Evaluation of N-alkyl isatins and indoles as acetylcholinesterase and butyrylcholinesterase inhibitors

Journal of Enzyme Inhibition and Medicinal Chemistry
Two series of N-alkyl isatins and N-alkyl indoles varying in size of the alkyl group were synthesised and evaluated for inhibition of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE).

Functionalizing Graphene Oxide with Alkylamine by Gamma-ray Irradiation Method

Nanomaterials, 2017
A gamma-ray irradiation technique was used to functionalize graphene oxide (GO) with alkylamines of various alkyl chain lengths. Functionalization of the alkyl chains onto the GO was confirmed by nuclear magnetic resonance (1H NMR), Fourier transform ...

Ehrlich ascites tumor cell surface membranes: an abnormality in ether lipid content

Journal of Lipid Research, 1978
Most mammalian neoplasms have a defect in ether lipid content manifested by the presence of abnormally large quantities of O-alkyl glyceryl ethers, in contrast to normal tissues in which the alk-1-enyl structure predominates.

Defective lipid remodeling of GPI anchors in peroxisomal disorders, Zellweger syndrome, and rhizomelic chondrodysplasia punctata

Journal of Lipid Research, 2012
Many cell surface proteins in mammalian cells are anchored to the plasma membrane via glycosylphosphatidylinositol (GPI). The predominant form of mammalian GPI contains 1-alkyl-2-acyl phosphatidylinositol (PI), which is generated by lipid remodeling from
