase family of enzymes that in humans is involved in DNA dealkylation repair. Because of its role in promoting tumor cell proliferation and metastasis of cancer, extensive efforts are being directed in developing selective inhibitors for AlkBH3. Here we report synthesis, screening and evaluation of panel of arylated indenone derivatives as new class of inhibitors of AlkBH3 DNA repair activity. An efficient synthesis of 2,3-diaryl indenones from 2,3-dibromo indenones was achieved via Suzuki-Miyaura cross-coupling. Using a robust quantitative assay, we have obtained an AlkBH3 inhibitor that display specific binding and competitive mode of inhibition against DNA substrate. Finally, we established that this compound could prevent the proliferation of lung cancer cell line and enhance sensitivity to DNA damaging alkylating agent.

Abstract
In this study, a novel series of 6-oxopyridazinyl benzazoles and 3, 6-dioxopyridazinyl benzazoles were prepared from the starting compounds, 2-hydrazinobenzimidazole, 2-hydrazinobenzothiazole and 2-hydrazinobenzoxazole by reaction with butyric acid derivatives and cyclic anhydrides respectively. The structures of the new compounds were confirmed by elemental analysis as well as1H NMR, IR and MS data. Some of the newly prepared compounds were subjected to evaluation for their anti-inflammatory activity using carrageenan induced paw edema at dose 100 mg kg−1using indomethacin as a reference standard and were found to be bioactive.

Abstract
A new access to indanones was discovered through a one-step nickel or iron-mediated transposition of 2-hydroxyisobenzofurans. Starting from the corresponding silylenol ethers, a new one-pot tandem isomerisation-Mukaiyama aldol process was also developed. These versatile strategies will be useful for the preparation of various types of indanones and indenones.

Abstract
New derivatives related to floctafenine were synthesized and representative examples were screened for their anti-inflammatory and analgesic activities. All compounds tested were found to exhibit anti-inflammatory and analgesic activities and some were more potent than the references, floctafenine and indomethacin, in carragenan-induced rat's paw edema. None of the tested compounds showed an ulcerogenic effect on the p-benzoquinone-induced writhing test in mice.

Abstract
The discovery of selective cyclooxygenase-2 (COX-2) inhibitors represents a major achievement of the efforts over the past few decades to develop therapeutic treatments for inflammation. To gain insights into designing new COX-2-selective inhibitors, we address the energetic and structural basis for the selective inhibition of COX isozymes by means of a combined computational protocol involving docking experiment, force field design for the heme prothetic group, and free energy perturbation (FEP) simulation. We consider both COX-2- and COX-1-selective inhibitors taking the V523I mutant of COX-2 to be a relevant structural model for COX-1 as confirmed by a variety of experimental and theoretical evidences. For all COX-2-selective inhibitors under consideration, we find that free energies of binding become less favorable as the receptor changes from COX-2 to COX-1, due to the weakening and/or loss of hydrogen bond and hydrophobic interactions that stabilize the inhibitors in the COX-2 active site. On the other hand, COX-1-selective oxicam inhibitors gain extra stabilization energy with the change of residue 523 from valine to isoleucine because of the formations of new hydrogen bonds in the enzyme-inhibitor complexes. The utility of the combined computational approach, as a valuable tool for in silico screening of COX-2-selective inhibitors, is further exemplified by identifying the physicochemical origins of the enantiospecific selective inhibition of COX-2 by alpha-substituted indomethacin ethanolamide inhibitors.

Abstract
A new application of TOPological Sub-structural MOlecular DEsign (TOPS-MODE) was carried out in anti-inflammatory compounds using computer-aided molecular design. Two series of compounds, one containing anti-inflammatory and the other containing nonanti-inflammatory compounds were processed by a k-means cluster analysis in order to design the training and prediction sets. A linear classification function to discriminate the anti-inflammatory from the inactive compounds was developed. The model correctly and clearly classified 88% of active and 91% of inactive compounds in the training set. More specifically, the model showed a good global classification of 90%, that is, (399 cases out of 441). While in the prediction set, they showed an overall predictability of 88% and 84% for active and inactive compounds, being the global percentage of good classification of 85%. Furthermore this paper describes a fragment analysis in order to determine the contribution of several fragments towards anti-inflammatory property, also the present of halogens in the selected fragments were analyzed. It seems that the present TOPS-MODE based QSAR is the first alternate general 'in silico' technique to experimentation in anti-inflammatory discovery.
