The paper outlines a procedure for manufacturing the anthelminthic Azinox (biltricide) using the new interfacial transfer catalyst benzyl-di-propyl (beta-hydroxyethyl)ammonium chloride. Azinox has been shown to be identical to biltricide (praziquantel) in its properties. Azinox tests on models of Opisthorchis felineus in golden hamsters and of Hymenolepis nana in albino outbred mice have indicated that the agent is not inferior to biltricide in its antitrematodal and anticestodal activities. Azinox displayed a high activity at the preimaginal stages of O. felineus and H. nana and at the larval stage of H.nana.

[The search for new antiparasitic agents. 12.

The paper describes the synthesis of 6-[4-alkylpiperazinyl-1)phenylamino]-1,2,5-thiadiazolo[3,4-h ]quinolines where methyl (Drug G-1574) and ethyl (Drug G-1569) are alkyls. The two agents are as effective as mebendazole against the larval stage of Echinococcus multilocularis infection. Drug G-1574 has been demonstrated to ensure 100% recovery of spontaneously Hymenolepis nana-infected albino mice given doses 2.5-5 times lower than the effective dose of phenasal (niclosamide).

The authors describe the technology of preparing a new anthelmintic agent triclazan, N-(3,4-dichlorophenyl)-2-[(benzo-2,1,3-thiadiazole-4-sulfonyl)amino]-5- chlorobenzamide, finely dispersed (the particles size 4-8 mu). Triclazan is highly effective not only in hymenolepiasis and trichocephaliasis, as was shown previously, but in fascioliasis, monieziasis and intestinal nematodiasis of sheep as well.

[The search for new antiparasitic agents. 10.

Synthesis is described and acute toxicity and antimalaria action is studied in new derivatives of quinoline and benzo(g)quinoline containing a 4-(4-alkylpiperazinyl-1)phenylamine substitute. Only the derivatives of benzo(g)quinoline were found to have a high antimalaria effect and to have advantages over the standard agent chloroquine on their tolerance and protective action. One of the compounds, 4-[4-(4-ethylpiperazinyl-1)phenylamino] benzo(g)quinoline, named QUINOPRAZINE, showed some action against Plasmodium berghei chloroquine--resistant infection (isolate LN-K65). This agent was elected for further tests.

Sulfamidobenzamides containing benzo-2,1,3-thiadiazole ring in the sulfamide group were synthesized and examined for acute toxicity. All the compounds were shown to have low toxicity (when administered orally in a dose of 4 g/kg to mice), the above fact makes possible the search for agents with anthelminthic activity.

The authors describe a method of cultivation and growth peculiarities in a culture of beating cells of the human embryo heart. The influence of homologous anticardiac antibodies and of the ambrosia allergen antiambrosia antibody complex on the contracting cells of the heart of chick and duck embryos was studied in a culture. Pulsation of the cardiac cells was delayed and weakened under the effect of these factors; their vacuolization developed.
