Description: Miransertib, also known as ARQ 092, is an oral activie, potent and selective AKT inhibitor with IC50 values: 5.0 nM (AKT1); 4.5 nM (AKT2); 16 nM (AKT3). ARQ 092 binds to and inhibits the activity of AKT in a non-ATP competitive manner, which may result in the inhibition of the PI3K/AKT signaling pathway. This may lead to the reduction in tumor cell proliferation and the induction of tumor cell apoptosis. ARQ-092 demonstrated high enzymatic potency against AKT1, AKT2, and AKT3, as well as potent cellular inhibition of AKT activation and the phosphorylation of the downstream target PRAS40. ARQ-092 also served as a potent inhibitor of the AKT1-E17K mutant protein and inhibited tumor growth in a human xenograft mouse model of endometrial adenocarcinoma.

Biological target: Masupirdine free base (SUVN-502 free base) is a potent, selective, orally bioavailable, and brain penetrant 5-HT6 receptor antagonist (Ki of 2.04 nM for human 5-HT6 receptor).
In vitro activity: To determine the inhibitory effect of Miransertib on Leishmania growth, its effect on promastigotes of L. amazonensis and L. donovani was studied. First, promastigotes of L. amazonensis were treated with various concentrations of Miransertib for 24 hours. The number of viable parasites was determined by MTT assays. Fig 1 shows that increasing concentrations of Miransertib results in death of Leishmania parasites. The EC50 of Miransertib on L. amazonensis was estimated at 7.87 ± 0.93 μM (Fig 1A). For comparison, the EC50 of miltefosine on L. amazonensis was estimated at 40.83 ± 5.03 μM. The efficacy of Miransertib on L. donovani parasites was also determined to be 12.75 ± 1.14μM which was similar to the EC50 of miltefosine on L. donovani, which was 10.54 ± 3.51 μM (Fig 1B). These results show that Miransertib is as effective as miltefosine in killing L. donovani promastigotes, but it is slightly more effective on L. amazonensis promastigotes as compared to miltefosine.

In vivo activity: For in vivo efficacy of Miransertib, groups of L. donovani infected BALB/c mice (seven days post infection with stationary phase promastigotes) were dosed daily, for five consecutive days per week with an oral formulation of Miransertib (50 and 75 mg/kg). On day 28 post-infection, the parasite burdens in the livers and spleens of infected mice were quantified. The only available FDA approved oral anti-leishmanial drug miltefosine (20 mg/kg, once daily, 5 days per week) was included as a positive control. Both Miransertib and miltefosine were well tolerated at both doses throughout the study, with no mice displaying any overt signs of toxicity. The results show that Miransertib effectively suppressed parasite burdens by 80–90% (Fig 3A and 3B). In fact, at 50 and 75 mg/kg, Miransertib effectively cured 50% of the study mice (2/4 mice in both treatment groups), with no detectable parasites in the livers and spleens. 50 and 75 mg/kg doses of Miransertib compared favorably with miltefosine in the spleen (Fig 3A), whereas it was more active than miltefosine in the liver (Fig 3B). These results show that Miransertib has potent anti-leishmanial activity in vivo against L. donovani.

ARQ 092 was identified through this screening paradigm following in vitro and in vivo optimization and was selected for further development. Crystallographic studies provided evidence that this mechanism of inhibition of AKT had been achieved. ARQ 092 binds to inactive, unphosphorylated AKT1 with sub-nanomolar affinity (Kd = 0.28 nM measured by surface plasma resonance) and biochemically inhibits all three isoforms (IC50 values of 3 nM, 4.5 nM, and 5.5 nM respectively for AKT1, AKT2, and AKT3). ARQ 092 displayed inhibition kinetics against AKT1 which were not affected by ATP concentrations up to 1000 M. When screened against a panel of over 300 kinases, ARQ 092 inhibited only three kinases within 100-fold of its IC50 against AKT1. ARQ 092 potently inhibited AKT phosphorylation (Ser473 & Thr308) in AN3CA human endometrial carcinoma cells (EC50 values of 39 nM and 61 nM, respectively for p-Ser473 & p-Thr308) and demonstrated concentration-dependent inhibition of phosphorylation of the downstream AKT substrate PRAS40. ARQ 092 inhibited growth of AN3CA cells (GI50 = 555 nM), A2780 cells (GI50 = 400 nM), and IGROV-1 cells (GI50 = 66 nM), in addition to LNCaP, ZR-75–1, and BT-474 human cancer cell lines (GI50 values ranging from 1 to 4 μM). Following a single oral dose of ARQ 092, inhibition of AKT and PRAS40 phosphorylation was documented in vivo in both AN3CA human endometrial tumor and BT474 human breast tumor xenograft models. The growth of AN3CA tumor xenografts was markedly suppressed after daily oral administration of ARQ 092 for 10 days. Finally, ARQ 092 was shown to have good pharmaceutical properties and was advanced into preclinical development.   (source: Proceedings of the AACR-NCI-EORTC International Conference: Molecular Targets and Cancer Therapeutics; 2011 Nov 12-16; San Francisco, CA.
