Uses

Used in Pharmaceutical Industry:
SU 4942 is used as an anti-inflammatory agent for its capacity to reduce the production of pro-inflammatory cytokines, which are key mediators in inflammatory responses. This makes it a promising candidate for the treatment of inflammatory diseases where excessive inflammation can lead to tissue damage and chronic conditions.
Used in Oncology:
In the field of oncology, SU 4942 is utilized as an anti-tumor agent due to its ability to suppress the growth of tumor cells. Its potential in treating certain types of cancer is attributed to its mechanism of action, which involves the inhibition of p38 MAPK, a protein kinase that plays a role in cell growth and division.
Used in Drug Development:
SU 4942 is employed in the development of novel therapeutic interventions for conditions characterized by excessive inflammation or uncontrolled cell growth. Its targeted approach to inhibiting p38 MAPK suggests that it could be a component of new drugs aimed at treating specific inflammatory and oncogenic disorders, potentially offering more effective and less toxic treatments compared to existing options.

New cell cycle checkpoint pathways regulators with 2-Oxo-indoline scaffold as potential anticancer agents: Design, synthesis, biological activities and in silico studies

3-Arylidene-2-oxo-indoline derivatives are at the heart of a wide range of clinically, medicinally and biologically important compounds among the 2-oxo-indolines. A number of 3-arylidene-2-oxo-indolines have been approved for clinical application. Accordi

Inversion kinetics of someE/Z3-(benzylidene)-2-oxo-indoline derivatives and theirin silicoCDK2 docking studies

The structure-based design of some CDK2 inhibitors with a 3-(benzylidene)indolin-2-one scaffold as potential anticancer agents was realized. Target compounds were obtained asE/Zmixtures and were resolved to correspondingE- andZ-diastereomers.In silicostudies using MOE 2019.01 software revealed better docking on the targeted enzyme for theZ-diastereomer compared to theE-one. A time-dependent kinetic isomerization study was carried out for the inversion ofE/Zdiastereomers in DMSO-d6at room temperature, and were found to obey the first order kinetic reactions. Furthermore, a determination of the kinetic inter-conversion rate order by graphical analysis method and calculation of the rate constant and half-life of this kinetic process were carried out. For the prediction of the stability of the diastereomer(s), a good multiple regression equation was generated between the reaction rates of isomerization and some QM parameters with significantpvalue.

Copper(i)/Ganphos catalysis: enantioselective synthesis of diverse spirooxindoles using iminoesters and alkyl substituted methyleneindolinones

A copper-catalyzed asymmetric 1,3-dipolar cycloaddition of glycine iminoesters with alkyl substituted 3-methylene-2-oxindoles is described. By usingde novodesign of P-stereogenic phosphines as ligands, spiro[pyrrolidin-3,3'-oxindole]s are generated in good to excellent yields with high asymmetric induction. A further reduced catalyst loading of 0.1 mol% is sufficient to achieve a satisfactory enantioselectivity of 90% ee. The DFT calculations suggest the second Michael addition of the 1,3-dipole to be the rate- andenantio-determining step. A key feature of this 1,3-dipolar cycloaddition is the wide substrate applicability, even with alkyl aldehyde-derived azomethine ylide; thus it has streamlined a highly enantioselective access to a new class of antiproliferative agents, MDM2-p53.

An enantioselective hetero-Diels-Alder reaction of alkylidene oxindoles and 2-aza-3-silyloxy-1,3-butadienes, catalyzed by divalent transition metal complexes with N, N ′-dioxide ligands offered an efficient access to natural-product-based 3,3′-piperidinoyl spirooxindole class of small molecules. exo -Cycloadducts formed via stereospecific cycloaddition with Z -olefin displayed potent activity in modulation of hedgehog pathway.

Synthesis of (E)-3-Alkylideneindolin-2-ones by an Iron-Catalyzed Aerobic Oxidative Condensation of Csp3–H Bonds of Oxindoles and Benzylamines

A novel synthetic route for the construction of (E)-3-alkylideneindolin-2-ones through iron-catalyzed aerobic oxidative condensation of oxindoles with benzylamines has been developed. This oxidative reaction involves a sequence of C–H activation, amine self-condensation, nucleophilic addition, and C–C double bond formation. The synthetic importance of this protocol has been demonstrated by preparing tyrosine kinase inhibitors, anticonvulsant and antitumor agents, and other valuable 3-alkylideneindolin-2-one derivatives. Key intermediates are isolated and a plausible mechanistic pathway for the reaction has been discussed.

Photoredox asymmetric catalytic enantioconvergent substitution of 3-chlorooxindoles

An enantioconvergent substitution of 3-substituted 3-chlorooxindoles with N-aryl glycines under visible light irradiation is reported. A transition-metal-free cooperative catalysis platform with a dicyanopyrazine-derived chromophore (DPZ) as a photoredox catalyst and a chiral Br?nsted acid catalyst is effective for these transformations, which involve a single-electron transfer redox step and an enantioselective radical coupling. A variety of valuable chiral 3-aminomethylene-3-substituted oxindoles can be directly synthesized with high yields and enantioselectivities.

Chalcone scaffolds as photofunctional hybrid material of indolin-2-one-functionalized siloxy framework for optical sensing of Cu2+

Owing to their easy approachability and high degree of structural and functional diversity, many multicomponent reactions such as 1,3-dipolar cycloaddition have been a rich source of conjugated π-systems, functionalised chromophores and active molecules. Despite their high potential for investigation and practical benefits, few products have thus far been scrutinized for their metal sensing abilities. In the present study, indolin-2-one chalcones bearing siloxy molecular systems were synthesized by a [2+3] cycloaddition-based reaction sequence. A designed chemosensor exhibited an optical (absorption spectra) response toward Cu2+ ions in an acetonitrile solution. Different aspects of the sensing phenomena such as selectivity and association constants were studied in detail using UV-vis spectroscopy. The calibration plot was linear (R2 = 0.9966) over a large range of Cu2+ ion concentrations (10 μM). This novel effort has initiated a well-organized method for the efficient improvement of cation sensors with triazole for detecting heavy metal pollutants in environmental and healthcare fields on a large scale.

Natural α-methylenelactam analogues: Design, synthesis and evaluation of α-alkenyl-γ and δ-lactams as potential antifungal agents against Colletotrichum orbiculare

In our continued efforts to improve the potential utility of the α-methylene-γ-lactone scaffold, 62 new and 59 known natural α-methylenelactam analogues including α-methylene-γ-lactams, α-arylidene-γ and δ-lactams, and 3-arylideneindolin-2-ones were synthesized as the bioisosteric analogues of the α-methylenelactone scaffold. The results of antifungal and cytotoxic activity indicated that among these derivatives compound (E)-1-(2, 6-dichlorobenzyl)-3-(2-fluorobenzylidene) pyrrolidin-2-one (Py51) possessed good selectivity with the highest antifungal activity against Colletotrichum orbiculare with IC50?=?10.4?μM but less cytotoxic activity with IC50?=?141.2?μM (against HepG2 cell line) and 161.2?μM (against human hepatic L02?cell line). Ultrastructural change studies performed by transmission electron microscope showed that Py51 could cause important cell morphological changes in C.?orbiculare, such as plasma membrane detached from cell wall, cell wall thickening, mitochondria disruption, a dramatic increase in vacuolation, and eventually a complete loss in the integrity of organelles. Significantly, mitochondria appeared one of the primary targets, as confirmed by their remarkably aberrant morphological changes. Analysis of structure–activity relationships revealed that incorporation of the aryl group into the α-exo-methylene and the N-benzyl substitution increased the activity. Meanwhile, the α-arylidene-γ-lactams have superiority in selectivity over the 3-arylideneindolin-2-ones. Based on the results, the N-benzyl substituted α-(2-fluorophenyl)-γ-lactam was identified as the most promising natural-based scaffold for further discovering and developing improved crop-protection agents.
