Abstract: The present invention relates to a peptide with anti-inflammatory activity, wherein the peptide comprises any one amino acid sequence of SEQ ID NO: 1 to SEQ ID NO: 161, the peptide has above 80% homology of amino acid sequence with above-mentioned sequences, or the peptide is the fragment of the above-mentioned peptides. The present invention also relates to an inflammatory composition comprising the above mentioned peptides. According to the present invention, a peptide that has at least one amino acid sequence of SEQ ID NO: 1 to SEQ ID NO: 161 has outstanding efficacy in both suppressing inflammation and in prophylactic means. Therefore, the composition comprising the peptides of this invention can be used as anti-inflammatory pharmaceutical compositions or as cosmetic compositions, in turn, treating and preventing a variety of different types of inflammatory diseases.

Abstract: This invention relates to compounds of Formula I having an aziridine-2-carboxylic group and a menthol group, a process for preparing such compounds, a method for obtaining optically active aziridine-2-carboxylate derivatives by optical resolution of such compounds, and optically active aziridine-2-carboxylate derivatives obtained by the same method: 1

Abstract: A process for the production of N-substituted aminoethylphosphonic acid derivatives represented by the formula (I) is disclosed ##STR1## wherein R.sub.1 is an alkyl having 1-18 carbon atoms or a cycloolkyl having 3-18 carbon atoms and R.sub.2 is hydrogen, methyl or ethyl. This process comprises the steps of: reacting N-alkyl and N-cycloalkylhexahydro-s-triazine of formula ##STR2## with trialkylphosphites of formulaP(OR.sub.2).sub.3in the presence of titanium tetrahydrochloride at -20.degree.-10.degree. C. to yield N-substituted aminomethylphosphonic acid dialkylesters, followed by hydrolysis to yield N-substituted aminomethylphosphonic acid.

Abstract: There is disclosed a novel process for the preparation of N-phosphonomethylglycine of formula(I) ##STR1## (wherein, R and R.sup.1 are selected from the group consisting of alkyl having 1 to 2 carbon atoms) which process comprises reacting 1,3,5-tricarboalkoxymethylhexahydro-s-triazine with trialkylphosphite in the presence of titanium tetrachloride to form N-phosphonomethylglycine triester and converting the triester into a N-phosphonomethylglycine by saponification.
