The article conveys some information:

A diverse series of 1,2,4-oxadiazoles, e.g., I was designed, synthesized and evaluated as anticancer agents targeting carbonic anhydrase IX (CAIX). Initial structure-activity anal. suggested that the thiazole/thiophene-sulfonamide conjugates of 1,2,4-oxadiazoles exhibited potent anticancer activities with low μM potencies. 4-Methyl-N-(2-(3-phenyl-1,2,4-oxadiazol-5-yl)thiophen-3yl)benzenesulfonamide exhibited antiproliferative activity (IC50 = 11.1μM) along with appreciable inhibition potential for tumor-associated CAIX (IC50 = 4.23μM) isoform. Therefore, it was structurally optimized and its SAR oriented derivatives II [R1 = Me, Ph, 4-FC6H4, etc.; R2 = Me, Ph] were synthesized and evaluated. This iteration resulted in compound II [R1 = 4-H2NC6H4, R2 = Ph] with an almost two-fold increase in antiproliferative effect (IC50 = 6.0μM) comparable to the clin. drug doxorubicin and significantly higher potency against CAIX (IC50 = 0.74μM). Addnl., compound II [R1 = 4-H2NC6H4, R2 = Ph] treatment decreased the expression of CAIX, induced apoptosis and ROS production, inhibited colony formation and migration of colon cancer cells. The experimental process involved the reaction of Methyl 4-fluoro-3-nitrobenzoate(cas: 329-59-9Computed Properties of C8H6FNO4)

Methyl 4-fluoro-3-nitrobenzoate(cas: 329-59-9) belongs to methyl benzoate. Methyl benzoate reacts at both the ring and the ester, depending on the substrate. Electrophiles attack the ring, illustrated by acid-catalysed nitration with nitric acid to give methyl 3-nitrobenzoate.Computed Properties of C8H6FNO4

Study of the Activity as Inhibitors of Amyloid-β Aggregation and Neurotoxicity Evaluation》.Inorganic Chemistry published the findings.Recommanded Product: 329-59-9 The information in the text is summarized as follows:

The design of small mols. that can target the aggregation of Aβ as potential therapeutic agents for Alzheimer’s disease is an area of study that has attracted a lot of attention recently. The novel ligand Me 1-butyl-2-pyridyl-benzimidazole carboxylate was prepared for the synthesis of a series of new iridium(III), ruthenium(II), and platinum(II) 2-pyridyl-benzimidazole complexes. The crystal structure of the half-sandwich iridium(III) complex was established by X-ray diffraction. An arrangement of two cationic complexes in the unit cell is observed, and it seems to be organized by weak π···π interactions that are taking place between two symmetry-related benzimidazole ring systems. All new compounds inhibited aggregation of Aβ1-42 in vitro as shown by both thioflavin T fluorescence assay and transmission electron microscopy. Among them the Ir compound rescued the toxicity of Aβ1-42 in primary cortical neurons effectively. The results came from multiple reactions, including the reaction of Methyl 4-fluoro-3-nitrobenzoate(cas: 329-59-9Recommanded Product: 329-59-9)

C.; Papadimitriou, Stathys; Kennedy, Hilary; Mowlem, Matthew C.; Dickson, Andrew G.; Gledhill, Martha; Achterberg, Eric P. published 《Characterization of meta-Cresol Purple for spectrophotometric pH measurements in saline and hypersaline media at sub-zero temperatures》.Scientific Reports published the findings.Formula: C8H6FNO4 The information in the text is summarized as follows:

Accurate pH measurements in polar waters and sea ice brines require pH indicator dyes characterized at near-zero and below-zero temperatures and high salinities. We present exptl. determined phys. and chem. characteristics of purified meta-Cresol Purple (mCP) pH indicator dye suitable for pH measurements in seawater and conservative seawater-derived brines at salinities (S) between 35 and 100 and temperatures (T) between their f.p. and 298.15 K (25°C). Within this temperature and salinity range, using purified mCP and a novel thermostated spectrophotometric device, the pH on the total scale (pHT) can be calculated from direct measurements of the absorbance ratio R of the dye in natural samples aspHT = – log(kT2e2) + log(((R – e1)/(1 – R(e3/e2)))) Based on the mCP characterization in these extended conditions, the temperature and salinity dependence of the molar absorptivity ratios and – log(kT2e2) of purified mCP is described by the following functions: e1 = -0.004363 + 3.598 × 10-5T, e3/e2 = -0.016224 + 2.42851 × 10-4T + 5.05663 × 10-5(S – 35), and – log(kT2e2) = -319.8369 + 0.688159 S -0.00018374 S2 + (10508.724 – 32.9599 S + 0.059082S2) T-1 + (55.54253 – 0.101639 S) ln T -0.08112151T. This work takes the characterization of mCP beyond the currently available ranges of 278.15 K = T = 308.15 K and 20 = S = 40 in natural seawater, thereby allowing high quality pHT measurements in polar systems.Methyl 4-fluoro-3-nitrobenzoate(cas: 329-59-9Formula: C8H6FNO4) was used in this study.

《Benzimidazole derivatives as potent and isoform selective tumor-associated carbonic anhydrase IX/XII inhibitors》 was published in Bioorganic Chemistry in 2020.

Quality Control of Methyl 4-fluoro-3-nitrobenzoate The article mentions the following:

We describe the synthesis of a series of 2-arylbenzimidazole derivatives bearing sulfonamide functionality (4a-d, 7a-c and 10) as well as hydroxamic acid (15a-b), carboxylic acid (16a-b), carboxamide (17a-b) and boronic acid (22a-b and 26) functionalities, which act as human carbonic anhydrase (hCA, EC 4.2.1.1) inhibitors. The newly synthesized benzimidazole derivatives were evaluated against 4 physiol. relevant CA isoforms (hCA I, II, IX, and XII), and especially the sulfonamide-containing benzimidazoles demonstrated intriguing inhibitory activity against tumor associated CA IX and XII with KI values in the range of 5.2-29.3 nM and 9.9-41.7 nM, resp. Notably, compound 4c was the most potent and selective CA IX (KI = 6.6 nM) and XII (KI = 9.9 nM) inhibitor with a significant selectivity ratio over cytosolic CA I and II isoforms in the range of 3.4-25.2. In addition, compounds having hydroxamic acid (15a-b) or carboxylic acid (16a-b) functionalities resulted in greater selectivity ratios for CA IX/XII over CAI/II in the range of 4.1-121.5 although with KI values in lower micromolar potency (KIs = 0.36-0.85μM for CA IX/XII).

Tuberculosis (TB) is a devastating disease that claims millions of lives every year. Hindered access or non-compliance to medication, especially in developing countries, led to drug resistance, further aggravating the situation. With current standard therapies in use for over 50 years and only few new candidates in clin. trials, there is an urgent call for new TB drugs. A powerful tool for the development of new medication is structure-guided design, combined with virtual screening or docking studies. Here, we report the results of a drug-design project, which we based on a publication that claimed the structure-guided discovery of several promising and highly active inhibitors targeting the secreted chorismate mutase (*MtCM) from Mycobacterium tuberculosis. We set out to further improve on these compounds and synthesized a series of new derivatives Thorough evaluation of these mols. in enzymic assays revealed, to our dismay, that neither the claimed lead compounds, nor any of the synthesized derivatives, show any inhibitory effects against *MtCM.

Ultrasound-assisted synthesis of benzimidazo[2,1-b]quinazolin-1(1H)-ones was achieved via piperidine-catalyzed three-component reaction of 2-aminobenzimidazoles, an aromatic aldehyde, and 1,3-dione in aqueous isopropanol. This mechanism was first suspected following our identification of unusual reaction intermediates in a one-pot reaction. An unprecedented coupling reaction, it involved a nucleophilic attack by 2-aminobenzimidazole on in situ generated Michael adduct, followed by electrocyclic ring formation reaction. In contrast to the commonly accepted mechanism, that the direct reaction of 2-amino benzimidazole with a Knoevenagel adduct cannot deliver target compounds In the part of experimental materials, we found many familiar compounds, such as Methyl 4-fluoro-3-nitrobenzoate(cas: 329-59-9Safety of Methyl 4-fluoro-3-nitrobenzoate)
