Preparation of a therapeutic composition
View Patent ↗Product R, a novel therapeutic composition for treating viral infections and stimulating the immune system, comprises a unique peptide having 31 amino acids and another unique peptide having 21 amino acids and connected with an oligo-nucleotide through a diphosphodiester or diphosphodithioate ester linkage. The composition has a light absorption spectrum with typical absorption ratios of 1.998 at 260 nm/280 nm and 1.359 at 260 nm/230 nm.
1. A purified peptide of SEQ ID NO: 1.
2. The purified peptide of claim 1 , wherein said peptide is formed by a process comprising the steps of:
a) forming a mixture including a protein combination consisting of casein, beef peptone and bovine serum albumin, a plant RNA and a base in water, wherein the ratio of said protein combination to said water is in a range from about 1.5/100 to about 2.5/100 by weight.
b) processing said mixture at an elevated temperature and an elevated pressure so as to form a solution and insoluble elements;
c) removing said insoluble elements;
d) diluting said solution with water; and
e) after performing steps b, c and d, adjusting the pH of said solution to a physiologically acceptable pH.
3. The purified peptide of claim 1 , wherein said peptide is chemically synthesized.
4. A pharmaceutical composition, comprising a purified peptide of SEQ ID NO: 1 and a pharmaceutically acceptable carrier.
5. A pharmaceutical composition, comprising (a) a purified peptide of 31 amino acids, lacking any cysteine-cysteine cross links, comprising six proline residues and four glutamine residues, and being capable of stimulating the production of interleukin-8 in cultured cells; and (b) a pharmaceutically acceptable carrier.
6. A pharmaceutical composition, comprising (a) a purified peptide of 31 amino acids, lacking any cysteine-cysteine cross links, comprising six proline residues and four glutamine residues, and being capable of stimulating the production of monocyte chemotactic protein 1 in cultured cells; and (b) a pharmaceutically acceptable carrier.
7. The purified peptide of claim 2 , wherein said elevated temperature is about 150 to 300° F. and said elevated pressure is 5 to 15 lbs.
