Ry, Tepresents a hydroRen atom or a methyl group; and
Rs represents a cyclohexyl or hydroxy- cyclohexyl group, and the pharmacologically accept- . 5 able acid addition salts thereof with d¢norganic or organic acids, inhibit or prevent the colonigation of surfaces by microorganisus, particularly in the oral and pharyngeal cavity, in the lungs, in the urogenital tract, in the lnammary glands, on the oo skin, and in the conjunctival membranes,
Preferred compounds of Formula 1 are those wherein R, and Ry together with the nitrogen atom between them represent the N-methyl-cyclohexyl- amino, cis-3phydroxy-cyclohexylamino, or trang-4¢ hydroxy-cyclohexylamino group. ihe compounds

The compounds of Formula I may further- more be converted into their addition salts, especially into thetr pharmacologically acceptable salts with inorganic or organic acids. Suitable acids may be, for example, hydrochloric acid, hydrobromic acid, gulfuric acid, phosphoric acid, lactic acid, citric acid, tartaric acid, succinic acld, maleic acid, or fumaric acid.
Thus, according to the invention, by applying a compound of Formula 1, the risk of in- : fection uy microbes is reduced or eliminated by a reduction in the ability of the microbes to adhere to the cell walls. This is particularly true with regard to the oral and pharyngeal cavities, the lungs, vagina, and mammary glands. ror example, this prophylactic activity of the compounds
A = N-methyl-N-(2-amino-3, 5-dibromo- bengyl)-cyclohexylamine hydrochloride and
B = N-(2-amino-3,5-dibromo-benzyl)-trans- 4-hydroxy-cyclohexylamine hydrochloride was tested as follows: 1. Direct activity in the in vitro system (a) The titre of the living cells, e.g.» human epithelial cells from the lungs such as ATCC, .

Three milliliter portions of tiis suspension are poured into glass scintillation vials which have been prepared by the usual treatment for the adhesion of epithelial cells to the surface of the glass. : they are incubated for three days at 37°C with 3%
Co, until a sealed monolayer is formed. A monolayer corresponds to 5 x 10° cells per scintillation vial. (b) The bacteria, e.g., Klebsiella pneumo- niae Weingarten 14, are cultured in Brain Heart
Infusion Broth (BHI) in two passages lasting 24 hours each at 37°C until the logarithmic growth phase is reached. During the second passage, radio- active labelling is carried out by the addition of 1,2-*4c-acetate to the culture medium. Then the culture is washed twice with PBS (phosphate bufferred saiine) to eliminate any non-incorporated radioactivity. Using PBS of pH 5,5, the culture is adjusted to a transmission of 35 % in a photometer, corresponding to a titre of 5 x 108 bacteria/ml,
ful. 26¢72— by determination of the number of living pathogens. (¢c) The bacterial culture is centrifuged, and the PBS ie taken off and replaced by the same volume of benzylamine solution in PBS of pH 5.5.
For the control, FBS of pH 5.5 is used instead of the benzylamine solution.
The culture medium of the cells is removed, the monolayer (= 5 x 10° cells) is rinsed twice with PB5 of pi 5.5%, and is covered with 1 ml of bacterial benzyiamine solution (z= 5 x 108 baceteria).
Incubation is carried out .or three hours at 37°C,
Then the bacterial benzylamine solution is removed, and the monolayer 1s rinsed twice with
PBS of pli 5.5 to remove any non-adhering bacteria.
After addition of INSTAGrL (registered trade mark of Messrs. Fackard, USA, the composition was not disclosed) the radioactivity of the bonded bacteria is measured in a scintillation counter. (d) Hesults: alth Compound A (50 pg/ml) 1Y % fewer bacteria were detected on the epithelial cells, by comparison with the control, while with Compound
B (50 ug/ml) 20 % fewer were found. 2, Indirect activit in the ex vivo system (a) The epithelial cells are grown as described above.
fof. 76473 (b) The bacteria are grown as described above, (¢) Male SPF rats (Chbb:THOM) are treated orally for five days with 25 mg of benzylamine per kg of body weight or with TYLOSE (R) a water- soluble cellulose ether available trom the
Hoechst Corp., as control. Lung lavage material is obtained vy brouchoalveolar lavage with isotonic urea solution and then pooled. Une hundred milli- liters of thie iluid are divided into 30 protein- containing gel fractions by preparative isoelectric focussing. After the isdelectric point of indi- vidual fractions has been determined with a surface electrode, the proteins are eluted from the gel with 3 ml of PBS, pil 5.5, for each fraction. The 30 fractions are adjusted to a pH of 5.5, (d) The bacterial culture is centrifuged and PBS is removed and replaced by the same volume : of bronchoalveclar lavage fraction. For the control, instead of the bronchoalveolar lavage fractions,
PBS of pH 5.5 and isotonic urea solution, treated in the same way, are used. After two hours, incubation at 57°C the bacterial culture is centri- fuged again, bronchoalveolar lavage fractions or
PBS or urea are removed and replaced by the same volume of PBS of pH 5.5.

The culture medium of the cells is renoved, the monolayer (= 9 Xx 10° cells) is washed twice with PBS of pH 5.5, and 1 ml of bacterial sus- pension (= 5 x 10° bacteria) is poured dver it.
Incubation is carried out tor two hours at 37°C.
The bacterial suspension 1s then removed, and the monolayer is rinsed twice with I'Bs of pH 5.5 to remove any non-adhering bacteria. After the addition of INSTAGEL, the radioactivity of the bound bacteria is measuredin a scintillation counter. (e) Results?
In repeated testswith Compound B, adhesion- increasing mediator proteins were detected in 8 fractions with reproducible igoelectric points.
In treated animals, this mediator-caused increased in adhesiveness was gignificantly reduced compared with the control animals. The results are agsembled in the tollowing table: -& -

The compounds of formula I and the pharma-~ cologically acceptable acid addition salts thereof are non-toxic and therefore well tolerated. Thus, for example, in the mouse : - N-methyl-N-(2-amino-3,5-d1bromo-bensyl )- cyclohexylamine hydrochloride has an
Lbg, of »10 gm/xg p.o., - 8-(2-amino-3, 5-dibromo-benzyl )-trans-4- hydroxy-cyclohexylamine hydrochloride
KE 10 has an Lg, of 2.72 gm/kg p.o., and ~ the other compounds have an LD, of
YL gm/kg p.o.
In view of their inhibiting effect on the adhesiveness of microorganisms, discovered accord- ing to the invention, the compounds of Formula I are sultable for the prophylaxis of infections such +, as infections of the respiratory tract, urogenital tract, mammary glands, akin, and conjunctival membranes, and particularly also for hygiene of the oral and pharyngeal cavities.
To achieve the activity according to the invention, the compounds of Formula I and the pharmacologically acceptable acid addition salts Te thereof with inorganic or organic acids may be administered, optionally in combination with other fad. 26472 active ingredients, preferably substances which =~ additionally guard against infection by microbes, such es sulfonamides or antibiotics, e.g., tetra- cycline, doxycycline, ampicillin, amoxycillin,
cephalexin, or erythromycin, to warm-blooded animals perorally, parenterally, topically, or rectally as active ingredients in customary pre- paration forms suitable for the intended purposes, that is, compuszitions consisting essentially of an inert pharmaceutical carrier and an effective amount ot an inert pharmaceutical carrier and an effective amount of the active ingredient, such as tablets, coated tablets, capsules, granulates, suppositories, solutions, suspensions, emulsions,
ampules, drops, intments, gels, pastes, creams, powders, wound dressings, and sprays.
Advantage- ously the active ingredient or a mixture of dif- ferent active ingredients of Formula I may be administered orally to both humans or animals, in a single dose of trom about 1 to 200 mg (0.013 to
2.67 mg/kg ol body weight), preterably from about © to 150 mg (0.11 to 2.0 mg/kg of body weight), several tives, e.g., from one to four times, daily and externally in a concentration of from about 0.01 to 20 mg per ml or gm of prepara- tion.
A daily dose is therefore trom about 1 to $00 wg (from about 0.013 to 10.7 mg/kg of body weight), preferably from about © to 600 mg (from fuf. 2477 about 0.11 to ..0 mg/kg of body weight). Depending upon the type and body weight of the patient to be treated, on the type and severity of the afflict- ion, on the type of preparation, and on the route of administration as well as on the period or interval over which the administration takes place, it may, however, be necessary to deviate from the
Co above dosages. Thus, it may sufficient in some cases to administer less than the above-mentioned amounts of active ingredient and in some cases the amountg must be exceeded. I'he optimum dosage and route of administratipn of the active ingredients which are necessary in each case can easily be determined by one skilled in the art.
