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 (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].
