({E}uphorbiaceae) is a thorn-covered tree widespread in {S}outh {A}merica, {A}frica and {A}sia which produces an irritating milky latex containing numerous secondary metabolites, notably daphnane-type diter-penes known as {P}rotein {K}inase {C} activators. {F}ractionation of a dichloromethane extract of the latex led to the isolation of five new daphnane diterpenes (1-5), along with two known analogs (6-7) including huratoxin. {H}uratoxin (6) and 4 & {PRIME};,5 & {PRIME};-epoxyhuratoxin (4) were found to exhibit significant and selective cell growth inhibition against colorectal cancer cell line {C}aco-2 and primary colorectal cancer cells cultured as colonoids. {T}he un-derlying mechanism of 4 and 6 was further investigated revealing the involvement of {PKC} & zeta;in the cytostatic activity.}, keywords = {{E}uphorbiaceae ; {H}ura crepitans ; {D}aphnane diterpenes ; {C}olorectal cancer ; {C}aco-2 cells ; {P}rotein {K}inase {C}}, booktitle = {}, journal = {{B}ioorganic and {M}edicinal {C}hemistry}, volume = {90}, numero = {}, pages = {117366 [17 ]}, ISSN = {0968-0896}, year = {2023}, DOI = {10.1016/j.bmc.2023.117366}, URL = {https://www.documentation.ird.fr/hor/fdi:010088184}, }
