FLLL12
FLLL12 (GO-Y026) is a curcumin analog anticancer agent. FLLL12 inhibits the phosphorylation of AKT, Bcl-2, Bid, EGFR, mTOR, FOXO1a, FOXO3a, STAT3, HER2/neu, as well as pancreatic AKT/STAT3; upregulates the expression of Bim and DR5; and activates PTPs. FLLL12 regulates downstream pathways, induces mitochondria-mediated and DR5-dependent extrinsic apoptosis, inhibits cancer cell viability, proliferation, anchorage-independent growth and migration, and exerts a synergistic effect with Doxorubicin (HY-15142A). FLLL12 can be used in research related to head and neck squamous cell carcinoma, breast cancer, prostate cancer, pancreatic cancer, lung cancer, colon cancer and colorectal cancer.

FLLL12 (GO-Y026) potently inhibits the growth of human colon cancer HCT-116 cells after 48 h exposure, with a GI50 value of 0.8 μM[1].
FLLL12 (0.5-5 μM; 72 h) potently inhibits the viability of MDA-MB-468, MDA-MB-231, SK-BR-3, BT-474, MDA-MB-453, MCF-7, PC-3 and DU145 cancer cells, with IC50 values of 0.3, 2.7, 3.8, 1.8, 1.3, 1.7, 3.6 and 3 μM, respectively, while showing extremely low toxicity against the normal human lung fibroblast cell line WI-38[2].
FLLL12 (1-10 μM; 24 h) significantly inhibits the DNA-binding activity of STAT3 in MDA-MB-231, SK-BR-3 and DU145 cancer cells, and suppresses STAT3-dependent transcriptional activity in stably transfected MDA-MB-231 cells in a dose-dependent manner[2].
FLLL12 (1-5 μM; 2 weeks) inhibits anchorage-independent colony formation in MDA-MB-231 and SK-BR-3 breast cancer cells. At the concentration of 5 μM, it reduces the number of colonies in MDA-MB-231 cells by approximately 95% and almost completely suppresses colony formation in SK-BR-3 cells[2].
FLLL12 (5-10 μM; 4 h) inhibits the migration of MDA-MB-231 breast cancer cells in a dose-dependent manner, reducing the wound healing rate to approximately 65% and 28% of that in the control group at concentrations of 5 μM and 10 μM, respectively, with no significant cytotoxicity[2].
FLLL12 (5 μM; 72 h) acts synergistically with Doxorubicin (HY-15142A) (100-400 nM) to inhibit the viability of MDA-MB-231 breast cancer cells, with a combination index value <1[2].

FLLL12 (1-3 μM; 24 h) regulates the expression of Bcl-2 family proteins in Tu212 and Tu686 head and neck squamous cell carcinoma cells; it decreases the levels of Bcl-2 and full-length Bid, and increases the level of Bim, thereby promoting cell apoptosis[6].
FLLL12 (2-3 μM; 48 h) induces apoptosis in Tu686 head and neck squamous cell carcinoma (SCCHN) cells, while overexpression of Bcl-2 significantly attenuates this effect, confirming that Bcl-2 is a key mediator of the pro-apoptotic effect of FLLL12[6].
FLLL12 (1-3 μM) upregulates the expression of Bcl-2 mRNA in Tu212 and Tu686 head and neck squamous cell carcinoma cells, indicating that its inhibitory effect on Bcl-2 protein occurs at the translational level[6].
FLLL12 (1-3 μM) inhibits the expression of EGFR and AKT mRNA in Tu212 and Tu686 head and neck squamous cell carcinoma (SCCHN) cells, indicating that its inhibitory effect on EGFR and AKT proteins occurs at the transcriptional level[6].
FLLL12 (3 μM; 48 h) induces apoptosis in Tu686 head and neck squamous cell carcinoma (SCCHN) cells, and knockdown of Bim significantly attenuates this effect, confirming that Bim is a key mediator of the pro-apoptotic action of FLLL12[6].
FLLL12 (3 μM; 48 h) induces apoptosis in Tu686 head and neck squamous cell carcinoma (SCCHN) cells, and knockdown of Bid significantly attenuates this effect, confirming that Bid is a key mediator of the apoptotic effect of FLLL12[6].
FLLL12 (5-10 μM; 24 h) downregulates the expression of HER2/neu in BT-474, SK-BR-3 and MDA-MB-453 breast cancer cells, and inhibits the phosphorylation of AKT Ser473 in MDA-MB-453 breast cancer cells and PC-3 prostate cancer cells. Meanwhile, FLLL12 increases the levels of cleaved PARP in BT-474, SK-BR-3, MDA-MB-453 and PC-3 cells, and elevates the levels of cleaved caspase-3 in SK-BR-3, MDA-MB-453 and PC-3 cells, indicating that it induces cell apoptosis[2].
FLLL12 (10 μM; 24 h) inhibits the phosphorylation of STAT3 (Tyr705) in MDA-MB-231, SK-BR-3 and DU145 cancer cells, induces apoptosis in these cancer cells, and does not trigger apoptosis in normal HMEC or WI-38 cells[2].
FLLL12 (5-10 μM; 24-48 h) inhibits the phosphorylation of STAT3 and induces apoptosis in PANC-1, BXPC-3 and HPAC human pancreatic cancer cells via cleaved caspase-3 or cleaved PARP. After 24-48 h of treatment, 10 μmol/l of this agent also inhibits the phosphorylation of AKT in BXPC-3 cells[3].
FLLL12 (5-10 μM; 24-48 h) inhibits STAT3 phosphorylation and induces apoptosis in PANC-1, HPAC and MIA-PACA-2 human pancreatic cancer cells[3].
FLLL12 (3-5 μM; 48 h) induces approximately 80% apoptosis in premalignant and malignant human lung cancer cell lines in a dose- and time-dependent manner[5].
FLLL12 induces apoptosis in human lung cancer cell lines H1299, H292 and A549, which is evidenced by the cleavage of caspase-3 and PARP[5].
FLLL12 (24 h) induces apoptosis in human lung cancer cell lines A549, H1299 and H292 via a pathway dependent on death receptor 5 (DR5) and requiring the involvement of caspase-8 and Bid, in which DR5 and caspase-8 play more critical roles than Bid[5].
FLLL12 (incubated for 24 h) activates caspase-8 and cleaves Bid into tBid in human lung cancer cell lines A549 and H1299, thereby inducing apoptosis[5].
FLLL12 (24 h) induces the expression of DR5 and subsequent apoptosis in the human lung cancer cell line A549, and this process depends on the activation of protein tyrosine phosphatases (PTPs); because inhibition of PTPs (but not alkaline phosphatase) blocks these effects[5].
FLLL12 induces apoptosis in human lung cancer cell lines H292 and H1299 in a p53- and p73-independent manner[5].
FLLL12 (2.5-5 μM; 24 h) induces apoptosis in human colorectal cancer cells HCT116, HT-29 and SW480 (as confirmed by cleaved PARP and cleaved caspase-3), but fails to induce the production of cleaved PARP in normal human lung fibroblasts WI-38 and mammary epithelial cells MCF-10A[4].
FLLL12 (1-3 μM; 24-48 h) inhibits the phosphorylation and total protein levels of EGFR and AKT in Tu212, Tu686 and MSK-Leuk1 head and neck squamous cell carcinoma (SCCHN) cells, with the inhibition of phosphorylated AKT occurring earlier than the downregulation of total AKT[6].
FLLL12 (1-3 μM; 48 h) induces apoptosis in Tu686 SCCHN cells, and overexpression of constitutively active AKT significantly attenuates this effect, confirming that AKT inhibition is a key mediator of the pro-apoptotic effect of FLLL12[6].
Treatment of immortalized human pancreatic ductal epithelial (HPDE) cells with FLLL12 (5 μM; 24-48 h) for 24-48 h does not induce apoptosis (detected via activated caspase-3)[3].
FLLL12 (24 h; 2 h) post-transcriptionally (possibly at the translational level) regulates the expression of DR5 in human lung cancer cell lines A549 and H1299, with no effect on DR5 mRNA levels[5].
