Three sets of antibacterial nitrofuran derivatives [set I, 5-R-substituted (Z)-2-(5-nitrofuran-2-ylmethylene)-3(2H)-benzofuranones (R = OCH3, H, CH3, C2H5, nC3H7, Cl, Br, CN, and NO2) and their 2-hydroxyphenyl and 2-acetoxyphenyl analogues; set TT, 5-R-substituted (E)-1-(2-hydroxyphenyl)-3-(5-nitrofuryl)-2-propen-1-ones (R = H, CH3, C2H5, Cl, and NO2); and set III, 5-R-substituted (E)-l-(2-acetoxyphenyl)-3-(5-nitrofuryl)-2-propen-l-ones (R = H, CH3; C2H5, Cl, and NO2)] were prepared and tested against a Gram-positive (Staphylococcus aureus, strain ATCC-25923) and a Gram-negative bacterium (Caulobacter crescentus, strain NA 1000). QSAR equations derived for the IC50 values against both bacteria show negative contributions of two terms: An electronic one, expressed either by sigma, the Hammett substituent constant, or by E, the cyclic voltametric reduction potential. Another term described by an indicator variable, Iabs, is assigned the value of 0 for set I compounds and the value of 1 for sets II and III. No important contribution of the hydrophobic factor was found. For the three sets, the QSAR regressions suggest that the same structural features describe the activities for both bacteria and that, although reduction is a necessary step, it should not be the determining one. These results agree with those found for the QSAR of 5-nitroimidazole analogues.

125-20-2, Name is Thymolphthalein, belongs to benzofurans compound, is a common compound. HPLC of Formula: C28H30O4In an article, once mentioned the new application about 125-20-2.

Herein, novel dicationic surfactants bearing morpholinium moieties in polar group, 14-s-14 Mor (s = 4, 6, 8, 10) are synthesized, and their aggregation behavior is studied and compared with reference surfactants, single-head morpholinium surfactant Mor-14, typical gemini with ammonium head group and dicationic surfactants with heterocyclic polar fragment. Geminis studied are found to exhibit superior solubilization capacity toward a pH indicator thymolphthalein and an inflammatory drug indomethacin, exceeding that of reference amphiphiles. The solubility of the probes is contributed by multifactor mechanism involving the solubilization in nonpolar core of micelles and periphery electrostatic interaction between micellar surface charge and ionic moieties of the drug. Mutual influence of the components occurs on their properties, including pKa shift of ionogenic groups of a guest molecule and decrease in critical micelle concentration of geminis.

S-CF3 bonds are important structural motifs in various pharmaceutical and agrochemical compounds. However, their preparation remains a major challenge in synthetic organic chemistry. Here, we report the development of a mild and fast photocatalytic trifluoromethylation of thiols. The combination of commercially available Ru(bpy)3Cl2, visible light and inexpensive CF3I gas proved to be an efficient method for the direct trifluoromethylation of thiols. The protocol is demonstrated on a wide range of aromatic, hetero-aromatic and aliphatic substrates in both batch and continuous microflow (32 examples, 52-98% yield). Process intensification through continuous microflow application resulted in a 15-fold increase in production rate (0.25 mmol min-1) due to improved gas-liquid mass transfer, enhanced irradiation as well as convenient handling of the gaseous CF3 source. Furthermore, the efficiency of the flow process allowed to reduce the amount of CF3I (1.1 equivalent) to reach full conversion. This journal is

The synthesis of novel 3-aryl-2-arylamidobenzofurans has been accomplished via a Curtius rearrangement strategy in four steps from benzofuran-2-carboxylic acids. The requisite Suzuki-Miyaura cross-coupling, with benzyl 3-bromobenzofuran-2-ylcarbamate or 2-arylamido-3-bromobenzofurans, revealed an unusual reductive debromination process due to the presence of the free NH group. This dehalogenation can be suppressed by N-alkylation. DMAP is an efficient reagent for the one-pot conversion of benzyl benzofuran-2-ylcarbamates into the corresponding benzofuran-2-arylamides through aroylation, thus acting both as an acyl transfer reagent and a deprotecting agent of the Cbz group. A mechanism is postulated.

Antagonists of 5HT3 receptors are clinically effective in treating nausea and emesis associated with certain oncolytic drugs, including cisplatin.Moreover, these agents may be useful in pharmacological management of several central nervous system disorders, including anxiety, schizophrenia, dementia, and substance abuse.Our studies on aroyltropanamides led to the discovery that dihydrobenzofuranyl esters and amides are potent 5HT3 receptor antagonists.Simple benzoyl derivatives of tropine and 3alpha-aminotropane possessed weak 5HT3 receptor antagonist activity, as judged by blockade of bradycardia produced by iv injection of serotonin (5HT) to anesthetized rats.Within this series, use of benzofuran-7-carboxamide as the aroyl moiety led to a substantial increase of 5HT3 receptor affinity.The optimal 5HT3 receptor antagonist identified via extensive SAR studies was endo-5-chloro-2,3-dihydro-2,2-dimethyl-N-(8-methyl-8-azabicyclo<3.2.1>oct-3-yl)-7-benzofurancarboxamide (Z)-2-butenedioate (zatosetron maleate).The 7-carbamyl regiochemistry, dimethyl substitution, chloro substituent, and endo stereochemistry were all crucial elements of the SAR.Zatosetron maleate was a potent antagonist of 5HT-induced bradycardia in rats (ED50=0.86 mug/kg iv).Low oral doses of zatosetron (30 mug/kg) produced long-lasting antagonism of 5HT3 receptors, as evidenced by blockade of 5HT-induced bradycardia for longer than 6 h in rats.Moreover, this compound did not produce hemodynamic effects after iv administration to rats, nor did it block carbamylcholine-induced bradycardia in doses that markedly blocked 5HT3 receptors.Thus, zatosetron is a potent, selective, orally effective 5HT3 receptor antagonist with a long duration of action in rats.

Allylic chlorides have been reduced to afford less substituted olefins by a low-valent chromium species in the presence of an alcoholic proton source. This process certainly has synthetic benefits since the regio-selectivity of the reduction is high and the reaction conditions are mild and nearly neutral.

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.Quality Control of 2-Methylbenzofuran, you can also check out more blogs about4265-25-2

Due to the emerging role of protein kinase CK2 as a molecule that participates not only in the development of some cancers but also in viral infections and inflammatory failures, small organic inhibitors of CK2, besides application in scientific research, may have therapeutic significance. In this paper, we present a new class of CK2 inhibitors-3-carboxy-4(1H)-quinolones. This class of inhibitors has been selected via receptor-based virtual screening of the Otava compound library. It was revealed that the most active compounds, 5,6,8-trichloro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid (7) (IC 50 = 0.3 muM) and 4-oxo-1,4-dihydrobenzo[h]quinoline-3-carboxylic acid (9) (IC50 = 1 muM), are ATP competitive (Ki values are 0.06 and 0.28 muM, respectively). Evaluation of the inhibitors on seven protein kinases shows considerable selectivity toward CK2. According to theoretical calculations and experimental data, a structural model describing the key features of 3-carboxy-4(1H)-quinolones responsible for tight binding to CK2 active site has been developed.
