2-Amino-5-(cyanomethylsulfanyl)-1H-pyrroles from Propargylamines, Isothiocyanates, and Bromoacetonitrile by One-Pot Synthetic Protocol

Tertiary propargylamines (such as N,N-dialkylpropargylamines, N-propargylpyrrolidine, -piperidine, and -morpholine), isothiocyanates, and bromoacetonitrile have been shown to be readily available building blocks for the highly selective one-pot construction of rare-functionalized pyrroles, namely so far inaccessible 1-substituted 2-amino-5-(cyanomethylsulfanyl)-1H-pyrroles, in up to 92 % yield. This highly efficient and operationally simple approach includes the initial formation of lithium but-2-ynimidothioate (adduct of monolithiated propargylamine and isothiocyanate), its transformation into potassium buta-2,3-dienimidothioate under the action of the t-BuOK/DMSO system (through acetylene-allene isomerization and the exchange by cations), intramolecular cyclization into potassium thienylamide (at <= 15 degrees C), followed by its re-cyclization into potassium pyrrolylsulfide at a higher temperature (45-60 degrees C), and the final S-alkylation of the latter with bromoacetonitrile. The total reaction time is 45-60 min. Synthetic Route of 10310-21-1, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 10310-21-1 is helpful to your research.

Dereplication Analysis and Antitrypanosomal Potential of the Red Sea Sponge Amphimedon sp. Supported by Molecular Modelling

The present investigation was oriented to the discovery of chemical compounds from the Red Sea spongeAmphimedonsp., as a source of active agents againstTrypanosoma brucei, the causal agent of human sleeping sickness. Dereplication analysis of the active fraction fromAmphimedonsp. using liquid chromatography coupled with high-resolution mass spectrometry revealed the chemical richness of this sponge with diverse alkaloidal classes such as purine, manzamine, bis-piperidine, and pyridine. Activity-guided fractionation of the total extract showed the antitrypanosomal activity concentrated in the ethyl acetate fraction (IC50 = 3.8 mu g/ml).In silicomodelling was carried out on the dereplicated compounds to provide an insight into their antitrypanosomal mechanism of action with docking study on eight trypanosomal proteins. Molecular dynamics was run for the complex of zamamidine D and ornithine decarboxylase, which illustrated that zamamidine D has the highest affinity to the ornithine decarboxylase enzyme. These results highlight the valuable chemical profile ofAmphimedonsp., as a lead source for antitrypanosomal natural products.

2-Indolinone Derivatives as Potent Urease Inhibitors

Background: 2-Indolinone is a bicycle, heterocyclic compound analogous of indole skeleton containing a carbonyl group at 2-position of the 5-membered ring. Recently, different biological evaluations of oxindole derivatives have been reported. A variety of compounds with oxindoles moiety exhibit useful pharmaceutical properties like anti-inflammatory, anti-bacterial, anticancer, anti-proliferative, anti-hypertensive, anti-HIV and anti-convulsant activities. Methods: In the present study, fifteen 6-chloro-3-oxindole derivatives (1-15) were screened for urease inhibitory activity. The binding mode of the synthesized compounds was studied by molecular docking and found good results. 6-Chloro-3-oxindole derivatives 1-15 were synthesized from 6-chlorooxindole by refluxing with different aromatic aldehydes in ethanol in the presence of piperidine in high yields. Docking was carry out of the ligands into HCV NS3/4A protein. The software package MOE (Molecular Operating Environment) was used for docking. Results: Our present study has shown that compound 6 (IC50 = 13.34 +/- 1.75 mu M), 2 (IC50 = 16.67 +/- 1.73 mu M), and 5 (IC50 = 17.85 +/- 2.21 mu M) were found to be the most potent urease inhibitors as compared to the standard thiourea (IC50 = 21.1 +/- 0.11 mu M). Conclusion: Our present study has shown that Compounds 6 (IC50 = 13.34 +/- 1.75 mu M), 2 (IC50 = 16.67 +/- 1.73 mu M), and 5 (IC50 = 17.85 +/- 2.21 mu M) were found to be the most potent urease inhibitors as compared to the standard thiourea (IC50 = 21.1 +/- 0.11 mu M). These may serve as lead compounds for better urease inhibitors after fine tuning in the structure and further studies in future.

Multistage antiplasmodial activity of hydroxyethylamine compounds,in vitroandin vivoevaluations

Malaria, a global threat to the human population, remains a challenge partly due to the fast-growing drug-resistant strains ofPlasmodiumspecies. New therapeutics acting against the pathogenic asexual and sexual stages, including liver-stage malarial infection, have now attained more attention in achieving malaria eradication efforts. In this paper, two previously identified potent antiplasmodial hydroxyethylamine (HEA) compounds were investigated for their activity against the malaria parasite’s multiple life stages. The compounds exhibited notable activity against the artemisinin-resistant strain ofP. falciparumblood-stage culture with 50% inhibitory concentrations (IC50) in the low micromolar range. The compounds’ cytotoxicity on HEK293, HepG2 and Huh-7 cells exhibited selective killing activity with IC(50)values > 170 mu M. Thein vivoefficacy was studied in mice infected withP. bergheiNK65, which showed a significant reduction in the blood parasite load. Notably, the compounds were active against liver-stage infection, mainly compound1with an IC(50)value of 1.89 mu M. Mice infected withP. bergheisporozoites treated with compound1at 50 mg kg(-1)dose had markedly reduced liver stage infection. Moreover, both compounds prevented ookinete maturation and affected the developmental progression of gametocytes. Further, systematicin silicostudies suggested both the compounds have a high affinity towards plasmepsin II with favorable pharmacological properties. Overall, the findings demonstrated that HEA and piperidine possessing compounds have immense potential in treating malarial infection by acting as multistage inhibitors.

Chlorination of 2-substituted 1-hydroxyindoles

Chlorination of 1-hydroxyindole-5,6-dicarbonitriles and 1-hydroxypyrrolo[3,4-f]indole-5,7(1H,6H)-diones with N-chlorosuccinimide afforded previously unknown 3,3-dichloro-3Hindole 1-oxides instead of the expected 3-chloro-1-hydroxyindoles. The latter, however, were prepared in good yields by treatment of the above 3,3-dichloro-3H-indole 1-oxides with piperidine in ethanol. Reduction of 3,3-dichloro-5,6-dicyano-3H-indole 1-oxides with Zn in AcOH yielded the corresponding 3-chloroindole-5,6-dicarbonitriles.

Characterization of reactive intermediates formation in dacomitinib metabolism and bioactivation pathways elucidation by LC-MS/MS: in vitro phase I metabolic investigation

Dacomitinib (DCB) is a second generation irreversible tyrosine kinase inhibitor (TKI) that is claimed to overcome the disadvantages of the resistance developed by the first line epidermal growth factor receptor (EGFR) TKIs. In the current study, metabolites of phase I for DCB were systematically explored. DCB reactive metabolites were also investigated in rat liver microsomes in presence of potassium cyanide or methoxylamine that were employed as capturing agents for iminium reactive intermediates and aldehyde, respectively, to form stable complexes which can be detected by LC-MS/MS. As a result, four in vitro phase I metabolites were observed with major pathway of piperidine ring hydroxylation. Additionally, two potentially reactive intermediates, one aldehyde and one iminium ions were characterized. Two different pathways of bioactivation were ultimately proposed.
