Asymmetric synthesis of cyclo-archaeol and β-glucosyl cyclo-archaeol.
An efficient asymmetric synthesis of cyclo-archaeol and β-glucosyl cyclo-archaeol is presented employing catalytic asymmetric conjugate addition and catalytic epoxide ring opening as the key steps. Their occurrence in deep sea hydrothermal vents has been confirmed by chromatographic comparison with natural samples.
متن کاملCyclo(l-tyrosyl-l-tryptophanyl) dimethylformamide solvate
THE STRUCTURE OF THE TITLE COMPOUND [SYSTEMATIC NAME: (3S,6S)-3-(4-hydroxy-benz-yl)-6-(1H-indol-3-ylmeth-yl)piperazine-2,5-dione dimethyl-formamide solvate], C(20)H(19)N(3)O(3)·C(3)H(7)NO, contains hydrogen-bonded tapes typical for diketopiperazines. The structure is stabilized by strong inter-molecular inter-actions of the types O-H⋯O and N-H⋯O involving the dipeptide and the solvent mol-ecule...
متن کاملSynthesis of trifunctional cyclo-β-tripeptide templates
The concept of template-assembled synthetic proteins (TASP) describes a central scaffold that predefines the three dimensional structure for diverse molecules linked to this platform. Cyclic β-tripeptides are interesting candidates for use as templates due to their conformationally defined structure, stability to enzymatic degradation, and ability to form intermolecular stacked tubular structur...
متن کاملLactobacillus plantarum MiLAB 393 produces the antifungal cyclic dipeptides cyclo(L-Phe-L-Pro) and cyclo(L-Phe-trans-4-OH-L-Pro) and 3-phenyllactic acid.
We have isolated a Lactobacillus plantarum strain (MiLAB 393) from grass silage that produces broad-spectrum antifungal compounds, active against food- and feed-borne filamentous fungi and yeasts in a dual-culture agar plate assay. Fusarium sporotrichioides and Aspergillus fumigatus were the most sensitive among the molds, and Kluyveromyces marxianus was the most sensitive yeast species. No inh...

that produces opioid-like effects on the central nervous system.1 Cleavage of the β-endorphin C-terminal in the brain and pituitary gland yields the biologically active dipeptide glycyl-Lglutamine (Gly-L-Gln, β-endorphin 30-31), which inhibits βendorphin-induced cardiorespiratory depression.2,3 The stereospecificity of this effect is evident, since Gly-D-Gln has recently been reported to be ina...
