Acylfulvene analogs, which inhibit tumor growth, especially solid tumor growth, and which have an adequate therapeutic index to be effective for in vivo treatment are provided herein. The compounds described herein are useful as anti-neoplastic agents, i.e., to inhibit tumor cell growth in vitro or in vivo, in mammalian hosts, such as humans or animals, e.g., domestic animals, and are effective against solid tumors, hematologic malignancies and multi-drug resistant cancers/tumors. The present compounds can be used alone or they can be used in combination with one or more anti-cancer or anti-tumor agents.

The invention provides methods for loading a preservative into blood platelets comprising providing a preservative solution having a preservative, water and protein, and loading blood platelets with the preservative solution to produce preservative-loaded blood platelets having the preservative solution generally including higher glass transition temperatures than glass transition temperatures for a preservative solution having the preservative, water and no protein. A process for processing blood platelets comprising suspending blood platelets in a preservative solution at a concentration greater than about 108 platelets per ml. of preservative solution to produce preservative-loaded blood platelets, freeze-drying the preservative-loaded blood platelets, and recovering at least 75% of the freeze died platelets. A platelet composition comprising blood platelets loaded with a preservative solution having a preservative, water, and protein, and generally further having higher glass transition temperatures than glass transition temperatures for blood platelets loaded with the preservative, water, but no protein.
摘要:
A method of forming supported group 4, and/or 5, and/or 6 metal clusters, which may be used as a catalyst for alkane reactions. The method includes combining a solid support and a precursor compound of group 4, 5, or 6 metals, or precursor compounds of group 4, and/or 5, and/or 6 metals, or a precursor compound of a combination of group 4, 5, and/or 6 metals, and combinations thereof; and optionally treating the combination to form the supported group 4, and/or 5, and/or 6 clusters. The material formed by the combination of the precursor or precursors with a solid support following an optional treatment can be used as a catalyst for disproportionation of alkanes and/or conversion of one or more alkanes with another alkane or other alkanes by contacting the material with the alkanes.
摘要:
The present invention provides novel receptor-binding cyclic peptides that advantageously display high receptor binding affinity and selectively. More particularly, the present invention provides integrin-binding cyclic peptides containing an integrin-binding motif such as an RGD motif, an aromatic amino acid such as a tyrosine residue, and a lysine residue having a pi-pi stacking moiety conjugated to its ε-amino group. Methods for identifying receptor-binding cyclic peptides and for using the cyclic peptides of the present invention for imaging a tumor, organ, or tissue and for treating cancer, inflammatory diseases, and autoimmune diseases are also provided.
摘要:
Provided are peptides, peptide analogs, and peptide mimetics that inhibit HIV activity, pharmaceutical compositions comprising such peptides and peptide analogs, and methods of inhibiting HIV activity and/or transmission by administering the peptides and peptide analogs to a subject.
摘要:
The present invention provides a mutant antibody comprising a reactive site not present in the wild-type of the antibody and a antigen recognition domain that specifically binds to a metal chelate, wherein the reactive site is in a position proximate to or within the antigen recognition domain.

This invention provides approaches to improve the signal to noise ratio (S/N) in electrochemical measurements (e.g. amperometry, voltammetry, etc.). In particular, a method is described wherein the faradaic current is temporally dissociated from the charging current associated with reading the charge of a redox-active species (e.g. a self-assembled monolayer (SAM)). This method, designated herein as open circuit potential amperometry (OCPA), quantitatively reads the charge of the redox species bound to (electrically coupled to) an electrode surface, while discriminating against both charging current(s) and amperometric signal(s) that arise, e.g. from diffusion-based species in solution.
摘要:
Anion exchange resins including at least two positively charged sites and aell-defined spacing between the positive sites are provided together with a process of removing anions or anionic metal complexes from aqueous solutions by use of such resins. The resins can be substituted poly(vinylpyridine) and substituted polystyrene.
