Description

HS-173 is a potent PI3Kα inhibitor with potential anticancer activity. HS-173 inhibited the PI3K signaling pathway, and showed anti-proliferative effects on cancer cells. Also, HS-173 induced cell cycle arrest at the G(2)/M phase and apoptosis. In addition, HS-173 decreased the expression HIF-1α and VEGF which play an important role in angiogenesis. This effect was confirmed by the suppression of tube formation and migration assay in vitro. Furthermore, HS-173 diminished blood vessel formation in the Matrigel plug assay in mice. Therefore, HS-173 is considered as a novel drug candidate to treat cancer patients.

How to use

In Vitro:

HS-173 (0.1-10 μM) reduces the cell viability in a dose- and time-dependent manner. HS-173 shows a significant drug response by the inhibition of colony formation in pancreatic cancer cells dose-dependently. HS-173 inhibits TGF-β-induced cell migration and invasion in pancreatic cancer cells. HS-173 suppresses TGF-β-induced epithelial mesenchymal transition (EMT). HS-173 treatment reduces cell viability in two hepatic stellate cell lines in a dose and time dependent manner. HS-173 induces cell cycle arrest in the G2/M phase. HS-173 treatment increases the expression of cleaved caspase-3 and decreased that of Bcl-2 in the HSC-T6 cells. HS-173 inhibits the expression of profibrotic mediators and ECM degradation modulators in HSCs[2]. The combination of Sorafenib and HS-173 synergistically inhibits cell proliferation in pancreatic cancer cell lines. The combination of Sorafenib and HS-173 inhibits key enzymes in both RAF/MAPK and PI3K/AKT signaling pathways.

In Vivo:

HS-173 (10 mg/kg, i.p.) significantly increases expression of TUNEL, cleaves caspase-3 along with decreased expression of PCNA in tumor tissues. HS-173 treatment decreases p-AKT and p-Smad2 in tumor tissues. HS-173 (10 and 30 mg/kg) significantly decreases the metastatic burdens on the lung and liver. HS-173 (10 and 20 mg/kg) inhibits ECM accumulation and PI3K/Akt signaling in mice with CCl4-induced liver fibrosis animal model. HS-173 clearly suppresses the expression of p-Akt and p-P70S6K along with decreasing expression of collagen I and vimentin in the mice with CCl4-induced liver fibrosis.
