Gochnatiolide A, a dimeric sesquiterpene isolated from Ainsliaea henryi, demonstrates antiproliferative properties against various cell lines, including kidney, melanoma, ovarian-resistant, and glioma [1] [2].

Gochnatiolide A, at concentrations ranging from 0.25 to 250 μg/mL over 48 hours, inhibits cell growth. The Total Growth Inhibition (TGI) values for the following cell lines are as follows: 786-O at 0.42 μg/mL, UACC-62 at 0.49 μg/mL, NCI-ADR/RES at 0.70 μg/mL, U251 at 1.09 μg/mL, MCF-7 at 1.69 μg/mL, NCI-H460 at 4.66 μg/mL, HT-29 at 5.42 μg/mL, PC-3 at 6.63 μg/mL, OVCAR-3 at 54.73 μg/mL, VERO at 13.13 μg/mL, and K562 at 114.87 μg/mL [2].
