Abstract: Disclosed is a method for preparing a mixed formulation of sustained release microspheres with various compositions by a continuous one-step process. The present method is characterized by preparing the mixed formulation of sustained release microspheres with different compositions by a continuous one-step process by continuously introducing the mixed fluids into a dryer from the two or more different fluids for preparation of sustained release microspheres containing a biodegradable polymer, a drug, an additive and a solvent with different types of contents or both of the components, by controlling the mixing ratios of the fluids according to the time, unlike a conventional method including spray-drying a mixture of microspheres containing a biodegradable polymer, a drug, an additive and a solvent with a single composition.

The heat block assembly includes one or more heat blocks provided with grooves in which reaction containers are inserted, and a temperature adjustor for adjusting the temperature of the heat block.

Abstract: The present invention relates to a preparation method of a general library and a focused library from crude extracts of natural products including herbal drugs, said libraries, and the method for developing new drugs such as an anticancer drug and new substances using said libraries. The method comprises step of attaching crude extract of natural products to the solid phase resin, and step of washing the compounds and reactants that are not attached.

Abstract: The present invention relates to a sustained release formulation comprising protein as an active ingredient, and a preparation method thereof. According to the present invention, the sustained release formulation contains protein drugs that are encapsulated in biodegradable hydrophobic matrices as pharmaceutically active forms by forming complexes with sulfated polysaccharides. The sustained release formulation prepared by the present invention can be used to effectively treat a disease without frequent injections by keeping the protein concentration at a sufficiently high level for a long period when injected in vivo once.

Abstract: The present invention relates to controlled and sustained release pharmaceutical composition and processes for preparing the same. The present invention is to provide processes to prepare an injectable sustained release pharmaceutical composition comprising a step to prepare biodegradable porous microspheres having accessible ionic functional groups, a step to incorporate a biopharmaceutical into the microspheres through ionic interaction by suspending or equilibrating the microspheres in a solution containing the biopharmaceutical and a step to recover and freeze-dry the biopharmaceutical-incorporated microspheres.

Abstract: A process for preparing human insulin, which comprises the steps of: preparing a DNA encoding a human proinsulin derivative having the following formula (I); inserting the DNA into a vector to construct an expression vector for the expression of the human proinsulin derivative; transforming a host cell with the expression vector; culturing the resulting transformant under a condition that allows the expression of the human proinsulin derivative; purifying human proinsulin derivative from the culture; and preparing human insulin from the human proinsulin derivative by an enzymatic hydrolysis:B chain-Z-A chain (I)Wherein,said A and B chains are respectively human insulin chains;Z is a peptide of formula U-U-X-P-J-(X')n-U-U;U is an arginine or lysin residue;X and X' are independently any amino acid residue;P is a proline residue;J is a glycine, arginine or lysine residue; andn is 0 or an integer of 1 to 5.
