PLK1-IN-10 (Compound 4Bb) is an orally active PLK1 PBD (polo-box domain) inhibitor. PLK1-IN-10 blocks the interaction of PLK1 with the cell division regulator protein 1 (PRC1) and decreases the protein expression of the CDK1-Cyclin B1 complex. PLK1-IN-10 reacts with glutathione (GSH) to increase cellular oxidative stress, ultimately leading to cell death.

In Vitro

PLK1-IN-10 (0-6 μM; 48 h) induces cell cycle arrest in the G2/M phase in A549 and A549/DDP cells, inhibiting cell proliferation^[1].
PLK1-IN-10 (20 μM) stabilizes PLK1 protein in A549/DDP cells across a range of temperatures^[1].
PLK1-IN-10 (5 μM; 24 h) reacts with GSH, producing a dose- and time-dependent fluorescent response, with higher fluorescence intensity in A549/DDP cells^[1].
PLK1-IN-10 (0-9 μM; 48 h) increases intracellular ROS levels in A549/DDP cells^[1].
PLK1-IN-10 (10 μM; 48 h) inhibits the interaction between PLK1 and PRC1, leading to the appearance of multinucleated cells^[1].
PLK1-IN-10 shows an anticancer activity of IC₅₀=7.83 μM against NCI-H1975 cells^[1].

Western Blot Analysis^[1]

Cell Line:

A549, A549/DDP
Concentration:

0, 1.5, 3, 6 μM
Incubation Time:

48 h
Result:

Downregulated the expression of PLK1, CDK1, Cyclin B1, as well as significantly downregulated the expression of the CDK1-Cyclin B1 complex and Cdc25 protein.

Cell Cycle Analysis^[1]

Cell Line:

A549, A549/DDP
Concentration:

0, 1.5, 3, 6 μM
Incubation Time:

48 h
Result:

Significantly increased the number of A549 and A549/DDP cells in the G2/M phase, inducing mitotic catastrophe.

In Vivo

PLK1-IN-10 (30, 50 mg/kg; i.p.; every two days for 32 days) significantly inhibits tumor growth in A549/DDP drug-resistant xenograft mice, with the 50 mg/kg group even causing tumor regression^[1].
PLK1-IN-10 (30 mg/kg; p.o.; every two days for 20 days) effectively inhibits tumor growth in NCI-H1975 drug-resistant xenograft mice^[1].

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

Animal Model:

A549/DDP drug-resistant xenograft mice^[1]
Dosage:

30, 50 mg/kg
Administration:

i.p.; once every two days for 32 days
Result:

TGI reached 42% for the 30 mg/kg group and 62% for the 50 mg/kg group.
Extended the median survival time from 38 days in the control group to 53 days in the 30 mg/kg group and 62 days in the 50 mg/kg group.
Had no significant impact on the body weight and major organs of the mice, except for a slight difference in heart index observed in the 30 mg/kg group.
Significantly reduced the number of Ki-67 positive cells in the tumor tissue.
Showed no significant differences in H&E staining of major organs, further confirming its good biosafety.

Animal Model:

NCI-H1975 drug-resistant xenograft mice^[1]
Dosage:

30 mg/kg
Administration:

p.o.; once every two days for 20 days
Result:

TGI reached 44%. Caused no harm to the body weight and major organs of the mice.

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.
