What is ZPCK?

Description

SL-01 (26049-94-5) inhibits the p53-MDM2 interaction (20 μM). Has also been shown to inhibit bovine chymotrypsin A-γ.

Chemical properties

white powder

The Uses of ZPCK

ZPCK's a peptidase from baker's yeast,and it is with esterase activities of carboxypeptidase Y.

The Uses of ZPCK

SL 01 is a prodrug of gemcitabine , the nucleoside analog used intravenously to treat various cancers that was designed for improved oral bioavailability. SL 01 can inhibit the growth of human non-small cell lung cancer NCI-H460 cells, colon cancer HCT-116 cells, and breast cancer MCF-7 cells (IC50s = 0.78, 0.92, and 0.64 μM, respectively), inducing apoptosis. In nude mice bearing NCI-H460, HCT-116, or MCF-7 cancer cell xenografts, SL 01 at 10-50 μM/kg has been shown to delay tumor growth.

The Uses of ZPCK

Enzyme inhibitor.
