PURPOSE: A novel imidazolylalkylcarbonyl derivative which is effective as calcium ion channel regulator is provided to effectively block T-type calcium ion channel, prevent and treat brain diseases, heart diseases and pain. CONSTITUTION: An imidazolylalkylcarbonyl derivative is denoted by chemical formula 1. The imidazolylalkylcarbonyl derivative of chemical formula 1 is prepared by performing amide bond of piperazine derivative of chemical formula 3 with imidazolylalkylcarboxylic acid of chemical formula 2. The amide bond is performed using binder selected from phosphonium system, ammonium system, carbodiimide system, imidazolinium, and organic phosphine system. A method for preparing the imidazolylalkylcarboxylic acid of chemical formula 2 comprises: a step of performing hetero-michael addition reaction of ethy alkenoate with imidazole compound under the presence of KF/Al2O3 catalyst to produce ethoxycarbonylalkylimidazole compound of chemical formula 2a; and a step of hydrolyzing the ethoxycarbonylalkylimidazole compound of chemical formula 2a to prepare imidazolylalkylcarboxylic acid of chemical formula 2.

Abstract:
PURPOSE: Provided is a chitosan composite containing a hydrophobic group, which can encapsulate various hydrophobic pharmaceuticals and therapeutic proteins to give excellent biocompatibility and biodegradability, and thus is useful for pharmaceutical carrier. CONSTITUTION: The chitosan composite containing a hydrophobic group forms a nanosized self-aggregate in aqueous solution. Particularly, an amino group of chitosan is coupled with a carboxyl group of hydrophobic bile acid to form a nanosized self-aggregate. The chitosan is selected from the group consisting of water soluble glycol chitosan, chitosan oligomer and 50%-acetylated chitosan. The hydrophobic bile acid is selected from the group consisting of cholic acid, chenodeoxycholic acid, deoxycholic acid, lithocholic acid, 7-oxo-lithocholic acid and 5-beta-cholanic acid.
Abstract:
PURPOSE: A process of preparing a fat emulsion using oils having higher specific gravity than water as a fat emulsion base material and amphoteric surfactants as an emulsifier is provided. The fat emulsion exhibits excellent expression efficiency in adhesive cell lines as well as in the presence of serum as compared to conventional liposome or squalane-based fat emulsion formulation and thus permits easy in-vitro assay of gene expression efficiency. CONSTITUTION: A fat emulsion comprises: 2 to 30% by weight of oil mixtures comprising iodized oil and one or more glyceride-based oils such as squalene or squalane as a fat emulsion base; 0.01 to 40% by weight of one or more amphoteric surfactants; 0.01 to 10% by weight of hydrophilic polymers, phospholipid combined with hydrophilic polymers or polymerizable phospholipid; 0.01 to 10% by weight of glycerol, soluble peptide or soluble protein; and the balance comprising water. The oil mixtures contain 40% by weight of iodized oil selected from the group consisting of iodized poppy seed oil.
