Abstract:
The present invention relates to a secretagogue compound derived from oxalate degrading bacteria, for use in the treatment of an oxalate related disease and/or oxalate related imbalance in a subject, wherein the administration of the secretagogue results in a reduction of urinary oxalate and/or plasma oxalate in the subject. The invention further relates to a pharmaceutical composition comprising such a secretagogue compound, a method for treating a subject suffering from an oxalate related disease, and to a method for preparing a secretagogue.
Abstract:
Disclosed is a novel process for producing a serine derivative and an optically active form thereof by a simple procedure. The process comprises the step of reacting an L-α-amino acid represented by the formula (I): (wherein R1 represents a specified hydrocarbon group) with an aldehyde represented by the formula (II): (wherein R2 represents a specified hydrocarbon group) in the presence of a specific enzyme to produce an L-serine derivative represented by the formula (III).
Abstract:
The present invention provides a new method for producing serine derivatives and their optically-activated derivatives in a convenient manner. Under the presence of a given enzyme, an L-α-amino acid of formula (I):
(in the formula (I), R 1 is a given hydrocarbon group) is reacted with an aldehyde of formula (II):
(in the formula (II), R 2 is a given hydrocarbon) to produce an L-serine derivative of formula (III).
Abstract:
The present invention relates to a vitamin B6-coupled gene carrier (vitamin B6 PEA, VBPEA) and to a method for manufacturing the gene carrier. In addition, the present invention relates to a gene carrying complex in which a curing gene is combined with the gene carrier and to a pharmaceutical formulation for gene therapy, including the complex as an active ingredient. Moreover, the present invention relates to gene therapy using the gene carrier, the gene carrying complex or the pharmaceutical formulation including the same. The vitamin B6-coupled gene carrier (VBPEA) according to the present invention has a gene-carrying rate much higher than that of existing gene carriers, has little cytotoxicity when combined with DNA, and has very high in vivo transgenic efficiency. In addition, the vitamin B6-coupled gene carrier (VBPEA) can be used for anticancer treatment as gene silencing efficiency via siRNA is high and the apoptosis of cancer cells and the inhibition of cancer cell proliferation can be induced using the same. Accordingly, the gene carrier according to the present invention can be used widely in a gene therapy field not only as an experimental gene carrier but also for various diseases according to curing genes constituting the same.
