Lucidumone Meroterpenoids are natural products containing a terpenoid and a non-terpenoid part. There have been many classes of such compounds isolated and characterized so far, from various natural sources, several of which have been found to have a wide range of biological activities. Meroterpenoids from various fungi usually show considerable biological activity and for this...

Spirobisnaphthalenes are a relatively new and rare family of secondary metabolites. Their core structure usually consists of two bicyclo[4.4.0]decane units, connected with one another through at least one spiro center. The reported compound is a novel symmetric spirobisnaphthalene with a unique structural feature. Spiroaxillarone A, molecular formula C19H12O6.

There are numerous ways that the 3D structure of a molecule can be elucidated, including the use of our own ACD/Structure Elucidator software. I had the chance to sit down with Dimitris Argyropoulos, our NMR Business Manager, after SMASH 2019 and discuss 3D structure elucidation and the technology involved in its current and future use.

Reliable structure verification of candidate molecules is at the very core of any successful chemical discovery or development program. NMR provides unprecedented levels of information for unraveling the actual structure of compounds, and is an essential tool for chemists to confirm that they made what they intended to make. Read on to learn about ACD/Labs' efforts in the area of structure verification.

Chloraserrtone A, a new sesquiterpenoid dimer with two lindenane-type sesquiterpenoid monomers bridged by two six-membered rings, was isolated from Chloranthus serratus by Bai et al. It represents the first lindenane-type sesquiterpenoid dimer with an extremely unique skeleton, molecular formula C3H36O9.
