PI3Kβ
PI3Kβ is a class I PI3K catalytic isoform that produces PIP3, linking receptor inputs to signaling networks that regulate cell growth, survival, and movement[1]. Mechanistically, PI3Kβ uniquely supports synergistic PIP3 formation when GPCR and RTK pathways are coactivated in myeloid cells, whereas p110α, p110β, and p110δ show partial redundancy downstream of M-CSF alone and p110γ acts nonredundantly downstream of C5a alone[1]. In PTEN-deficient breast tumour models, PI3Kβ inactivation reduced STAT3 signaling, increased immune-stimulatory molecules, and promoted anti-tumour immune responses[2]. Compared with related PI3K isoforms, this evidence positions PI3Kβ as a context-specific integrator of coincident receptor signaling and a disease-relevant driver in PTEN-null tumours[1][2]. For experimental applications, the PI3Kβ-selective inhibitor KIN-193 blocked AKT signaling and tumour growth dependent on p110β activation or PTEN loss, while pharmacological PI3Kβ inhibition also synergized with immunotherapy in PTEN-null breast tumour models[3][2].

Izorlisib methanesulfonate
0 ImagesCat. No.: HY-15466ACAS No.: 2242053-82-1Synonyms: CH5132799 methanesulfonateIzorlisib (CH5132799) methanesulfonate is an orally active, selective Class I PI3K inhibitor with an IC50 value of 14 nM against PI3Kα. Izorlisib methanesulfonate specifically inhibits Class I PI3K (particularly PI3Kα and its mutants) and blocks the PI3K/Akt/mTOR pathway; this leads to cell cycle arrest at the G1 phase and apoptosis without triggering feedback activation of Akt by competitively binding to the ATP-binding site of PI3K. Izorlisib methanesulfonate can be used in research on cancers harboring PIK3CA mutations or PTEN loss (such as breast, ovarian, prostate, and endometrial cancers).
