Use of broad-spectrum anti parasitic drugs. For the treatment and
prevention of schistosomiasis, cysticercosis, paragonimiasis,
echinococcosis, Fasciolopsiasis, echinococcosis, worm
infection.
Use as a vermifuge, effective on animal gastrointestinal nematodes.
Can mix in feed use.
Use of the product is of Schistosoma japonicum, Schistosoma mansoni
and S. haematobium, Clonorchis sinensis, paragonimiasis,
Fasciolopsis and taeniasis and cysticercosis been effective anti
worm medicine. Especially strong killing effect on schistosomiasis
tapeworms, is currently the best a middle fruit.
Use of anti worm medicine, mainly for schistosomiasis, also can be
used for the Chinese branch of schistosomiasis, taeniasis and
cysticercosis paragonimiasis, etc.
Production method of industrial production and various synthetic
routes: isoquinoline route, piperazine route and phenylethylamine
route, which better with quinoline route. Catalytic hydrogenation
by isoquinoline with benzoyl chloride and potassium cyanide
addition, rearrangement of *- benzoyl amino methyl *1, 2, 3, four
*- hydrogen isoquinoline, then by chloromethylation, cyclization,
pressurized hydrolysis, cyclohexyl acylation and.
Production method by using phenylethylamine as raw material, by
acylation with chloroacetyl chloride, and then to two benzene
carboxamide potassium amination reaction to introduce amino group,
in three phosphorus oxychloride role under the condition 3, *- two
hydrogen isoquinoline derivatives, *- aminomethyl four
tetrahydroquinoline obtained by hydrogenation, hydrolysis,
successively with cyclohexyl methyl chloride and chloroacetic
chloride acylation, finally dehydrochlorination cyclizes to
praziquantel.
Can also be isoquinoline as raw materials, through Reissert
reaction, at the L position and introduction of cyano nitrogen
benzoylation, then hydrogenation, while benzoyl transfer to the
side chain amino group, then in the ring on the amino introducing
chloro acetyl, then cyclization, hydrolysis, cyclohexyl formylation
to praziquantel.
