Tyrphostin AG17

Tyrphostin AG17 is an orally active CDK2 inhibitor and EGFR tyrosine kinase antagonist. Tyrphostin AG17 reduces the levels of p21 and p16. Tyrphostin AG17 induces G1 phase cell cycle arrest, Apoptosis, mitochondrial dysfunction, decreased ATP levels, and inhibits DNA, RNA and protein synthesis, adipogenesis, and lipid synthesis. Tyrphostin AG17 inhibits fat accumulation, white adipose tissue hypertrophy, and alterations of glycogen and lipid inclusions in hepatocytes in obese mice without changing their serum biochemical parameters. Tyrphostin AG17 exhibits anticancer effects. Tyrphostin AG17 can be used in research related to immunoblastic lymphoma, leukemia, ovarian cancer, glioblastoma, colon cancer, breast cancer, melanoma, obesity and hepatic steatosis.

In Vitro

Tyrphostin AG17 (0.5-50 μM; 24 h) potently inhibits DNA synthesis in OCI-Ly8 immunoblastic lymphoma cells, with nearly complete inhibition observed at a concentration of 5 μM, and exhibits the strongest efficacy among the 16 tested tyrosine phosphorylation inhibitors^[1].
Tyrphostin AG17 does not alter the intracellular ATP level of OCI-Ly8 immunoblastic lymphoma cells^[1].
Tyrphostin AG17 reduces global protein tyrosine phosphorylation in a reversible or irreversible manner depending on the exposure mode, and decreases p21 and p16 protein levels in OCI-Ly8 immunoblastic lymphoma cells without altering Bcl-2 or cdk2 protein levels^[1].
Tyrphostin AG17 potently reduces cdk2 kinase activity in OCI-Ly8 immunoblastic lymphoma cells without altering cdk2 protein levels^[1].
Tyrphostin AG17 (6 days) inhibits the growth of tumor cell lines, with a GI₅₀ value ranging from 0.7 to 4.0 μM after 6 days of continuous treatment. Among these cell lines, HL-60 (TB) cells are the most sensitive (GI₅₀ = 0.7 μM, TGI = 1.5 μM)^[2].
Tyrphostin AG17 (2 μM; 2-24 h) rapidly reduces intracellular ATP levels in HL-60 (TB) cells, decreasing ATP levels by 50% within 2 h of exposure and by 85% within 24 h of exposure^[2].
Tyrphostin AG17 (1 μM) potently inhibits the differentiation and lipid accumulation of 3T3-L1 preadipocytes^[3].

Cell Viability Assay^[1]

Cell Line:

OCI-Ly8 immunoblastic lymphoma cells
Concentration:

0.5 μM (daily treatment for 5 consecutive days); 1 μM (single treatment); 5 μM (single treatment, two treatments with the second dose administered 3 days after the first)
Incubation Time:

single treatment (assessed over up to 9 days); two treatments (assessed over unspecified time); daily treatment for 5 consecutive days (assessed over unspecified time)
Result:

Did not cause significant cell death with a single 1 μM dose.
Arrested cell growth for 7 days with a single 5 μM dose, with growth recovery starting on day 9.
Resulted in cell death with two 5 μM doses (with the second given 3 days after the first).
Caused cells to grow slightly slower than controls for the first 3 days, followed by rapid cell death with daily 0.5 μM doses for 5 consecutive days.

Western Blot Analysis^[1]

Cell Line:

OCI-Ly8 immunoblastic lymphoma cells
Concentration:

0.5 μM (daily treatment for 5 consecutive days); 5 μM (single treatment, two treatments)
Incubation Time:

single 5 μM dose (analyzed at 1, 3, 10, 12 days); two treatments (analyzed at unspecified time); daily 0.5 μM doses for 5 days (analyzed at unspecified time)
Result:

Reduced global protein tyrosine phosphorylation with a single 5 μM dose, with a detectable effect at 1 day, dramatic reduction at 3 days, and full recovery by 12 days.
Caused permanent tyrosine dephosphorylation concurrent with apoptosis with multiple exposures.
Had no effect on Bcl-2 or cdk2 protein levels.
Caused marked reductions in p21 and p16 protein levels following both dual 5 μM doses and daily 0.5 μM doses for 5 days.

Cell Proliferation Assay^[2]

Cell Line:

HL-60(TB), K-562, Molt-4, SR, Ovcar-3, SNB-19, Colo 205, HCT-116, HS 578T, MCF-7, SK-MEL-5, A498, HOP-92
Concentration:

Unclear
Incubation Time:

Result:

Inhibited growth across all 13 cell lines, with GI₅₀ values ranging from 0.7 μM (HL-60(TB)) to 4.0 μM (MCF-7).
Exhibited TGI values ranging from 1.5 μM (HL-60(TB)) to 39.0 μM (SNB-19).
Showed steep concentration-effect curves for most cell lines, with GI₅₀ and TGI values spanning 1-6 μM, except for SNB-19, MCF-7, and A498 which had significantly higher TGI values (P < 0.05).

In Vivo

Tyrphostin AG17 (0.175 mg/kg; p.o.; daily; 2 weeks) induces adipocyte apoptosis and reduces WAT adipocyte size in diet-induced obese C57BL/6 mice, while shifting hepatic steatosis from macrovesicular to microvesicular alongside increased lipid inclusions without causing body weight loss^[3].
Tyrphostin AG17 (1.75-55.5 mg/kg; p.o.; single dose) has an LD₅₀ of 33.3 mg/kg in C57BL/6 mice, with transient behavioral effects at doses ≤17.5 mg/kg, 60% mortality at 40 mg/kg, 100% mortality at 28 mg/kg and 55.5 mg/kg, morphological changes in brain, kidney, liver, pancreas, and WAT at doses ≥17.5 mg/kg, and no changes in key serum biochemical markers in survivors, while skeletal muscle remains unaltered^[3].

Help & FAQs

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.
