P-gp

P-glycoprotein (P-gp) inhibitors block a drug efflux pump that contributes to multidrug resistance in cells. P-gp, also called multidrug resistance protein 1 (MDR1) or ATP-binding cassette subfamily B member 1 (ABCB1), uses energy from adenosine triphosphate (ATP) hydrolysis. It was first described in 1976 as a surface glycoprotein of drug-resistant Chinese hamster ovary cells. A crystal structure later showed a large drug-binding pocket that accounts for its broad substrate range. Verapamil and its metabolite norverapamil hydrochloride are early inhibitors, and verapamil is also listed under Calcium Channels. Later inhibitors include valspodar, tariquidar, LY335979 and elacridar, which also blocks breast cancer resistance protein (BCRP).

    Voacamine

    Voacamine is an indole alkaloid that acts as an antagonist of the cannabinoid receptor 1 (CB1) and also functions as a P-glycoprotein (P-gp) inhibitor. This compound enhances the efficacy of Doxorubicin by modulating P-gp activity, promoting apoptosis-independent autophagic cell death in human osteosarcoma cells. Additionally, Voacamine activates mitochondrial-associated apoptosis signaling pathways while inhibiting the PI3K/Akt/mTOR pathway, thus suppressing breast cancer progression. Moreover, it demonstrates oncogenic activity against colorectal cancer by inhibiting epidermal growth factor receptor (EGFR).

    A67156

    Budipine

    Budipine is an anti-Parkinson agent that acts primarily as an N-methyl-D-aspartate (NMDA) antagonist while also influencing dopaminergic activity. It enhances dopamine release and inhibits monoamine oxidase type B (MAO-B), contributing to its therapeutic effects. As a substrate of P-glycoprotein (P-gp), Budipine's uptake into the brain is mediated by this transport mechanism. This compound is valuable for research into central nervous system disorders, including Parkinson's disease.

    Budipine hydrochloride

    Budipine hydrochloride functions primarily as an anti-Parkinson agent, targeting the central nervous system. It acts as a substrate of P-glycoprotein (P-gp), facilitating its uptake into the brain. Additionally, Budipine hydrochloride serves as an NMDA antagonist and exhibits indirect dopaminergic effects by enhancing dopamine release and inhibiting monoamine oxidase type B (MAO-B). This compound is valuable for research focused on CNS disorders, particularly Parkinson's disease.
