Description

In Vitro

Alpelisib (BYL-719) potently inhibits the 2 most common PIK3CA somatic mutations (H1047R, E545K; IC₅₀s~4 nM). Alpelisib potently inhibits Akt phosphorylation in cells transformed with PI3Kα (IC₅₀=74±15 nM) and shows significant reduced inhibitory activity in PI3Kβ or PI3Kδ isoforms transformed cells (≥15-fold compared with PI3Kα)^[2].
Alpelisib (BYL-719, 0-50 μM; 72 hours) inhibits the cell growth of osteosarcoma cell lines MG63, HOS, POS-1 and MOS-J in a dose-dependent manner^[3].
Alpelisib (BYL-719) significantly alters the distribution of cell cycle phases. Alpelisib (BYL-719, 25 μM; 18 hours) induces a cell cycle arrest in the G0/G1 phase of human and murine osteosarcoma cell lines^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Alpelisib (BYL-719) (12.5 mg/kg and 50 mg/kg for C57Bl/6J mice; 50 mg/kg for female Rj:NMRI-nude mice; oral administration; daily) significantly reduces tumor volumes and deposition of ectopic bone matrix^[3].
Alpelisib has moderate terminal elimination half-life (t_1/2=2.9±0.2 h) for rat (1 mg/kg, iv)^[1].

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
