Lw13

Lw13 is a Hsp90 PROTAC degrader. Lw13 induces Hsp90 degradation via the ubiquitin-proteasome system, destabilizes client proteins HER2 and AKT, and blocks the activation of the HER2/AKT/mTOR signaling pathway. Lw13 inhibits the metastasis of cervical cancer cells, induces cell cycle arrest and apoptosis (apoptosis). Lw13 exerts synergistic anti-tumor activity with Cisplatin (HY-17394). Lw13 is applicable to cervical cancer-related research.

In Vitro

Lw13 (72 h) potently inhibits the proliferation of SiHa, HeLa, C33A and CaSki cervical cancer cells, with IC₅₀ values of 0.05, 0.08, 0.07 and 0.05 μM, respectively^[1].
Lw13 (0.01-1 μM; 4-48 h) degrades Hsp90 in a time- and dose-dependent manner in SiHa cervical cancer cells, with the degradation effect peaking at a concentration of 0.05 μM after 10 h of incubation^[1].
Lw13 (0.01-1 μM; 14 days) inhibits colony formation of SiHa cervical cancer cells in a concentration-dependent manner^[1].
Lw13 (0.01-1 μM; 24-48 h) inhibits the migration of SiHa cervical cancer cells^[1].
Lw13 (0.05-10 μM) acts synergistically with cisplatin to inhibit the proliferation of SiHa cervical cancer cells^[1].
Lw13 (0.01-1 μM) inhibits the activation of the HER2/AKT/mTOR signaling pathway in SiHa cervical cancer cells by reducing the protein levels of HER2 and AKT, as well as decreasing the phosphorylation of AKT and mTOR^[1].
Lw13 (0.05-10 μM; 48 h) induces concentration-dependent apoptosis in SiHa cervical cancer cells, with significant increases in both early and late apoptotic cell populations after 48 h of incubation^[1].
Lw13 (0.05-10 μM; 48 h) induces concentration-dependent G₂/M cell cycle arrest in SiHa cervical cancer cells after 48 h of incubation^[1].

In Vivo

lw13 (2 mg/kg; i.p.; every two days for 30 days) delivers potent tumor growth inhibition in a cervical cancer xenograft mouse model, reduces tumor cell proliferation via Ki67 downregulation, and enhances the antitumor activity of cisplatin without causing significant body weight loss^[1].

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

Animal Model:

BALB/c nude (female, 4 weeks old, subcutaneous cervical cancer xenograft model via injection of 5×10⁶ SiHa cells into right lower axilla, treatment initiated when tumor volume reached 100 mm³)^[1]
Dosage:

2 mg/kg
Administration:

i.p.; every two days for 30 days
Result:

Exhibited higher tumor growth inhibition (TGI) than cisplatin at the same dose.
Enhanced cisplatin's antitumor activity with a higher TGI index than either agent alone when combined with 2 mg/kg cisplatin.
Caused no significant body weight loss, indicating no overt toxicity.
Reduced Ki67 staining in tumor tissues compared to the control group, indicating decreased tumor cell proliferation.

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.
