A new secosterol from the Indonesian octocoral Pachyclavularia violacea.
A new secosterol (1), along with pachyclavulariaenone B (3), was isolated from Pachyclavularia violacea. The structures of these compounds were established on the basis of the NMR and MS experiments.
New Xenia diterpenoids from the Indonesian soft coral Xenia sp.
TLDR
Two new xeniolides and 9-hydroxyxeniolide-F have been isolated from Xenia sp. Expand
Structural characterization of vanchrobactin, a new catechol siderophore produced by the fish pathogen Vibrio anguillarum serotype O2
Abstract Vanchrobactin, a new catecol-type siderophore produced by cells of the fish pathogen Vibrio anguillarum serotype O2, has been isolated from the supernatants of iron-deficient cultures. ItsExpand
Optimization strategies for the analysis and purification of drug discovery compounds by reversed-phase high-performance liquid chromatography with high-pH mobile phases.
TLDR
A cost-effective strategy for maximizing the purification of drug discovery compounds is proposed and the single prerequisite for this approach is an analytical LC-UV-MS run, therefore the system has the ability to collect only fractions likely to contain the target product. Expand
Placing supercritical fluid chromatography one step ahead of reversed-phase high performance liquid chromatography in the achiral purification arena: a hydrophilic interaction chromatography
TLDR
The success of the new approach has enabled the group to shift from RP-HPLC/MS to SFC/MS as the primary technique for purification within the achiral area. Expand
An approach to speed up the isolation of hydrophilic metabolites from natural sources at semipreparative level by using a hydrophilic-lipophilic balance/mixed-mode strong cation
TLDR
This methodology was successfully applied to the re-isolation of small water soluble compounds with completely different structures from two different natural extracts such as a dipeptide from a bacterium culture broth and a pyrrolidine bearing a carboxylic acid moiety from a sponge. Expand
Vanchrobactin: absolute configuration and total synthesis
Abstract The stereochemistry of vanchrobactin, a siderophore produced by the bacterial fish pathogen Vibrio anguillarum serotype O2, was elucidated by chiral capillary electrophoresis analysis andExpand
