    Abstract: The invention relates to N-heterocyclic substituent-containing antibiotics, their preparation, and their use. Disclosed are sodium and potassium salts of 7-(α-((N,N′-diisopropylamidino)thio)acetylamino)-3-(((1,2,5,6-tetrahydro-2-methyl-5,6-dioxo-1,2,4-triazin-3-yl)thio)methyl) cephalosporanic acid as presented by the general structure (I), their preparation, and their use. The antibiotics of the invention can be used to treat diseases caused by Gram-positive or Gram-negative bacteria such as septicaemia, gastrointestinal tract infection, and urinary tract infection. They have increased half-life in blood and lowered toxicity. They can reduce the frequency of drug use and lower medical treatment costs. They have improved stability and can be stored at ambient temperatures. The method of the invention is simple, and it produces high purity products which can meet the requirements of clinical use.

    Abstract: The present invention provides compositions and methods for generating and cryopreserving dendritic cells with superior functionality in producing stronger signals to T cells, resulting in a more potent DC-based anti-tumor vaccine. The present invention includes mature, antigen loaded DCs activated by Toll-like receptor agonists that induce clinically effective immune responses, preferably when used earlier in the disease process. The DCs of the present invention produce desirable levels of cytokines and chemokines, and further have the capacity to induce apoptosis of tumor cells. The cells can be cryopreserved and thawed for later use, thereby reducing the need for repeated pheresis and elutriation processes during vaccine production. These methods can also be utilized to directly target molecules involved in carcinogenetic signaling pathways and cancer stem cells.
