Catalyst-Free Three-Component Synthesis, Antibacterial, Antifungal, and Docking Studies of Spiroindoline Derivatives

A sequence of functionalized 1 ‘ H-spiro-[indoline-3,5 ‘-pyrimido[4,5-b]quinoline] – 2,2 ‘,4 ‘ (3 ‘ H,10 ‘ H)-trione derivatives have been synthesized by a catalyst-free three-component reaction of barbituric acid with arylamines and isatin under aqueous conditions. Neutral reaction conditions, high yields, and operational simplicity are the important features of the present protocol. The molecular docking studies of all the synthesized compounds were performed with jackbean urease (PDB ID: 3LA4). The results suggest that the compounds 4a-4j showed good binding affinities with the active site of jackbean urease having an inhibition constant Ki = 76.26 nm. This study offers the first example of the exhibition of urease inhibitory potential by spiro indoline derivatives paying route to develop more potent anti-urease compounds of medicinal and agricultural interest. The selected compounds 4a and 4j were evaluated for antimicrobial studies.

Electrochemical Total Synthesis of Pyrrolophenanthridone Alkaloids: Controlling the Anodically Initiated Electron Transfer Process

Electrochemical intramolecular C(sp(2))-H cross-coupling and dehydrogenative indole synthesis were developed. Both reactions were initiated by anodic oxidation of the same electron-rich indoline moiety, but the product selectivity was controlled by different electron-transfer processes. Intramolecular cross-coupling was achieved by the generation of a strong electrophilic radical cation intermediate in the MeNO2-HFIP-LiClO4 system. Indole formation was accomplished through benzylic oxidation and continuous deprotonation. We applied these reactions to the total synthesis of natural pyrrolophenanthridone alkaloids.

Synthesis and characterization of apHand photoresponsive copolymer of acrylamide and spiropyran

In this research, the solution properties of acrylamide and spiropyran acrylate copolymers were investigated. Spiropyran acrylate was synthesized by the reaction of 1 ‘,3 ‘,3 ‘-trimethyl-6-hydroxyspiro(2H-1-benzopyran-2,2 ‘-indoline) and acryloyl chloride. The free radical solution polymerization was used to attain a specialty responsive polymer. Characterization was carried out using nuclear magnetic resonance (NMR), Fourier-transform spectroscopy (FTIR), and ultraviolet-visible spectroscopy (UV-vis). The FTIR and NMR results showed that the copolymer synthesis was successful, and the copolymer contained spiropyran monomer. UV analyses indicated that the photoresponsive behavior of the copolymer in the protic and aprotic solvents was quite the opposite, and the polymer absorption spectrum in the basic aqueous solutions was red-shifted.

Preparation and analysis of photochromic behavior of carboxymethyl chitin derivatives containing spiropyran moieties

1MODIFIER LETTER PRIME-(2-Acryloxyethyl)-3,3MODIFIER LETTER PRIME-dimethyl-6-nitrospiro[2 H-1-benzopyran-2,2MODIFIER LETTER PRIME-indoline] (SPA) was synthesized and grafted onto a water-soluble carboxymethyl chitin (CMCH) macromolecule to prepare a photochromic copolymer (CMCH-g-SPA). The structure of CMCH-g-SPA was characterized by Fourier-transform infrared (FT-IR) spectroscopy, thermogravimetric (TG) analysis, X-ray diffraction (XRD) analysis, water-solubility evaluation, and UV-vis spectroscopy. XRD patterns of CMCH-g-SPA revealed that grafting copolymerization disrupts the CMCH semicrystalline structure, thus improving water solubility. UV-vis spectroscopy results supported the negative photochromic behavior of the merocyanine (MC) form of CMCH-g-SPA (CMCH-g-MCA) present in a water solution of the target copolymer. In addition to high solvent polarity, the intermolecular and intramolecular electrostatic attraction between the indolenine cation and the COO(-)anion were found to be influencing factors, which stabilize these MC form of spiropyran groups grafted onto CMCH. In a water solution, visible light bleaching was completed over a short period (8 minutes) under artificial visible light irradiation and the thermal coloration reaction, whose rate constant at 25 degrees C was 4.64 x 10(-4) s(-1), which fit the first-order reaction equation. After ten photochromic cycles in water solution, the relative absorption intensity of CMCH-g-MCA decreased by 7.92%.

Several molecules have demonstrated a considerable cytotoxicity against A549, HEK293T, MCF7 and VA13 cancer cell lines. The possible mechanism of anticancer activity of the synthesized compounds based on literature data may be the inhibition of p53/MDM2 interaction; however, we did not observe significant p53 activation using a reporter construction in A549 cell line in the relevant concentration range.

Spirofused tetrahydroisoquinoline-oxindole hybrids as a novel class of fast acting antimalarial agents with multiple modes of action

Molecular hybridization of privileged scaffolds may generate novel antiplasmodial chemotypes that display superior biological activity and delay drug resistance. In the present study, we describe the in vitro activities and mode of action of 3 ‘ ,4 ‘ -dihydro-2 ‘ H-spiro[indoline-3,1 ‘ -isoquinolin]-2-ones, a novel class of spirofused tetrahydroisoquinoline-oxindole hybrids, as novel antimalarial agents. Whole cell phenotypic screening of these compounds identified (14b), subsequently named (+/-)-moxiquindole, as the most potent compound in the current series with equipotent antiplasmodial activity against both chloroquine sensitive and multidrug resistant parasite strains with good selectivity. The compound was active against all asexual stages of the parasite including inhibition of merozoite egress. Additionally, (+/-)-moxiquindole exhibited significant inhibitory effects on hemoglobin degradation, and disrupted vacuolar lipid dynamics. Taken together, our data confirm the antiplasmodial activity of (+/-)-moxiquindole, and identify 3 ‘ 4 ‘ -dihydro-2 ‘ H-spiro[indoline-3,1 ‘ -isoquinolin]-2-ones as a novel class of antimalarial agents with multiple modes of action.

Steering the antitumor drug discovery campaign towards structurally diverse indolines

Indoline framework is often perpended as a privileged heterocycle present in medicinally valuable compounds of natural and synthetic origin. This review article presents the rational approaches/strategies employed for the design of anticancer indolines along with the structure activity relationship and mechanistic insights revealed in the in-vitro and in-vivo assays. The chemist has always been fascinated towards the indoline ring for the construction of antitumor scaffolds owing to its versatility as evidenced by its existence in scaffolds inducing antiproliferative effects via diverse mechanisms. To the delight of medicinal chemist, the applicability of indoline has also been expanded towards the design of dual inhibitors (multitargeting anticancer agents) as well as PROTACS. Overall, it can be concluded that indoline moiety is a magic bullet and the scaffolds containing this ring are foraying towards detailed preclinical and clinical stage investigations by leaps and bounds.
