RITODRINE Chemische Eigenschaften,Einsatz,Produktion Methoden

Beschreibung
Ritodrine, 4-hydroxy-α-[1-[(4′-hydroxyphenethyl)amino]ethyl]benzylic alcohol (11.1.19), differs slightly from epinephrine, and in the given example only one hydroxyl group has been added to the aromatic ring of the phenylethylamino region of classic sympathomimetics. The second major difference between the examined series is the replacement of the traditionally terminal iso-propyl or tert-butylamine region with a p-hydroxyphenylethylamine. Finally, the third difference is the presence of a methyl group at the α-atom of the phenylethylamine region of sympathomimetics, which makes it similar to isoetharine.
Verwenden
Relaxant (smooth muscle).
Verwenden
Ritodrine is a selective β2-adrenoreceptor stimulant, predominantly of the urino-genital system. It is used as a tocolytic agent for problems associated with premature miscarriages, and only in specialized medical facilities.
Definition
ChEBI: (1S,2R)-ritodrine is a 4-[2-[[1-hydroxy-1-(4-hydroxyphenyl)propan-2-yl]amino]ethyl]phenol that has (1S,2R)-configuration. It is an enantiomer of a (1R,2S)-ritodrine.
Allgemeine Beschreibung
Ritodrine is a selective β2-agonist that wasdeveloped specifically for use as a uterine relaxant. Its uterineinhibitory effects are more sustained than its effects onthe cardiovascular system, which are minimal comparedwith those caused by nonselective β-agonists. The cardiovasculareffects usually associated with its administrationare mild tachycardia and slight diastolic pressure decrease.Usually, it is administered initially by intravenous infusionto stop premature labor and subsequently it may be givenorally.
Clinical Use
Ritodrine is a selective β2-agonist that is used exclusively for relaxing uterine muscle and inhibiting the contractions of premature labor. Terbutaline, in addition to its use as a bronchodilator, also has been used for halting the contractions of premature labor.
Synthese
Ritodrine is synthesized from 4-benzyloxypropiophenone, which undergoes bromination into 4-benzyloxy-|á-bromopropiophenone (11.1.17). This is reacted with 2-(4-benzyloxyphenyl)ethylamine, forming an intermediate product (11.1.18), which undergoes further debenzylation by hydrogen using a palladium catalyst, giving ritodrine (11.1.19) [24,25].
