Synthesis and biological evaluation of indole-2-carbohydrazides and thiazolidinyl-indole-2-carboxamides as potent tubulin polymerization inhibitors

A new series of N’-(substituted phenyl)-5-chloro/iodo-3-phenyl-1H-indole-2-carbohydrazide (5, 6) and N-[2-(substituted phenyl)-4-oxo-1,3-thiazolidin-3-yl]-5-iodo/chloro-3-phenyl-1H-indole-2-carboxamide (7, 8) derivatives were synthesized and evaluated for their anticancer properties. Compounds 5a and 6b, selected as prototypes by the National Cancer Institute for screening against the full panel of 60 human tumor cell lines at a minimum of five concentrations at 10-fold dilutions, demonstrated remarkable antiproliferative activity against leukemia, non-small cell lung cancer, colon cancer, central nervous system (CNS) cancer, melanoma, ovarian cancer, renal cancer, and breast cancer (MCF-7) cell lines with GI(50) values < 0.4 mu M. A subset of the compounds was then tested for their potential to inhibit tubulin polymerization. Compounds 6f and 6g showed significant cytotoxicity at the nM level on MCF-7 cells and exhibited significant inhibitory activity on tubulin assembly and colchicine binding at about the same level as combretastatin A-4. Finally, docking calculations were performed to identify the binding mode of these compounds. Group 5 and 6 compounds interacted with the colchicine binding site through hydrophobic interactions similar to those of colchicine. These compounds with antiproliferative activity at high nanomolar concentration can serve as scaffolds for the design of novel microtubule targeting agents.

2-(2-Methoxyphenyl)-3-((Piperidin-1-yl)ethyl)thiazolidin-4-One-Loaded Polymeric Nanocapsules: In Vitro Antiglioma Activity and In Vivo Toxicity Evaluation

Among gliomas types, glioblastoma is considered the most malignant and the worst form of primary brain tumor. It is characterized by high infiltration rate and great angiogenic capacity. The presence of an inflammatory microenvironment contributes to chemo/radioresistance, resulting in poor prognosis for patients. Recent data show that thiazolidinones have a wide range of pharmacological properties, including anti-inflammatory and antiglioma activities. Nanocapsules of biodegradable polymers become an alternative to cancer treatment since they provide targeted drug delivery and could overcome blood-brain barrier. Therefore, here we investigated the in vitro antiglioma activity and the potential in vivo toxicity of 2- (2-methoxyphenyl) -3- ((piperidin-1-yl) ethyl) thiazolidin-4-one-loaded polymeric nanocapsules (4L-N). Nanocapsules were prepared and characterized in terms of particle size, polydispersity index, zeta potential, pH, molecule content and encapsulation efficiency. Treatment with 4L-N selectively decreased human U138MG and rat C6 cell lines viability and proliferation, being even more efficient than the free-form molecule (4L). In addition, 4L-N did not promote toxicity to primary astrocytes. We further demonstrated that the treatment with sub-therapeutic dose of 4L-N did not alter weight, neither resulted in mortality, toxicity or peripheral damage to Wistar rats. Finally, 4L as well as 4L-N did not alter makers of oxidative damage, such as TBARS levels and total sulfhydryl content, and did not change antioxidant enzymes SOD and CAT activity in liver and brain of treated rats. Taken together, these data indicate that the nanoencapsulation of 4L has potentiated its antiglioma effect and does not cause in vivo toxicity. [GRAPHICS] .

Molecular structure and vibrational spectra of 2-(4-bromophenyl)-3-(4-hydroxyphenyl) 1,3-thiazolidin-4-one and its selenium analogue: Insights using HF and DFT methods

2-(4-Bromophenyl)-3-(4-hydroxyphenyl)-1,3-thiazolidin-4-one and its selenium analogue were studied in the gas phase using HF and DFT methods. The functionals considered were B3LYP, BP86 and M06. The basis set for all the atoms was 6-311++ G(d, p). Molecular parameters such as bond lengths, bond angles, rotational constants, dipole moments, electronic energies, and vibrational parameters namely harmonic vibrational frequencies and relative intensities were computed for these compounds. Atomization energies, HOMO-LUMO gaps and natural charges on the atoms were also calculated. The molecular parameters and the vibrational spectra of sulfur compound are in good agreement with the experimental data. Therefore, the data for the selenium analogue should be helpful in its future characterization.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 108-59-8 is helpful to your research. Product Details of 108-59-8.

Synthesis, Structural, and Theoretical Studies of Quinazoline-2,4-dione Derivatives

New quinazolin-2,4-dione derivatives have been synthesized and fully characterized. The new derivatives were synthesized using 3-(2-imino-4-oxo-3H,4H,5H-thiazolidin-3-yl)-1H-quinazolin-2,4-dione by nucleophilic addition mechanism. DFT calculations using B3LYP/6-311++G(d,p) level of the theory were used to investigate the molecular structures and the relative stabilities of the anticipated isomers (E and Z). Both experimental and theoretical calculations confirmed the higher stability of the Z-isomers compared to the E-isomers. The former is stabilized by two intramolecular hydrogen bonds compared to only one in the latter isomer. The frontier orbital calculations (HOMO and LUMO), and the energy gap confirmed the stability of the molecules.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 137-40-6, in my other articles.

Molecular Structure, FT-IR, NMR (C-13/H-1), UV-Vis Spectroscopy and DFT Calculations on (2Z, 5Z)-3-N(4-Methoxy phenyl)-2-N ‘(4-methoxy phenyl imino)-5-((E)-3-(2-nitrophenyl)allylidene) thiazolidin-4-one

In this study, some molecular properties of (2Z, 5Z)-3-N(4-methoxy phenyl)-2-N'(4-methoxy phenyl imino)-5-((E)-3-(2-nitrophenyl) allylidene) thiazolidin-4-one(MNTZ) are evaluated using a combination of spectroscopic characterization (FT-IR, H-1- and C-13 NMR chemical shifts) and theoretical calculations. Molecular geometry, vibrational wavenumbers, gauge-independent atomic orbital (GIAO), H-1 and C-13 chemical shift values and NBO analysis are investigated using B3LYP and PBE functionals with the 6-31G(d,p) basis set in the ground state. The calculated geometrical parameters and vibrational spectra are compared to available experimental data and each vibrational frequency is assigned on the basis of potential energy distribution (PED). The electronic transitions are calculated using time-dependent density functional theory (TDDFT). The energy band gap between the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energies are obtained by computing the frontier molecular orbitals using the B3LYP/6-31G(d,p) and PBE/6-31G(d,p) levels along with the global reactivity descriptors. Mulliken atomic charges and molecular electrostatic potential (MEP) are simulated using both functionals to find more reactive sites for electrophilic and nucleophilic attack. Finally, the thermodynamic functions (heat capacity, entropy, and enthalpy) from spectroscopic data are obtained and discussed in the range of 100-1000 K.

The present study assessed the biological potential of fourteen 1,3-thiazolidin-4-ones evaluating the antiglioma effect through decreasing of cell viability of glioblastoma multiform cells. The new compounds were efficient synthesized through multicomponent or multicomponent one-pot procedures in moderate to good yields (22-86%) from two arenealdehydes (4-(methylthio)benzaldehyde and 4(methylsulfonyl)benzaldehyde), seven amines (aromatic and aliphatic) and mercaptoacetic acid. The compounds were identified and characterized by GC/MS and NMR, five of them by HRMS. Six thiazoli-dinones showed significant effect of decreasing cell viability compared to standard drug TMZ at 100 mu M in 72 h in C6 cell line by MTT assay. The compounds 5b, 5e, 5g and 6e showed the best results in the screening at 100 AM and were analyzed at different concentrations (5, 25, 50, 100 and 250 mu M). Compounds 5b and 5e showed statistical difference at 5 mu M, 6e at 25 mu M and 5g at 50 mu M in 72 h of treatment. The cytotoxicity study in primary astrocytes cells was evaluated and none of fourteen compounds showed toxicity at 100 mu M, eight of them were not cytotoxic at 250 mu M, both in 72 h. In addition, the propidium iodide assay demonstrated that the compounds might induce cell death by necrosis. In conclusion, this work reports at least four compounds (5b, 5e, 5g and 6e) with potential anti-tumor effect against glioblastoma multiform cell presenting activity at low concentrations and safe profile of cytotoxicity.

Preparation of some novel thiazolidinones, imidazolinones, and azetidinone bearing pyridine and pyrimidine moieties with antimicrobial activity

By aiming to design new antimicrobial agents, we prepared new series of thiazolidin-4-ones(12a-d), imidazolin-4-ones(13a-d), and azetidin-2-ones (14a-d), having pyridine and pyrimidine moieties. Chemical structures of these derivatives were elucidated by the use of spectral and elemental analyses. All the new substituted pyridopyrimidines were subjected to in vitro antimicrobial testing by estimating the zone of inhibition toward Bacillus subtilis and Staphylococcus aureus, as examples of bacterial species, in addition to Aspergillus flavus and Candida albicans, as examples of fungal species. The results of antimicrobial testing detected that all the screened derivatives displayed antibacterial effect; especially azetidin-2-one derivative, (14c), was the most active one. Regarding the antifungal potential, only thiazolidinone derivatives, 12a and 12c, and the imidazolinone, 13c, displayed inhibitory activity toward Aspergillus flavus, while all the tested compounds, 12a-d, 13a-d, and 14a-d, except 14a, produced inhibitory potential toward Candida albicans. Docking studies of the most active antimicrobial agents, 12c, 13c, and 14c, within GLN-6-P, recorded good scores with several binding interactions with the active site.
