Příprava 6-cínnamylidénamino-2-etyltiobenzotiazoluPreparation of 6-cinnamylideneamino-2-ethylthiobenzothiazole
6-Amino-2-etyltiobenzotiazol (21,0 g, 0,1 mól) a cinnamaldehyd (13,2 g, 0,1 mól) sa rozpustili v etanole (60 cm^) a reakčná zmes sa zahriala do varu na 5 mlnút. Potom sa k roztoku přidala studená voda do prvého slabého zákalu, zmes sa odfarbila aktívnym uhlím za varu a roztok sa přefiltroval cez vyhrievaný lievik. Z filtrátu po ochladení na 5 °C sa získal 6-ci.nnamyládénamino-2-etyltiobenzotiazol s t.t. 93 až 95 °C v množstve 26,2 g (80,7 %). Látka nevyžadovala dalšie čistenie. M.h. = 324,47.6-Amino-2-ethylthiobenzothiazole (21.0 g, 0.1 mol) and cinnamaldehyde (13.2 g, 0.1 mol) were dissolved in ethanol (60 cm 3) and the reaction mixture was heated to reflux for 5 ml. . Then, cold water was added to the solution until the first slight turbidity, the mixture was decolorized with boiling activated carbon, and the solution was filtered through a heated funnel. From the filtrate, after cooling to 5 ° C, 6-cyanamethyladeneamino-2-ethylthiobenzothiazole with m.p. 93-95 ° C in an amount of 26.2 g (80.7%). The fabric did not require further purification. M.h. = 324.47.

Účinok študovanej látky na rast a rozmnožovanie anaerobně sporulujúcich baktérií rodu Clostridium sa zisťoval agarovou dilučnou metodou na tuhých živných půdách s různou koncentráciou pridanej študovanej látky. Látka bola rozpuštěná v dimetylsulfoxide. Koncentrácia rozpúšťadla v kultivačnej půdě nepřekročila 1 Použité kultivačně půdy : VI agar a Muller-Hintonov agar (komerčně výrobky Imuny, n.p. Šarišské Michalany), VI agar a MUllerHintonov agar obohatený □ 5 % defibrinovanej konskej krvi. Analogicky bolí naočkované kontrolně půdy bez pridania študovanej látky. Inhibícia rastu kmeňov klostrídií bola hodnotená po 30 a 50 hodinovej inkubácii naočkovaných živných médií v anaeróbnom termostate při 37 °C, kedy kontroly (půdy naočkované testovanými kmeňmi klostrídií bez pridania študovanej látky) dosiahli maximálny rast.The effect of the study substance on the growth and multiplication of anaerobically sporulating bacteria of the genus Clostridium was determined by the agar dilution method on solid nutrient media with different concentrations of added study substance. The substance was dissolved in dimethyl sulfoxide. The solvent concentration in the culture medium did not exceed 1 Culture media used: VI agar and Muller-Hinton agar (commercial products Imuny, n.p. Šarišské Michalany), VI agar and MUllerHinton agar enriched with □ 5% defibrinated horse blood. Analogously, inoculated control soils were in pain without the addition of the study substance. Growth inhibition of Clostridial strains was assessed after 30 and 50 hours of incubation of inoculated nutrient media in an anaerobic thermostat at 37 ° C, when controls (soils inoculated with test Clostridial strains without addition of study substance) reached maximal growth.
Významný je fakt, že zlúčenina podlá vynálezu je novej doteraz neznámej štruktúry a plné inhibuje rast a rozmnožovanie testovaných anaerobně sporulujúcich baktérií rodu Clostridium v koncentrácii 500.10-6 mol dm-3.Significantly, the compound of the invention is of a new hitherto unknown structure and fully inhibits the growth and multiplication of the tested anaerobically sporulating bacteria of the genus Clostridium at a concentration of 500.10 -6 mol dm -3 .
Zlúčeninu podlá vynálezu možno používat’ ako účinnú zložku antibakteriálnych prípravkov samostatné, alebo v zmesi s inými látkami, óalej ako medziprodukt pře ďalšie syntézy.The compound according to the invention can be used as an active ingredient of antibacterial preparations alone or in a mixture with other substances, as well as as an intermediate for further syntheses.
