Abstract:
This invention features a dipyrazolo-pyridine compound of formula (I): each of R1, R2, R3, and R4, independently, is H, alkyl, alkenyl, cycloalkyl, aryl, or heteroaryl; and each of R5 and R6, independently, is aryl or heteroaryl, or R5 and R6, together with the N atom they are attached to, are heteroaryl. The dipyrazolo-pyridine compound can be used in an electro-luminescence device.
Abstract:
The present invention provides a process of producing highly purified proteases. The invention further provides the use of such purified proteases in treating cardiovascular disorders, including hypertension, stroke and thrombosis.
Abstract:
The present invention provides an antimicrobial peptide, monodoncin, which is isolated and purified from Penaeus monodon and is capable of being mass produced by molecular cloning techniques in a heterologous expression system, such as yeast. Monodoncin demonstrates a wide-range of bacteriostatic and bactericidal effects on G(null) and G(null) bacteria as well as fungicidal activities, and can be used in combination with conventional antibiotics as nullcocktail therapynull to improve the therapeutic effects of the conventional antibiotics.
Abstract:
A novel anti-polyethylene glycol monoclonal antibody and its preparation are disclosed. Such an antibody can be used for determining polyethylene glycol concentration in vitro or accelerating the clearance of a polyethylene glycol containing compound from the blood circulation in the human body thereby reducing the toxicity associated with the polyethylene glycol containing conjugate. The antibody is particularly useful in cancer therapy where the therapeutic agent is selectively delivered to the tumor by increasing the tumor/blood ratio of the polyethylene glycol containing compound.
Abstract:
A process for producing L-homophenylalanine comprises the step of reacting 2-oxo-4-phenylbutyric acid with a L-amino acid in the presence of tyrosine aminotransferase in a reaction solution to produce L-homophenylalanine.
Abstract:
The present invention relates to the establishment of an immortal shrimp cell line (PMO) derived from Penaeus monodon. This cell line is susceptible to and capable of mass producing virus, which includes, but not limited to, white spot syndrome virus (WSSV), Panaeus monodon baculovirus (MBV), infectious hypodermal and hematopoietic necrosis virus (IHHNV), and infectious pancreatic necrosis virus (IPNV). This invention also relates to the method of mass producing virus using PMO as a host.
Abstract:
The present invention relates to the finding and construction of fish insulin-like growth factor II (IGF-II) cDNAs which can be cloned and expressed in cells. This invention also relates to the production of biologically active fish IGF-II polypeptides by a gene expression system using fish IGF-II cDNAs. The fish IGF-II cDNAs have 1977 bp which transcribe into a prepeptide (signal peptide), and B, C, A, D, E domain peptides. The fish mature IGF-II is a single polypeptide containing the NH.sub.2 -B-C-A-D-COOH domains. The mature IGF-II polypeptide is 7 kDa in weight and has 70 amino acids. The fish recombinant IGF-II CDNA can be cloned and expressed in E. coli, yeast, baculovirus, and fish cells.
Abstract:
This invention relates to amphipathic protein-1 polypeptides and genes encoding them. The amphipathic protein-1 polypeptides of the invention protect plants from tissue damage caused by the hypersensitive response, which is often elicited by bacterial infection in higher plants.
Abstract:
Polypropylene microporous films characterized by having a porosity of 30-35%, an average pore size of 200-800 Angstroms, a permeation coefficient for nitrogen of 1-5.times.10.sup.-3 ml/cm sec atm and a tensile strength of greater than 60 MPA in all directions within the film plane are prepared by the consecutive steps of biaxial stretching a non-porous starting film of high .beta.-crystal content and heat setting the stretched film.
