Abstract: The present invention relates to methods for the detection of polymorphism in polynucleotides by using hybridization of fragments of segments of a polynucleotide suspected of containing a polymorphism with an oligonucleotide having a sequence complementary to a fragment identifying the polymorphism and subsequent detection of incorporated labels in the oligonucleotide-fragment duplex.

Abstract: The present invention relates to a cephem prodrug having formula III or formula IV: or a pharmaceutically acceptable salt thereof, wherein R′1 is selected from the group consisting of hydrogen and —C(O)CH(NH2)CH3 and R′2 is selected from the group consisting of hydrogen and an acyl group that is cleaved by an enzyme found in mammals, with the proviso that, when either R′1 or R′2 is hydrogen, the other is not. A, B, L, G, E, and J are each independently nitrogen or carbon such that the respective rings are selected from the group consisting of provided that the group —CH2—S—CH2CH2NHR′2 is attached only to a carbon atom of said heterocyclic group, and Q is selected from the group consisting of nitrogen and —CX, wherein X is selected from the group consisting of hydrogen and chlorine.

Abstract: The present invention relates to purified platinum complexes in which platinum is coordinated to form a single N,O- or O,O-chelate of an amidomalonate. The chelates, and pharmaceutically acceptable formulations thereof, are useful for the treatment of cancer. The platinum chelates may additionally be linked to one or more functional groups which increases water solubility and/or assists in tumor targeting of the chelate. Examples of tumor targeting moieties include polymers, in which one or more platinum chelates are attached to the polymer backbone via linkers capable of being cleaved in the body, and molecules with a high affinity for receptors which are concentrated or upregulated in tumor tissue and/or the tumor vasculature.

Abstract: This disclosure describes isolated or purified deoxyribonucleotide (DNA) sequences, useful for the development of antibacterial agents, which contain the coding sequences of bacterial pathogenesis genes or essential genes, which are expressed in vivo. It further describes isolated or purified DNA sequences which are portions of such bacterial genes, which are useful as probes to identify the presence of the corresponding gene or the presence of a bacteria containing that gene. Also described are hypersensitive mutant cells containing a mutant gene corresponding to any of the identified sequences and methods of screening for antibacterial agents using such hypersensitive cells. In addition it describes methods of treating bacterial infections by administering an antibacterial agent active against one of the identified targets, as well as pharmaceutical compositions effective in such treatments.
