Chitinase-A (PrChi-A), of molecular mass 42 kDa, was purified from the leaves of a fern (P. ryukyuensis) using several column chromatographies. The N-terminal amino acid sequence of PrChi-A was similar to the lysin motif (LysM). A cDNA encoding PrChi-A was cloned by rapid amplification of cDNA ends

PrChiA is an antifungal chitinase obtained from Pteris ryukyuensis, a fern plant. It consists of two N-terminal lysin motif (LysM) domains and a C-terminal catalytic domain of glycoside hydrolase family 18. Previous studies have shown that the deletion of LysM domains or loss of hydrolytic activity

OBJECTIVE To investigate the effect of Pteris semipinnata L. (PsL) extract Ent-11alpha-hydroxy-15-oxo-kaur-16-en-19-oic-acid (5F)-on HepG2 cells and explore its potential mechanism. METHODS Cytotoxicity of 5F was studied in HepG2 cells treated with different doses of 5F (0 - 80 mg/L) for 24 h and

Ent-11α-hydroxy-15-oxo-kaur-16-en-19-oic acid (11αOH-KA) is a multifunctional biochemical found in some ferns, Pteris semipinnata, and its congeneric species. Although a number of therapeutic applications of 11αOH-KA have been proposed (e.g., anti-cancer,

The objective of the study was to characterize silver nanoparticles (Ag-NPs) and their bioactivities in early tracheophytes (Pteridophyta). Aqueous leaf extract of a critically endangered fern, Pteris tripartita Sw., was used for one-step green synthesis of Ag-NPs. The biosynthesized Ag-NPs were

Leishmaniasis is a vector-borne disease caused by flagellated protozoan parasites of the genus Leishmania, which affects both humans and other mammals. Most of the available drugs against the disease are toxic and parasite resistance to some of the drugs has already developed. In the present study,

Human colorectal cancer (CRC) is a major cause of cancer morbidity and mortality, and its incidence rates are increasing in economical transitioning areas globally. To develop efficient chemotherapy drugs for CRC, the present study isolated and identified a novel ent-kaurane diterpenoid from Pteris

Ent-11-hydroxy-15-oxo-kaur-16-en-19-oic-acid (5F) isolated from Pteris Semipinnata L is known to inhibit certain tumor cells in vitro. The information on the in vivo effect of 5F is limited and its effect on hepatocellular carcinoma (HCC) is unknown. In this study, the anti-tumor effect of 5F was
