Bimiralisib (PQR309) 是一种有效的，可渗透脑的，PI3K/mTOR 抑制剂，抑制 PI3Kα, PI3Kδ, PI3Kβ, PI3Kγ 和 mTOR，IC₅₀ 分别为 33 nM，451 nM，661 nM，708 nM 和 89 nM。

Bimiralisib (PQR309) is a potent, brain-penetrant, orally bioavailable, pan-class I PI3K/mTOR inhibitor with IC 50 s of 33 nM, 451 nM, 661 nM, 708 nM and 89 nM for PI3Kα, PI3Kδ, PI3Kβ, PI3Kγ and mTOR, respectively. Bimiralisib is an mTORC1 and mTORC2 inhibitor.

Bimiralisib is a highly selective pan-PI3K inhibitor with a balanced targeting of mTOR kinase. Bimiralisib also inhibits PI3Kα-H1047R), PI3Kα-E542K and PI3Kα-E545K with IC50s of 36 nM, 63 nM and 136 nM, respectively. has not independently confirmed the accuracy of these methods. They are for reference only.

Oral administration yields similar concentrations of Bimiralisib in brain and plasma samples illustrates that Bimiralisib readily passes the blood–brain barrier. In mice, both po and iv application routes show a rapid drop below 200 ng/mL (~0.5 μM) of PQR309 within <1 h (iv) to <2 h (po) after administration, which reflects the time point when the drug reaches the median GI 50 determined in tumor cell lines. In female rats a single oral dose (10 mg/kg) achieves similar drug levels as a single intravenous injection (5 mg/kg) with regard to C max . The half-life of 5-8 h and an AUC 0.25-12 of around 14 000 h?ng/mL contributed to an excellent oral bioavailability of PQR309 (>50%). Twenty-four hours after po administration, plasma levels of PQR309 are still >2 μM (800-1000 ng/mL). Moreover, after 1-2 h exposure to PQR309 , drug levels in r
