Synthesis of benzofuro[3,2-f]phthalazine derivatives

The reaction of hydrazine with dibenzofuran-1,2-dicarboxylic anhydrides followed by treatment with acetic acid resulted in the formation of 1,4-dioxo-1,2,3,4-tetrahydrobenzofuro[3,2-f]phthalazines. Dibenzofuran-1,2-dicarboxylic anhydrides were prepared by the Diels-Alder reaction of 2-alkenyl benzofurans and maleic anhydride followed by oxidative aromatization. Chlorination of 1,4-dioxo-1,2,3,4-tetrahydrobenzofuro[3,2-f]phthalazines and subsequent nucleophilic substitution afforded 1,4-dialkoxybenzofuro[3,2-f]phthalazines. These compounds were subjected to cytotoxicity assay against L1210 mice leukemia as analogues of methoxyellipticines.

Synthesis and SAR study of novel amidino 2-substituted benzimidazoles as potential antibacterial agents

A series of novel 2-substituted benzimidazole derivatives were synthesized and their antibacterial activity was assessed against selected Gram-positive and Gram-negative bacteria. The specific moiety at the 2-position of the benzimidazole was extensively modified with several fused heterocyclic functional groups containing nitrogen and sulfur heteroatoms. In addition, the influence of different amidino groups at the position 5 of benzimidazole scaffold was evaluated. The values of clogP (a partition coefficient) and clogD7.5 (calculated distribution coefficient, pH 7.5) were determined and the lipophilic character of compounds has been found to be important parameter for the observed activity of the tested benzimidazole derivatives against Moraxella catarrhalis. The indolo 2-substituted benzimidazole 13a demonstrated solid activity against Staphylococcus aureus (MICs 16 mug/mL) and Moraxella catarralis (MICs 2 mug/mL) and represents promising lead molecule for further optimization.

Synthesis, anticancer activity and molecular docking studies on a series of heterocyclic trans-cyanocombretastatin analogues as antitubulin agents

A series of heterocyclic combretastatin analogues have been synthesized and evaluated for their anticancer activity against a panel of 60 human cancer cell lines. The most potent compounds were two 3,4,5-trimethoxy phenyl analogues containing either an (Z)-indol-2-yl (8) or (Z)-benzo[b]furan-2-yl (12) moiety; these compounds exhibited GI50 values of <10 nM against 74% and 70%, respectively, of the human cancer cell lines in the 60-cell panel. Compounds 8, and 12 and two previously reported compounds in the same structural class, i.e. 29 and 31, also showed potent anti-leukemic activity against leukemia MV4-11 cell lines with LD50 values Combining double low line 44 nM, 47 nM, 18 nM, and 180 nM, respectively. From the NCI anti-cancer screening results and the data from the in vitro toxicity screening on cultured AML cells, seven compounds: 8, 12, 21, 23, 25, 29 and 31 were screened for their in vitro inhibitory activity on tubulin polymerization in MV4-11 AML cells; at 50 nM, 8 and 29 inhibited polymerization of tubulin by >50%. The binding modes of the three most active compounds (8, 12 and 29) to tubulin were also investigated utilizing molecular docking studies. All three molecules were observed to bind in the same hydrophobic pocket at the interface of ¡À-and 2-tubulin that is occupied by colchicine, and were stabilized by van der Waalsg? interactions with surrounding tubulin residues. The results from the tubulin polymerization and molecular docking studies indicate that compounds 8 and 29 are the most potent anti-leukemic compounds in this structural class, and are considered lead compounds for further development as anti-leukemic drugs.

Distribution and migration study of pesticides between peel and pulp in grape by online gel permeation chromatography-gas chromatography/mass spectrometry

A multi-residue method for the analysis of 175 pesticides was developed by online gel permeation chromatography-gas chromatography/mass spectrometry (GPC-GC/MS) to study pesticide distribution and migration between peel and pulp in grape. The separated peel and pulp samples were extracted by acetonitrile after fortified with chlorpyrifos-d10 isotope internal standard. The extract was first purified by solid phase distribution sorbent of primary secondary amine (PSA) and then detected by online GPC-GC/MS. At the spiking levels of 10, 50 and 200 mug kg-1, 73.7%, 94.3% and 98.9% of the pesticides, respectively, presented recoveries between 70% and 120%. The ratios were 91.4%, 94.9% and 92.0%, respectively, for the relative standard deviations (RSDs) bellow 15%. Limits of detection (LODs) for the pesticides in pulp were below 10 mug kg-1. Pesticides were separated to four groups according to the distribution ratios (peel/whole grape) of 100%, 80-99.9%, 50-80% and 0-50% in peel. Relationship between the pesticide distribution and corresponding regulation of EU maximum residue level (MRL) was discussed. Six factors influencing the pesticides distribution and migration between peel and pulp were discussed. Weak linear correlation between the pesticide solubility in water (20 C) and the distribution ratios (lowest and average) in peel was found for most of the detected pesticides with solubility less than 200 mg L-1.

Novel Terminal Bipheny-Based Diapophytoene Desaturases (CrtN) Inhibitors as Anti-MRSA/VISR/LRSA Agents with Reduced hERG Activity

CrtN has been identified as an attractive and druggable target for treating pigmented Staphylococcus aureus infections. More than 100 new compounds were synthesized, which target the overwhelming the defects of the CrtN inhibitor 1. Analogues 23a and 23b demonstrated a significant activity against pigmented S. aureus Newman and 13 MRSA strains (IC50 = 0.02-10.5 nM), along with lower hERG inhibition (IC50 > 30 muM, ?10-fold decrease in comparison with 1). Furthermore, 23a and 23b were confirmed to reduce the staphylococcal load in the kidney and heart in a mouse model with normal treatment deeper than pretreatment ones, comparable even with vancomycin and linezolid. Remarkably, 23a could strongly block the pigment biosynthesis of these nine multidrug-resistant MRSA strains, including excellent activity against LRSA strains and VISA strains in vivo, and all of which demonstrated that 23a has a huge potential against intractable MRSA, VISA, and LRSA issues as a therapeutic drug.

Synthesis of Enantioenriched Phthalide and Isoindolinone Derivatives from 2-Formylbenzoic Acid

Transformations of 2-formylbenzoic acid provide direct access to a series of heterocyclic organic compounds such as phthalides and isoindolinones. Here, we use (+)-cinchonine as a catalyst in conjunction with nonafluoro-tert-butanol as a hydrogen-bond donor to afford enantiomerically enriched acylated 3-hydroxyphthalides with up to 99% yield and 90% ee through dynamic kinetic resolution. Moreover, various 3-alkoxyphthalides as well as 2-alkyl-3-hydroxy-1-isoindolinones were synthesized from 2-formylbenzoic acid.

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.Product Details of 16859-59-9, you can also check out more blogs about16859-59-9
