Limnology and Oceanography, Volume 69, Issue 11, Page 2732-2747, November 2024.Abstract Dinophysis is an obligate mixotroph that relies on consumption of the ciliate, Mesodinium rubrum, to grow and form harmful algal blooms (HABs). In this study, blooms of Dinophysis acuminata in two NY, USA, estuaries were studied over the course of 3 yr (2019–2021) using discrete samples and an Imaging FlowCytobot (IFCB) to capture images of ...

Spirodiepoxide Strategy to the C Ring of Pectenotoxin 4: Synthesis of the C1 – C19 Sector
Organic Letters, 2010 The synthesis of a C1–C19 precursor to pectenotoxin 4 is presented. The strategy employed the functionalized allene shown. Key features include: olefin metathesis of two simple fragments to prepare the left portion of the allene-precursor ...

Diastereoselective Synthesis of the Pectenotoxin 2 Non-Anomeric AB Spiroacetal
, 2016 The reductive cyclization reaction of a cyanoacetal has been used to prepare the pectenotoxin 2 (PTX-2) AB spiroacetal with high diastereoselectively for the first time. The strategy is convergent and makes use of the axial-selective reductive lithiation

Scientific opinion on marine biotoxins in shellfish in the Republic of Croatia
Food Risk Assess Europe, Volume 2, Issue 2, April 2024.Summary Marine biotoxins are thermostable, mostly non‐protein molecules with different chemical components. According to solubility, they are divided into water‐soluble (hydrophilic) and fat‐soluble (lipophilic). The regulations of the EU and the Republic of Croatia regarding the maximum limits (ML) in live shellfish cover several groups: azaspiracids (

Synthesis of the C1–C26 Hexacyclic Subunit of Pectenotoxin 2
, 2016 Synthesis of the C1–C26 hexacyclic subunit of pectenotoxin-2 (PTX-2) is described that features a stereoselective annulation to generate the C-ring by triple asymmetric Nozaki–Hiyama–Kishi coupling followed by oxidative cyclization. Preparation of the C1–
