The Friedländer reactions of acetylbenzenes and 2-acetylpyridine with 3-aminonaphthalene-2-carbaldehyde afforded the corresponding 2-phenylbenzo[g]quinoline and 2-(pyrid-2-yl)benzo[g]quinoline, respectively. The same reactions of 3-aminonaphthalene-2-carbaldehyde with 1,2-, 1,3-, 1,4-di- and 1,3,5-triacetylbenzenes, however, afforded a series of corresponding (benzo[g]quinolin-2-yl)benzenes as ...

The one-humped camel (Camelus dromedarius) is a seasonal breeder with a relatively short breeding period, when increased ovarian activity is exhibited (Shalash, 1965,1980; Nawito, Shalash, Hoppe ¿St Rakha, 1967 ; Novoa, 1970). In Israel, the normal breeding season occurs from December to early April. Female camels come into heat during this period and exhibit mainly follicular activity; there i...

MICE WERE INJECTED INTRAPERITONEALLY WITH ONE OF THE FOLLOWING BACTERIAL PRODUCTS HAVING ENDOTOXIN ACTIVITY: pertussis vaccine, a suspension of heat-killed cells of Klebsiella pneumoniae (type C), or a purified lipopolysaccharide prepared from cultures of Salmonella typhosa. Following treatment with either one of these materials, the animals were infected intravenously with virulent cultures of...

A synthetic approach to the heterodimeric bisindole alkaloid leucophyllidine is disclosed herein. An enantioenriched lactam building block, synthesized through palladium-catalyzed asymmetric allylic alkylation, served as precursor both hemispheres. The eburnamonine-derived fragment was a Bischler–Napieralski/hydrogenation approach, while eucophylline-derived by Friedländer quinoline synthesis a...

1. The meningococcus polysaccharide reacts with a broad precipitable carbohydrate antibody in common with those of B. anthracis, B. subtilis, B. proteus and B. mesentericus. 2. The anthrax and proteus polysaccharides are specific in the higher dilutions of serum. 3. Antianthrax serum contains two different polysaccharide precipitable antibodies, one specific and the other non-specific. 4. Agglu...
