Description: ZSTK474 is a novel orally applicable phosphoinositide 3-kinase-specific inhibitor that strongly inhibits cancer cell proliferation. Combination treatment using X-rays then ZSTK474 given orally for 8 days, starting 24h post-irradiation, significantly enhanced cell growth inhibition. The combined effect was also observed for clonogenic survival with continuous ZSTK474 treatment. Western blot analysis showed enhanced phosphorylation of Akt and GSK-3β by X-irradiation, whereas phosphorylation was inhibited by ZSTK474 treatment alone. Treatment with ZSTK474 after X-irradiation also inhibited phosphorylation, and remarkably inhibited xenograft tumor growth.

Bulk inquiry Welcome, Customer: Please do not inquire quote if your intended use is for a patient since our products are for research use and for chemical synthesis use, not for human use . For in-stock products, we listed price in the web page. You may inquire prices for which sizes were not listed. If no price is listed, this means the product is not in stock at the moment, which may be available via custom synthesis. For cost-effective reason, minimum order of 1g is requested (typically very expensive). The lead time is usually 2-4 months. Quote of less than 1g will not be provided. MedKoo may not offer quote for below reasons: (1) current available synthetic method appears to be extremely expensive which is obviously not affordable to most customers; (2) Key raw material to make the product is temporally not available; (3) DEA controlled substances; (4) the product is under patent protection in customer’s country.

More Info: Z STK474 directly inhibited PI3K activity more efficiently than the PI3K inhibitor LY294002. At concentrations of 1 microM, ZSTK474 and LY2194002 reduced PI3K activity to 4.7% (95% confidence interval [CI] = 3.2% to 6.1%) and 44.6% (95% CI = 38.9% to 50.3%), respectively, of the untreated control level. Molecular modeling of the PI3K-ZSTK474 complex indicated that ZSTK474 could bind to the ATP-binding pocket of PI3K. ZSTK474 inhibited phosphorylation of signaling components downstream from PI3K, such as Akt and glycogen synthase kinase 3beta, and mediated a decrease in cyclin D1 levels. ZSTK474 administered orally to mice had strong antitumor activity against human cancer xenografts without toxic effects in critical organs. Akt phosphorylation was reduced in xenograft tumors after oral administration of ZSTK474. CONCLUSION: ZSTK474 is a new PI3K inhibitor with strong antitumor activity against human cancer xenografts without toxic effects in critical organs. ZSTK474 merits further investigation as an anticancer drug. (source: J Natl Cancer Inst. 2006 Apr 19;98(8):545-56.)
