CYH33 is an orally active, highly selective PI3Kα inhibitor with IC50s of 5.9 nM/598 nM/78.7 nM/225 nM against α/β/δ/γ isoform, respectively. CYH33 inhibits phosphorylation of Akt, ERK and induces significant G1 phase arrest in breast cancer cells and non-small cell lung cancer (NSCLC) cells. CYH33 has potent activity against solid tumors[1][2][3].
CYH33 inhibits cell proliferation with IC50s below 1?μM in 56% (18/32) of the breast cancer cell lines[2].
CYH33 (0.012-1 μM; for 24 hours) significantly arrests T47D and MCF7 cells in G1 phase in a concentration-dependent manner[2].
CYH33 (4-1000 nM; 1 hour) concurrently inhibits phosphorylation of ERK and Akt in both T47D and MCF7 cells[2].
CYH33 (0.11-1 μM; 24 hours) fails to induce apoptosis in MCF7 and MDA-MB-231?cells[2].
Cell Cycle Analysis[2]
| Cell Line: | Sensitive T47D, MCF7 and resistant MDA-MB-231 cells |
| Concentration: | 0.012, 0.037, 0.11, 0.33, 1 μM |
| Incubation Time: | For 24 hours |
| Result: | Arrested T47D and MCF7 cells in G1 phase in a concentration-dependent manner, accompanied with concomitant reduced cell population in S phase. Had little effect on cell cycle distribution in resistant MDA-MB-231?cells. |
Western Blot Analysis[2]
| Cell Line: | Sensitive T47D, MCF7 and resistant MDA-MB-231 cells |
| Concentration: | 4, 12, 37, 111, 333, 1000 nM |
| Incubation Time: | 1 hour |
| Result: | Concurrently inhibited phosphorylation of ERK and Akt in both T47D and MCF7 cells, whereas it had little effect on phosphorylated ERK (pERK) in MDA-MB-231?cells up to 1?μM. |
CYH33 (2-20 mg/kg; oral; once a day for 21 days) potently restrains tumor growth in mice bearing human breast cancer cell xenografts[2].
Single administration of CYH33 (20?mg/kg; oral) significantly down-regulates the level of phosphorylated Akt in tumor tissues, demonstrating the suppression of PI3K signaling in nude mice[2].
CYH33 (10?mg/kg; oral; once a day for 18-d or 20-d respectively) delays the restoration of blood glucose and area under the curve (AUC) of blood glucose increased upon CYH33 treatment in T47D xenografts and R26-Pik3caH1047R;MMTV-Cre mice[2].
| Animal Model: | SCID mice aged 4-6 weeks bearing human breast cancer T47D xenografts[2] |
| Dosage: | 2, 5, 10, 20 mg/kg |
| Administration: | Oral; once a day for 21 days |
| Result: | Displayed marginal inhibitory effect on the tumor growth at lower doses (2 and 5?mg/kg) and significantly attenuated tumor growth at the dose of 10 or 20?mg/kg, yielding T/C values of 58.36% and 49.42% respectively. |
