Paris saponin VII (Dioscini) 是从延龄草的根和根茎中分离的一种甾体皂苷。它减弱线粒体膜电位,增加凋亡相关蛋白的表达,并降低Bcl-2、caspase-9、caspase-3、PARP-1和p-Akt 的蛋白表达水平。它在 K562 ADR 细胞中诱导强烈的自噬,可研究白血病。
FD223 is a potent and selective phosphoinositide 3-kinase delta (PI3Kδ) inhibitor. FD223 displays high potency (IC50=1 nM) and good selectivity over other isoforms (IC50s of 51 nM, 29 nM and 37 nM, respectively for α, β and γ). FD223 exhibits efficient inhibition of the proliferation of acute myeloid leukemia (AML) cell lines by suppressing p-AKT Ser473 thus causing G1 phase arrest during the cell cycle. FD223 has potential for the research of leukemia such as AML[1].
Dehydroglyasperin C is a potent NAD(P)H:oxidoquinone reductase (NQO1) and phase 2 enzyme inducer. Dehydroglyasperin C possesses potent antioxidant, cancer chemopreventive, and neuroprotective activities, it has protective effects against chronic diseases
LeDSF3 is a regulator of the biosynthesis of the antifungal polycyclic tetramate macrolactam HSAF in Lysobacter enzymogenes and anti-tumor agent. LeDSF3 down-regulates p-AKT and activates caspase-3.
Indium (III) thiosemicarbazone 5b is an anticancer compound demonstrating cytotoxicity against various cancer cell lines including A549, MCF-7 breast, cisplatin-resistant MCF-7/DDP breast, and Hl 7702 liver cancer cells, with IC50 values of 2.41, 1.97, 2.11, and 8.95 µM, respectively. It effectively lowers PI3K, Akt, mTOR, P-gp, and GSH levels in MCF-7/DDP cells. In vivo studies show that at a dosage of 2.5 µmol/kg, indium (III) thiosemicarbazone 5b significantly reduces tumor weight and volume in MCF-7/DDP mouse xenograft models. Furthermore, liposomes formulated with this compound promote apoptosis and pro-death autophagy in MCF-7/DDP cells, alongside notable reductions in tumor volume and weight, showcasing its potential as a therapeutic agent in cancer treatment.
PABA/NO is a novel glutathione-S-transferase-p-activated nitric oxide donor, inhibiting proliferation and inducing apoptosis by targeting PI3K/AKT/mTOR and MEK/ERK pathways in hepatocellular carcinoma cells.
ASK120067 is a potent and orally active inhibitor of EGFRT790M (IC50:0.3 nM) with selectivity over EGFRWT (IC50:6.0 nM). ASK120067 is a third-generation EGFR-TKI for the research of non-small cell lung cancer (NSCLC)[1]. In the in vitro kinase assay ASK120067 potently inhibits the EGFR L858R T790M and EGFR T790M resistant mutants with IC50 values of 0.3 nM and 0.5 nM, respectively, as well as the EGFRexon19del sensitizing mutant (IC50= 0.5 nM). The 50 of ASK120067 against wild-type EGFR (EGFRWT) is 6 nM[1].ASK120067 selectively inhibits the growth of EGFR-mutant cell lines and exhibits potent antiproliferative activity in the mutant EGFR NSCLC cells, with IC50 values of 12 nM, 6 nM and 2 nM against NCI-H1975 (T790M mutation), PC-9, and HCC827 cells (sensitizing mutations), respectively. However, it shows moderate or weak anti-growth activities in A431, LoVo and A549 cells (EGFRWT), with IC50 values ranging from 338 nM to 1541 nM[1].ASK120067 (0.1-100 nM) inhibits the phosphorylation of EGFR at Tyrosine residue 1068 and its downstream signaling proteins AKT and ERK in NCI-H1975 cells (EGFRL858R T790M) even at low dosage (0.1-1 nM). Additionally, ASK120067 inhibits p-EGFR and p-Akt and p-erk in EGFR WT A431 cell until the concentration reaches 10 to 100 nM[1]. ASK120067 (oral gavage; 5-20 mg kg; once daily; 21 days) results in significantly regressed tumor growth, with a tumor growth inhibition (TGI) rate of 85.7%, and administration of 10 mg kg ASK120067 causes dramatic tumor shrinkage with a TGI rate of 99.3%, exhibiting a similar potency with Osimertinib[1].
