Cat’s Claw Oxindole Alkaloid Isomerization Induced by Common Extraction Methods

Cat’s claw oxindole alkaloids are prone to isomerization in aqueous solution. However, studies on their behavior in extraction processes are scarce. This paper addressed the issue by considering five commonly used extraction processes. Unlike dynamic maceration (DM) and ultrasound-assisted extraction, substantial isomerization was induced by static maceration, turbo-extraction and reflux extrac...

Cat claw injuries in corneas of dogs and cats

Cats have retractable claws which are versatile tools used for climbing, defence, balance, scratching and catching prey. They are also a formidable weapon which can inflict nasty scratches to animals perceived by the cat to be a threat (or a nuisance!). The most frequent victim is a younger dog, which is typically curious and has not yet learned to read hostile signals. They also do not develop...

Binding of an oxindole alkaloid from Uncaria tomentosa to amyloid protein (Abeta1-40).

The primary aim of this work was to determine the interactions of an oxindole alkaloid (mitraphylline) isolated from Uncaria tomentosa with beta-amyloid 1-40 (Abeta1-40 protein) applying the capillary electrophoresis (CE) method. Specifically the Hummel-Dreyer method and Scatchard analysis were performed to study the binding of oxindole alkaloids with Abeta1-40 protein. Prior to these studies e...

Sleep induced by intestinal stimulation in cats.

The influence of afferent impulses of intestinal origin on the sleep stages was studied in fed and starved cats. Low-frequency electrical stimulation of the mucosal surface in a small intestinal fistula reduced the latency of sleep onset. The number of slow wave sleep episodes decreased, but their mean duration increased during stimulation. Conversely, the number of paradoxical sleep episodes i...

Photocyclic behavior of rhodopsin induced by an atypical isomerization mechanism.

Vertebrate rhodopsin (Rh) contains 11-cis-retinal as a chromophore to convert light energy into visual signals. On absorption of light, 11-cis-retinal is isomerized to all-trans-retinal, constituting a one-way reaction that activates transducin (Gt) followed by chromophore release. Here we report that bovine Rh, regenerated instead with a six-carbon-ring retinal chromophore featuring a C11=C12 ...
