Metabolite Identification
Common NameDiadenosine heptaphosphate
DescriptionDiadenosine heptaphosphate (AP7A) have been isolated in human platelets and have been postulated to play an important role in the control of vascular tone and hemostasis since it inhibits ADP-induced platelet aggregation. AP7A is a potent vasoconstrictors present in human placenta. Diadenosine polyphosphates (APnAs, n = 3-6) are a family of endogenous vasoactive purine dinucleotides which have been isolated from thrombocytes. APnAs have been demonstrated to be involved in the control of vascular tone as well as the growth of vascular smooth muscle cells and hence, possibly, in atherogenesis. APnAs isolated substances are Ap3A, Ap4A, Ap5A, and Ap6A. APnAs are naturally occurring substances that facilitate tear secretion; they are released from the corneal epithelium, they stimulate tear production and therefore they may be considered as physiological modulators of tear secretion. The APnAs were discovered in the mid-sixties in the course of studies on aminoacyl-tRNA synthetases (aaRS). APnAs have emerged as intracellular and extracellular signalling molecules implicated in the maintenance and regulation of vital cellular functions and become considered as second messengers. Great variety of physiological and pathological effects in mammalian cells was found to be associated with alterations of APnAs. APnAs are polyphosphated nucleotidic substances which are found in the CNS and are known to be released in a calcium-dependent manner from storage vesicles in brain synaptosomes.
