Abstract: The present invention relates to a process for the preparation of activated polyethylene glycols, or PEG(NPC)2s, comprising reacting polyethylene glycol with an activator while in the presence of an aromatic nitrogen containing heterocyclic base. The process is carried out at temperatures ranging from about 20 to about 30° C., more preferably at room temperature, and under stoichiometric conditions.

Abstract: The present invention relates to chimeric fatty body-pro-GRF analogs with increased biological potency, their application as anabolic agents and in the diagnosis and treatment of growth hormone deficiencies. The chimeric fatty body-pro-GRF analogs include an hydrophobic moiety (tail), and can be prepared, either by anchoring one or several hydrophobic tails to the GRF, or by substituting one or several amino-acids by a pseudomicellar residue in the chemical synthesis of GRF. The GRF analogs of the present invention are biodegradable, non-immunogenic and exhibit an improved anabolic potency with a reduced dosage and prolonged activity.

Abstract: The present invention relates to a pharmaceutical composition for improving penile rigidity and/or preventing erectile dysfunction, including premature ejaculation, of a male mammal patient which comprises at least one of seeds from Aframomum species, its closely related species and remote ancestors thereof, mixture thereof and extracts thereof. The pharmaceutical composition may further comprise a pharmaceutically acceptable carrier for topical or oral administration.

Abstract: The present invention relates to a process for the preparation of porcine platelet-extract containing matured growth factors, which comprises the steps of: a) centrifuging whole porcine blood at about 1000 g to about 5000 g to isolate the platelets from the platelet-rich-plasma; b) resuspending the isolated platelets of step a) in Plasma-Lyte A and centrifuging to concentrate the platelets; c) washing the concentrated platelets of step b); d) lyophilizing the washed platelets of step c); whereby causing lysis of the platelets and producing the platelet extract in optimal amount.

Abstract: The present invention relates to a long-acting galenical formulation of GRF peptides, pro-GRF and/or analogs thereof which comprises about 1 to about 100 mg of a GRF peptide, fragment or analog thereof pressed from about 1 to about 100 kg/mm.sup.2 in a tablet for parenteral administration, whereby these GRF peptides are released as the tablet is eroded.

Abstract: The present invention relates to a process for preparing peptide synthons in which the optical purity of each of the peptides to be condensed is retained.According to this process, a silyl derivative of an amino acid or peptide, which is activated by a complex chloroimmonium salt, a complex coordinated phosphorus halide, oxyhalide salt or a complex oxalyl halide salt, is prepared. The activated peptide is then condensed with an N-silyl amino acid or peptide in which the acid group is protected.
