Abstract
A highly promising approach for the synthesis of functionalized 1,1-dihomoarylmethane scaffolds (bis-dimedones, bis-cyclohexanediones, bis-pyrazoles, and bis-coumarins) using g-C3N4·SO3H ionic liquid via Knoevenagel-Michael reaction has been developed and the synthesized derivatives were well characterized using spectral studies. The method involved the reaction of C-H activated acids with a range of aromatic aldehydes, in a 2 : 1 ratio catalyzed by a g-C3N4·SO3H ionic liquid catalyst. The use of g-C3N4·SO3H as a catalyst has several benefits, such as low cost, easy preparation, and high stability. It was synthesized from urea powder and chloro-sulfonic acid and was thoroughly characterized using FT-IR, XRD, SEM, and HRTEM. The present work unveils a promising and environmentally friendly method for synthesizing 1,1-dihomoarylmethane scaffolds with high yield, selectivity, and efficiency, using mild reaction conditions, no need for chromatographic separation, and short reaction times. The approach adheres to green chemistry principles and offers a viable alternative to the previously reported methods.

Abstract
A rhodium(III)-catalyzed controllable [4 + 1] and [4 + 2] annulation of N-aryl pyrazolones with maleimides as C1 and C2 synthon has been explored for the synthesis of spiro[pyrazolo[1,2-a]indazole-pyrrolidines] and fused pyrazolopyrrolo cinnolines. The product selectivity was achieved through time-dependent annulation. The [4 + 1] annulation reaction involves sequential Rh(III)-catalyzed C-H alkenylation of N-aryl pyrazolone, followed by an intramolecular spirocyclization via aza-Michael-type addition to afford spiro[pyrazolo[1,2-a]indazole-pyrrolidine]. However, prolonged reaction time converts in situ formed spiro[pyrazolo[1,2-a]indazole-pyrrolidine] into fused pyrazolopyrrolocinnoline. This unique product formation switch proceeds via strain-driven ring expansion through a 1,2-shift of the C-C bond.

Abstract
Abstract
Griseofulvin, an antifungal drug, has also shown good antiproliferative activity previously. This study was aimed to synthesize heterocyclic extension derivatives of griseofulvin and test them against cancer cell lines. Griseofulvin was hydrolyzed to afford griseofulvic acid (1) followed by hybridization with important heterocyclic moieties. Initially, the active methylene group of the 1,3-cyclohexanedione moiety in 1 was utilized to synthesize fused thiophene derivatives (4a and b) by reacting with malononitrile or ethyl cyanoacetate together with elemental sulfur. Compounds 4a and b were further converted to fused pyrimidine derivatives (5a–d) using ethyl isothiocyanate or phenyl isothiocyanate. Compound 1 was also reacted with aryldiazonium chlorides to synthesize compounds 6a and b, which were used to prepare fused thiophene derivatives (7a–d). The resulting thiophenes (7a–d) underwent cyclization to produce fused pyridazine derivatives (8a–d). In addition, fused pyridine derivatives (10a and b) were also prepared by the reaction of 4a and b with ethyl cyanoacetate using two different catalytic bases. The first was triethylamine to form 10a and b in two steps via 9a and b, and the second was sodium ethoxide to afford 10a and b in one step. Finally, 9a and b underwent cyclization in the presence of acetylacetone to yield compounds 11a and b. The structures of synthesized compounds were confirmed using IR, 1H NMR, 13C NMR, and mass spectrometry techniques. The synthesized compounds were subjected to cytotoxic screening against three tumor cell lines and presented good to excellent cytotoxic profiles. Compounds 4a and 11a showed significant inhibitory activity against the three cell lines compared to the standard drug doxorubicin.

Abstract
A series of 1-oxa-4-azaspiro[4,5]deca-6,9-diene-3,8-dione derivatives containing structural fragments of conjugated dienone have been synthesized previously by our group, however the Michael addition reaction between conjugated dienone and nucleophilic groups in the body may generate harmful and adverse effects. To reduce harmful side effects, the authors started with p-aminophenol to make 1-oxo-4- azaspirodecanedione derivatives, then utilized the Michael addition and cyclopropanation to eliminate α, β unsaturated olefinic bond and lower the Michael reactivity of the compounds in vivo for optimization. At the same time, heteroatoms are put into the molecules in order to improve the hydrophilicity of the molecules and the binding sites of the molecules and the target molecules, establishing the groundwork for improved antitumor activity. The majority of the compounds had moderate to potent activity against A549 human lung cancer cells, MDA-MB-231 breast cancer cells, and Hela human cervical cancer cells. Among them, the compound 6d showed the strongest effect on A549 cell line with IC50 of 0.26 μM; the compound 8d showed the strongest cytotoxicity on MDA-MB-231 cell line with IC50 of 0.10 μM; and the compound 6b showed the strongest activity on Hela cell line with IC50 of 0.18 μM.

Abstract
Spiro compounds are biologically active organic compounds with unique structures, found in a wide variety of natural products and drugs. They do not readily lead to drug resistance due to their unique mechanisms of action and have, therefore, attracted considerable attention regarding pesticide development. Analyzing structure-activity relationships (SARs) and summarizing the characteristics of spiro compounds with high activity are crucial steps in the design and development of new pesticides. This review mainly summarizes spiro compounds with insecticidal, bactericidal, fungicidal, herbicidal, antiviral, and plant growth regulating functions to provide insight for the creation of new spiro compound pesticides.

Abstract
An unprecedented Rh(III)-catalyzed [3+3]-spiroannulation of ketimines with cyclopropenones to access spiro[4,5]dienones has been developed. Sequential C-H/C-C bond activation and subsequent nucleophilic addition are disclosed in this process. This procedure represents the first example of the construction of spirolactams utilising cyclopropenones as 3C synthons. The remarkable advantages of this protocol are excellent chemo- and regio-selectivity, wide functional group tolerance, high reaction yields, and tolerance towards H2O.

Abstract
The enantiomerically pure, bromobenzene-derived metabolite 5 has been transformed into enone 20 using a reaction sequence involving Suzuki-Miyaura cross-coupling and Eschenmoser-Claisen rearrangement processes. Treatment of compound 20 with lithium hydroxide results in an acetonide fragmentation reaction that delivers the 4,4-disubstituted cyclohexa-2,5-dienone 21, reductive de-oxygenation of which leads to congener 22. A closely related sequence of reactions can be used to convert the same homochiral starting material 5 into compound ent-22.

Rusu A, Lungu IA, Moldovan OL, Tanase C, Hancu G. Structural Characterization of the Millennial Antibacterial (Fluoro)Quinolones-Shaping the Fifth Generation. Pharmaceutics 2021; 13:pharmaceutics13081289. [PMID: 34452252 PMCID: PMC8399897 DOI: 10.3390/pharmaceutics13081289] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Revised: 08/12/2021] [Accepted: 08/14/2021] [Indexed: 12/12/2022] Open
Abstract
The evolution of the class of antibacterial quinolones includes the introduction in therapy of highly successful compounds. Although many representatives were withdrawn due to severe adverse reactions, a few representatives have proven their therapeutical value over time. The classification of antibacterial quinolones into generations is a valuable tool for physicians, pharmacists, and researchers. In addition, the transition from one generation to another has brought new representatives with improved properties. In the last two decades, several representatives of antibacterial quinolones received approval for therapy. This review sets out to chronologically outline the group of approved antibacterial quinolones since 2000. Special attention is given to eight representatives: besifloxacin, delafoxacin, finafloxacin, lascufloxacin, nadifloxacin and levonadifloxacin, nemonoxacin, and zabofloxacin. These compounds have been characterized regarding physicochemical properties, formulations, antibacterial activity spectrum and advantageous structural characteristics related to antibacterial efficiency. At present these new compounds (with the exception of nadifloxacin) are reported differently, most often in the fourth generation and less frequently in a new generation (the fifth). Although these new compounds' mechanism does not contain essential new elements, the question of shaping a new generation (the fifth) arises, based on higher potency and broad spectrum of activity, including resistant bacterial strains. The functional groups that ensured the biological activity, good pharmacokinetic properties and a safety profile were highlighted. In addition, these new representatives have a low risk of determining bacterial resistance. Several positive aspects are added to the fourth fluoroquinolones generation, characteristics that can be the basis of the fifth generation. Antibacterial quinolones class continues to acquire new compounds with antibacterial potential, among other effects. Numerous derivatives, hybrids or conjugates are currently in various stages of research.

Abstract
Building on our previous work that discovered 1,2,4-triazole-spirodienone as a promising pharmacophore for anticancer activity, we have further diversified 1,2,4-triazole- spirodienone derivatives and synthesized a series of novel naphthalene-substituted triazole spirodienones to explore their antineoplastic activity. Of these, compound 6a possesses remarkable in vitro cytotoxic activity by arresting cell cycle and inducing apoptosis in MDA-MB-231 cells. Subsequently, acute toxicity assay showed that 6a at 20 mg/kg has no apparent toxicity to the major organ in mice. In addition, compound 6ain vivo suppressed breast cancer 4T1 tumor growth. Taken together, these results indicate that compound 6a may be a potential anticancer agent for further development.

Abstract
Many sulfonamides show anticancer activity. Based on benzenesulfonylazaspirodienone (HL-X9) identified in our previous work, we optimized the lead compound for better efficacy, thereby synthesizing a series of novel 4-(aromatic sulfonyl)-1-oxa-4-azaspiro[4.5]deca-6,9-dien-8-one derivatives through a key step of metal-catalyzed cascade cyclization. The preliminary antiproliferative tests have shown that the anticancer activities of acetyl-protected mannose-linked sulfonylazaspirodienone derivatives (7i–7l) have been greatly improved. Among them, 7j is the most potent derivative, with IC50 values of 0.17 µM, 0.05 µM, and 0.07 µM for A549, MDA-MB-231, and HeLa cell lines, respectively. Flow cytometry analysis shows that 7j arrests MDA-MB-231 cells in the G2/M phase and has a certain effect on the apoptosis of MDA-MB-231 cells. In addition, the acute toxicity of 7j was lower than that of adriamycin.

Abstract
A new class of spiroannulated pyrazolone scaffolds have been assembled from diverse o-haloaryl ynones and β-bromoalkenyl ynones via base mediated, one-pot, metal free, orthogonal strapping (tethering) mediated by the recursive anion(s) derived from pyrazolones. These convenient, preparatively useful transformations proceed through either a tandem Michael addition-intramolecular SNAr reaction or a tandem Michael addition-intramolecular AdNE process to furnish a range of pharmacophoric, diverse, spiroannulated pyrazolones from readily accessible precursors.
