Description
Memória Descritiva
A presente invenção refere-se a um processo para a preparação de novos 5-metoxi-alqui1-amónio, tetetrahidrofurunos e tetrahiurotiofenos com a fórmula geral:
CH3(CH2)12
CH2—0— (CH2) na qual
X representa 0 ou S;
é ura número inteiro desde 1 até 12,
A ú

R R era que
R representa h ou CHy
- um sal de amónio com as fórmulas:
©x CH3 - N_-CH3 S ch3
Θ /=x © Θ z ou X_N(CH3)3 , z é ura aniSo farmaceuticamente aceitável.
A invençSo refere-se a estes compostos quer sob a forma dos seus estereoisómeros separados quer na de qualquer mistura dos mesmos.
Eates compostos sSo mais particularmente interessantes como agente anti RAF (P A F significa factor de agregaçSo de plaquetas /platelets aggregation factor/) com a actividade correspondente como antianafiláticos, antitrombótlcos, anti-isquámicos, imunodepressores e actuam também contra alteraçS© imune do rim, contra vários choques, contra alergias da pele e úlceras intestinais induzidas por endotoxina, por exemplo
O proceeeo de preparação de acordo com a invenção consiste em fazer-se reagir um composto com a fórmula I CH3<CH2>12
I
CH _O_S_ CH
I com um composto com a fórmula II
NaOB II na qual
Β β o precursor de A gue contém um grupo amino ou B - A.
A reacção efectua-se de maneira adequada num solvente como dimetilformamida a uma temperatura de 6O-8O°C. A transformação de B para A é obtida por vias normais»
Os materiais de partida com a fórmula I podem ser preparados por meio da reacção de um composto com a fórmula III
CH3(CH2)i2
III ch2 oh com cloreto de me tanoaulfonilo em benzeno-piridina, seguida por tratamento clássico.
composto com a fórmula II é preparado por meio da reacção de hidreto de sódio com o amino álcool o correspondente BOH em DMF a 50-60 G.

Pm sso a» Preparação de 2-tredeeil-5-dimetilamino-etoxi-metil- tetrahidrofurano. A » (GH2) 2N(GH3) 2
A 1,13 g (12,7 mmoles) de dimetilamino etanol em 100 ml de dimetilformamida seca adicionaram-se 0,51 g (12,7 mmoles) de NaH (60% de dispersão em óleo). A mistura foi aquecida durante 30 minutos a 60°C mantendo em agitação, e, em seguida, juntaram-se 2,3 g (6,35 mmoles) de 2-tredecil-tetrahidrofurano 5-metanol metano sulfonato. Depois de se aquecer durante mais duas horas a 80°C mantendo em agitaç*a, a mistura foi arrefecida e o excesso de NaH foi decomposta por meio da adição de 5 ml de MeOH. A evaporação da maior parte de DMF conduziu a um resíduo que foi diluído com água e extraído três vezes com áter dietílico. A camada orgânica foi lavada oom água atá neutralidade, seca (MgSO^) e evaporada em vácuo, 0 composto em titulo impuro foi seguidamente purificado por meio de cromatografia sobre gel de sílica empregando 1 a 5% MeOH em CHCl^ como eluente para se obterem 0, 9 g (40) sob a forma de óleo.

0,5 g (1,4 mmoles) do composto preparado no passo a) acima e um excesso de iodeto de metilo (2 g, mmoles) em 50 ml de acetona seca foram mantidos em agitação durante 2 horas à temperatura ambiente. Depois da eliminação do dissolvente e do excesso de Mel, o residuo foi eromatografado sobre uma coluna de gel de sílica empregando 5% a 20% MeOH em CHC13 como eluente que conduz ao composto em título sob a forma de um sólido amarelo, pf » 1O4°C.

Oa CMpeetea da acordo coo a praaeata inwsiçlo fiorao odotalatradoa a ratoa para a detarmlaaçfo da
LDjq aguda. Para todos os compostos da invenção, a LDjq excedei 300 mgAg (IP ou SC) e 600 mg/kg (PO).
FARMACOLOGIA uma prova do interesse farmacêutico dos compostos de acordo com a invenção foi estabelecida por meio da experiência farmacêutica seguinte.
Inibição da agregação de plaguetas em coelhos da Nova Zelândia
A experiência efectuou-se em plaguetas com plasma de coelhos da Nova Zelândia.
Tiraram-se amostra3 de sangue da artéria auricular e colocararo-se em tampão citrato (3,8%; pK 7,4); o sangue foi depois centrifugado durante 15 minutos a 1200 RPM.
A amostra experimentada foi preparada em DMSO, em seguida despejada sobre plasma rico em jiaquetas durante 1 minuto, e, em seguida, foi adicionada uma dose de
2,5 nM de PAF.
A determinação é feita num aparelho Cronolog Coultronics que determina a percentagem de transmissão correspondente â altura máxima do pico antes da desagregação.
A percentagem de variação da inibição em relação â percentagem de transmissão é calculada (controlo; DMSO puro).
Este método foi descrito pormenorizadamente em LABORATORY INVESTIGATIONS, Vol. 41, N® 3, p. 275,
1979, JEAN-PIERRE GAZENAVE, Dr. MED., JACQUES BENVENISTE, Dr.
MED., E J. PRASER MUSTARD, E.D., A Agregação de Plaguetas de
Cbelhos por meio de Factor de Activação de Piaguetes é independente da Reaoção de Libertação e do Percurso de Araquidonato e e inibido por Medicamentos Activos em Membrana.
Os resultados demonstram que os compostos inibem a agregação induzida por 2, 5 nM de PAF, Cinco experiências feitas em cinco coelhos diferentes permitiram-nos calcular o IC^ dos vários compostos empregando o test de regressão linear.
Os valores de IC^ em plaquetas foram os seguintes»
