Today, ergot alkaloids have found widespread clinical use and more
than 50 formulations contain natural or semisynthetic ergot
alkaloids. They are used in the treatment of uterine atonia,
postpartum bleeding, migraine, orthostatic circulatory
disturbances, senile cerebral insufficiency, hypertension, hyp-
prolactinemia, acromegaly, and Parkinsonism. Recently, new
therapeutic - plications have emerged, e.g., against schizophrenia
and for therapeutic usage based on newly discovered antibacterial
and cytostatic effects, immunomodu- tory and hypolipemic
activity.The broad physiological effects of ergot alkaloids are
based mostly on their interactions with neurotransmitter receptors
on the cells. The presence of "hidden structures'' resembling some
important neu- humoral mediators (e.g., noradrenaline, serotonin,
dopamine) in the molecules of ergot alkaloids could explain their
interactions with these receptors 1]. Ergot alkaloids are produced
by the filamentous fungi of the genus, Claviceps (e.g., Claviceps
purpurea - Ergot, Mutterkorn). On the industrial scale these
alkaloids were produced mostly by parasitic cultivation (field
production of the ergot) till the end of the 1970s. Today this
uneconomic method has been - placed by submerged fermentation. Even
after a century of research on ergot alkaloids the search still
continues for new, more potent and more selective ergot alkaloid
derivatives.
