Previous reports from this laboratory demonstrated the synthesis of hyaluronic acid by a cell-free preparation obtained from a strain of Group A streptococcus. The enzymic activity which sedimented at 105,000 x g, but not at 10,000 x g, required the addition of uridine diphospho-N-acetylglucosamine, uridine diphosphoglucuronic acid, and Mg++ for the formation of hyaluronic acid (l-3). Since hya...

that folic acid antagonists provide temporary palliation in certain cases of acute leukemia in children (7) and that several compounds of this class increase the survival time of mice with transplanted leukemia Ak 4 (4, 10, 11). However, eventual failure in the treatment of leukemia by chemotherapy with such compounds occurs consistently. The mechanism involved in the development of drug resist...

Caffeic acid (CA; 3,4-dihydroxycinnamic acid) is endowed with high antioxidant activity. CA derivatives (such as amides) have gained a lot of attention due to their antioxidative, antitumor and antimicrobial properties as well as stable characteristics. Caffeoyl-peptide derivatives showed different antioxidant activity depending on the type and the sequence of amino acid used. For these reasons...
