The resurgence of tuberculosis and the emergence of multidrug-resistant strains of Mycobacteria drugs has propelled the development of new structural classes of antitubercular agents. The present study was undertaken to investigate the opportunities which the enzyme dihydrofolate reductase, a promising drug target for treatment of Mycobacterial infections offers for the development of new TB drugs. Pharmacophore models were established by using the HipHop and HypoGen algorithms implemented in the Catalyst software package. The best quant. pharmacophore model, consisted of two hydrogen bond acceptor, a hydrophobic aliphatic and a ring aromatic feature which has the highest correlation coefficient (0.93), as well as enrichment factor of 1.75 and Goodness of hit score of 0.73. Based on the pharmacophore model some leads were optimized and some of its derivatives were synthesized and analyzed by following QSAR studies. About 25 compounds of substituted benzothiazole/benzimidazole derivatives were synthesized as potent DHFR inhibitors and screened for antimycobacterial activity. To further explore the structure-activity relationships of all newly synthesized compounds, 3D-QSAR analyses were developed. MFA studies were performed with the QSAR module of Cerius2 using genetic partial least squares (G/PLS) algorithm. The predictive ability of the developed model was assessed using a training set of 25 and a test set of 5 compounds (r2pred = 0.924). The analyzed MFA model demonstrated a good fit, having r2 value of 0.868 and cross validated coefficient r2cv value of 0.771. In the experiment, the researchers used many compounds, for example, 7-Methyl-1H-benzo[d]imidazole (cas: 4887-83-6Safety of 7-Methyl-1H-benzo[d]imidazole).

And the article was included in Journal of Molecular Liquids in 2016.Formula: C11H20N2 This article mentions the following:

A series of 1,3-dialkylimidazolium tetrafluoroborate salts had been prepared via one-step alkylation of N-alkylimidazole with trialkyloxonium salts and traditional two-step method, resp. The possible impurities in these ionic liquids (ILs) such as Cl^–, Br^–, Na⁺ and alkyl imidazoles were measured. Detailed characterizations of two approaches in the ILs properties and performances such as spectroscopic properties, phase behavior, viscosity, refractive index, and electrochem. properties were systemically conducted. The obtained results showed that the variety of synthesized methods resulted in the distinct changes in physicochem. properties for the same IL. Therein, the comparison of spectroscopic properties and phase behaviors for the employed ILs were emphasized. Furthermore, in most cases, the ILs prepared by traditional two-step possessed the higher viscosity, lower refractive index as well as lower ionic conductivity than that of ILs prepared by one-step. It was worth noting that the 1-decyl-3-ethylimidazolium tetrafluoroborate ([DEIm]BF₄) prepared with the traditional and trialkyloxonium methods resp. exhibited distinctly different phase and fluorescence behaviors. The reason might be attributed to the significant improvement on the purities of ILs by the one-step strategy.

Does the rising placebo response impact antihypertensive clinical trial outcomes? An analysis of data from the Food and Drug Administration 1990-2016 was written by Khan, Arif;Mar, Kaysee Fahl;Schilling, Joshua;Brown, Walter A.. And the article was included in PLoS One in 2018.Reference of 145040-37-5 This article mentions the following:

Background Recent studies show that placebo response has grown significantly over time in clin. trials for antidepressants, ADHD medications, antiepileptics, and antidiabetics. Contrary to expectations, trial outcome measures and success rates have not been impacted. This study aimed to see if this trend of increasing placebo response and stable efficacy outcome measures is unique to the conditions previously studied or if it occurs in trials for conditions with physiol.-measured symptoms, such as hypertension. Method For this reason, we evaluated the efficacy data reported in the US Food and Drug Administration Medical and Statistical reviews for 23 antihypertensive programs (32,022 patients, 63 trials, 142 treatment arms). Placebo and medication response, effect sizes, and drug-placebo differences were calculated for each treatment arm and examined over time using meta-regression. We also explored the relationship of sample size, trial duration, baseline blood pressure, and number of treatment arms to placebo/drug response and efficacy outcome measures. Results Like trials of other conditions, placebo response has risen significantly over time (R² = 0.093, p = 0.018) and effect size (R² = 0.013, p = 0.187) drug-placebo difference (R² = 0.013, p = 0.182) and success rate (134/142, 94.4%) have remained unaffected, likely due to a significant compensatory increase in antihypertensive response (R² = 0.086, p<0.001). Treatment arms are likely overpowered with sample sizes increasing over time (R² = 0.387, p<0.0001) and stable, large effect sizes (0.78 -0.37). The exploratory anal. of sample size, trial duration, baseline blood pressure, and number of treatment arms yielded mixed results unlikely to explain the pattern of placebo response and efficacy outcomes over time. The magnitude of placebo response had no relationship to effect size (p = 0.877), antihypertensive- placebo differences (p = 0.752), or p-values (p = 0.963) but was correlated with antihypertensive response (R² = 0.347, p<0.0001). Conclusions As hypothesized, this study shows that placebo response is increasing in clin. trials for hypertension without any evidence of this increase impacting trial outcomes. Attempting to control placebo response in clin. trials for hypertension may not be necessary for successful efficacy outcomes. In exploratory anal., we noted that despite finding significant relationships, none of the trial or patient characteristics we examined offered a clear explanation of the rise in placebo and stability in outcome measures over time. Collectively, these data suggest that the phenomenon of increasing placebo response and stable efficacy outcomes may be a general trend, occurring across trials for various psychiatric and medical conditions with physiol. and non-physiol. endpoints. In the experiment, the researchers used many compounds, for example, 1-(((Cyclohexyloxy)carbonyl)oxy)ethyl 1-((2′-(2H-tetrazol-5-yl)-[1,1′-biphenyl]-4-yl)methyl)-2-ethoxy-1H-benzo[d]imidazole-7-carboxylate (cas: 145040-37-5Reference of 145040-37-5).

The novel imidazolium salts based on bis(2-ethylhexyl) sulfosuccinate anion have been developed as ionic liquids (ILs) which can potentially be used as absorbents of acid gases. The transport of CO₂, H₂S, CH₄ and N₂ in a series of supported ionic liquid membranes (SILMs) with immobilized conventional (bmim[PF₆], bmim[BF₄], bmim[Tf₂N]) and novel ILs was investigated. The supported ionic liquid membrane containing 1-butyl-3-methylimidazolium bis(2-ethylhexyl) sulfosuccinate (bmim[doc]) yielded a very high H₂S solubility and, hence, H₂S/N₂ selectivity equal to 65. However, the permeability of acid gases through such a membrane had relatively low values varying in a range of 100-200 Barrer, whereas permeability for SILMs impregnated by conventional ILs achieved 565 Barrer. The most effective separation of CO₂ was observed for SILMs impregnated by bmim[BF₄] predominantly owing to solubility component of permeability. In order to estimate the stability of SILMs, the polymeric support surface properties such as free surface energy, surface topol. and roughness parameters were evaluated. Anal. of exptl. data revealed that among the tested ILs, bmim[BF₄] immobilized in porous polymeric support was more resistant to losses and determined the higher stability of membranes.

Anisotropic ionic conductivity in fluorinated ionic liquid crystals suitable for optoelectronic applications was written by Abate, Antonio;Petrozza, Annamaria;Cavallo, Gabriella;Lanzani, Guglielmo;Matteucci, Francesco;Bruce, Duncan W.;Houbenov, Nikolay;Metrangolo, Pierangelo;Resnati, Giuseppe. And the article was included in Journal of Materials Chemistry A: Materials for Energy and Sustainability in 2013.Computed Properties of C11H20N2 This article mentions the following:

The authors report a library of thirteen fluorinated ionic liquids consisting of iodide salts of 1-alkyl-3-polyfluoroalkyl-imidazolium cations. By changing the length of the alkyl and polyfluoroalkyl pendants, particular combinations of these result in compounds showing a mesophase. The nature and the mol. arrangement of the mesophase are characterized by polarized optical microscopy and powder x-ray diffraction anal., among others. After the addition of I₂ to generate the I^–/I₃^– redox couple, anisotropic ionic conductivity takes place along preferential pathways in the lamellar structure of the mesophase. Notably, the addition of I₂ does not suppress the mesophase temperature range, contrary to previously reported systems. Also, the tendency of these materials to supercool allows the mol. arrangement in the mesophase to be retained in a solid film at ambient temperatures Finally, the authors demonstrate their applicability as a quasi-solid electrolyte by preparing dye-sensitized solar cells with power conversion efficiencies comparable to the previous reports. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Computed Properties of C11H20N2).

Benzotriazole and related compounds as corrosion inhibitors for copper was written by Cotton, Joseph B.;Scholes, Ian R.. And the article was included in British Corrosion Journal in 1967.Reference of 4887-83-6 This article mentions the following:

With reference to the corrosion inhibition of Cu by benzotriazole and analogous compounds reacted with Cu+ and Cu2+ ions. Recent data and practical operational experience are detailed. Related compounds included those where 1 or 2 of the N atoms of benzotriazole are substituted by C or the labile H atom is replaced by a CH3 group, i.e. indazole, benzimidazole, indole, and methyl benzotriazole. Salt-spray testing showed only benzotriazole and indazole prevented staining and only the former retained tarnish-resistant properties after the treated Cu surface was washed with organic solvents; the N-H group and one another N atoms and an insoluble complex formation appear necessary. Substitutional studies in the benzene ring showed Cl or nitro-groups in the 5-position increased acidity of the labile H atom but did not affect inhibition effects; naphthotriazole behaved similarly but 5-hydroxy indazole and 4-methyl benzimidazole were less effective than the parent compounds Generally 5-membered heterocyclics, imidozole, 1,2,4-triazole, and pyrazole and their derivatives showed little inhibitive effect. The benzotriazole-CuCl2 reaction product had a metal-organic ratio of 1 atom Cu: 1 mol. of benzotriazole; it was diamagnetic, amorphous, or microcrystalline, probably with a basic formula C6H4N3Cu. Reaction with CuCl2 did not give a 2:1 benzotriazole:Cu ratio and the product had excess Cu, chloride and H2O. The surface film apparently forms a true metal surface bond and the complex is polymeric.
