Description Luteolin is a flavonoid found in Terminalia chebula, which is a non-selective phisphodiesterase PDE inhibitor for PDE1-5 with Ki of 15.0 μM, 6.4 μM, 13.9 μM, 11.1 μM and 9.5 μM, respectively. Phase 2.

LD50
In vitro Luteolin is a flavonoid found in Terminalia chebula, which is a non-selective phisphodiesterase PDE inhibitor for PDE1-5 with Ki of 15.0 μM, 6.4 μM, 13.9 μM, 11.1 μM and 9.5 μM, respectively. [1] Luteolin inhibits LPS-stimulated TNF-alpha production with an IC50 of less than 1 μM. Luteolin inhibites LPS-induced phosphorylation of Akt as well as IkappaBalpha. [2]
In vivo LD50: Mice >2500mg/kg (i.g.) [3]

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.

Rat dose (mg/kg) = mouse dose (22.4 mg/kg) ×  mouse Km(3)  = 11.2 mg/kg
