Description and Uses

()-Catechin gallate has been used:

• to examine the potency of catechins containing galloyl moiety in inhibiting the activity of human immunodeficiency virus-1 (HIV-1)integrase
• to analyze the anti-oxidant and anti-viral properties of Pseudopiptadenia contorta and the commercial quebracho extracts in a herpes simplex virus type 1 strain, resistant to acyclovir
• to study the effects of polyphenols on the biochemistry of human spermatozoa and the associated limitations of their use in gamete preservation
