PROTAC PI3Kα degrader-1
Based on 1 Customer Validation
PROTAC PI3Kα degrader-1 is a PI3Kα PROTAC degrader (DC50 = 0.08 μM), demonstrating good selectivity for PI3Kα degradation over PI3Kβ, PI3Kγ, and PI3Kδ. PROTAC PI3Kα degrader-1 effectively degrades PI3Kα in a time- and concentration-dependent, over PI3Kβ, PI3Ky and PI3Kδ, and potently inhibited the phosphorylation of AKT at the Ser473site. PROTAC PI3Kα degrader-1 shows significant in vivo anticancer efficacy in HGC-27 and DOHH2 xenograft models.
(Pink: PI3Kα ligand (HY-174798); Blue: Cereblon ligand (HY-10984); Black: linker).

PROTAC PI3Kα degrader-1 (Compound 12) (1 μM) shows negligible activity against 79 kinases (< 20% inhibition) while exhibits potent inhibition of PIK3CA (＞ 95%) in T47D breast cancer cells[1].
PROTAC PI3Kα degrader-1 (0.1-10 μM) demonstrates good selectivity for PI3Kα degradation over PI3Kβ, PI3Kγ and PI3Kδ in T47D breast cancer cells[1].
PROTAC PI3Kα degrader-1 exhibits excellent selectivity for the degradation of PI3Kα in various cancer cell lines, with IC50s of 0.35 μM (T47D), 1.64 μM (MDA-MB-453), 1.45 μM (HGC-27), 0.37 μM (AGS), 3.38 μM (LNCaP), 1.48 μM (PC3) and 0.69 μM (Pfeiffer)[1].
PROTAC PI3Kα degrader-1 (0.0032-10 μM, 0-24 h) degrades PI3Kα in a concentration- and time-dependent manner in T47D and HGC-27 cells[1].
PROTAC PI3Kα degrader-1 (1 μM, 20 h) degrades PI3Kα via the ubiquitin-proteasome pathway through CRBN recruitment in T47D cells[1].
PROTAC PI3Kα degrader-1 (0.1-10 μM, 24 h) induces cell cycle arrest at the G2/M phase concentration-dependently in T47D cells[1].

-
Cell Line:T47D cells
-
Concentration:1 μM
-
Incubation Time:20h with/without MG132 (HY-13259) (1 μM)
-
Result:Reduced the level of PI3Kα, while the addition of MG132 restored PI3Kα levels.
-
Cell Line:T47D cells
-
Concentration:1 μM
-
Incubation Time:24 h
-
Result:Did not decrease the mRNA levels of PIK3CA.
-
Cell Line:T47D cells
-
Concentration:1 μM
-
Incubation Time:8 h after Thalidomide (HY-14658) (10 μM) preincubated 1h and then incubated in fresh medium for an additional 48 hours.
-
Result:Degraded PI3Kα but preincubation with thalidomide (10 μM, 1 h) reduced this degradation.
Restored PI3Kα expression to normal levels 48 h after an 8h treatment followed by incubation in fresh medium.
PROTAC PI3Kα degrader-1 (Compound 12) (2 μM, 0-60 min) shows superior plasma stability across all of the tested species including mice, rats, dogs, monkeys, and human[1].
PROTAC PI3Kα degrader-1 (2 μM, 0-60 min) exhibits moderate to high clearance rates in each species,with half-life (t1/2) values of 22.6 min (mouse), 45.7 min (rat), 67.6 min (dog), 32.5 min (monkey), and 34.7 min (human), which is heavily dependent on NADPH[1].
PROTAC PI3Kα degrader-1 (30-60 mg/kg, i.p., daily for 14 days) demonstrates significant anticancer efficacy in the HGC-27 xenograft model[1].
PROTAC PI3Kα degrader-1 (30 mg/kg, i.p., daily for 21 days) exhibits potent antitumor activity in the DOHH2 xenograft model[1].
