To study how conserved fundamental concepts of the heat stress response (HSR) are in photosynthetic eukaryotes, we applied pharmaceutical and antisense/amiRNA approaches to the unicellular green alga Chlamydomonas reinhardtii. The Chlamydomonas HSR appears to be triggered by the accumulation of unfolded proteins, as it was induced at ambient temperatures by feeding cells with the arginine analo...

(E)-13-(2-Bromo­phen­yl)micheliolide

The title compound, C21H23BrO3 [systematic name: (3E,3aS,6Z,9R,9aS,9bS)-3-(2-bromo-benzyl-idene)-9-hy-droxy-6,9-dimethyl-3,3a,4,5,7,8,9,9a-octa-hydro-azuleno[4,5-b]furan-2(9bH)-one] was prepared by the reaction of 1-bromo-2-iodo-benzene with micheliolide [systematic name: (3aS,R,9aS,9bS,Z)-9-hy-droxy-6,9-dimethyl-3-methyl-ene-3,3a,4,5,7,8,9,9a-octa-hydro-azuleno[4,5-b]furan-2(9bH)-one] under He...

(E)-13-(4-Amino­phen­yl)parthenolide

The title compound, C21H25NO3 [systematic name: (3aS,9aR,10aR,10bS,E)-3-[(E)-4-(4-amino-benzyl-idene)-6,9a-dimethyl-3a,4,5,8,9,9a,10a,10b-octa-hydro-oxireno[2',3':9,10]cyclo-deca-[1,2-b]furan-2(3H)-one] was obtained from the reaction of parthenolide [synonym: 4,5-ep-oxy-germacra-1(10),11(13)-dieno-12,6-lactone] with 4-iodo-aniline under Heck reaction conditions. It was identified as the E-isome...

13-(N,N-Di­methyl­amino)­micheliolide 0.08-hydrate

The title compound, C17H27NO3·0.08H2O {sytematic name: (3R,3aS,9R,9aS,9bS)-3-[(di-methyl-amino)-meth-yl]-9-hy-droxy-6,9-dimethyl-3,3a,4,5,7,8,9,9a-octa-hydro-azuleno[4,5-b]furan-2(9bH)-one 0.08-hydrate}, exhibits intra-molecular O-H⋯O hydrogen bonding to form a ring of graph-set motif S(6). As well as this intra-molecular hydrogen bond with the lactone-ring O atom, the hy-droxy H atom forms an ...
