Mechanism of Action

Targets/IC₅₀/Ki	Reverse transcriptase
In vitro	Efavirenz has direct inhibitory effect on the mitochondrial respiratory function of cultured glioblastoma and differentiated neuroblastoma cell lines. ER stress markers, including CHOP and GRP78 expression (both protein and mRNA), phosphorylation of eIF2a, and presence of the spliced form of XBP1 are upregulated. This compound also enhances cytosolic Ca2+ content and induced morphological changes in the ER suggestive of ER stress. This response is greatly attenuated in cells with altered mitochondrial function (Rho). The effects of this chemical on the ER, and particularly in regard to the mitochondrial involvement, differs from those elicited by a standard pharmacological ER stressor.
In vivo	Efavirenz leads to arterial stiffening but, for the dose and duration tested, did not lead to elevated plaque progression in ApoE(-/-) mice.
