The group of M. Jaspars has been working with samples of Dermacoccus abyssi MT 1.1T, a piezotolerant Actinomycete. It was collected in 1998 and isolated in 2006 from a Mariana Trench sediment. A series of new phenazines were isolated and their structures elucidated. One of these compounds was dermacozine O.

Several types of polyketide-derived pigments can be found in crinoids. The group of Lum explored samples collected from different locations of the Great Barrier Reef. The analysis of C. rotalaria extracts by UHPLC-MS in conjunction with database searching led to the isolation and structure elucidation of a series of new taurine-conjugated anthraquinones, including comatulin A.

Interpreting the pattern of lines on a mass spectrum may feel overwhelming at first glance. However, with a little background knowledge of the theory behind mass spectrometry techniques, you can begin to recognize what to look for in your mass spectrum and obtain the information you need.

While pharmaceutical stress testing is challenging, it is necessary for protecting patient health and meeting regulatory requirements. Thorough stress testing paired with strategic data management is the best way to maintain quality pharmaceuticals. In this blog, Jesse Harris discusses the use of Luminata to simplify pharmaceutical stress testing.

Lobocrassin A Cembrane-type metabolites are among the largest group of diterpenoids isolated from octocorals. A rich source of such compounds has been found to be Lobophytum crassum, a soft coral from the family of Alcyoniidae. This coral has been studied by Kao et al [1], and five new cembrane derivatives have been isolated. Amongst them...

Is there anything that analytical chemists hate more than false positives and false negatives? While it is impossible to eliminate error completely, it is possible to control it. Understanding the relationship between false positives and negatives allows us to optimize our experimental design. We discuss more in this blog post.
