Abstract: A synthetic gene encoding a 71-amino acid analog of human insulin-like grouwth factor (hIGF-I) has been constructed and expressed in the yeast, Saccharomyces cerevisiae. The protein analog, IGF132, contains the first 17 amino acids of the B chain of human insulin in place of the first 16 amino acids of hIGF-I. The purified hybrid protein has high affinity for the type I IGF recepto (12 nM) yet has drastically reduced affinity for human serum carrier proteins (>1000 nM). This analog is 5 to 10 times more active than normal hIGF-I in stimulating DNA synthesis in 3T3 cells and is a more active growth factor in vivo due to its reduced affinity for serum carrier proteins. Other proteins with similar properties have also been constructed.

Abstract: A phenyl derivative of pepstatin A, which is much more potent than pepstatin in inhibiting renin enzyme activity and has significantly greater selectivity for renin over pepsin inhibition than does pepstatin, which is useful in treating hypertension and congestive heart failure.

Abstract: A method is described for treating mammalian solid tumors by administering leukocyte-derived amplifiers of the immune system to tumor-bearing subjects. The amplifiers include Beta-1.0, Beta-1.1, Beta-1,12, TG, and TGG.

Abstract: DNA sequences, recombinant DNA molecules and hosts transformed with them which produce human phospholipase inhibitor-like polypeptides and methods of making and using these products. The DNA sequences and recombinant DNA molecules are characterized in that they code on expression for a human phospholipase inhibitor-like polypeptide. In appropriate hosts these DNA sequences permit the production of human phospholipase inhibitor-like polypeptides useful as anti-inflammatory agents and methods in the treatment of arthritic, allergic, dermatologic, ophthalmic and collagen diseases as well as other disorders involving inflammatory processes.

Abstract: The tripeptide Arg-Lys-Glu, synthetized by conventional solution methods, and its salts display immunostimulating activity both on maturation of immature T cells and on T cell function.

Abstract: A method for the separation or purification of biopolymers comprises adsorbing the biopolymer on the surface of liquid oil droplets; and separating the adsorbed biopolymer from the oil droplets. The adsorbed biopolymer is separated from the oil droplets by mixing the droplets in an aqueous liquid, removing the lower aqueous phase and adding a fresh aqueous phase to the droplets, cooling the mixture to solidify and coalesce the oil and to cause it to release the adsorbed biopolymer to the fresh liquid, separating the fresh liquid and the biopolymer from the coalesced oil, separating the biopolymer from the fresh liquid.

Abstract: The invention relates to selected difluoro compounds of formulae Ia, Ib and Ic ( set out hereinafter) which are useful as inhibitors of human leukocyte elastase.

Abstract: Heptapeptide analogs of somatastatin which inhibit secretion of growth hormone.

Abstract: Novel amino acid derivatives useful as a therapeutic agent are disclosed. These amino acid derivatives and the pharmaceutically acceptable salts thereof have a human renin inhibitory effect when administered orally and are useful for treatment of hypertension, especially renin-associated hypertension.

Abstract: This invention relates to a pharmaceuticals which contains thyroid hormones and improved method which extracts thyroid hormones from animal thyroid gland. The pharmaceuticals of this invention is used to treat senile cortical cataract. There are some effect of long term on other cataract except subcapsular cataract. The pharmaceuticals of this invention is applied in the form of eyedrops or injection.

Abstract: Substantially pure, synthetic peptides corresponding to specific epitopic sites of various G-proteins and antibodies having binding affinity specifically for said epitopic sites have been prepared. Kit and method for identifying various G-proteins are also disclosed.

Abstract: A method of treating osteoporosis, especially post-menopausal osteoporosis, by administering on a periodic but regular basis to a patient growth hormone releasing factor, GRF(1-44)-NH.sub.2, or a biologically active analog thereof, and continuing the administration until bone mass increases and the patient's calcium balance becomes positive and indicates a mineral accumulation in the skeleton.

Abstract: A method of increasing the modulus of elasticity of a biopolymer is disclosed, which comprises incorporating a hexameric unit of the formula--X--(APGVGV).sub.n --Y--whereinA is a peptide-forming residue of L-alanine;P is a peptide-forming residue of L-proline;G is a peptide-forming residue of glycine;V is a peptide-forming residue of L-valine;X is PGVGV, GVGV, VGV, GV, V, or a covalent bond;Y is APGVG, APGV, APG, AP, A, or a covalent bond; andn is an integer from 2 to 200, wherein said hexameric unit comprises at least 18 amino acid residues, into an elastomeric polypeptide chain.
