Monoazole ligand platinum analogs

Disclosed herein are novel platinum-based analogs with a single substituted azole ligand: RN═NR7, wherein the RN═NR7 functional group is covalently bonded to the platinum through nitrogen of NR7. The analogs also have nitrogen donor ligands capable of forming hydrogen bonds with the bases in DNA or RNA, and one or more leaving groups which can be displaced by water, hydroxide ions or other nucleophiles, which is thought to form active species in vivo, and then, form cross-linked complexes between nucleic acid strands, principally between purines in DNA (or RNA), i.e., at the Guanine or Adenine bases, thereof. These platinum analogs may also be more easily transported into tumor cells, due to their increased lipophilicity and are likely to be useful as anti-neoplastic agents, and in modulating or interfering with the synthesis or replication or transcription of DNA or translation or function of RNA in vitro or in vivo, as they are potentially capable of forming a platinum coordinate complex with an intact or nascent DNA or RNA and thereby interfering with cellular synthesis, transcription or replication of nucleic acid polynucleotides.

Method for synthesis of D-psicose by aldolase whole cell

The invention discloses a method for synthesis of D-psicose by microbiological fermentation, specifically a method for synthesis of D-psicose by aldolase whole cell. The method includes: firstly constructing recombinant corynebacterium glutamicum SY12 carrying L-fucose-1-phosphate aldolase gene and fructose-1-phosphorylase gene (i.e. with aldehyde condensation approach), then adding glucose and D-glyceraldehyde into a basic salt medium, synthesizing dihydroxyacetone phosphate from glucose by means of intracellular glycolysis, synthesizing a single product D-psicose from D-glyceraldehyde and dihydroxyacetone phosphate (DHAP) under the action of the L-fucose-1-phosphate aldolase and fructose-1-phosphorylase carried by the corynebacterium glutamicum recombinant strain SY12, with the conversion rate of D-glyceraldehyde being 53%. Therefore, compared with the existing method for in vitro synthesis of D-psicose by ketose3-epimerase, the biosynthesis method of D-psicose provided by the invention has the advantages of high conversion rate, single product, easy separation and the like, and lays certain foundation for mass production of D-psicose.

Method and apparatus to identify small variations of biomolecules

Many diseases are related to variations in the genetically specified structure of proteins synthesized by cells. Genetic engineering is now able to identify the structural variations and to introduce new genes to synthesize more healthful proteins, but it is difficult actually to identify the specific protein or chemical variants in bodily fluids and extracts of tissues in order to diagnose diseases and to assess the effects of treatment. This invention provides apparatuses and methods which allow a user to finely discriminate between small variations in the structure, function and levels of specific biochemicals even when admixed with other biochemicals.

Near-Infrared electromagnetic modification of cellular steady-state membrane potentials

Systems and methods are disclosed herein for applying near-infrared optical energies and dosimetries to alter the bioenergetic steady-state trans-membrane and mitochondrial potentials (ΔΨ-steady) of all irradiated cells through an optical depolarization effect. This depolarization causes a concomitant decrease in the absolute value of the trans-membrane potentials ΔΨ of the irradiated mitochondrial and plasma membranes. Many cellular anabolic reactions and drug-resistance mechanisms can be rendered less functional and / or mitigated by a decrease in a membrane potential ΔΨ, the affiliated weakening of the proton motive force Δp, and the associated lowered phosphorylation potential ΔGp. Within the area of irradiation exposure, the decrease in membrane potentials ΔΨ will occur in bacterial, fungal and mammalian cells in unison. This membrane depolarization provides the ability to potentiate antimicrobial, antifungal and / or antineoplastic drugs against only targeted undesirable cells.

Materials and methds to enhance hematopoietic stem cells engraftment procedures

This disclosure is directed to the methods of enhancing hematopoietic stem cells (HSPC) and progenitor cell (HSPC) engraftment procedure. Treatment in vivo of a HSPC donor with compounds that reduce PGE2 biosynthesis or PGE2 receptor antagonists alone, or in combination with other hematopoietic mobilization agents such as AMD3100 and G-CSF, increases the circulation of available HSPCs. Compounds that reduce the cellular synthesis of PGE2 include non-steroidal anti-inflammatory compounds such as indomethacin. Treatment ex vivo of HSPC with an effective amount of PGE2 or at least one of its derivatives such as 16,16-dimethyl prostaglandin E2 (dmPGE2), promotes HSPC engraftment. Similar methods may also be used to increase viral-mediated gene transduction efficacy into HSPC.
