Protocol

Cell experiment [1, 2]:

Cell lines

NSCLC cells lines (A549, H460, H1975, PC14, H1299, and H23); MiaPaCa-2 and L3.6pl cells

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

1.0 μmol/L for 24h; or 0.1-1.0 μmol/L

Applications

KPT-330 inhibited proliferation, induced cell cycle arrest and apoptosis-related proteins in 11 NSCLC cells lines (A549, H460, H1975, PC14, H1299, and H23). Moreover, KPT-330 (0.1-1.0 μmol/L) dose-dependently inhibited the growth of MiaPaCa-2 and L3.6pl cells.

Animal experiment [1, 2]:

Animal models

Human NSCLC H1975 tumor xenograft model; human metastatic pancreatic cancer cells are orthotopically injected into the pancreas of mice model

Dosage form

10 mg/kg, oral treatment, thrice weekly for 4 weeks; or 10, 20 mg/kg p.o., 3/week

Applications

KPT-330(10 mg/kg) showed antitumour activity against human non-small cell lung cancer. Moreover, KPT-330 potentiated the antitumor activity of gemcitabine in human pancreatic cancer through inhibition of tumor growth, induction of apoptosis, and depletion of the antiapoptotic proteins.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

P276-00 is a novel inhibitor for CDK-1, CDK4 and CDK9 with IC50 of 79 nM, 63 nM and 20 nM, respectively [1].
CDK (cyclin-dependent kinase) plays an important role in cell cycle progression via promoting the G1/S cell cycle transition. Many studies have shown that more CDKs are overexpressed in cancer cells than in normal cells, which explain the reason of cancer cells divide uncontrollably[2]. The overexpression of CDK1/4/6 contributes to the phosphorylation of retinoblastoma protein (RB) via binding to CCND1 and results in the release of E2F transcription of genes required for cell cycle progression [3].
P276-00 is a novel inhibitor of CDK (cyclin-dependent kinase) with the ability of arresting the cells in G1/S phase transcription. When tested with NSCLC cell lines, P276-00 showed high ability of inhibiting cell proliferate thus decreased the colony forming potential via blocking cell cycle [4]. In head and neck squamous carcinoma cell line (FaDu, Detroits-562, SCC-25), treated with P276-00 for 12 hours could significantly inhibit cell ability with IC50 value ranging from 0.8 to 1.7 uM for different cell lines via decreasing the expression of CCND1[2].
In SCID mice model with H460 xenograft, treatment of P276-00 could down regulate the expression of CDK1 thus induced tumor regression [4]. When tested with HNSCC tumor xenograft mouse model, P276-00 treatment showed anti-cancer ability with a 48% tumor growth inhibition [2].
