Design and Biological Evaluation of Furan/Pyrrole/Thiophene-2-carboxamide Derivatives as Efficient DNA GyraseB Inhibitors of Staphylococcus aureus

DNA topoisomerases are well-validated targets in micro-organisms. DNA gyraseB is one of the most important enzymes among them as per their clinical importance. In earlier study, a novel lead 4-((4-(furan-2-carboxamido)phenyl)amino)-4-oxobutanoic acid was identified as inhibitor against DNA gyraseB with an IC50 of 12.88 ¡À 1.39 mum. Subsequently, analogues of this lead were developed and evaluated through in vitro assays and in vivo studies. Among the 24 analogues, compound 22 was found to be the top hit with an improved DNA gyraseB activity of 5.35 ¡À 0.61 mum, and the binding affinity of this compound was further ascertained biophysically through differential scanning fluorimetry. The most potent ligand did not show any signs of cardiotoxicity in zebra fish ether-ago-go-related gene, ascertaining the safety profile of this series a breakthrough among the previously reported cardiotoxic gyraseB inhibitors.

Production of 1,5-pentanediol from biomass via furfural and tetrahydrofurfuryl alcohol

Production of 1,5-pentanediol from tetrahydrofurfuryl alcohol, which can be produced from biomass via furfural, is reviewed. Silica- or carbon-supported rhodium catalysts modified with Re, Mo or W show high activity and selectivity, while commercial hydrogenation catalysts such as Ru/C, copper chromite and Raney Ni show much lower activity and selectivity. The formation of metal bond between rhodium metal particles and additive metal is a key to the high performance. The reaction mechanism is discussed based on the characterization data, reactivity of related substrates and kinetics.

Direct Calpha-heteroarylation of structurally diverse ethers: Via a mild N -hydroxysuccinimide mediated cross-dehydrogenative coupling reaction

An important challenge in the Calpha-heteroarylation of ethers is the requirement of a large excess amount of ethers (that are used as solvents in many cases) to achieve effective transformations. This drawback has significantly restricted the Calpha-heteroarylation of ethers to the use of simple and easily accessible ether substrates. To overcome this limitation, a new, efficient, N-hydroxysuccinimide (NHS) mediated, mild and metal-free CDC strategy for the direct Calpha-heteroarylation of diverse ethers has been developed. Different to our previous benzaldehyde mediated photoredox Calpha-heteroarylation, we have identified NHS as a new and efficient mediator without using light. A distinct non-photoredox engaged hydrogen-atom-transfer (HAT) mechanism that used a nitrogen-centered radical cation produced from NHS is initially revealed. Notably, only 5-10 equivalents of ethers as coupling partners are used, which allows for structurally diverse and complex ethers to engage in this process, to create highly medicinally relevant Calpha-heteroarylated ethers. Furthermore, more structurally diverse heterocyclics can serve as reactants for this process.

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.name: Tetrahydrofurfuryl Acetate, you can also check out more blogs about637-64-9

Synthesis of simple analogues of methyllycaconitine – An efficient method for the preparation of the N-substituted anthranilate pharmacophore

The synthesis of several A and AE ring analogues of the alkaloid methyllycaconitine is reported. The key 2-(2?-methylsuccinimido)benzoate ester pharmacophore is introduced using an efficient two step procedure. Esterification of the alcohol precursors with N-(trifluoroacetyl)anthranilic acid under Steglich conditions followed by sodium borohydride mediated cleavage of the trifluoroacetyl group affords the anthranilate esters. Subsequent fusion with methylsuccinic anhydride affords the N-substituted anthranilate derivatives containing the key pharmacophore present in a range of commonly occurring Delphinium and Aconitum alkaloids.

More particularly, the present invention relates to an anticancer agents containing, as an active ingredient, at least one compound selected from the group consisting of omega-hydroxy fatty acids and salts or esters thereof, hydroxy oxo-fatty acids and salts or esters thereof, lactones, macrocyclic ketones, and macrocyclic diesters having specific chemical structures. With respect to the compounds described above used in the present invention, since the activities of killing cancer and inhibiting cancer metastasis are significantly high, the effects of preventing the recurrence of cancer and preventing cancer are exhibited, the cytotoxicity is significantly low, and a small dose is effective, it is possible to provide anticancer agents having significantly decreased side effects. Additionally, use in combination with known antitumor agents can further enhance the activity of inhibiting cancer metastasis. Among the anticancer agents of the present invention, omega-hydroxy fatty acids can be easily obtained in high purities by hydrolyzing lactones which are also the anticancer agents of the present invention.
