Lactones 57-64 protein phosphatase 2 phosphatase activator Homo sapiens 175-186 14677930-2 2003 Thus, an identical 200-fold reduction in protein phosphatase 2A (PP2A) inhibition is observed with either the saturated lactone (7) or with an analogue that lacks the entire lactone (15). Lactones 120-127 protein phosphatase 2 phosphatase activator Homo sapiens 49-63 14677930-2 2003 Thus, an identical 200-fold reduction in protein phosphatase 2A (PP2A) inhibition is observed with either the saturated lactone (7) or with an analogue that lacks the entire lactone (15). Lactones 120-127 protein phosphatase 2 phosphatase activator Homo sapiens 65-69 19592665-6 2009 Notably, a derivative of fostriecin lacking the entire lactone subunit demonstrated marked potency and selectivity for PP2A, while having substantially reduced and similar activity against PP1 and PP1/PP2A- PP5/PP2A-chimeras that have greatly increased sensitivity to both fostriecin and cytostatin. Lactones 55-62 protein phosphatase 2 phosphatase activator Homo sapiens 119-123
