Great work with @elisabethjanssen.bsky.social! @chem.uzh.ch https://pubs.rsc.org/en/content/articlelanding/2026/np/d5np00076a19 Mar 2026 11:00 +0000at://did:plc:saxupedujbfhhffq6peesobj/app.bsky.feed.post/3mhftxqhaek2xhttps://bsky.app/profile/simonsieber.bsky.social/post/3lsvvq7sr3s27Thrilled to see our study on novel toxins from cyanobacteria blooms in #Fribourg in STOTEN! Our results indicate that Phormidium is the producer of cyanopeptolins, whose side chains are crucial for their activity. Great collaboration with Pilar Junier https://www.sciencedirect.com/science/article/pii/S004896972501391901 Jul 2025 14:25 +0000at://did:plc:saxupedujbfhhffq6peesobj/app.bsky.feed.post/3lsvvq7sr3s27https://bsky.app/profile/simonsieber.bsky.social/post/3log7muqo3k2dA great start to the 13th International Conference on Toxic Cyanobacteria at a beautiful venue in Crete with more than 290 participants! Fantastic work from the organizing committee !! @ictc13.bsky.social #cyanobacteria05 May 2025 10:59 +0000at://did:plc:saxupedujbfhhffq6peesobj/app.bsky.feed.post/3log7muqo3k2dhttps://bsky.app/profile/simonsieber.bsky.social/post/3lhbmrcfqas2dIt's a fantastic feeling: Alfred Werner Legat has accepted our research grant, which focuses on developing a chemoselective approach to targeting natural products!
