摘要:Disclosed is a method of the synthesis of ramalin. It comprises reacting a glutamic acid derivative, which is prepared using alkylchloroformate, with a hydrazine salt compound, which is prepared from hydroxy aniline, whether protected or not. The synthesis method allows ramalin, excellent in antioxidant and anti-inflammatory activity, to be simply synthesized at stable yield even without use of a highly toxic solvent such as DMF. In addition, the method is cost competitive, and provides ramalin at high efficiency, thus enabling the mass production of ramalin.

摘要:In the present invention are disclosed concatemers of concatenated expression cassettes and vectors that enable the synthesis of such concatemers. The concatemer comprises in the 5′→3′ direction a cassette of nucleotide sequence of the general formula [rs2-SP-PR-X-TR-SP-rs1]n wherein rs1 and rs2 together denote a functional restriction site, SP individually denotes a spacer of at least two nucleotide bases, PR denotes a promoter, capable of functioning in a cell, X denotes an expressible nucleotide sequence, TR denotes a terminator, and SP individually denotes a spacer of at least two nucleotide bases, and n>/=2, and wherein at least a first cassette is different from a second cassette. The main purpose of these concatemers is the controllable and co-ordinated expression of large numbers of heterologous genes in a single host. Furthermore, the invention relates to a concatemer of cassettes of nucleotide sequences and a method for preparing the concatemers. In a further aspect, the invention relates to transgenic host cells comprising at least one concatemer according to the invention, as well as to a method for preparing the transgenic host cells. Finally, the invention relates to a vector comprising a cassette of nucleotides, a method for preparing said vector, a nucleotide library comprising at least two primary vectors each comprising a cassette of nucleotides, a method for preparing the library.

摘要:The synthesis of a series of Polyethylene glycol conjugates (esters and carbonates) of PEA and its analogous acylethanolamides, have higher water solubility and good hydrophilic/lipophilic balance, resulting in (i) improved accumulation in tissues (particularly skin and mucosae), (ii) prolonged release, and (iii) increased bioavailability. Improvement of PEA and analogous acylethanolamides levels in the tissues—particularly in the skin and mucosae—and their prolonged release is due to the improved bioavailability of related conjugates. Conjugates are able to extend the time frame in which PEA and analogous acylethanolamides exert their pharmacological effects.

标 题 :Screen for inhibitors of melanin biosynthesis
发明人：BRINDLE FRANCES HARRIET ELIZAB; FROELIGER EUNICE HARRIET

摘要:A method for the identification of agents that inhibit melanin biosynthesis involves the incubation of test samples in cultures of a fungus that produces melanin. Observation of altered pigmentation in the culture or culture area containing test sample indicates inhibition of melanin biosynthesis. Preferred cultures for the screen contain a fungus that pigments in the light or the dark such as Cladosporium cucumerinum. Preferred embodiments employ test samples on disks or in wells in solidified cultures and a known melanin synthesis inhibitor as a positive control which is compared to the test sample by simple visual inspection.
