Descripción general

Research area: IMMUNO AND CKS

Cytochrome P450 (CYP450) is a membrane-bound hemoprotein that constitutes a vast superfamily of heme-thiolate proteins engaged in the metabolism of exogenous and endogenous compounds. These CYP450 enzymes feature an active heme iron center that is bound to a protein molecule via a highly conserved cysteine thiolate ligand.

Aplicación

Cytochrome P450 human has been used in in vitro binding assays to understand protein dimerization via haem–haem stacking and its significance in cancer. It has also been used to study in vitro binding between PGRMC1 and CYP3A4.

Acciones bioquímicas o fisiológicas

Cytochrome P450 (CYP) enzymes are associated with many reactions including O-dealkylation, epoxidation, S-oxidation, and hydroxylation.
Cytochrome P450 is a heterogeneous family of isozymes whose primary function is to oxidize small molecules, both as a function of intermediary metabolism (e.g., fatty acids) and to detoxify exogenous compounds (drugs or toxins). Some isoforms have narrow substrate specificity, while others are promiscuous. The CYP1A1 isoform catalyzes 7-deethylation of ethoxyresorufin. Cytochrome P450 (CYP) plays an important role in detoxifying xenobiotics, cellular metabolism and homeostasis. One of the main mechanisms of drug-drug interactions is the induction or inhibition of these enzymes. CYP enzymes are transcriptionally activated by a variety of xenobiotics and by endogenous substrates via receptor-dependent pathways. Inhibition of these enzymes is a major factor in metabolism-based drug-drug interactions, and many chemotherapeutic medications can cause drug interactions by either inhibiting or inducing the cytochrome p450 enzyme system.

Aminated thioxanthones have recently been described as dual-acting agents: growth inhibitors of leukemia cell lines and P-glycoprotein (P-gp) inhibitors. To evaluate the selectivity profile of thioxanthones as inhibitors of multidrug resistance (MDR), their interaction with other ABC transporters, which were
