BEZ235 is an imidazoquinoline derivative inhibiting both PI3K and mTOR kinases with low nanomolar IC50s. It was well tolerated in preclinical animal studies as well as in clinical trials with manageable gastrointestinal side-effects[1, 2]. It competes with ATP by binding to the ATP-binding site of kinases and reversibly reduces enzyme activity, resulting in growth arrest of tumor cells in G1 phase[1]. Besides the inhibition of cell growth, BEZ235 blocks VEGF-induced angiogenesis[3]. It may also inhibit DNA-PKcs[4].

BEZ235 has shown potential anti-tumor activity both in vitro and in vivo. It inhibited growth of multiple cancer cell lines independently of mutation status in PI3K pathway[5]. In xenograft mice models, it blocked PI3K signaling and showed antitumor activity[1, 5]. Combination study demonstrated that it enhances the efficacy of temozolomide[1].

Clinical data shows anti-tumor activity of BEZ235 treatment, especially in cancer patients with deregulated PI3K signaling pathway. This compound is currently under investigation in multiple clinical trials either as monotherapy or in combination with other agents.

Preparation method

The solubility of this compound in DMSO is

Reaction Conditions

500 nM, for cell cycle inhibition 200 nM, 16 hours for pRb decrease


Flow cytometric analysis of PI-stained T-ALL cells treated with BEZ235 for 16 hours documented an increase in G0/G1 phase cells and a concomitant decrease in S and G2-M phases in both MOLT-4 and CEM-R cell lines. A decrease in the amount of Ser807/811 pRb was detected in MOLT-4 and CEM-R cells treated with 200 nmol/L NVP-BEZ235 for 16 hours, whereas total pRb levels remained unchanged.

Animal experiment: [2]

Animal models

Female athymic nude-Foxn1nu mice injected with BT474-VH2 cells

Dosage form

Oral administration, 40 mg/kg, once daily for 21 days


The antitumor activity of BEZ235 was studied in a xenograft model derived from HER2-amplified BT474 breast cancer cells engineered to express either the H1047R hotspot mutation or the empty vector (pBABE). BEZ235 treatment resulted in suppressed tumor growth. The H1047R-overexpressing tumors responded better to the BEZ235 treatment when compared with mock controls.

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.
