Several inflammatory mediators that are implicated in vascular
permeability and shock are produced after
dengue virus infection by
monocytes, the primary targets for virus replication. Here we assessed the
immunoregulatory and antiviral activities from Uncaria tomentosa derived
samples, which were tested in an in vitro dengue virus infection model. Our
results indicate the antiviral and immunomodulating in vitro effects from
Uncaria tomentosa pentacyclic oxindole alkaloids displayed novel properties
regarding therapeutic procedures in Dengue Fever and might be further
investigated as a promising candidate for clinical application.

The woody Amazonian vine Uncaria tomentosa (cat's claw) has been recently more
and more popular all over the world as an immunomodulatory, antiinflammatory and
anti-cancer remedy. This study investigates anti-proliferative potency of
several cat's claw preparations with different quantitative and qualitative
alkaloid contents on HL-60 acute promyelocytic human cells by applying trypan
blue exclusion and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide
reduction assay (MTT). By standardization and statistical comparison of the
obtained results pteropodine and isomitraphylline are indicated to be most
suitable for standardization of medical cat's claw preparations.

Uncaria tomentosa, also known as cat's claw, isa Peruvian Rubiaceae
species widely used in traditional medicine for the treatment of a wide range of
health problems. There is no report about the use, safety, and efficacy of
Uncaria tomentosa in neurological disorders. We describe reversible worsening of
motor signs in a patient with Parkinson disease after oral intake of Uncaria
tomentosa, and some possible explanations are discussed.
