摘要:
A photoresist composition which includes hydroxycarborane either incorporated as a monomeric dissolution modifier or as pendent groups on a polymer backbone. The photoresist composition is particularly useful in a bilayer thin film imaging lithographic process in which ultraviolet radiation-imaging in a wavelength range of between about 365 nm and about 13 nm is employed.

Provided is a method for polymerizing a polymer precursor, comprising: contacting a polymer precursor with a lithium carborane catalyst and an initiator under polymerizing conditions. A reaction solvent may be used, but is not necessary. Also provided is a method of preparing lithium carborane polymers, comprising: contacting a lithium carborane polymer precursor having a terminal alkenyl or alkynyl group with an initiator and an optional reaction solvent under polymerizing conditions.

The present invention is directed to an antigen found on the surface of rat and human pancreatic cancer cells and provides antibodies of high specificity and selectivity to this antigen as well as hybridomas secreting the subject antibodies. Methods for both the diagnosis and treatment of pancreatic cancer are also provided. This tissue marker of pancreatic adenocarcinoma, an approximately 43.5 kD surface membrane protein designated PaCa-Ag1, is completely unexpressed in normal pancreas but abundantly expressed in pancreatic carcinoma cells. Moreover, a soluble form of PaCa-Ag1 exists, having a molecular weight about 36 to about 38 kD, that is readily identified in sera and other body fluids of pancreatic cancer patients, using a subject antibody.
摘要:
Substituted borate and carborate anions having unusual properties of being exceptionally weakly nucleophilic and being soluble in non-polar solvents. One-electron oxidation of the anions yields the corresponding radicals. The compounds are useful, e.g., as electrolytes, catalysts, and electrochromic materials.
摘要:
The present invention provides peptides (including analogs and derivatives thereof) corresponding to residues 96-110 and 35-47 of ras-p21, which peptides have attached thereto a membrane-penetrating leader sequence. The subject peptides, analogs and derivatives thereof are useful in treatment of cancers and have been shown to induce phenotypic reversion of pancreatic cancer cells to non-cancerous cells. Pharmaceutical compositions comprising one or more subject peptides are also provided by the present invention. The present invention further provides replication incompetent Adenovirus (AdV) vectors comprising a promoter sequence and a nucleotide sequence encoding a subject peptide. Methods of treating cancer by administering one or more subject peptides, pharmaceutical compositions, and/or AdV vectors are also provided.

摘要:
This invention relates to an improved method for making unsubstituted carborane anions and monosubstituted carborane anions of formula: (R—CBn—Hm′)− where n is an integer ranging from 5 to about 11 and m′ is an integer ranging from 5 to 16 where the relative values of n and m′ depend upon the exact structure of the carborane and the presence of a non-hydrogen substituent. m as used herein is an integer ranging from 5 to 16. When R is hydrogen the anion is unsubstituted. When R is a halogen, a phenyl, a substituted phenyl group, such as fluorophenyl group, or any other substituent, the carborane is substituted. The method is particularly useful for preparation of twelve-vertex carborane anions R—CB11H11−, where R is a defined above, and is specifically useful for preparation of the unsubstituted carborane CB11H12-??, where R is H.

摘要:
The present invention provides peptides corresponding to all or a portion of amino acid residues 12-26 of human p53 protein, which peptides are lethal to malignant or transformed cells when fused to a membrane-penetrating leader sequence. The subject peptides are thus useful in treating neoplastic disease in an animal, preferably a human. Also provided are pharmaceutical compositions comprising the subject peptides admixed with a pharmaceutical acceptable carrier. Methods of treating neoplastic disease in a patient by administering a subject peptide fused at its carboxy terminal end to a membrane penetrating leader sequence are also provided. The present invention also provides replication incompetent Adenovirus (AdV) vectors comprising a promoter sequence operably linked to a nucleotide sequence encoding a subject peptide. Methods of selectively killing cancer cells in a subject by administering a therapeutically effective amount of a subject AdV vector are also provided by the present invention.
