Application of capillary electrophoresis technique for the enantioseparation of bioactive ferrocene-based compounds versus DFT calculated data

Herein, a series of bioactive ferrocene-modified N-heterocycles with alkyl linkers was prepared in good to quantitative yields starting from easy accessible ferrocene alcohols and heterocycles under acidic or neutral (for imidazole) conditions in racemic forms. The analytical resolution of a number of bioactive racemic ferrocene azoles 1-6 (where azole = imidazole, pyrazole, and benzotriazole derivatives) into enantiomers was first carried out by CE using sulfobuthylether-beta-CD (captisol) as a chiral selector. The analytical approaches to highly enantiomeric-enriched ferrocene derivatives are based on the formation of their inclusion complexes. The best chiral separation was achieved using zone CE in a quartz capillary. The ACE was used to evaluate the stability constants of captisol complexes with enantiomeric forms of two ferrocene derivatives 1, FcCHMe-imidazole, and 6, FcCHMe-benzotriazole. The optimal conditions for the resolution of the studied (R, S)-ferrocene compounds 1, 2, and 6 were predicted on the basis of the performed quantum chemical calculations and then implemented by the electrophoretic method. A high correlation between density functional theory calculation results and experimental electrophoresis data were obtained. Successful enantioseparation of racemic mixtures is of great importance for the characterization and further applications of drug candidates in enantiopure forms and in the development of clinical treatment. The advantages of the CE procedure make it possible to have important practical value and significance for determining the purity and enantiomeric excess of other ferrocene-containing compounds.

Functionalisation of Fe(3)O(4)nanoparticles by 2-((pyrazol-4-yl) methylene) hydrazinecarbothioamide enhances the apoptosis of human breast cancer MCF-7 cells

Cancer is a major cause of death. Thus, the incidence and mortality rate of cancer is globally important. Regarding vast problems caused by chemotherapy drugs, efforts have progressed to find new anti-cancer drugs. Pyrazole derivatives are known as components with anti-cancer properties. In here, Fe(3)O(4)nanoparticles were first functionalized with (3-chloropropyl) trimethoxysilane, then 2-((pyrazol-4-yl) methylene) hydrazinecarbothioamide (P) was anchored on the surface of magnetic nanoparticles (PL). The synthesized nano-compounds were characterized using Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, Zeta potential, dynamic light scattering, and energy-dispersive x-ray spectrometry analyses. The cytotoxicity effect was evaluated using MTT assay, apoptosis test by Flow cytometry, cell cycle analysis, Caspase-3 activity assay and Hoechst staining on MCF-7 cell line. The high toxicity for tumor cells and low toxicity on normal cells (MCF10A) was considered as an important feature (selectivity index, 10.9). Based on results, the IC50 for P and PL compounds were 157.80 and 131.84 mu M/ml respectively. Moreover, apoptosis inducing, nuclear fragmentation, Caspase 3 activity and induction of cell rest in sub-G1 and S phases, were also observed. The inhibitory effect of PL was significantly higher than P, which could be due to the high penetrability of Fe(3)O(4)nanoparticles.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 5932-27-4 help many people in the next few years. Formula: C6H8N2O2.

Design, synthesis, in silico, and in vitro evaluation of 3-phenylpyrazole acetamide derivatives as antimycobacterial agents

Mycobacterium tuberculosis (Mtb) is one of the most dangerous pathogens affecting immunocompetent and immunocompromised patients worldwide. Novel molecules, which are efficient and can reduce the duration of therapy against drug-resistant strains, are an urgent unmet need of the hour. In our current study, a series of new 2-(3-phenyl-1H-pyrazol-1-yl)acetamide and N ‘-benzylidene-2-(3-phenyl-1H-pyrazol-1-yl)acetohydrazide derivatives were designed, synthesized, and evaluated for their antimycobacterial potential. The biological evaluation revealed that 6b, 6m, 6l, 7a, and 7k exhibited selective and potent inhibitory activity against Mtb. Furthermore, compounds 6m and 7h were found to be nontoxic to Vero cells with CC50 of greater than 20 and 80 mg/ml, respectively, and exhibited promising selectivity indices (SI) of greater than 666 and 320, respectively. All derivatives exhibited excellent ADME (absorption, distribution, metabolism, and excretion) properties in silico. Also, all the derivatives were found compliant with Lipinski’s rule of five, showing their druggability profile. Molecular docking insights of these derivatives have shown outstanding binding energies on the mycobacterial membrane protein large transporters. These results indicate that this scaffold may lead to a potential antimycobacterial drug candidate in the discovery of antitubercular agents.

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 5932-27-4, in my other articles.

Exploring indole derivatives as myeloid cell leukaemia-1 (Mcl-1) inhibitors with multi-QSAR approach: a novel hope in anti-cancer drug discovery

In humans, the over-expression of Mcl-1 protein causes different cancers and it is also responsible for cancer resistance to different cytotoxic agents. Thus, discovery of potential inhibitors of Mcl-1 is very important and both the pharmaceutical industry and academia are looking at it in the quest for new anticancer drugs. In the present study, different molecular modelling techniques such as recursive partitioning, Bayesian classification, structural and physico-chemical interpretation analysis and pharmacophore mapping were employed in order to identify the crucial structural fingerprints important for the optimization of 143 indole derivatives as Mcl-1 inhibitors. These modelling studies emphasize that hydrophobic naphthyl rings, methyl-substituted 1H-pyrazole moiety, N(1)-tethered morpholinoethyl group, chloro substitutions at the 6th position of indole nucleusetc.are beneficial for Mcl-1 binding. Finally, statistically validated classical QSAR and machine learning-based models were also developed for screening and prediction of different indole derivatives as Mcl-1 inhibitors. The modelling analyses will help medicinal chemists to design potent Mcl-1 inhibitors in future. Thus, the present study was an attempt to speed up the anticancer drug discovery of indole-based Mcl-1 inhibitors.
