Synthesis, structural characterization, and biological studies of ATBS-M complexes (M(II) = Cu, Co, Ni, and Mn): Access for promising antibiotics and anticancer agents

A new bidentate Schiff base ligand (ATBS [4-bromo-2-(thiazole-2-yliminomethyl)phenol]) was synthesized via the condensation reaction of 2-aminothiazole with 5-bromosalicylaldehyde in ethanol. The reaction of ATBS with transition metal salts of Cu(II), Co(II), Ni(II), and Mn(II) afforded the corresponding ATBS-M complexes. Results from physicochemical and spectral analyses, such as elemental analysis, infrared, UV-Vis spectroscopy, magnetic susceptibility, and molar conductance, revealed a nonelectrolytic nature with octahedral (O-h) geometry and a metal/ligand ratio of 1:2 for Cu(II), Co(II), and Ni(II), but 1:1 for the Mn(II) complex. The density functional theory (DFT) calculations are correlated very well with the proposed structure and molecular geometry of the complexes as [M(ATBS)(2)] (M = Cu, Co, and Ni) and [Mn(ATBS)(H2O)(2)]. Significantly, the prepared compounds showed strong inhibition activity for a wide spectrum of bacteria (Escherichia coli, Bacillus subtilis, and Staphylococcus aureus) and fungi (Candida albicans, Aspergillus flavus, and Trichophyton rubrum), with the ATBS-Ni complex being the most promising antibiotic agent. Molecular docking studies of the binding interaction between the title complexes with the bacterial protein receptor CYP51 revealed clear insights about the inhibition nature against the studied microorganisms, with the following order: ATBS-Cu > ATBS-Mn > ATBS-Ni > ATBS-Co for complex stability. Moreover, the cytotoxicity measurements of all prepared metal complexes against the colon carcinoma (HCT-116) and hepatocellular carcinoma (Hep-G2) cell lines showed exceptional anticancer efficacy of the complexes as compared with the free ATBS Schiff base ligand. Significantly, the results attested that ATBS-Cu is the most effective complex against HCT-116 cells, whereas ATBS-Mn has the highest cytotoxic efficiency against Hep-G2 cells. Furthermore, electronic spectra, viscosity measurements, and gel electrophoresis techniques were employed to probe the interaction of all prepared ATBS-metal complexes with calf thymus (CT)-DNA. Results confirmed that all complexes are strongly bound to CT-DNA via intercalation mode, with the ATBS-Co complex having the highest binding ability.

Novel 2-indolinone thiazole hybrids as sunitinib analogues: Design, synthesis, and potent VEGFR-2 inhibition with potential anti-renal cancer activity

Novel 2-indolinone thiazole hybrids were designed and synthesized as VEGFR-2 inhibitors based on sunitinib, an FDA-approved anticancer drug. The proposed structures of the prepared 2-indolinone thiazole hybrids were confirmed based on their spectral data and CHN analyses. The target compounds were screened in vitro for their anti-VEGFR-2 activity. All tested compounds exhibited a potent submicromolar inhibition of VEGFR-2 kinase with IC50 values ranging from 0.067 to 0.422 mu M, relative to sunitinib reference drug (IC50 = 0.075 +/- 0.002 mu M). Compounds 5, 15a, 15b, 17, 19c displayed excellent VEGFR-2 inhibitory activity, comparable or nearly equipotent to sunitinib. Compound 13b stood out as the most potent against VEGFR-2 showing IC50 value of 0.067 +/- 0.002 mu M, lower than that of sunitinib. In addition, the most potent derivatives were assessed for their anticancer activity against two renal cancer cell lines. Compound 13b (IC50 = 3.9 +/- 0.13 mu M) was more potent than sunitinib (IC50 = 4.93 +/- 0.16 mu M) against CAKI-1 cell line. Moreover, thiazole 15b displayed excellent anticancer activity against CAKI-1 cell line (IC50 = 3.31 +/- 0.11 mu M), superior to that of sunitinib (IC50 = 4.93 +/- 0.16 mu M). Thiazole 15b was also equipotent to sunitinib (IC50 = 1.23 +/- 0.04 mu M) against A498 cell line. Besides, compound 15b revealed a safety profile much better than that of sunitinib against normal human renal cells. Furthermore, a docking study revealed a proper fitting of the most active compounds into the ATP binding site of VEGFR2, rationalizing their potent anti-VEGFR-2 activity.

The design, synthesis, and in vitro trypanocidal and leishmanicidal activities of 1,3-thiazole and 4-thiazolidinone ester derivatives

Chagas and leishmaniasis are both neglected tropical diseases, whose inefficient therapies have made them remain the cause for millions of deaths worldwide. Given this, we synthesized 27 novel 1,3-thiazoles and 4-thiazolidinones using bioisosteric and esterification strategies to develop improved and safer drug candidates. After an easy, rapid and low-cost synthesis with satisfactory yields, compounds were structurally characterized. Then, in vitro assays were performed, against Leishmania infantum and Leishmania amazonensis promastigotes, Trypanosoma cruzi trypomastigotes and amastigotes, for selected compounds to determine IC50 and SI, with cytotoxicity on LLC-MK2 cell lines. Overall, 1,3-thiazoles exhibited better trypanocidal activity than 4-thiazolidinones. The compound 1f, an ortho-bromobenzylidene-substituted 1,3-thiazole (IC50 = 0.83 mu M), is the most potent of them all. In addition, compounds had negligible cytotoxicity in mammalian cells (CC50 values > 50 mu M). Also noteworthy is the examination of the cell death mechanism of T. cruzi, which showed that compound 1f induced necrosis and apoptosis in the parasite. Scanning electron microscopy analysis demonstrated that the treatment of Trypanosoma cruzi trypomastigote cells with the compound 1f at different IC50 concentrations promoted alterations in the shape, flagella and body surface, inducing parasite death. Together, our data revealed a novel series of 1,3-thiazole structure-based compounds with promising activity against Trypanosoma cruzi and Leishmania spp., broadening ways for scaffold optimization.

An extensive research on aldose reductase inhibitory effects of new 4H-1,2,4-triazole derivatives

Aldose reductase (AR) is a key enzyme, which triggers the excessive accumulation of sorbitol in insulin independent tissues leading to severe diabetes-induced microvascular complications. Substantial evidence has proven that AR inhibition is a well-established strategy to attenuate these complications. In the current work, new 2-[(4-amino-5-aryl-4H-1,2,4-triazol-3-yl)thio]-N-(thiazol/benzothiazol-2-yl)acetamides (1-18) were synthesized and evaluated for their inhibitory capacities on AR. 2-[(4-Amino-5-(4-methylphenyl)-4H-1,2,4-triazol-3-yl)thio]-N-(5-nitrothiazol-2-yl)acetamide (12) and 2-[(4-amino-5-(3-pyridyl)-4H-1,2,4-triazol-3-yl)thio]-N-(6-nitrobenzothiazol-2-yl)acetamide (17) were identified as the most effective AR inhibitors in this series with the K-i values of 0.04 +/- 0.01 mu M and 0.08 +/- 0.02 mu M, respectively as compared to quercetin (K-i = 5.66 +/- 0.66 mu M). These two compounds displayed competitive AR inhibition. MTT assay, a tetrazolium-based cell viability assay, was performed to determine the cytotoxic effects of compounds 1-18 on L929 mouse fibroblast (healthy) cell line. Compounds 1-18, except for compounds 10, 13, 14, 15 and 16, were found nontoxic against healthy cells. Besides, molecular docking studies were fundamentally in agreement with the biological data with regard to essential pi-pi interactions with Trp219, Phe122 and Trp111 residues in the active site of AR. Eventually, in vitro and in silico assays ascertain that in particular compounds 12 and 17 will attract a great notice as drug-like AR inhibitors for further investigations related to amelioration of long-term diabetic complications.

DFT computational insights into structural, electronic and spectroscopic parameters of 2-(2-Hydrazineyl)thiazole derivatives: a concise theoretical and experimental approach

It has been uncovered that compounds containing thiazole moiety display noteworthy biological properties, which have attracted the attention of many researchers in chemical biology as well as in medicinal chemistry. In the current examination, ten 2-(2-hydrazineyl)thiazole derivatives were studied using density functional theory (DFT). The geometry of all ten molecules was optimized by employing the DFT method with the B3LYP/6-311G (d,p) basis set. For the detailed structural and spectroscopic examination, the (E)-4-phenyl-2-(2-(1,2,6,7-tetrahydro-8H-indeno[5,4-b]furan-8-ylidene)hydrazineyl)thiazole (PIFHT) was studied as a representative molecule. The bond lengths and bond angles of thePIFHTmolecule were discussed for the detailed understanding of the structural entities. The electronic parameters of all ten molecules were analyzed by computing HOMO and LUMO pictures. Using frontier molecular orbital analysis, spectroscopic and quantum chemical parameters were evaluated and discussed to explore the chemical reactivity of the molecules. Besides, absorption energies, oscillator strength, and electronic transitions ofPIFHTmolecule were explored using time-dependent density-functional theory (TD-DFT) at the B3LYP/6-311G (d,p) level of theory in the gas phase, dichloromethane, and dimethyl sulfoxide solvents. The TD-DFT computed theoretical UV-Visible spectra of thePIFHTmolecule were compared with the experimental UV-Visible spectra. The scaled vibrational frequencies were compared with the experimental frequencies for the assignment of the vibrational bands. The comparisons between computed and experimental UV-Visible and IR spectral results are gratifying. The molecular electrostatic surface potential plots were computed for locating the reactivity sites. Mulliken atomic charges were also studied for acquiring insights into charge density.

Co(II) coordination polymers constructed from a bent chiral linker: influencing framework topology using co-ligands

A semi-rigid chiral ligand (1R, 2R)-4,4′-(trans-cyclohexane-1,2-diyl)bis(azanediyl)bis(carbonyl) dibenzoic acid (H(2)cbba) was combined with various Co(II) salts and dipyridyl co-ligands to obtain four 2D homochiral coordination polymers of composition [Co(cbba)(dipyridyl)]center dot solvate (dipyridyl = 4,4′-bipyridyl (bipy), bis(4-pyridyl)ethylene (bpe), 1,4-bis(4-pyridyl)benzene (1,4-bpb), 2,5-bis(4-pyridyl)thiazolo [5,4-d]thiazole (2,5-bptztz)) (1-4). The topology of the frameworks is mediated by the length of the co-ligands, with short dipyridyl co-ligands (4,4′-bipy and bpe) resulting in the formation of (4(13).6(2)) networks (1-2), while long co-ligands (1,4-bpb and 2,5-bptztz) led instead to (4(4).6(2)) (sql) networks that undergo 2D -> 2D parallel interpenetration to form a rare example of a homochiral polyrotaxane (3-4). The length of the dipyridyl co-ligand was also found to have an effect on the conformation of the flexible cbba(2-) ligands and the crystal packing of the networks.

Facile synthesis of spiro thiazolidinone via cyclic ketones, amines and thioglycolic acid by MCM-41-Schiff base-CuSO4 center dot 5H(2)O

Mesoporous MCM-41-supported Schiff base and CuSO(4)Greek ano teleia5H(2)O (MCM-41@Schiff base-CuSO(4)Greek ano teleia5H(2)O) catalyzed one-pot three-component condensation of cyclic ketones, amines and thioglycolic acid in toluene. And a series of corresponding spiro thiazolidinone derivatives were obtained in high yields (up to 97%). The synthesized catalyst was characterized via FT-IR, XRD, SEM, TEM and EDS and can be easily recovered by centrifugation and reused at 10 times without any change in catalytic activity. Moreover, the scale-up experiment also demonstrated the practicability of the catalytic system on the condensation. The possible mechanisms pave the way to investigation on the reactions of other cyclic ketones with thioglycolic acid.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 55981-09-4. Product Details of 55981-09-4.
