Cell experiment: | MTT and CCK-8 assays are performed to determine the general sensitivities of cells to the tested drugs. The human colon carcinoma S1 cell line and ABCG2-overexpressing subline S1-M1-80 are treated with PF-4989216 (0.1, 1 and 10 μM). The human breast carcinoma MCF-7 and ABCG2-overexpressing sublines MCF7-FLV1000 and MCF7-AdVp3000 are treated with PF-4989216 (0.1, 1, 10 and 100 μM).The parental HEK293 and ABCG2-tranfected R482-HEK293 cells are treated with PF-4989216 (0.01, 0.1, 1 and 10 μM). For the reversal of cytotoxicity assays, PF-4989216 or Ko143 or Lapatinib at a nontoxic concentration is added into the cytotoxicity assay, and the extent of reversal is then calculated[2]. |
Animal experiment: | Mice[1]For animal studies, 6-8 week old nu/nu athymic female mice are used. Tumors are established by injecting 2×106 cells suspended 1:1 (v/v) with reconstituted basement membrane. For tumor growth inhibition studies, mice with established tumors of ~150 mm3 are randomized. PF-4989216 (Compound 10) is dosed orally (25, 50, 100 and 200 mg/kg) in a mouse PI3K driven NCI-H1975 xenograft tumor model. Tumor dimensions are measured with vernier calipers, and tumor volumes are calculated. Tumor growth inhibition percentage (TGI %) is calculated. |

Description:
IC50: 2 nM, 142 nM, 65 nM, 1 nM, and 110 nM for p110α, p110β, p110γ, p110δ, and VPS34, respectively.
The constitutive activation of phosphoinositide 3-kinase (PI3K) occurs frequently in many human tumors through either gene mutation in the p110a catalytic subunit of PI3K or functional loss of tumor suppressor PTEN. Patients with small-cell lung cancer have very poor prognosis and survival rates such that an effective targeted therapy is in strong demand for these patients. PF-4989216 is a selective oral PI3K inhibitor.
In vitro: PF-4989216 inhibited PI3K downstream signaling and led to apoptosis induction, and inhibition in cell viability, transformation, and xenograft tumor growth in small-cell lung cancer (SCLC) harboring PIK3CA mutation. In SCLC with PTEN loss, PF-4989216 also inhibited PI3K signaling but did not induce BCL2-interacting mediator-mediated apoptosis nor was there any effect on cell viability or transformation [1].
In vivo: The mouse in vivo results indicate a good correlation between in vitro and in vivo efficacy, and further confirm that PF-4989216 is an effective drug candidate capable of inducing antitumor activity in mice bearing human SCLC tumors with PIK3CA mutation [1].
Clinical trial: Up to now, PF-4989216 is still in the preclinical development stage.
