SPECTROCHIMICA ACTA PART A-MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2022; 280:121530. [PMID: 35752037 DOI: 10.1016/j.saa.2022.121530] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Revised: 06/12/2022] [Accepted: 06/16/2022] [Indexed: 10/31/2022]
Abstract
The present work encompasses a combined experimental and theoretical investigation of the molecular structure, vibrational wavenumbers, electronic structure at the ground and electronic excited states, molecular electrostatic potential surface of 7-(Trifluoromethyl)-1H-indole-2-carboxylic acid (TICA) and possibility of the title molecule as an aromatase inhibitor using molecular docking and molecular dynamic simulations. A stable conformer has been obtained using potential energy scans by varying appropriate dihedral angles. The obtained minimum energy conformer was further optimized at the 6-311++G (d, p) basis set by applying the most accepted B3LYP functional. A good agreement between experimental and calculated normal modes of vibration has been observed. The hydrogen-bonded interaction between two monomeric units of TICA has been investigated using NBO,QTAIM, and NCI (noncovalent interactions) analysis. Molecular docking of TICA with human placental aromatase (PDB ID: 3S79) reveals the formation of polar hydrogen bonds as well as hydrophobic interactions between the ligand and the protein, right in the binding cavity. TICA satisfies all pharmacokinetic filters (Lipinski rule of five, the Veber rule, Ghose rule, Egan rule, as well as the Muegge rule) and has a high bioavailability score of 0.85. Dynamic stability of the ligand within the binding pocket of the target protein has been confirmed by 100 ns molecular dynamics simulation results. The present study provides an excellent starting point for additional in vivo research, and TICA may eventually serve as a significant therapeutic candidate for the treatment of breast cancer.

Abstract
Radiation therapy (RT) evolved to be a primary treatment modality for cancer patients. Unfortunately, the cure or relief of symptoms is still accompanied by radiation-induced side effects with severe acute and late pathophysiological consequences. Inhibitors of cyclooxygenase-2 (COX-2) are potentially useful in this regard because radioprotection of normal tissue and/or radiosensitizing effects on tumor tissue have been described for several compounds of this structurally diverse class. This review aims to substantiate the hypothesis that antioxidant COX-2 inhibitors are promising radioprotectants because of intercepting radiation-induced oxidative stress and inflammation in normal tissue, especially the vascular system. For this, literature reporting on COX inhibitors exerting radioprotective and/or radiosensitizing action as well as on antioxidant COX inhibitors will be reviewed comprehensively with the aim to find cross-points of both and, by that, stimulate further research in the field of radioprotective agents.

Abstract
The in vitro and in silico analysis of Rubus fairholmianus acetone extract for antioxidant, antiproliferative, and anti-inflammatory activity led to the isolation of six compounds. Amongst all the six isolated compounds tested, 1-(2-hydroxyphenyl)-4-methylpentan-1-one (compound 1) and 2-[(3-methylbutoxy) carbonyl] benzoic acid (compound 2) were found to be more active in inhibiting BRCA and COX target proteins, which also showed the better results for DPPH and ABTS radical scavenging assays. The promising results of this investigation emphasize the importance of using R. fairholmianus in the treatment of radical generated disorders mainly cancer and other inflammatory diseases.

Abstract
Preclinical Research This study describes the anti-inflammatory activities of two semisynthesized melatonin (MT) derivatives, benzoyl-melatonin (BMT) and acetyl-melatonin (AMT), on the production of pro-inflammatory mediators in lipopolysaccharide (LPS)-stimulated macrophage cells (RAW 264.7) and their antinociceptive effects in mice. The MT derivatives inhibited production of nitric oxide NO and prostaglandin E2 in LPS-stimulated RAW264.7 cells in a dose-dependent manner with IC50 values lower than those of MT. BMT produced increased tail flick latency time, decreased number of writhes, and reduced nociceptive response in mice when compared with AMT and MT. BMT and AMT had enhanced anti-inflammatory effects in LPS-stimulated RAW264.7 compared with MT. However, in mouse studies BMT exhibited the highest potency as an anti-inflammatory agent and was longer-acting as an antinociceptive compound compared with AMT or MT, suggesting that BMT has potential as an anti-inflammatory and analgesic compound.

Abstract
A series of novel indomethacin analogues with carbaboranes as three-dimensional substitutes for the chlorophenyl ring have been prepared. Their cyclooxygenase (COX) inhibition and enzyme selectivity has been tested and compared to the corresponding adamantyl analogues. Surprisingly, only the ortho-carbaborane derivatives were active compounds. Preliminary biological studies gave an interesting insight into the validity of employing carbaboranes as pharmacophores.

Abstract
Quantitative structure-activity relationship (QSAR) studies have been performed on a combined series of 2-sulfonylphenyl-3-phenyl-indoles and 2-phenyl-3-sulfonylphenyl-indoles with a common 2,3 vicinal diaryl indole scaffold, recently reported as selective COX-2 inhibitors. This study is aimed to throw light on this, special class of diaryl heterocyclic family of selective COX-2 inhibitors. A preliminary Fujita-Ban analysis on 32 compounds provided valuable insights about the role of different substituents R1 and R2 around the 2,3 vicinal diaryl rings and R3, at position-5 of the central indole moiety in explaining their in vitro COX-2 inhibitory activity. The contribution of R1, R2, R3 towards COX-2 inhibitory activity resulted in statistically significant linear multiple regression equation with r = 0.942, r(2) = 0.888, s = 0.532 and F = 7.92, q(2) = 0.516 for 29 compounds. Fujita-Ban model shows a negative contribution of SO2NH2 and SO2CH3 at the R1 position; a negative contribution of 4-Cl, 2-Cl, 3-Cl, 3-CH3, 4-SO2CH3, 4-Br and a positive contribution of 4-OCH3, 4-CH3 substituents at the R2 position. At the R3 position a negative contribution of F, Br and a positive contribution of Cl, CH3 is encountered. In the light of our preliminary investigation that electron donating groups at the para position of R2 are conducive for COX-2 inhibitory activity from the Fujita-Ban model, we attempted to correlate the COX-2 inhibitory activity with quantum chemical descriptors of semi-empirical AM1 optimized geometries of the title compounds. Correlation analysis showed the molecular electronic descriptor, MOPAC total energy as crucial in governing COX-2 inhibitory activity of all the reported 41 compounds.

Abstract
Several indole esters were tested as inhibitors of tyrosine kinase p60(c-Src). Compound (4) was found fairly active against the enzyme with IC50 = 1.34 microM. DOCK methodology was used to asses our inhibitors for their inhibitory potency against tyrosine kinase. The docking results showed that compounds (4), (25) and (26) were bound to the active site of the enzyme Lys 295 of p60(c-Src) tyrosine kinase. Both activity and docking studies showed a parallel result, with compound (4) having a better interaction with the enzyme active site and also greater activity than the other compounds, indicating a potential role as new lead inhibitor.

Abstract
The hydroxyl radical (HO*)- and superoxide anion radical (O* (2))-scavenging activity, as well as the singlet oxygen ((1)O(2))-quenching property of N-substituted indole-2-carboxylic acid esters (INDs) were investigated by deoxyribose degradation assay, a chemiluminescence method and the electron spin resonance (ESR) spin-trapping technique. This novel group of compounds was developed as a search for cyclooxygenase-2 (COX-2)-selective enzyme inhibitors. The results obtained demonstrated that of the 16 compounds examined, five inhibited light emission from the superoxide anion radical (O* (2))-DMSO system by at least 60% at a concentration of 1 mmol/L, nine prevented the degradation of deoxyribose induced by the Fenton reaction system (range 3-78%) or scavenged hydroxyl radicals (HO*) directly (range 8-93%) and 14 showed the (1)O(2)-quenching effect (range 10-74%). These results indicate that majority of the indole esters tested possess the ability to scavenge O(-) (2) and HO radicals and to quench (1)O(2) directly, and consequently may be considered effective antioxidative agents.

Abstract
The treatment of N-acyl oxazolidinones of N-benzyl 2-indolecarboxylic acids varying in the substitution pattern of the indole ring with samarium diiodide at -78 degrees C led to the formation of two indole dimer products. The major product isolated in yields from 55 to 59% represents an unsymmetrical dimer arising from 1,4-addition to the 2-indolecarboxylic acid derivative of a possible ketyl-type radical anion intermediate originating from the reduction of the exocyclic carbonyl group of the N-acyl oxazolidinone. The minor dimer, represented by a symmetrical diketone, was produced in yields ranging from 11 to 23%. Even in the presence of an alpha,beta-unsaturated amide, dimerization was the preferred pathway rather than the formation of a gamma-keto amide. Upon treatment with acid, the unsymmetrical indole dimer cyclized to form a diindolequinone. Finally, the N-acyl oxazolidinones of pyrrole-2-carboxylic acid and 3-indolecarboxylic acid preferred in both cases to undergo C-C bond formation with an acrylamide in the presence of SmI2 rather than dimerization.

Abstract
A series of 3-(substituted-benzylidene)-1, 3-dihydro-indolin-2-thione derivatives were synthesized as modified congeners of 3-(substituted-benzylidene)-1, 3-dihydro-indolin-2-one series. All the synthesized compounds were examined for their in vitro anti-tyrosine kinase activity against p60c-Src. The activity results revealed that compounds (Z)-3-(4'-Dimethylamino-benzylidene)-1, 3-dihydro-indolin-2-thione (12) (E)-3-(2', 6'-Dichloro-benzylidene)-1, 3-dihydro-indolin-2-thione (13) and (E)-3-(3'-Hydroxy-4'-methoxy-benzylidene)-1, 3-dihydro-indolin-2-thione (19) exhibited anti-tyrosine kinase activity with IC50 value of 21.91, 21.20 and 30.92 microM, respectively. These results are comparable to PP1 [1-tert-Butyl-3-p-tolyl-1H-pyrazolo[3, 4-d]pyrimidine-4-yl-amine] (IC50=0.17 microM), which is reported as a potent and selective p60c-Src tyrosine kinase inhibitor. Some thio congeners are found to be more potent than oxo derivatives; however, no significant correlation was observed between the activity profiles of these two series. Docking program was used to investigate the docking mode of each compound at the active site. Among all of the compounds, only (Z)-3-(2'-Chloro-benzylidene)-1, 3-dihydro-indolin-2-one (8) and (E)-3-(3'-Nitro-benzylidene)-1, 3-dihydro-indolin-2-thione (16) were docked at the active site where the PP1 was embedded.

Abstract
Diketo acids such as S-1360 (1A) and L-731,988 (2) are potent and selective inhibitors of HIV-1 integrase (IN). A plethora of diketo acid-containing compounds have been claimed in patent literature without disclosing much biological activities and synthetic details (reviewed in Neamati, N. Exp. Opin. Ther. Pat. 2002, 12, 709-724). To establish a coherent structure-activity relationship among the substituted indole nucleus bearing a beta-diketo acid moiety, a series of substituted indole-beta-diketo acids (4a-f and 5a-e) were synthesized. All compounds tested showed anti-IN activity at low micromolar concentrations with varied selectivity against the strand transfer process. Three compounds, the indole-3-beta-diketo acids 5a and 5c, and the parent ester 9c, have shown an antiviral activity in cell-based assays. We further confirmed a keto-enolic structure in the 2,3-position of the diketo acid moiety of a representative compound (4c) using NMR and X-ray crystallographic analysis. Using this structure as a lead for all of our computational studies, we found that the title compounds extensively interact with the essential amino acids on the active site of IN.

Abstract
A series of novel N-substituted indole carboxylic, acetic and propionic acid esters have been prepared as possible cyclo-oxygenase-2 (COX-2) enzyme inhibitors. Compounds 20, 23 were found slightly active against COX-2. The synthesis of indole carboxylic, acetic and propionic acid esters were furnished by using dicyclohexyl carbodiimide (DCC), dimethylamino pyridine (DMAP) as carboxylate activators. N-substitution of indole esters was verified with several benzyl and benzoyl group in presence of NaH in DMF, respectively.
