In a single transient middle cerebral artery occlusion model of stroke and using immunohistochemical techniques, the effects of a new therapeutic approach named Gemst (a member of the Poly-L-Lysine innovative therapies) have been studied in the rat brain. The expression of inflammatory (CD45, CD11b), oxidative (NO-tryptophan, NO2-tyrosine) and indoleamine 2, 3-dioxygenase pathway (kynurenic aci...

BACKGROUND Recently, the discovery of the elansolids, a group of macrolides, was reported. The molecules show activity against methicillin-resistant Staphylococcus aureus as well as other gram-positive organisms. This fact renders those substances a promising starting point for future chemical development. The active atropisomers A1/A2 are formed by macrolactonization of the biosynthesis produc...

Some strains of Bradyrhizobium japonicum have the ability to catabolize indole-3-acetic acid (IAA). Examination of this catabolism in strain 110 by in vivo experiments has revealed an enzymatic activity catalyzing the degradation of IAA and 5-hydroxy-indole-3-acetic acid. The activity requires addition of the substrates for induction and is oxygen dependent. The highest activity is obtained whe...

Thomas Nelson Baker Jr. may not be a household name, but he clearly represents the many African Americans that have achieved great success in higher education during a volatile racial period in our history (1). A native of Pittsfield, Massachusetts, Baker began his undergraduate studies at Oberlin College (Oberlin, Ohio) and earned his B.A. and M.A. in chemistry in 1929 and 1930, respectively. ...

The synthetic access to 2-sec-amino-4H-3,1-benzothiazin-4-ones 2 was explored. Compounds 2 were available from methyl 2-thioureidobenzoates 1, 2thioureidobenzoic acids 3, and novel 2-thioureidobenzamides 6, respectively, under different conditions. 2-Alkylthio-4H-3,1-benzothiazin-4-ones 5 have been prepared from anthranilic acid following a two step route. Both, benzothiazinones 2 and 5 underwe...

Eleven carbazole (CAR)-degrading bacterial strains were isolated from seawater collected off the coast of Japan using two different media. Seven isolates were shown to be most closely related to the genera Erythrobacter, Hyphomonas, Sphingosinicella, Caulobacter, and Lysobacter. Meanwhile, strains OC3, OC6S, OC9, and OC11S showed low similarity to known bacteria, the closest relative being Kord...
