Caged xanthones: Potent inhibitors of global predominant MRSA USA300

Total of 22 caged xanthones were subjected to susceptibility testing of global epidemic MRSA USA300. Natural morellic acid showed the strongest potency (MIC of 12.5 μM). However, its potent toxicity diminishes MRSA therapeutic potential. We synthetically modified natural morellic acid to yield 13 derivatives (3a-3m). Synthetically modified 3b retained strong potency in MRSA growth inhibition, yet the toxicity was 20-fold less than natural morellic acid, permitting the possibility of using caged xanthones for MRSA therapeutic.

Mild oxidative cleavage of 9-BBN-protected amino acid derivatives

Protection of the amino acid moiety using 9-BBN is an effective method to enable side chain manipulations in synthesis of complex amino acids. We investigated the standard, mild method for deprotection of the 9-BBN group in methanolic chloroform, and found that it relies on a slow oxidation mediated by molecular oxygen. Building on this insight, we have developed a method that allows for a fast and selective deprotection using simple peroxy acid reagents. After Fmoc protection, products were isolated in >90% yield for a series of amino acid derivatives, including a galactosylated derivative of hydroxylysine. A representative set of 9-BBN-protected amino acid derivatives were efficiently deprotected using peracid reagents in excellent yields. Deprotection is orthogonal with several common protecting groups. Its tolerance of highly acid sensitive groups, such as trityl-protected amides and glycosidic linkages, is especially notable.

NOVEL PEPTIDES DERIVED FROM NCAM (FGLs)

The present invention relates to novel compounds comprising at most 13 contiguous amino acid residues derived from the fibronectin type 3,I1 module of neural cell adhesion molecule (NCAM), or a variant or fragment thereof, capable of interacting with an FGFR and thereby the compounds are capable of inducing differentiation, modulating proliferation, stimulate regeneration, neuronal plasticity and/or survival of cells.

Flanking peptides of calcitonin and processes for their manufacture

Peptides of formula I STR1 in which R is hydrogen or acetyl and X is an amino acid sequence of formula -Ser-Leu-Asp-Ser-Pro-Arg-Ser- (Ia) or of formula -Arg-Ile-Ile-Ala-Gln- (Ib), and salts of such compounds, can be used for the treatment of diseases involving bone degeneration.

Compounds of the formula I, STR1 in which 'R1 is an amino protective group, and n stands for 1 or 2, R1 denotes hydrogen or an amino protective group, R2 denotes hydrogen or a carboxyl protective group and R3 denotes triphenylmethyl, 4-monomethoxy-trityl or 4,4'-dimethoxy-trityl, and reactive carboxylic acid derivatives of such compounds of the formula I in which R2 stands for hydrogen, are described. These compounds can be used as starting materials for the preparation of peptides. They are more suitable for this than are analogous compounds of the formula I in which R3 denotes hydrogen or one of the carbamoyl protective groups hitherto customary.

Protection of carboxamide functions by the trityl residue. Application to peptide synthesis

Carboxamide functions may be tritylated by an acid-catalyzed reaction with triphenylmethanol and acetic anhydride in glacial acetic acid. The ω-trityl group of asparagine and glutamine is cleavable by TFA, but stable to strong mineral acids in aqueous solution, as well as to nucleophiles and bases. In peptide syntheses, it is ideally suited for combination with side-chain protections of the t.butyl-type.
