Description

Oblast techniky
Vynález se týká (S)-3-(fenylacetamido)-3-(3-pyridyl)-propionové kyseliny a způsobu její přípravy. Tato kyselina slouží jako meziprodukt pro přípravu karboxamidových derivátů pyrrolidinu, piperidinu a hexahydroazepinu. Posledně uvedené sloučeniny mohou být použity jako léčiva pro léčení trombotických poruch zprostředkovaných destičkami.
Dosavadní stav techniky
Racemickou 3-(fenylacetamido)-3-(3-pyridyl)propionovou kyselinu je možno připravit podle E. Profft, J, Prakt. Chem. 1965, 30, 18. Její S-enantiomer, který je předmětem tohoto vynálezu však dosud nebyl popsán.
Podstata vynálezu
Předmětem vynálezu je (S)-3-(fenyIacetamido)-3-(3-pyridyl)propionová kyselina vzorce AG4
(AG4)
Dalším předmětem vynálezu je také způsob výroby sloučeniny AG4, jehož podstata spočívá v tom, že se 3-(fenylacetamido)-3-(3-pyridyl)propionová kyselina vzorce AG3
(AG3) nechá reagovat s penicilinamidázou.
Ve výhodném provedení tohoto způsobu se postupuje tak, že se se penicilinamidázou působí na vodný roztok sloučeniny vzorce AG3, jehož hodnota pH byla předběžně nastavena na asi 7,5.
Výchozí 3-(fenylacetamido)-3-(3-pyridyl)propionová kyselina vzorce AG3 se připravuje za použití modifikovaného Knoevanagelova postupu (schéma AG; E. Profft, J. Prakt. Chem. 1965, 30, 18). Kyselina vzorce AG3 se způsobem podle vynálezu obohatí o S-enantiomer selektivním štěpením pomocí penicilinamidázy (V. A. Soloshonok, Tetrahedron:Asymmetry 1965, 6, 1601).

Nežádoucí R-enantiomer se pomocí amidázy hydrolyzuje, zatímco S-enantiomer si udrží fenylacetylovou skupinu.

Kyselina vzorce AG4 slouží jako meziprodukt pro přípravu karboxamidových derivátůpyrrolidonu, piperidinu a hexahydroazepinu obecného vzorce I:
ť (CH^-A (l) kde:
A je zvolen ze souboru zahrnujícího 2-piperidyl, 3—piperidyl, 4-piperidyl, 1-piperazinyl, 2-pyrrolidinyl, 3-pyrrolidinyl a NHR2;
R2 je zvolen ze souboru zahrnujícího H, alkyl s 1 až 8 atomy uhlíku a acyl se 2 až 6 atomy uhlíku a přednostně znamená vodík;

p je 2 nebo 3;
q je 1, 2 nebo 3 a přednostně 1;
R3 je alkyl s 1 až 8 atomy uhlíku, alkenyl se 2 až 8 atomy uhlíku, alkinyl se 2 až 8 atomy uhlíku, fenyl, naftyl, fenylalkyl s 1 až 8 atomy uhlíku v alkylové části, naftylalkyl s 1 až 8 atomy uhlíku v alkylové části nebo heteroaryl, kterým může být pyridyl, thienyl, furyl, nebo chinolyl;
R4 je vodík nebo alkyl s 1 až 8 atomy uhlíku nebo cykloalkyl s 5 až 8 atomy uhlíku a přednostně znamená vodík;
Z je CO2H, CO2alkyl, SO3H, PO3H2 nebo 5-tetrazol.
Sloučeniny obecného vzorce I, které jsou předmětem základního patentu, jsou inhibitory agregace destiček a jako takové jsou užitečné při léčbě trombotických poruch zprostředkovaných destičkami, jako je arteriální a venózní trombóza, akutní infarkt myokardu, nestabilní angína, reokluze následující trombolytickou terapii a angioplastiku, zápal a různé vazookluzivní poruchy. Tyto sloučeniny jsou užitečné také jako antitrombotická činidla použitá v souvislosti s fibrinolytickou terapií (například t-PA nebo streptokináza).
Přiklad provedení vynálezu (S)-3-(Fenylacetamido)-3-(3-pyridyl)propionová kyselina
3-(Fenylacetamido)-3-(3-pyridyl)propionová kyselina vzorce AG3 se připraví za použití standardních způsobů, jak jsou znázorněny ve schématu AG (E. Profft, J. Prakt. Chem. 1965, 30, 18). Roztok sloučeniny AG3 (0,225 mol) ve vodě (600 ml) se při teplotě místnosti nastaví na pH 7,5 za použití KOH (3,0 N) a nechá reagovat s penicilinamidázou (91 502 jednotek, Sigma). Tato směs se míchá 47 hodin, okyselí na pH 1 pomocí HC1 (konc.) a výsledná sraženina se odfiltruje přes celatom FW-14. Filtrát se extrahuje Et2O (3 x 300 ml) a zkoncentruje ve vakuu.
