Linderalactone is an important sesquiterpene lactone isolated from Radix linderae. Linderalactone inhibits cancer growth by modulating the expression of apoptosis-related proteins and inhibition of JAK/STAT signalling pathway. Linderalactone also inhibits the proliferation of the lung cancer A-549 cells with an IC50 of 15 μM[1][2].

Linderalactone (0-100 μM; 24 hours; A549 cells) treatment inhibits the growth of A549 cells concentration-dependently. The IC50 of linderalactone is 15 μM[1].Linderalactone (7.5-30 μM; A549 cells) treatment induces apoptosis in A549 cells in a dose-dependent manner[1].Linderalactone (7.5-30 μM; 24 hours; A549 cells) treatment induces G2/M cell cycle arrest of A549 cells dose-dependently[1].Linderalactone (7.5-30 μM; A549 cells) inhibits the expression of STAT1, JAK1 and JAK2. Linderalactone could also inhibit the phosphorylation of pSTAT1, pSTAT-2, pJAK1 and pJAk2[1]. Cell Viability Assay[1] Cell Line: Lung cancer A549 cells
