Synthesis of Novel N-Methylmorpholine-Substituted Benzimidazolium Salts as Potential α-Glucosidase Inhibitors

open access: yesMolecules, 2022
The α-glucosidase enzyme, located in the brush border of the small intestine, is responsible for overall glycemic control in the body. It hydrolyses the 1,4-linkage in the carbohydrates to form blood-absorbable monosaccharides that ultimately increase ...

Departing from standard practices: Strategic application of value engineering in the anatomy laboratory to enhance formaldehyde extraction using high‐impact, low‐cost, and low‐maintenance solutions

open access: yesAnatomical Sciences Education, Volume 18, Issue 3, Page 241-253, March 2025.
Abstract This study describes the process of developing a high‐impact, low‐cost, and low‐maintenance air ventilation system for anatomy facilities. It employed the strategic application of Value Engineering (VE), assuring that the air ventilation system meets contemporary threshold limit values (TLVs) for formaldehyde in the working zone of dissection ...

Morpholines-(IV)

open access: yesZeitschrift für Naturforschung B, 1971
Cyclodehydrohalogenation-beta-Lactams-Morpholin-3-ones-H'-NMR Spectroscopy N-Aryl-N-chloroacetyl-2-chlorophenacylamines (2) give morpholinones 3, or beta-lactams 4, depending upon the N-aryl-substituent. N-Phenyl-N- (2,3-dibromo-3-phenylpropionyl) -4-nitrophenacylamine did not undergo base-catalysed cyclization but gave, instead, the α,β-

2-[(E)-(Morpholin-4-ylimino)methyl]-6-(morpholin-4-ylmethyl)phenol [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2013
The title compound, C16H23N3O3, contains two morpholine rings, each of which adopts a chair conformation. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond, leading to a S(6) ring. In the crystal, mol-ecules are linked into zigzag chains along the c-axis direction by C-H⋯O and C-H⋯π inter-actions.

Versatile Palladium‐Catalyzed C‐H Arylation of Fluoroarenes with 2‐Chloropyridine Derivatives

open access: yesChemistry – A European Journal, EarlyView.
Direct C─H arylation of fluoroarenes with 2‐chloropyridines is enabled by a simple Pd/SPhos system in isopropyl acetate. The method uses inexpensive reactants and shows broad scope and high yields. DFT computations explain reactivity and selectivity.

2-Deoxystreptamine Conjugates by Truncation–Derivatization of Neomycin

open access: yesPharmaceuticals, 2010
A small library of truncated neomycin-conjugates is prepared by consecutive removal of 2,6-diaminoglucose rings, oxidation-reductive amination of ribose, oxidation-conjugation of aminopyridine/aminoquinoline and finally dimerization.

Rational Design, Synthesis and Biological Evaluation of Pyrimidine-4,6-diamine derivatives as Type-II inhibitors of FLT3 Selective Against c-KIT. [PDF]

open access: yes, 2018
FMS-like Tyrosine Kinase 3 (FLT3) is a clinically validated target for acute myeloid leukemia (AML). Inhibitors targeting FLT3 have been evaluated in clinical studies and have exhibited potential to treat FLT3-driven AML.

Morpholines-(I)

open access: yesZeitschrift für Naturforschung B, 1970
ω- (N-aryl-chloracetamido) -acetophenones have been cyclized with triethylamine in warm benzene solution to the corresponding 1,4-oxazines. The reaction appears to be general for any N-aryl substituent, as long as an overall electron-withdrawing substituent is present para- or meta, in the aromatic nucleus of the acetophenone moiety.

Pharmaceuticals Made with Hydrogen: A Sustainable and Efficient Approach Using Flow Synthesis

open access: yesChemistry – A European Journal, EarlyView.
We demonstrate a sustainable strategy for pharmaceutical manufacturing by combining hydrogen, heterogeneous catalysis, and continuous flow synthesis. The development of novel catalysts and their application in a multi‐step synthesis of donepezil enabled a highly productive process with no intermediate purification.
