PK11000 is a p53 targeting compound, has anti-tumor activities through activation of unstable p53.

CCT128930 is a potent, ATP-competitive and selective inhibitor of Akt2 with IC50 of 6 nM, 28-fold greater selectivity for Akt2 than the closely related PKA kinase.

Lapatinib (GW572016) is an inhibitor of ErbB2 and EGFR (IC50=9.2 10.8 nM) with oral activity. Lapatinib has antitumor activity and can be used to treat advanced or metastatic breast cancer with HER2 overexpression.

Buformin hydrochloride (NSC-528218) is a potent AMPK activator,an oral antidiabetic drug of the biguanide class. Buformin delays the absorption of glucose from the gastrointestinal tract increases insulin sensitivity and glucose uptake into cells and inhibits synthesis of glucose by the liver. Biguanides may antagonize the action of glucagon, thus reducing fasting glucose levels.

Neratinib (HKI-272) (HKI-272) is an orally available, irreversible tyrosine kinase inhibitor for HER2 and EGFR (IC50: 59 92 nM), respectively.

Tanespimycin (KOS 953) (17-AAG) is an inhibitor of Hsp90 that selectively inhibits BT474 tumor cell Hsp90 (IC50: 5 nM).

FT113 is a novel potent inhibitor of fatty acid synthase (fasn, IC50 : 213 nM),and exhibits anti-cancer activity

BTK-IN-38 (Example 125) is an efficacious inhibitor of BTK. It effectively suppresses the proliferation of DOHH2 and BT474 cells, with IC50 values of 114 nM and 340 nM, respectively.

BBO-10203 (Compound 758) binds to the RBD region of PI3Kα, hindering the interaction of K-, H-, and N-Ras with PI3Kα. It inhibits pAKT with an IC50 of less than 0.1 pM in BT474 cells.

Timosaponin AIII (Timosaponin A3) induces autophagy in HeLa cells followed by apoptotic cell death (IC50: 10 μM). The Timosaponin AIII cellular response is mediated via inhibition of mTORC1 and induction of ER stress (IC50: 2.5 μM, BT474 cells; 6 μM, MDAMB231). The Timosaponin AIII pro-apoptotic response is selective for tumor cells over normal cells but autophagy is induced in both.

p-SCN-Bn-HOPO is an excellent bifunctional chelating agent for (89)Zr ImmunoPET, with low background, good tumor-organ contrast, and importantly, very low bone uptake for BT474 breast cancer imaging.

CC260, a selective inhibitor for PI5P4Kα and PI5P4Kβ with Kis of 40 nM and 30 nM respectively, exhibits minimal to no inhibition against other protein kinases like Plk1 and RSK2. It is applicable in the research of cell energy metabolism, diabetes, and cancer[1].

1. Furanodienone has effects on MCF-7 cells are mediated, at least in part, by inhibiting ERα signaling. 2. Furanodienone inhibits EGFR HER2 signaling pathway in BT474 and SKBR3 cells, the effect is specifically dependent on the expression of HER2 but not EGFR .

CCT128930 hydrochloride (CCT128930 hydrochloride) is a potent and selective inhibitor of AKT with IC50 of 6 nM. CCT128930 hydrochloride induces cell cycle arrest, DNA damage, and autophagy. CCT128930 hydrochloride has 28-fold selectivity over the closely related PKA kinase (IC50: 168 nM) through the targeting of Met282 of AKT, as well as 20-fold selectivity over p70S6K (IC50: 120 nM).

CNBCA, a selective and potent competitive inhibitor of the SHP2 enzyme, exhibits an IC50 value of 0.87 μM. It binds to the full-length SHP2, effectively inhibiting its enzyme activity, as well as impeding pAkt and pERK1 2. Furthermore, CNBCA suppresses the proliferation of BT474 and MDA-MB468 cells, indicating potential utility in breast cancer research [1].

Fasnall, a fatty acid synthase (FASN) inhibitor, exhibits an IC50 of 3.71 μM against the human recombinant enzyme. It halts tritiated acetate incorporation into lipids (IC50= 5.84 μM), boosts ceramide levels, and triggers lipid droplet formation in BT474 HER2+ breast cancer cells. Demonstrating antiproliferative effects on various breast cancer cell lines, including non-tumorigenic MCF-10A and tumorigenic MCF-7, MDA-MB-468, BT474, and SK-BR-3, its efficacy is directly linked to FASN expression in vitro. In murine models of HER2+ breast cancer, particularly the MMTV-Neu model, Fasnall significantly reduces tumor volume and extends survival. Furthermore, it enhances the efficacy of carboplatin in vivo, bolstering the objective response rate of stable disease from 25% with carboplatin alone to 88% when paired with Fasnall.

ZN-A-1041 is an inhibitor of HER2 in BT474 cells with an IC50 of 9.5 nM and wt-EGFR in H838 cells with an IC50 of 12 μM. It can be utilized for cancer and inflammation research [1].

HVH-2930 is an inhibitor of Heat Shock Protein 90 (HSP90). It suppresses the cell viability of BT474 (Trastuzumab sensitive) and JIMT-1 (Trastuzumab resistant) by downregulating HSP90 client proteins such as HER2, p-HER2, AKT, p-AKT, cyclin D1, and survivin, with IC50 values of 6.86 μM and 4.42 μM, respectively. Additionally, HVH-2930 demonstrates antitumor efficacy in a mouse model and exhibits favorable pharmacokinetic properties in vivo.

BAZ1A-IN-1 is a potent BAZ1A inhibitor with a KD value of 0.52 μM for the BAZ1A bromodomain, demonstrating strong anti-survival activity against cancer cell lines with high BAZ1A expression and weak or no activity against cancer cells with low BAZ1A expression.
