  • Patent number: 7968311
    Abstract: Expression systems are disclosed for the direct expression of peptide products into the culture media where genetically engineered host cells are grown. High yield was achieved with novel vectors, a special selection of hosts, and/or fermentation processes which include careful control of cell growth rate, and use of an inducer during growth phase. Special vectors are provided which include control regions having multiple promoters linked operably with coding regions encoding a signal peptide upstream from a coding region encoding the peptide of interest. Multiple transcription cassettes are also used to increase yield. The production of amidated peptides using the expression systems is also disclosed.

  • Patent number: 7776826
    Abstract: A method of inducing bone formation in a subject in need of such inducement comprises the steps of mechanically inducing an increase in osteoblast activity in the subject and elevating blood concentration of at least one bone anabolic agent in the subject. The method steps may be performed in any order, but in sufficient time proximity that the elevated concentration of the anabolic agent and the mechanically induced increase in osteoblast activity overlaps. The method may additionally comprise providing the subject with an elevated blood concentration of at least one antiresorptive agent, wherein the elevated concentration is sufficient to prevent resorption of new bone growth produced due to the osteoblast activity. Use of the method permits targeting of specific bones of the subject for bone production and preservation, faster bone production and earlier discontinuation of bone anabolic pharmaceuticals. Kits adapted for performing the method are provided.

  • Publication number: 20090023892
    Abstract: Conversion in vitro of X-Gly to X-alpha-hydroxy-Gly or X-NH2 (X being a peptide or any other compound having a carbonyl group capable of forming a covalent bond with glycine) is accomplished enzymatically in the presence of keto acids, or salts or esters thereof, to provide a good yield without the necessity of catalase or similar enzymatic reaction enhancers. Peptidylglycine ?-amidating monooxygenase (PAM) is a preferred enzyme for catalyzing the conversion. Alternatively, peptidylglycine ?-hydroxylating monooxygenase (PHM) is utilized to convert X-Gly to X-alpha-hydroxy-Gly which may be recovered, or optionally may be simultaneously or sequentially converted to an amide by either a Lewis base or action of the enzyme peptidyl ?-hydroxyglycine ?-amidating lyase (PAL). Both PHM and PAL are functional domains of PAM.

  • Publication number: 20080213333
    Abstract: A method for augmenting bone in a subject in need thereof including installing within an interior portion of a bone located in the subject a sufficient amount of a biocompatible material to form a scaffold within the bone interior, wherein the scaffold serves as a support for the formation of new bone within the bone interior portion, and administering to the subject a sufficient amount of at least one bone augmentation agent to elevate blood concentration of at least one anabolic agent in the subject. The method may further include administering at least one anti-resorptive agent to the subject in an amount sufficient to substantially prevent resorption of new bone growth. In another embodiment, the method may further include a step of mechanically inducing an increase in osteoblast activity in the subject, wherein the elevation in blood concentration of the anabolic agent and the increase in osteoblast activity at least partially overlap in time.

  • Patent number: 6673574
    Abstract: Bioavailability of peptide active agents to be administered orally is enhanced by a pharmaceutical composition providing targeted release of the peptide to the intestine in addition to having the active peptide linked to a membrane translocator which is capable of being at least partially cleaved in vivo by an enzyme. The composition includes an acid-resistant protective vehicle which transports components of the invention through the stomach and a sufficient amount of a pH-lowering agent to lower local intestinal pH. All components are released together into the intestine with the peptide.
