Diterpenes 19-31 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 98-104 21219911-8 2011 Interestingly, the lowest concentration of both diterpenoids produced a more than 50% reduction in the mRNA and protein expression of CYP3A4 and this reduction was consistent with the enzyme activity. Diterpenes 48-60 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 134-140 21219911-9 2011 Further experiments revealed that both diterpenoids were also capable of attenuating the ability of dexamethasone to induce CYP3A4 expression, and 14-Deoxy-11, 12-Didehydroandrographolide tended to bind to the PXR-LBD site in a concentration-dependent manner. Diterpenes 39-51 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 124-130 21219911-10 2011 SIGNIFICANCE: These diterpenoids are potential CYP3A4 inhibitors and the effects on CYP3A4 may be clinically significant. Diterpenes 20-32 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 47-53 21219911-10 2011 SIGNIFICANCE: These diterpenoids are potential CYP3A4 inhibitors and the effects on CYP3A4 may be clinically significant. Diterpenes 20-32 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 84-90 19795923-4 2009 In human liver microsomes, 7-epi-cephalomannine was subject to C-13 lateral chain (M-1) and diterpenoid core monohydroxylation (M-2), mediated by cytochrome P450 (CYP) 3A4 and CYP2C8, respectively. Diterpenes 92-103 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 146-171 14672753-7 2004 Extensive pulegone metabolism generated p-cresol that was a glutathione depletory, and the furan ring of the diterpenoids in germander was oxidized by CYP3A4 to reactive epoxide which reacts with proteins such as CYP3A and epoxide hydrolase. Diterpenes 109-121 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 151-157
