No Drawing. Application June 9, 1954, Serial No. 435,617
16 Claims (Cl. 260--256.4) This invention relates to quaternary-compounds and relates more particularly to certain quaternary salts of thonzylamine, i. e., N,N-dimethyl-N"-'(p-methoxybenzyl)- N -(2-pyrimidyl)-ethylene diamine.
An object ofthis invention is the production of novel quaternary ammonium salts having desirable solubilizing and other surfactant properties.
Another object of this invention is the provision of novel solubilizing agents which are particularly valuable as solubilizing agents for antibiotics such as, for "example, gramicidin, tyrothricin, subtilin, etc.
A further object of this invention is, the provision of quaternary ammonium salts which are effective mucolytic agentsfor the solubilization of secretions of then'os e, throat and lungs, and which may be administered satisfactorily by aerosoliz'ation techniques.
Other objects of this invention will appear from the followingdetailed'description.
The solubilization of many therapeutic organic compounds frequently presents a serious problem in the practical application of such compounds, especially Where the use of organic solvents, such as alcohol, is"undesirable. Thus; for example, gramicidin isquite insoluble in water, and where the use of an aqueous medium is'of importance, the only manner in which the gramicidin can be employed is in the form of a suspension. Not only does this limit'the practical concentrationof the antibiotic which can be made available for action, butthe'preparw tion of stable suspensions is'also' a matter of-no little difliculty. I
I have'now found that quaternaryaminoniuin'salts of I the" general formula where R is an alkyl group up. to about 20 carbon atoms and X is the anion of an acid; comprisehighly-effective" solubilizing agents which are particularly valuable for solubilizing ditficultly soluble antibiotics In addition; these salts exhibit bacteriostatic action against various organisms, especially Staphylococcus au'reusa'nd as such, comprise highly. elfective disinfectant materials.
The novel quaternary ammonium'salt's of my inventionare also highly effective as 'mucolytic agentsand exhibit. marked ability to reduce the viscosity of many thick, tenacious secretions of the nasal, pharyngeal andbron'chialpassages frequently encountered in cases of pneumonia and plumonary tuberculosis. One highly eflective manner of administering these quaternary ammonium salts for maximum mucolytic activity is in the form of 'an aerosol; This technique involves the nebuliz'ation ofa'p'fedeter mined amount of an aqueous solution 'containingrfrom' as little as 0.01% to 1.0% by weight of the quaternaryam' monium salt into a relatively confined space, such' a's-a tentor, preferably, a mask, and the patient under -treatmentiin I United States Patent hales the resulting mist or aerosol. The mucolytic-agent is thus brought into directand intimate contact with the secretions present in the nose, throat and lungs. This therapy causes a marked loosening and liquefaction of the secretions. In many instances-the sputum flow is greatly.
increased. The application of the novel quaternary; atnmonium salts of my invention to the treatment'of the premature new-born by this aerosolization technique is particularly effective in those instances Where the infants are born with or develop atelectasis. The nebulization of an'aqueous solution of 'said quaternary ammonium salt'into an isolette, incubator or croup tent to produce an aerosol has been associated with a definite decrease in mortality of such premature infants. The aerosol mayv also 'be administered concurrently With oxygen therapy- A typical formulation which has' been'found to be clinically efiective in mucolytic therapy contains 0.1546 0.20 gram of N,N-di methyl-N-(p-methoxybenzyl)-N'-(2 pyrimidyl)-Ncetyl-N-bromo-ethylene diamine, or other of the novel quaternary ammonium salts of my invention, dissolved in 10.0 grams of propylene glycol, which is then brought up to a volume ofmL Withdi'stiIIed water and" buffered to a pH of 7.4 with sodiumcarbonate.
As examp'les-of acid anions which may constitute that portion of the above general formula representedby the substituent X, there may bementioned'the anions of such inorganic acids as hydrochloric acid, hydrobromic acid, hydriodic acid, sulfuric acid and the several phosphoric acids. Those compounds containing halogen asthe inorganic anion in the quaternary ammonium salt structure are preferable since they are-most conveniently andccO- nomically obtained. 7 The novelsalts of iny invention may be produced, for example, by dissolving the 'thonzylamine base in a suit;-
able organic solvent such as benzol, toluene or-xylene,
and 'then adding an alkyljhalide 'to the solution. Uponstanding or upon-moderate heating, the desired alkyl'halide quaternary ammonium salt of thonzylamineisformed," The amine base 'may also 'be 'rea c'tedlwith analkyl halide directly and without the use'of'a solvent'by mixingithe reactants and Warming at 40 to 100 C., for about 8to'72 hours. Mol ratios are preferablyr'employed. The iodide, bromide or chloride may be readily formed in this man her." If an iodide salt is 'fo'rmedhiuitially, itim'ayfbe readily converted to the corresponding bromideor Iclilo' ride salt by-r'eacting' said'iodide" salt with' eitherisilver bromide or" with silver chloride; forexa'mple, so as tore place the iodine in the salt by an atom" of chlorineor" bro minasthe' case mayhbe. Furthermore, the alanine; chlbride'or iodide salt may also be converted to the cor responding sulfate salt by reacting these antigen-sans with silver sulfate or, where a phosphate salt is desired, by reacting any one of the halide salts with silver phos- In' addition, the novel quaternary salts of my invention may also be made by reacting an "N- (p 'methoxybe'n' Example I 1 2.86 parts by Weight of thonzylamine base are dissolved in 22 parts by weight of benzo'l and tothe solution thus obtained are added 1.42 parts-by Weight of methyl' iodide; The reaction mixture is maintained at room temperature and the quaternary ammoniunrsai-t- N,N-dimethyl-N-(pmethoxybenzyl) N' -,(2' pyrimidyDgethylehediarnine N-methyliodide percipitates from the solution.

On cooling the ratfinate, solidification takes place and the recrystallization of the solid material from ether-isopropanol yields 5.5 parts by weight of white crystalline N,N-dimethyl-N-(p-methoxybenzyl)-N-(2-pyrimidyl)-ethylene diamine-N-acetyl bromide. This compound has a melting point of 9192 C., is soluble in alcohol and is slightly soluble in water.

The N,N-dimethyl N (p methoxybenzyl) N (2 pyrimidyl)- ethylene diamine-Nm-dodecyl chloride obtained has a melting point of 75-78 C. and is soluble in water and alcohol.
The novel quaternary ammonium salts of thonzylamine of my invention are as stated, effective disinfecting agents against various bacteria. In vitro tests against Staph. aureus demonstrate that the n-decyl bromide, lauryl bromide, cetyl bromide and n-decyl iodide quaternary salts of thonzylamine, for example, show effective bacteriostasis in concentrations of less than 0.25 mg.%. The test is carried out as follows:
10 ml. of a suitable nutrient medium is added to each of ten test tubes and the compound to be tested is dis solved or suspended in some of the nutrient medium in a concentration of 128 mg.%. 10 ml. of the resulting solution is added to the second tube and the mixture thoroughly mixed. 10 ml. of the mixture is removed from the second tube, added to the third tube. mixed and the dilution method continued down through the tenth tube. The 10 ml. removed from the last tube are discarded. The first tube, to which nothing is added, serves as a control. The concentration of the test compound in the tubes varies in'amount from 64 mg.% down to 0.25 mg.%. Each tube is then inoculated with an inoculum of 0.1 ml. of a 1-500 dilution of an 18 hour culture of Staph. aareus. and the tubes incubated for 72 hours. The bacteriostatic and stable.
is also quite active against Streptococcus hemolytz'cus and,
Klebsiella pneumoniae.
In addition to the antibacterial activity exhibited by the quaternary ammonium salts of thonzylamine, these compounds also exhibit marked antifungal activity and are particularly active against Tricophyton melztagrophytes, Trichophyton rubrum, Sporotrichum schenkii and Penicillium digitatum. For example, against T richophyton mentagrophytes the cetyl bromide quaternary of thonzylamine is fungistatic in a concentration of 0.2 mg.%, against Tricophyton rubrum in a concentration of 0.04 mg.%, against Sporotrichum schenkii in a concentration of 0.2 mg.% and Penicillium digiiatum in a concentration of 1 mg.%. This compound is also fungistatic in a concentration of 5 mg.% against Candida albicans.
