(-)PPP Chemical Properties,Usage,Production

Description

Picropodophyllotoxin (477-47-4) is a potent and selective inhibitor of insulin-like growth factor 1 receptor (IGF1R) which is non-competitive with ATP.1?Displays no activity at IR, EGFR, FGFR or PDGFR. Inhibits IGF1R autophosphorylation IC50 ~ 1 nM.1?Displays antiproliferative activity in numerous tumor cell lines, IC50 = 0.05 – 15 μM.2 Exhibits antiangiogenic activity.3?Picropodophyllotoxin attenuates intimal hyperplasia after vascular injury.4?Active in vivo.

Uses

Insulin growth factor 1 receptor inhibitor, antineoplastic

Uses

Picropodophyllotoxin is an insulin-like growth factor-I (IGF-I) receptor kinase inhibitor

Definition

ChEBI: An organic heterotetracyclic compound that has a furonaphthodioxole skeleton bearing 3,4,5-trimethoxyphenyl and hydroxy substituents.

General Description

Poly(2,5-bis(3-sulfonatopropoxy)-1,4-phenylene, disodium salt-alt-1,4-phenylene) (PPP-OPSO3) is a water soluble conjugating polymer that can be used as a donor molecule. It has a poly(p-phenylene) skeleton with each repeating unit having two phenylene groups. It can be used for a variety of optoelectronic applications.

Biological Activity

Orally active insulin-like growth factor 1 receptor (IGF1R) inhibitor that exhibits no activity at the insulin receptor, FGFR, PDGFR or EGFR. Inhibits IGF1R autophosphorylation (IC 50 ~ 1 nM), increases the fraction of cells in the G 2 /M phase and upregulates apoptosis. Exhibits antiproliferative effects in multiple cancer cell lines (IC 50 = 0.05 - 15 μ M), and has anticancer and antineovascularization activity in vivo .

Biochem/physiol Actions

Picropodophyllotoxin (PPP), an epimer of podophyllotoxin (PPT), has been reported to target insulin-like growth factor-I receptor (IGF-IR) and mediate anticancer functions. However, a study in 2007, has reported that PPP can induce G2-M cell cycle arrest even in IGF-IR deficient cells. Hence, the role of PPP in IGF-IR-mediated anticancer functions is debatable.

storage

Store at +4°C
