Ardisiphenols and Other Antioxidant Principles from the Fruits of Ardisia colorata
TL;DR: Ardisiphenols showed moderate scavenging activities toward 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals and showed cytotoxicity against the murine breast cancer cell line, FM3A.
Journal ArticleDOI
Immunomodulatory constituents from an Ascomycete, Chaetomium seminudum.
TL;DR: A screening study focusing on immunomodulatory activity of the EtOAc extract of an Ascomycete, Chaetomium seminudum, has afforded a known epipolythiodioxopiperazine, chetomin, together with three new cheTomin-related metabolites named chetoseminudins A, B and C.
Journal ArticleDOI
A new ent-clerodane diterpene from the aerial parts of Baccharis gaudichaudiana.
TL;DR: A new ent-clerodane diterpene was isolated from the aerial parts of Baccharis gaudichaudiana DC and showed moderate scavenging activities toward 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radicals.

Immunomodulatory Constituents from Three Ascomycetes, Gelasinospora heterospora, G. multiforis, and G. longispora
TL;DR: Three new 2-pyrones (2H-pyran-2-ones) called multiforisins G (3), H (1), and I (4), and a known hexaketide sordarial have been isolated from an Ascomycete Gelasinospora heterospora and have been proved to be the immunosuppressive components of the fungus.
