Metabolite Identification
Common NameMibefradil
DescriptionMibefradil belongs to the class of organic compounds known as tetralins. These are polycyclic aromatic compounds containing a tetralin moiety, which consists of a benzene fused to a cyclohexane. Based on a literature review a significant number of articles have been published on Mibefradil. This compound has been identified in human blood as reported by (PMID: 31557052 ). Mibefradil is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Mibefradil is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.

Enzymes

General function:
Involved in ion channel activity
Specific function:
Voltage-sensitive calcium channels (VSCC) mediate the entry of calcium ions into excitable cells and are also involved in a variety of calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, gene expression, cell motility, cell division and cell death. The isoform alpha-1G gives rise to T-type calcium currents. T-type calcium channels belong to the "low-voltage activated (LVA)" group and are strongly blocked by mibefradil. A particularity of this type of channels is an opening at quite negative potentials and a voltage-dependent inactivation. T-type channels serve pacemaking functions in both central neurons and cardiac nodal cells and support calcium signaling in secretory cells and vascular smooth muscle. They may also be involved in the modulation of firing patterns of neurons which is important for information processing as well as in cell growth processes
