Disitertide

Disitertide (P144) is a peptidic transforming growth factor-beta 1 (TGF-β1) inhibitor specifically designed to block the interaction with its receptor. Disitertide (P144) is also a PI3K inhibitor and an apoptosis inducer.

How to use

In Vitro:

Disitertide (100 μg/mL) suppresses the protein expression levels of PI3K and p-Akt, and induce the protein expression of Bax in MC3T3-E1 cells. Disitertide (TGF-β1 inhibitor) abrogates the MACC1- AS1 expression in GC cells, suggesting that targeting TGFβ signaling pathway may be a potential strategy to inhibit MSC-induced stemness and chemoresistance. Disitertide (P144, 10 μg/mL to 200 μg/mL) affects proliferation, induces apoptosis as well as anoikis in A172 and U-87 MG GBM cell lines.

In Vivo:

Disitertide (Topical application, 300 μg/mL) may promote scar maturation and clinical improvement of hypertrophic scar morphology features in an “in vivo” model in nude mice after two weeks of treatment.
