2-Phenyl-5,6,7,8-tetra-hydro-imidazo[2,1-b][1,3]benzo-thia-zole.

The title compound, C15H14N2S, crystallizes with two independent mol-ecules in the asymmetric unit. The central imidazo[2,1-b][1,3]benzo-thia-zole unit is planar (r.m.

2-(Adamantan-1-yl)-N-(6-meth-oxy-1,3-benzo-thia-zol-2-yl)acetamide.

The asymmetric unit of the title compound, C20H24N2O2S, contains two independent mol-ecules having very similar geometries. The main N-(6-meth-oxy-1,3-benzo-thia-zol-2-yl)acetamide moiety adopts an almost planar structure (r.m.

Study of peptide fractions from hemolymph of Galleria mellonella.

Changes in the peptide composition of hemolymph of Galleria mellonella larvae induced by their immunization have been studied, and some new peptides have been found. The composition of fractions exhibiting antibacterial activity was investigated. Known antibacterial peptides have been found in the hemolymph of control larvae and those immunized with bacteria.

[Study of peptide content of antibacterial fractions by liquid chromatography and mass spectrometry].

The fractions containing antimicrobic peptides have been purified from a haemolymph of caterpillars Galleria mellonella by chromatographic methods and studied by mass spectrometry.

[Comparison of the results of research of hemolymph immunized and nonimmunized of larvae of Galleria mellonella].

This work deals with the antibacterial activity of larvae of Galleria mellonella. Protein fractions with antibacterial activity have been purified from hemolymph by ion-exchange chromatography and gel-electrophoresis. The mass-spectrometric analysis of fractions showed the presence of a peptide of 5627 Da.
