4 Claims. 1
This invention relates to a group of compounds having chemotherapeutic activity. More specifl-' cally, the invention provides a group of closely related chemical compounds which have been found to be active against a wide variety of gram negative organisms. In addition, this group of compounds is of particular interest in many of the usual types of intestinal infections. An important object of the invention is to provide compounds for combating various types of gram negative organisms usually associated with intestinal infections, such compounds having low toxicity and freedom from any of the disadvantages usually associated with sulfanilamide therapy. It has also been established as an important feature of the invention that these compounds have shown activity against several organisms which are penicillin resistant.
The group of compounds of the invention have also been found to have a pronounced fung'istatic activity.
The compounds of the present invention are aroyl acrylic acids and their substitution products of the following general formula:
where R. is a member of the group consisting of benzene, naphthalene, and their hydrogenation products, thiophene and pyridine and X is a member of the group consisting of hydrogen, halogen, nitro, amino, alkyl, hydroxyl, alkoxyl, acylamino and cycloalkyl and Y is hydrogen or a salt-forming metal. In addition to having a single substituent'as shown in the above general formula the aroyl acrylic acids may be substituted by a combination of two groups such as halogen and amino, halogen and nitro, alkyl and halogen, and alkyl and amino.
The compounds of this invention may be used in the form of the free acids or in the form of their metal salts. The substances may be incorporated with inert ingredients, such as starch, in the form of tablets. In place of or in addition to the inert ingredients other active ingredients may be incorporated in the tablets. They may also be used in aqueous or oil solution employing for the former the salts, preferably the sodium salt, and for the latter preferably the free acids, or they may be administered without admixture, for example, in gelatin capsules. 7
For use as fungistatic preparations for topical application,- it is advantageous to incorporate from about 2% to about 5% of the zinc salts of the aroyl acrylic acids in a cream of the vanishing type. Powder compositions containing the 2 aroyl acrylic acids or their salts may also be used effectively for this purpose.
The compounds of the general formula may be prepared from the appropriate aryl hydrocarbon and maleic anhydride by the Friedel-Crafts reaction. The aroyl acrylic acids so obtained are usually crystallized from nonpolarsolvents in which case they are obtained as yellow crystalline substances. Recrystallization from water or mixtures of alcohol and water usually gives rise to thehydrates which are, in the majority of cases, colorless substances. In carrying out the Friedel-Crafts reaction between the aryl hydrocarbon and maleic anhydride, excess of the aryl hydrocarbon is to be avoided since addition of the aryl hydrocarbon across the double bond of the preformed aroyl acrylic acid usually occurs. This difliculty is readily overcome by using any of the usual reaction solvents such as nitrobenzene and acetylene tetrachloride, the latter being preferred.
An alternate method for securing certain of the aroyl acrylic acids, particularly those wherein the aryl hydrocarbon is sensitive to the above reaction conditions is to condense fi-carbethoxy acryloyl chloride with the aryl or heterocyclic hydrocarbon in accordance with the Friedel- Crafts synthesis. The Perrier modification of the Friedel-Crafts synthesis has given good yields in both the fl-carbethoxy acryloyl chloride and aryl or heterocyclic hydrocarbon method or maleic anhydride procedure. In certain cases, the acrylic acids are obtained from the corresponding aroyl propionic acids which are monobrominated a to the keto group and then debrominated. These various methods are more specifically described in the following examples without being limited thereto.
EXAMPLE I p-Benzoylacrylic acid To 456 g. of anhydrous thiophene-free benzene and 98 g'. of maleic anhydride there is added gradually at about room temperature 266 g. of anhydrous aluminum chloride. It is preferable to use granular anhydrous aluminum chloride in this and subsequent examples. The reaction mixture is allowed to stand at room temperature preferably with stirring until the evolution of hydrogen chloride ceases, approximately 6-8 hours. The reaction mixture is then cautiously decomposed by the addition of ice and dilute hydrochloric acid, the excess benzene steam distilled and the residue thoroughly chilled. The semi-solid or solid cake is filtered, dissolved in sodium carbonate, filtered, cooled and acidified to Congo red paper with HCl. The hydrated B-benzoylacrylic acid so obtained melts at 60-61 C. On recrystallization from benzene, the anhydrous form is obtained, melting at 98-99 C.
In an alternative procedure, equal molecular quantities of ethyl hydrogen maleate and PC]: are warmed on the steam bath for several hours. The yellow-orange mixture is extracted with anhydrous benzene and the benzene layer treated with maleic anhydride and aluminum chloride as in the previously described method. After decomposition with ice and HCl and steam distillation the benzoylacrylic acid crystallizes out in the form of white platelets, which are dissolved in sodium carbonate filtered and reprecipitated with HCl. Recrystallized from water the acid melts at 60-605" C.
EXAMPLE II p- (p-Chlorobenzo'yl) acrylic acid This compound is prepared from chlorobenzene, maleic anhydride and aluminum chloride in accordance with the procedure of Example 1. After recrystallization from aqueous ethyl alcohol, the compound melts at 153.7-154.7 C.
The reaction may also be carried out in excess chlorobenzene as solvent. Excessive reaction time should be avoided in order to eliminate the formation of the compound resulting from the addition of chlorobenzene across the double bond of the fl-(p-chlorobenzoyl)acrylic acid.
EXAMPLE III p- (p-Bromobenzoyl) acrylic acid This compound is obtained from bromobenzene in accordance with the instructions of Example II and melts at 159-160 C. after recrystallization from aqueous alcohol.
EXAMPLE IV ;9- (p-Iodobenzoyl) acrylic acid This compound is secured from an equivalent amount of iodobenzene with maleic anhydride and aluminum chloride in accordance with the instructions of Example I. Acetylene tetrachloride has been found to be the most suitable solvent The fi-(p-iodobenzoyl) acrylic acid melts at 186-1865" C. after recrystallization from ethyl alcohol.
EXAMPLE v fl- (p-Methylbenzoyl) acrylic acid By reacting one equivalent of toluene with maleic anhydride and aluminum chloride in acetylene tetrachloride, the p-methyl derivative is obtained in excellent yield melting at 137.5- 138.5 C. after recrystallization from benzene. The use of toluene as solvent is very unsatisfactory since toluene adds readily across the double bond of the preformed p-tolylacrylic acid.
EXAMPLE VI p- (p-Isopropylbenzoyl) acrylic acid This compound is obtained from isopropylbenzene in accordance with the instructions of the preceding example. It is a fine yellow crystalline material melting at 103-103.5 C. after recrystallization from ethyl alcohol;
EXAMPLE VII B- 2,5 -dimethylbenzoyl acrylic acid By reacting p-xylene with maleic anhydride 4 and aluminum chloride in acetylene tetrachloride, the compound of this example is obtained melting at 89-90 C. after recrystallization from water.
EXAMPLE VIII p-(2,4-dimethylbeneoyl) acrylic acid This compound is obtained from m-xylene in accordance with the instructions of Example V. After recrystallization from dilute ethanol, the compound melts at 113-114 C.
EXAMPLE IX [3- (a-Thenoyl) acrylic acid This compound is prepared in accordance with the instructions of Example I employing the Perrier modification. To a solution of 61 g. aluminum chloride and 24.5 g. maleic anhydride in 1'75 cc. nitrobenzene cooled to 0 C. there is added gradually with stirring 21 g. thiophene. The reaction mixture is allowed to come to room temperature and then cautiously decomposed with ice and diluted hydrochloric acid. After steam distillation, the residue is cooled thoroughly, filtered and the precipitate dissolved in sodium carbonate. Acidification gives the compound of this example which melts at 148-150 C. After recrystallization from water a pale yellow product is obtained melting at 152-153" C.
EXAMPLE X B- (p-Hydroxybenzoyl) acrylic acid A compound under this name is described by Bogert and Ritter, J. Am. Chem. Soc. 47 532 (1925). When made according to their directions, the compound obtained is a-(p-hydroxyphenyl) S-(p-hydroxybenzoyl) propionic acid as established by analysis.
To obtain the compound of this example, the following procedure is used. To a solution of 450 cc. of acetylene tetrachloride 49 g. maleic anhydride and 128 g. aluminum chloride there was slowly added at or below room temperature 47 g. phenol. The reaction was carried out with stirring and after standing at room temperature for a short while is decomposed as indicated in the previous examples. The product obtained after purification by sodium carbonate treatment and recrystallization from water melts at 196.5- 1975 C. The melting point reported for the compound prepared by Bogert and Ritter is 136 C. identical to that of the substance shown by analysis to be a-(p-hydroxyphenyl) -/3-(p-hydroxybenzoyl) propionic acid.
EXAMPLE XI fi- (Z-methyl-4-hydroarybenzoyl) acrylic acid This compound is prepared in accordance with the directions of the preceding example of using m-cresol. It is a pale yellow crystalline solid melting at 172-173 C. after recrystallization from benzene. Using acetylene tetrachloride in this reaction instead of nitrobenzene gives superior results.

After the addition is completed," the temperature rises to approximately 35 Caand then slowly drops back to approximately 10C; An additiona] 100 cc. of carbon disulfiide is added, the mixture stirred for hour and alter standing for 48 hours was decomposed with ice and dilute hydrochloric acid. The carbon disulilide is removed and the product which separates melts at 225-226 C. Recrystallized from dflute ethanol, the acetylamino compound is obtained as a brilliant yellow product melting at 242-24 4 C.
EXAMPLE XIII (p-Aminobenzoyl) acrylic acid By the hydrolysis of the acetylamino compound described in the previous example there is obtained the compound 01' this example as a reddish solid. Its melting point is indefinite and depends to a large extent upon the rate of heating and initial bath temperature.
