Preparation of Benzalkonium Salts Differing in the Length of a Side Alkyl Chain

Molecules, 2007
Benzalkonium salts are widely used as disinfectants, biocides and detergents,among a variety of other applications. The cationic surface-activity of these saltsdetermines their potential to act as a biocide on both target and non-target organisms. Inthis

Divergent synthesis and antitumour activity of novel conformationally constrained (−)-muricatacin analogues [PDF]

Journal of the Serbian Chemical Society, 2023
Four novel conformationally restricted (–)-muricatacin analogues, bearing a methoxy group at the C-5 position and with an alkoxymethyl group аs the C-7 side chain, have been synthesised and their in vitro antiproliferative activity was evaluated against ...

Sterol side chain length and structure affect the clearance of chylomicron-like lipid emulsions in rats and mice

Journal of Lipid Research, 1998
In previous work we found that sterols such as cholesterol were essential for physiological plasma clearance of lipid emulsions mimicking the structure of mammalian triglyceride-rich lipoproteins.

Network structure of polyfluorene sheets as a function of alkyl side chain length [PDF]

Physical Review E, 2011
The formation of self-organized structures in poly(9,9-di-n-alkylfluorene)s ∼1 vol % methylcyclohexane (MCH) and deuterated MCH (MCH-d(14)) solutions was studied at room temperature using neutron and x-ray scattering (with the overall q range of 0.00058-4.29 Å(-1)) and optical spectroscopy. The number of side chain carbons (N) ranged from 6 to 10.

Extensin arabinoside chain length is modulated in elongating cotton fibre

The Cell Surface, 2019
Cotton fibre provides a unicellular model system for studying cell expansion and secondary cell wall deposition. Mature cotton fibres are mainly composed of cellulose while the walls of developing fibre cells contain a variety of polysaccharides and ...

Design, synthesis, conformational analysis, and biological activity of Cα1-to-Cα6 1,4- and 4,1-disubstituted 1H-[1,2,3]triazol-1-yl-bridged oxytocin analogues

Journal of Enzyme Inhibition and Medicinal Chemistry, 2023
Oxytocin (OT) is a neurohypophyseal peptide hormone containing a disulphide-bridged pseudocyclic conformation. The biomedical use of OT peptides is limited amongst others by disadvantageous pharmacokinetic parameters.

Effect of Block Length and Side Chain Length Ratios on Determining a Multicompartment Micelle Structure

The Journal of Physical Chemistry B, 2019
Previous work has identified the importance of the lipophilic-fluorophilic block length ratio Rl in predicting the morphology of linear lipophilic-hydrophilic-fluorophilic (hereafter referred to as BAC) micelle systems. Here, a generalized form R of this structural parameter is developed that makes no assumption of BAC triblock co-polymer linearity ...

Helix Propensities of Basic Amino Acids Increase with the Length of the Side-chain [PDF]

Journal of Molecular Biology, 1996
Helix formation in a 17-residue alanine-lysine peptide and analogous peptides with specific lysine --> X substitutions, where X is 2,3-diamino-L-propionic acid, 2, 4-diamino-L-butyric acid or L-ornithine, have been examined using circular dichroism measurements.

An extreme-phenotype genome‐wide association study identifies candidate cannabinoid pathway genes in Cannabis

Scientific Reports, 2020
Cannabis produces a class of isoprenylated resorcinyl polyketides known as cannabinoids, a subset of which are medically important and exclusive to this plant. The cannabinoid alkyl group is a critical structural feature that governs therapeutic activity.

Effects of side-chain length on the magnetic response of discotic metallomesogens [PDF]

Journal of Applied Crystallography, 2007
The magnetic responses of columnar superstructures of discotic metallomesogens with different alkyl side-chain lengths, cobalt octa(n-alkylthio)porphyrazine (CoSx, where x is the peripheral n-alkyl chain length, x = 10, 12, 14), have been investigated by small-angle neutron scattering (SANS).
