AKT1 and small cell lung carcinoma: 24-Methyl-cholesta-5,24(28)-diene-3β,19-diol-7β-monoacetate (MeCDDA, purified from the cultured soft coral Nephthea erecta) induced an apoptotic response in H1688 small cell lung cancer cells (20–80 μM), which was accompanied by a reduction in p-AKT and p-mTOR protein expression (10–40 μM, 24 h) [39].
