pi3kα/mtor-in-1

PI3Kα/mTOR-IN-1 is a potent dual inhibitor of PI3Kα/mTOR, with an IC50 of 7 nM for PI3Kα in a cell assay and Kis of 12.5 nM and 10.6 nM for mTOR and PI3Kα [in a cell-free assay], respectively.

PI3K/HDAC-IN-4 (Compound 31f) is a dual inhibitor targeting PI3K and HDAC, with an IC50 of 0.2μM. It demonstrates high selectivity for HDAC1-3, with IC50 values of 75.5 nM, 70.9 nM, and 1.9 nM, respectively. As a potent pan-PI3K inhibitor, PI3K/HDAC-IN-4 has IC50 values of 2.5 nM, 80.5 nM, 10.0 nM, and 57.2 nM for PI3Kα, β, δ, and γ, respectively. This compound effectively induces apoptosis in tumor cells by concurrently inhibiting the PI3K/AKT/mTOR signaling pathway and HDAC1-3. It shows significant antiproliferative activity across various tumor cell lines, such as MV4-11, Jeko-1, HL60, and MCF-7, with IC50 values of 0.2, 0.9, 0.8, and 1.5 μM, respectively. PI3K/HDAC-IN-4 is applicable in the study of lymphoma and leukemia.

DS-7423 is a dual PI3K and mTOR inhibitor, with IC50 values of 15.6 nM and 34.9 nM for PI3Kα and mTOR, respectively, and exhibits anti-tumor activity[1][2]. It increases TP53 expression, the level of p-TP53 on Ser-46, and induces apoptosis-related TP53 target genes (TP53AIP1 and PUMA) in OCCC cells[1]. DS-7423 also inhibits other isoforms of class I PI3K with IC50 values of 1,143 nM for PI3Kβ, 249 nM for PI3Kγ, and 262 nM for PI3Kδ[2]. [1]. Katsutoshi Oda, et al.

PI3Ka-IN-5 is a potent PI3Kα mTOR inhibitor, with an IC 50 of 0.7 nM and 3.3 nM, respectively. PI3Ka-IN-5 can be used for the research of colorectal cancer .

PI3Kα-IN-1 is an inhibitor specifically targeting PI3Kα with an IC50 of less than 0.5 nM, and it also inhibits mTOR with an IC50 of 104 nM [1].
