The bifunctionalized mesoporous organosilica spheres with trans-(1R,2R)-diaminocyclohexane (DACH) in the pore were synthesized and their application as chiral stationary phase in high-performance liquid chromatography (HPLC) was demonstrated. Bifunctionalized mesoporous organosilica spheres with narrow particle size distribution of 5-7 microm were prepared by the co-condensation of N-[3-(trieth...

Gallic acid esters could be synthesized biologically by tannase in organic media, among which is propyl gallate, an antioxidant widely used as a food additive. Efficient intracellular expression of Aspergillus oryzae tannase was achieved in Pichia pastoris under the control of the AOX1 promoter, and the productivity of recombinant tannase was 960 U/L or 64 U/g dry mass. The recombinant P. pasto...

Uncompetitive N-methyl-d-aspartate (NMDA) receptor antagonists with fast off-rate (UFO) may represent promising drug candidates for various neurodegenerative disorders. In this study, we report that bis(propyl)-cognitin, a novel dimeric acetylcholinesterase inhibitor and gamma-aminobutyric acid subtype A receptor antagonist, is such an antagonist of NMDA receptors. In cultured rat hippocampal n...

ME T H Y L N P R O P Y L ETHER is an isomer of di-ethyl ether and possesses the formula CHs-O(CHI)J-CHJ. The physical properties of the two drugs are similar, and the vapour pressure curve of methyl-n-propyl ether is such that it may be used in the Oxford Vaporizer No. 1 without any alteration in the calibration of the instrument (see Figure). Methyl-n-propyl ether has a very unpleasant pungent...

Neutral cannabinoids with a pentyl side chain-for example, cannabidiol, tetrahydrocannabinol, and cannabinol-are generally accompanied by homologs with a propyl side chain, of which at least one has psychotropic activity. Samples of hashish and marihuana from Asia especially sometimes have abundant amounts of propyl cannabinoids, the quantities being of the same order as that of the accompanyin...
