GW779439X，吡唑并吡啶类化合物，是一种金黄色葡萄球菌 PASTA 激酶 Stk1 抑制剂。GW779439X 增强 β-内酰胺类抗生素对各种 MRSA 和 MSSA 的分离株，有的甚至跨越了从耐药到敏感的断点。GW779439X 是一种 AURKA 抑制剂，可通过 caspases 3/7 诱导细胞凋亡 (apoptosis)。 GW779439X is a pyrazolopyridazine identified in an inhibitor of the S. aureus PASTA kinase Stk1. GW779439X potentiates the activity of β-lactam antibiotics against various MRSA and MSSA isolates, some even crossing the breakpoint from resistant to sensitive. GW779439X is an AURKA inhibitor and induces apoptosis by the caspases 3/7 pathway . MRSA:methicillin-resistant S. aureus; MSSA: methicillin-sensitive S. aureus
