API-1 is a potent selective Akt/PKB inhibitor that reduces the level of phosphorylated Akt (IC₅₀ = 0.8 μM). API-1 binds to the PH domain and inhibits Akt membrane translocation. API-1 induces c-FLIP degradation. API-1 reduces cell proliferation and induces apoptosis. API-1 decreases tumor growth in mouse xenograft model.

API-1 (0.625-10 μM, 3 d) effectively inhibits the growth of non-small cell lung cancer (NSCLC) and head and neck squamous cell carcinoma (HNSCC) cell lines^[1].
API-1 (5-10 μM, 24 h) effectively induces apoptosis in API-1-sensitive NSCLC and HNSCC cell lines^[1].
API-1 (1.25-5 μM, 24 h) synergizes with factor-related apoptosis-inducing ligand (TRAIL) to induce apoptosis in H1229 and 22A^[1].
API-1 (0.625-10 μM, 2-24 h) reduces the levels of c-FLIP (through facilitating ubiquitin/proteasome-mediated degradation) without increasing the expression of DR4 or DR5 in NSCLC and HNSCC cells^[1].
API-1 (0.625-10 μM, 2-24 h) inhibits the phosphorylation of Akt in NSCLC and HNSCC cells^[1].
API-1 (0.5-20 μM, 12-72 h) induces GSK3-dependent, β-TrCP- and FBXW7-mediated Mcl-1 degradation, resulting in induction of apoptosis in NSCLC cell lines^[2].

Cell Proliferation Assay^[1]

Cell Line:

Human non-small cell lung cancer (NSCLC) cell lines (H157, Calu-1 and H1299) and head and neck squamous cell carcinoma (HNSCC) cell lines (22A, Tr146 and SqCC/Y1)
Concentration:

0.625, 1.25, 2.5, 5, 10 μM
Incubation Time:

3 d
Result:

Effectively inhibited the growth of 5 (H1299, H157, SqCC/Y1, 22A and Tr146) of 6 tested cancer cell lines.
The effective concentrations that decreased cell numbers by 50% (IC₅₀s) ranged between 2 and 5 μM for these sensitive cell lines.

Apoptosis Analysis^[1]

Cell Line:

H1299, Calu-1, SqCC/Y1
Concentration:

5, 10 μM
Incubation Time:

24 h
Result:

Dose-dependently increased annexin V-positive (or apoptotic) cells in H1299 and SqCC/Y1 cells (> 40% at 10 μM), but did so only minimally in Calu-1 cells (< 15% at 10 μM).
Dose-dependent increased cleavage of caspase-8, caspase-9, caspase-3 and PARP in H1299 and SqCC/Y1 cells, but this was not apparent in Calu-1 cells.

Apoptosis Analysis^[1]

Cell Line:

H1299, H157, Calu-1, SqCC/Y1, 22A, Tr146
Concentration:

1,25, 2.5, 5 μM; 5 μM (H1299, 22A)
Incubation Time:

24 h
Result:

Combination (5 or 2.5 μM) with TRAIL (25 to 100 ng/ml) was much more effective than either agent alone in decreasing the survival of the tested NSCLC and HNSCC cell lines, except for Calu-1 cells.
The CIs for these combinations were < 1.
Combination with TRAIL was much more potent than used alone in increasing cleavage of caspase-8, caspase-9, caspase-3 and PARP in H1229 and 22A.
Increased the proportion of annexin Vpositive cells in H1229 and 22A.

Western Blot Analysis^[1]

Cell Line:

H1299, H157, Calu-1, SqCC/Y1, 22A, Tr146
Concentration:

5 μM; 0.625, 1.25, 2.5, 5, 10 μM (H157)
Incubation Time:

24 h; 12 h (H157 with different concentrations); 2, 4, 8, 12, 16 h (H157 with concentration of 5 μM)
Result:

Reduced the levels of c-FLIP in H157, H1299, SqCC/Y1 and Tr146 cells, but not in Calu-1 cells at 5 μM.
Did not increase the expression of either DR5 or DR4 in any of the cell lines.
Reduced the levels of DR4 in some cell lines (H1299, SqCC/Y1 and Tr146).
Showed dose-course and time-course studies of the effects on the levels of c-FLIP, DR4 and DR5 in H157 cells.
The apparent reduction of c-FLIP in cells occurred after 4 h exposure.

In Vivo

API-1 (10 mg/kg; i.p.; daily for 6-8 weeks) selectively inhibits the growth of tumors with hyperactivated Akt in OVCAR3 and PANC-1 xenograft mice model^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

8-week-old female nude mice (implanted tumors with hyperactivated Akt (OVCAR3 and PANC-1) into the left flank and those tumors that express low levels of activated Akt (OVCAR5 and COLO357) into the right flank)^[3]
Dosage:

10 mg/kg
Administration:

Intraperitoneal injection (i.p.); daily for 6-8 weeks
Result:

Inhibited OVCAR3 and PANC1 tumor growth by 70 and 50%, respectively.
Had little effect on the growth of OVCAR5 and COLO357 cells in nude mice.
Had no effects on blood glucose level, body weight, activity, and food intake of mice.
Phosphorylation levels of Akt were reduced about 70% without a change of total Akt content.

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
