Hu7691 is an orally active, selective Akt inhibitor with IC50 s of 4.0 nM, 97.5 nM, 28 nM for Akt1, Akt2 and Akt3, respectively. Hu7691 inhibits tumor growth and enables decrease of cutaneous toxicity in mice [1].
In Vivo, Hu7691 (12.5-50 mg/kg/day; i.g.; for 22 days) shows dose-dependent tumor growth inhibition[1]. Hu7691 (15 mg/kg; oral) has a T1/2 of 8.68 hours, a Cmax of 171.17 ng/mL and an AUC of 2820.64 ng/mL h in rats[1]. Hu7691 (2 mg/kg; iv) has a T1/2 of 6.24 hours, a Cmax of 207.52 ng/mL and an AUC of 532.87 ng/mL h in rats[1]. Hu7691 (20 mg/kg; oral) has a T1/2 of 16.7 hours, a Cmax of 905.65 ng/mL and an AUC of 36303 ng/mL h in beagle dog (male, 40 weeks old, 8-10 kg)[1].
In Vitro, Hu7691 displays low inhibitions against most of the kinases in the four families (AGC, TK, TKL, Lipid/Atypical; PKA, IC50=11 nM; PKCη, IC50=629 nM; ROCK1, IC50=354 nM; RSK1, IC50=756 nM; P70S6K, IC50=229 nM; SGK, IC50=1009 nM)[1]. Hu7691 (2.25-36 μM; 24 hours) induces effective decrease of the phosphorylation level of Akt (S473)[1]. B5 (10, 20, 30, 40 μM; for 72 h) exhibits low toxicity against HaCaT cells with an IC50 value of 15.2 μM[1]. Hu7691 has a significant inhibitory effect on the growth of 18 kinds of human tumor cells (U87-MG, U251, A549, HepG2, HT-29, KHOS, MDA-MB-231, PC3, SKOV3 and so on) derived from different tissues, with the IC50 range of 0.6-27 μM. Hu7691 shows low antiproliferation activities against the HL7702 and HPDE6-C7 normal cells, exhibiting IC50 values of 5.4 and 16.1 μM, respectively[1].
