Patent No. 8,372,448

“Method for enhancing the DNA repair process, treating disorders associated with the DNA repair process, enhancing antitumor response and treating disorders associated with anti-tumor response in mammals by administering purified quinic acid and/or carboxy alkyl ester.”

Patent Number 8,372,448: This patent is directed toward a method for enhancing the response to tumor formation or growth in a mammal by inhibiting TNF-Alpha production or inducing apoptosis of white blood cells by administering a pharmaceutically effective amount of purified, isolated quinic alkyl esters having an UV absorption of approximately 200 nanometers and a bioassay efficacy using IC50 in HL60 cell line of less than 100 micrograms per milliliter, where said amount is effective to inhibit TNF-Alpha production or to induce apoptosis of white blood cells where administration is other than topical.

Patent No. 8,372,449

“Method for enhancing the DNA repair process, treating disorders associated with the DNA repair process, enhancing anti-tumor response and treating disorders associated with anti-tumor response in mammals by administering purified quinic acid and/or carboxy alkyl ester.”  

Patent Number: 8,372,449: This patent is directed toward a method of enhancing the response to tumor formation and growth in a mammal by administering a pharmaceutical composition comprising a purified isolated compound selected from a group consisting of quinic acid and quinic acid salt, where said quinic acid and quinic acid salt may form an ammonium salt or chelate in an amount to inhibit TNF-alpha production to induce apoptosis of white blood cells having a bioassay efficacy using IC50 in HL-60 cell line of approximately 500 micrograms per milliliter or less where application is other than topical.
