Identifying the targets of bioactivesmallmolecules is a challenging endeavor for which no general solution currently exists. Classical affinity purification experiments suffer from the need to functionalise a bioactive compound and link it to a solid support, which may interfere with target binding. A modern mass spectrometry-based proteomics technique that has partially circumvented this problem
biosynthesis. However, in the case of pellasoren, one chiral center was not predicted correctly. The absolute configuration was verified by total synthesis, which also demonstrated that stereoselective protonations can be successfully applied to natural products synthesis.

The natural product salicylihalamide is a potent inhibitor of the Vacuolar ATPase (V-ATPase), a potential target for antitumor chemotherapy. We generated salicylihalamide-resistant tumor cell lines typified by an overexpansion of lysosomal organelles. We also found that many tumor cell lines upregulate tissue-specific plasmalemmal V-ATPases, and hypothesize that tumors that derive their energy from
General Synthesis of Highly Functionalized Cyclopentane Segments for the Preparation of Jatrophane Diterpenes

Short and efficient syntheses of two diastereomeric cyclopentane segments present in most jatrophanediterpenes were achieved. Key steps are a stereoselective C-2 elongation, an RCM, and a hydroboration reaction. An orthogonal protecting group methodology makes these segments useful building blocks for diterpene synthesis.
