Highly Regioselective Carbamoylation of Electron-Deficient Nitrogen Heteroarenes with Hydrazinecarboxamides

The use of hydrazinecarboxamides as a new class of carbamoylating agents has been established through the dehydrazinative Minisci reaction of electron-deficient nitrogen heteroarenes. A wide range of electron-deficient nitrogen heteroarenes, including isoquinoline, quinoline, pyridine, phenanthridine, quinoxaline, and phthalazine, underwent copper/acid-catalyzed oxidative carbamoylation with hydrazinecarboxamide hydrochlorides to afford structurally diverse nitrogen-heteroaryl carboxamides as single regioisomers in moderate to excellent yields. The functional group tolerance was substantially demonstrated in the direct carbamoylation of quinine obviating multistep sequences involving protecting groups and prefunctionalization of the heterocycle.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 34784-05-9, help many people in the next few years.COA of Formula: C9H6BrN

Metal-Organic Anion Receptors: Arranging Urea Hydrogen-Bond Donors to Encapsulate Sulfate Ions

A new class of synthetic receptors for anions can be prepared by arranging urea hydrogen-bond donor groups on a simple metal-organic scaffold. The complex cation [PtL4]2+ (L = 8-(n-butylurea)iso-quinoline) can adopt four conformations reminiscent of calix[4]arene-based receptors; “cone”, “partial cone”, “1,2-alternate”, or “1,3-alternate”. 1H NMR solution data and solid-state X-ray structures show that a “1,2-alternate” conformation is used to bind spherical halide ions while a “cone” conformation is involved in strong binding with the tetrahedral oxy-anions such as the sulfate ion; even in a strongly competitive solvent such as DMSO.

Synthesis and study of halogenated benzylamides of some isocyclic and heterocyclic acids as potential anticonvulsants

A series of potential anticonvulsants have been synthesized. There are eight fluorobenzylamides and three chlorobenzylamides of isocyclic or heterocyclic acids. Two not halogenated benzylamides were also synthesized to compare the effect of halogenation. The aim of the research performed was to evaluate whether halogenation of the mother structure is able to improve its anticonvulsant activity. The compounds were tested in Anticonvulsant Screening Project (ASP) of Antiepileptic Drug Development Program (ADDP) of NIH. Compound 1 showed MES ED50 = 80.32 mg/kg, PI = 3.16. Compound 7 showed CKM ED50 = 56.72 mg/kg. Compound 8 showed MES ED50 = 34.23 mg/kg and scPTZ ED50 > 300 mg/kg, PI = 8.53.Compound 13 showed 6Hz ED50 = 78.96, PI = 3.37. The results indicate that fluorination does not improve activity, whereas chlorination in our experiment even reduces it.

Antituberculosis Activity of the Antimalaria Cytochrome bcc Oxidase Inhibitor SCR0911

The ability to respire and generate adenosine triphosphate (ATP) is essential for the physiology, persistence, and pathogenicity of Mycobacterium tuberculosis, which causes tuberculosis. By employing a lead repurposing strategy, the malarial cytochrome bc1 inhibitor SCR0911 was tested against mycobacteria. Docking studies were carried out to reveal potential binding and to understand the binding interactions with the target, cytochrome bcc. Whole-cell-based and in vitro assays demonstrated the potency of SCR0911 by inhibiting cell growth and ATP synthesis in both the fast- and slow-growing M. smegmatis and M. bovis bacillus Calmette-Guerin, respectively. The variety of biochemical assays and the use of a cytochrome bcc deficient mutant strain validated the cytochrome bcc oxidase as the direct target of the drug. The data demonstrate the broad-spectrum activity of SCR0911 and open the door for structure-activity relationship studies to improve the potency of new mycobacteria specific SCR0911 analogues.

Synthetic investigations of (1,3?)-bistetrahydroisoquinolines: Towards pentacyclic analogues of piperazine core alkaloids

Synthetic investigations of (1,3?)-bistetrahydroisoquinolines are reported as the key intermediates for the synthesis of ecteinascidin and phthalascidin pentacyclic structure analogues through successive Pictet-Spengler cyclization and intramolecular peptide coupling. The direct Pictet-Spengler reaction between a derivative of l-DOPA and N-protected-alpha-aminoaldehyde was first extended to the synthesis of cis-(1,3?)- bistetrahydroisoquinoline. After introduction of the required amino acid moiety, an efficient six-membered ring intramolecular peptide coupling gave rise to piperazine derivative structures. Complete structural assignments were corroborated by NMR and X-ray spectroscopic methods. Nevertheless, the optical integrity of the N-protected-alpha-aminoaldehyde seems to be sensitive to the reaction conditions. Pentacylic structures, having an anti C3-C11 backbone stereochemistry, were obtained from cyclization para- and ortho- to the 3-OH group of the l-DOPA derivative.
