Patent number: 8252341Abstract: The present invention concerns a novel process for isolating growth and differentiating factors present in colostrum, all in a natural way. This process is characterized by maturation steps (controlled mild acid hydrolysis) and physical steps (molecular filtration) which optimize recovery of measured growth factors and their ability to entice a response on human cells. Advantageously, this process allows the derivation and isolation of growth and differentiating factors with highly disparate sizes (or molecule weights) in pools. These pools can be used in select and varied ways, including cosmetic, cosmeceutical, nutraceutical, dermatological, pharmaceutical, medical and veterinary applications. It can also be used as a replacement to fetal calf serum to promote cell proliferation, and above all, cell differentiation.Type: GrantFiled: September 14, 2005Date of Patent: August 28, 2012Inventor: Paul Brazeau

Publication number: 20040171534Abstract: The present invention relates to chimeric fatty body-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-GRF analogs include an hydrophobic moiety (tail), and can be prepared, either by anchoring at least one hydrophobic tail to the GRF, 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.Type: ApplicationFiled: August 7, 2002Publication date: September 2, 2004Applicant: Theratechnologies, Inc.Inventors: Denis Gravel, Abdelkrim Habi, Paul Brazeau

Publication number: 20040081703Abstract: The present invention relates to cartilage extracts and to a method of producing the same. Shark cartilage extracts having anti-angiogenic, anti-tumor, anti-inflammatory and anti-collagenolytic activities have been obtained by an improved process. The process comprises the steps of obtaining a crude cartilage extract in an aqueous solution, this crude extract being fractionated to recover molecules of a molecular weight less than about 500 kDa. Some of the biologically active components of the extract are prepared by further fractionation. The cartilage extract can be used for treating diseases or conditions having etiological components selected from the group consisting of tumor proliferation, angiogenesis, inflammation, metalloprotease activity and collagenolysis. Several cosmetic applications based on the capacity of the liquid extract to improve skin conditions are also disclosed. A simple and efficient process for the preparation of cartilage extracts is also disclosed.Type: ApplicationFiled: October 17, 2003Publication date: April 29, 2004Applicant: Les Laboratoires Aeterna, Inc.Inventors: Eric Dupont, Paul Brazeau, Christina Juneau, Daniel H.

Patent number: 6028118Abstract: The present invention relates to cartilage extracts and to a method of producing the same. Shark cartilage extracts having anti-angiogenic, anti-tumoral, anti-inflammatory and anti-collagenolytic activities have been obtained by an improved process. The process comprises the steps of obtaining a homogenate of cartilage in an aqueous solution, this homogenate being separated in a solid fraction (SOLID EXTRACT) and a liquid fraction which was further fractionated to obtain a LIQUID EXTRACT having molecules of a molecular weight comprised between 0 to 500 kDa. The composition of the liquid extract has then been investigated by different ways. Further fractionation of this extract led to the preliminary characterization of some of its active components.Type: GrantFiled: August 8, 1996Date of Patent: February 22, 2000Assignee: Les Laboratoires Aeterna Inc.Inventors: Eric Dupont, Paul Brazeau, Christina Juneau, Daniel H.

Patent number: 6025334Abstract: The present invention relates to cartilage extracts and to a method of producing the same. Shark cartilage extracts having anti-angiogenic, direct anti-tumor proliferating, anti-inflammatory and anti-collagenolytic activities have been obtained by an improved process. The process comprises the steps of obtaining a homogenate of cartilage in an aqueous solution, this homogenate being centrifuged and further fractionated to obtain a total extract having molecules of a molecular weight comprised between 0 to 500 KDa. The composition of the liquid extract has then been investigated by different ways. Further fractionation of this extract led to the preliminary characterization of some of its active components. Due to the multiplicity of biological activities of the total liquid extract, it can be used for treating numerous diseases or conditions such as those having components selected from the group consisting of tumor proliferation, angiogenesis, inflammation and collagenolysis.Type: GrantFiled: October 30, 1995Date of Patent: February 15, 2000Assignee: Les Laboratoires Aeterna Inc.Inventors: Eric Dupont, Paul Brazeau, Christina Juneau, Daniel H.

Patent number: 5985839Abstract: The present invention relates to shark cartilage extracts and to a method of producing the same, these extracts having anti-angiogenic properties (reduction of the area of blood vessels observed in vivo on experimentally induced tumors), tumor regressive activity in vivo as well as demonstrating a direct inhibitory effect on tumor cell lines. This process does not involve any denaturing solvent or product and does not involve the use of any enzymes. It consists of obtaining a blend of whole cartilage in an aqueous solution of neutral pH, preferably pure water, this blend being centrifuged and the pellet and supernatant kept for further processing. The pellet is lyophilized and tested for anti-tumor and anti-angiogenic activities in vivo and in vitro, with or without supernatant. The supernatant has been shown to have anti-angiogenic and tumor regressive activities in vivo. The composition of the supernatant has then been investigated by different ways.Type: GrantFiled: October 8, 1996Date of Patent: November 16, 1999Assignee: Les Laboratories Aeterna Inc.Inventors: Eric Dupont, Paul Brazeau, Christian Juneau

Patent number: 5939386Abstract: 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.Type: GrantFiled: August 23, 1996Date of Patent: August 17, 1999Assignee: Theratechnologies Inc.Inventors: Michel Ibea, Thierry Abribat, Paul Brazeau
