AES-350 is a potent and orally active HDAC6 inhibitor with an IC₅₀ and a K_i of 0.0244 μM and 0.035 μM, respectively. AES-350 is also against HDAC3, HDAC8 in an enzymatic activity assay with IC₅₀ values of 0.187 μM and 0.245 μM, respectively. AES-350 triggers apoptosis in AML cells through HDAC inhibition and can be used for acute myeloid leukemia (AML) research^[1].

In contrast, AES-350 has submicromolar activity (IC₅₀=0.58±0.13 μM) against MV4-11 cells than to that of vorinostat (IC₅₀=0.31±0.061 μM). AES-350 is more ligand efficient and exemplifies a large therapeutic index (IC₅₀>30 μM in noncancerous MRC-9 cells). AES-350 is also shown to be effective in AML-3 (acute myeloid leukemia) cells (IC₅₀=0.73 ± 0.12 μM)^[1].
AES-350 (0.25-4 μM; 18 hours) induces MV4-11 cells apoptosis in a dose-dependent manner. The late apoptosis ratios are 8.74%, 11.7%,16.08%, 30.97%, and 38.48%, respectively at 0.25 μM-4 μM^[1].
An ELISA is performed using HeLa cervical cancer cell lysates, and HeLa cells highly express HDAC6 and are sensitive to AES-350. Correspondingly, ELISA assays depicted a dose-dependent increase in HDAC6 inhibition (IC₅₀=0.58±0.13 μM), Western blot analysis shows that AES-350 (0.1-10 μM) induces a dose-dependent increase in acetylated α-tubulin (Ac-α-tubulin), a substrate of HDAC^[1].

AES-350 (oral gavage; 20 mg/kg; single dose) exhibits a relative good pharmacokinetic (PK) properties in CD-1 mice. The single dose oral bioavailability (F%) of 51 is 19.8%. In comparison, the reported F% for SAHA in mice is significantly lower (8%)^[1].

NSG mice are dosed with a single 20 mg/kg intraperitoneal (IP) injection, and blood is taken at 0.5 h, 1 h, 2 h, 4 h, 8 h, and 24 h. AES-135 achieved μM concentrations in the blood, reaching C_max 7452 ng/mL (10.74 μM) within 30 min, which is sustained for 8 h. The blood concentration of AES-135 is dose dependent, achieving an average of 323 ng/mL (0.47 μM) with 10 mg/kg dosing and 1829 ng/mL (2.64 μM) with 40 mg/kg. AES-135 shows an impressive pharmacokinetic profile in mice with an in vivo half-life of 5.0 h^[1].
