Try google image search.

Do you have access to Scifinder? Try putting in the entire molecule, and if that doesn't give you an answer, put in pieces of it and do substructure searches.

Strange. I did an image search with Google Chrome (using the url of the image, but I don't see why searching with the image itself shouldn't work) and got one hit, which was exactly what you are looking for. Took me just a few seconds. Note I am not talking about standard search, but about image search. Same Google, different tool.

If you were in the mainland China I would suspect China firewall to block the result, but you are not.

Which is why we do occasionally still use common names  :D

That's a fascinating molecule.

How does the coral itself synthesize such a complex molecule, anyone know?

Also, do coral cells not have Na-K pumps? How does Palytoxin not poison the coral?

The simplest answer is that it contains the toxin in an inactive form, or keeps it in a cellular vesicle to protect itself.  Or maybe its particular cell membrane ion pumps are simply immune.  Although, generally speaking, all cells have ion pumps to alter their interior environment and local environment, this charge differential is easily noticed, and manipulated with micro-electrodes.  This is the basis of the earliest work with neurons.  I wanted to provide a link, but Wikipedia is a little all over the place on the topic.

That all depends on how reasonable we're all willing to be.  I just want my friends back, except for Cartman, you can keep him.

Are vesicles typically impermeable to such molecules?

How would someone confirm they made that above structure?

Wouldn't the NMR be too complicated?
