I (R = oxazolyl, isoxazolyl, thiazolyl, isothiazolyl) were prepd. Thus monic acid A was amidated with PhCOCH2NH2.HCl and the amide cyclized to give I (R = 5-phenyl-2-oxazolyl) which had a min. inhibitory concn. against various Mycoplasma suipneumoniae strains of 0.5-1.0 mg/mL. .

DOCUMENT TYPE: Journal CA Section: 34 (Amino Acids, Peptides, and Proteins) A symposium report. A photoremovable auxiliary for peptide synthesis via the chem. ligation method is described. An auxiliary group, 2-mercapto-1-(2-nitrophenyl)ethylamine (Mnpe-amine), was prepd. 6851-99-6 which is the cas registry number of some chemical is mentioned. from 2-bromo-2'-nitrobenzophenone and attached to the N-terminus of a peptide. The resulting peptide was then ligated to a peptide thioester and UV (365 nm)-irradn. resulted in the removal of the auxiliary from the peptide. .
