  PENICILLIN SALTS, AND PROCESS FOR THEIR PREPARATION.



   The present invention relates to novel amine salts of penicillin.



   The novel amine salts of the present invention have the following general formula:
 EMI1.1
 or R1, R2, R and R4 are members of the class consisting of hydrogen and lower alkyls; R is an element of the class consisting of hydrogen and hydroxyl; and Pen denotes the acid radical of penicillin or an active part of this radical, capable of forming an addition salt with the amine mentioned.



   It should be noted that in cases where the radicals R4 and R5 are not identical, there are two asymmetric carbon atoms. However, the invention is not limited to any particular isomer, but includes all

 <Desc / Clms Page number 2>

 the possible isomers,
The penicillin amine salts of this invention are able to exert a prolonged reserve antibiotic action,
The invention will be well understood by reference to the following examples.



   EXAMPLE 1.



   =================
 EMI2.1
 Penicillin alpha, beta-diphenyl beta-hydroethylamine salt
 EMI2.2
 
0.48 gr is added. of alpha, beta-diphenyl-beta-hydroxyethylamine hydrochloride dissolved in 6 ml of distilled water, a solution which contains 1 gr. sodium penicillin G in 4 ml of water. The solution is stirred well, and an oil precipitates. Crystals are formed by friction and agitation. After standing for half an hour in an ice bath, the crystals are filtered and dried in a vacuum desiccator.



   One test indicates a potency of 1207 units / gram and a water solubility of 6630 units / milliliter.



   EXAMPLE 2.



   =================
 EMI2.3
 Alpha salt. btamd3nhé .y3. penicillin beta-hydro Nnethylethylamine
 EMI2.4
 
 EMI2.5
 0.46 gr is added. of alpha, beta-diphenyl-bata-hydroxy-N-methylethylamine hydrochloride dissolved in 5.5 ml of water a solution of 1 gr. of sodium penicillin G in 4 ml of water. The rushing oil turns into

 <Desc / Clms Page number 3>

 crystals by friction and riddling. The crystals are filtered, and dried in vacuo.



   EXAMPLE 3.



  Alpha, beta-diphenylethylamine salt of penicillin
 EMI3.1
 
A solution of 1.5 gr is added. of sodium penicillin G in 5 ml of water to a solution of 1 gr. of alpha, beta-diphenylethylamine hydrochloride in 7 ml of water. By rubbing and stirring the solution, crystals are produced which are filtered and dried in vacuum.



   EXAMPLE 4.
 EMI3.2
 



  Alpha salt, btamc.liphenyl beta h, y, dro rop ,, penicillin amine
 EMI3.3
 
Added to 0.30 gr. of alpha hydrochloride, beta-di-phenyl-beta-hydroxypropylamine in 6 ml of water, a solution of 1 gr. of sodium penicillin G dissolved in 4 ml of water. The oil which is precipitated by riddling turns into crystals by friction. The crystals are filtered and placed in a vacuum desiccator.

 <Desc / Clms Page number 4>

 



  EXAMPLE 5.



  =================
 EMI4.1
 Alpha salt. penicillin beta-dibhenylmbea hdroxl N. N-diethlam3.ne
 EMI4.2
 
0.70 gr is added. of alpha, beta-diphenyl-beta-hydroxy-N, N-diethylamine hydrochloride in 9 ml of water, 2 gr. of sodium penicillin G dissolved in 8 ml of water. The oil which precipitates turns into crystals on standing and rubbing. These crystals are filtered and dried in vacuo.



   Although the present invention has been described with particular reference to the amine salts of penicillin G, it will of course be understood that the salts of other penicillins are also within the scope of the present invention; examples of these products are penicillins G, X, dihydro F and K.

   2. Penicillin G and alpha salt, beta-diphenyl-beta-hydroxyethylamine.
 EMI4.5
 



  3. Penicillin G salt of alpha, beta-diphenyl-beta-hydroxr-N-methylethylamine.
