A general procedure for mild and rapid reduction of aliphatic and aromatic nitro compounds using ammonium formate as a catalytic hydrogen transfer agent
(Elsevier, 1984)
Various aliphatic and aromatic nitro compounds were selectively and rapidly reduced to their corresponding amino derivatives in very good yield using anhydrous ammonium formate as a catalytic hydrogen transfer agent.
A chemical approach to solving bridging phenomena in steroid radioimmunoassays
(Elsevier, 1981-08)
Steroid radioimmunoassays (RIA) employ antibodies raised against a carrier protein-steroid conjugate. Individual antibodies may recognize the steroid, the protein or the chemical bridge used to Join them together. Use of ...
Regional processing of the N- and C-terminal domains of proopiomelanocortin in monkey pituitary and brain
(Elsevier, 1988-04)
The total content and extent of processing of the [gamma]3MSH and [beta]-endorphin-containing N- and C-terminal domains of proopiomelanocortin were determined in the anterior and intermediate lobes of the pituitaries and ...
A reagent for covalently attaching biotin to proteins via a cleavable connector arm
(Elsevier, 1982-10-01)
The preparation of a reagent which can be used to attach biotin to proteins via a cleavable connector arm is described. The reagent, 3-(4-(N-biotinoyl-6-aminocaproyloxy)phenyl)propionic acid N-hydroxysuccinimide ester ...
A practical large scale chemical synthesis of chiral glycines
(Elsevier, 1988)
(R)- and (S)-[2-2H]glycine of high chiral purity were synthesized in large quantities in [approximate] 40% overall yield from readily available starting materials via a totally chemical procedure. Reduction of either ...
High-performance liquid chromatographic determination of ibuprofen and its major metabolites in biological fluids
(Elsevier, 1982-11-12)
A sensitive and selective high-performance liquid-chromatographic assay for ibuprofen and its major metabolites in biological fluids is described. To ensure good chromatographic separation the drug and metabolites were run ...
Determination of the glucosidase-stimulating proteins by competitive enzyme-linked immunoassay
(Elsevier, 1984-10)
A procedure for the immunoassay of cohydrolase sphingolipid-I in mouse tissue is described. This cohydrolase (actually a mixture of at least four related proteins) stimulates or activates the [beta]-glucosidase which ...
Mitoxantrone, cisplatin, and methyl-glyoxal bis-guanylhydrazone chemotherapy for refractory malignant lymphoma: A Southwest Oncology Group phase II trial
(Kluwer Academic Publishers; Springer Science+Business Media, 1989-07)
A phase II trial of combination chemotherapy with mitoxantrone, cisplatin, and methyl-glyoxal bix-guanylhydrazone (MGBG) was conducted in 32 patients with unfavorable histology malignant lymphoma. All patients had relapsed ...
Gas chromatographic determination of gallopamil and norgallopamil in human plasma
(Elsevier, 1989)
A highly sensitive gas chromatographic assay is described for the simultaneous determination of gallopamil, a calcium channel blocking agent, and its major metabolite, norgallopamil. A multi-step extraction procedure is ...
