| | ZSTK474 Usage And Synthesis |
| Description | ZSTK474 (475110-96-4) is a novel Class I phosphatidylinositol 3-kinase (PI3K) inhibitor. ZSTK474 is an ATP-competitive inhibitor of all four Class I PI3K isoforms. However, it inhibits PI3Kδ most potently, with a Ki of 1.8 nM, while inhibiting the α, β and γ isoforms at slightly higher concentrations (6.7 nM, 10.4 nM and 11.7 nM, respectively)1. Displays potent antitumor activity against human cancer xenografts (A549, PC-3 and WiDr) when administered to mice2. ZSTK474 displays potent anti-inflammatory activity via modulation of human CD14+ monocyte-derived dendritic cell functions and suppresses experimental autoimmune encephalomyelitis3. Ameliorates the progression of adjuvant-induced arthritis in a rat model4. | | Uses | ZSTK474 is a triazine derivative that acts as an inhibitor of class I phosphatidylinositol 3-kinase (PI3K) isoforms (IC50s = 17, 53, and 6 nM for p110β, -γ, and -δ, respectively). It is selective for PI3K, as it has negligible activity against 139 other kinases when tested at 30 μM. ZSTK474 is orally bioavailable and shows strong antitumor activity against human cancer xenografts in mice. The efficacy of ZSTK474 against certain cancer cells and tumors can be enhanced by combination therapy. | | Uses | ZSTK474 is an ATP-competitive inhibitor of class I phosphatidylinositol 3 kinase (PI3K) isoforms. Potent PI3K inhibitor. | | Definition | ChEBI: A triamino-1,3,5-triazine that is 1,3,5-triazine in which two of the hydrogens have been replaced by morpholin-4-yl groups while the third hydrogen has been replaced by a 2-(difluoromethyl)benzimidazol-1-yl group. It is an inhibitor of phosphatidylinositol
