The in vitro antifungal activities of 19 structurally diversified analogues of pseudolaric acids tested against the major pathogenic fungus Candida albicans has led to the establishment of a very clear structure-activity relationship of pseudolaric acids derivatives. Pseudolaric acid A was first
Pseudolaric acid B [1] was isolated and identified as the main antifungal constituent of Pseudolarix kaempferi using bioassay-directed fractionation. Pseudolaric acid B was active against Trichophyton mentagrophytes, Torulopsis petrophilum, Microsporum gypseum, and Candida spp., while its methylated
Hydrogen is a therapeutic antioxidant that has been used extensively in clinical trials. It also acts as a bioactive molecule that can alleviate abiotic stress in plants. However, the biological effects of hydrogen in somatic embryos and the underlying molecular basis remain largely unknown. In this
Three novel diterpenoids, pseudolaric acids A, B and C, were isolated from the root bark of Pseudolarix kaempferi Gorden used as an antifungal agent in folk medicine in China. The structures of pseudolaric acids B and C were assigned as 1 and 6 by spectral and chemical evidence. Pseudolaric acids A,
OBJECTIVE
To screen antifungal activity of endophytes from Pseudolarix kaempferi.
METHODS
Endophytes from P. kaempferi were separated. By means of microdilution method, antifungal active endophytes were fast screened by Pyricularia oryzae P-2b model, and activity of endophytes against pathogenic
Pseudolaric acid B (PAB), which is the main biologically active diterpene acid of Pseudolarix kaempferi, has presented anti-fungal, anti-tumor, anti-fertility, and anti-tubulin activities. In this study, a sensitive and selective liquid chromatography tandem mass spectrometry (LC-MS/MS) method with
BACKGROUND
From over 100 Chinese clinical trial publications, we retrieved 22 commercial preparations and 17 clinical prescriptions used as Traditional Chinese Medicine (TCM) for treating mycotic vaginitis, typically caused by Candida albicans. The 8 most frequently used plants as well as another 7
Pseudolaric acid-B (PLAB), a diterpene acid, was isolated from the root and trunk barks of Pseudolarix kaempferi. It has shown antifungal and anti-fertility effects and cytotoxic activities in previous studies. Our goals are to study the effects of PLAB on cell proliferation and Smad signal pathway
OBJECTIVE
Pseudolaric acid B (PAB), the naturally occurring diterpenoid isolated from the root bark of Pseudolarix kaempferi Gordon tree (Pinaceae), possesses potent antifungal and pregnancy-terminating effects that may be tightly associated with angiogenesis. This study was to examine its
We report the enantioselective synthesis of pseudolaric acid B (1a), a diterpene acid isolated from the bark of Pseudolarix kaempferi Gordon, which displays interesting antifungal, antifertility, and cytotoxic activity against multidrug resistant cell lines. Our synthesis utilizes a highly efficient
Pseudolaric acid B (PAB) is the most active constituent extracted from the bark of Pseudolarix kaempferi, which has been used as an antifungal remedy in traditional Chinese medicine. It is reported to have cytotoxicity to many tumor cell lines. In this study, we investigated the effects of PAB
Pseudolaric acid B (PAB) is the major bioactive constituent in the root bark of Pseudolarix kaempferi and has been reported to have cytotoxicity against tumor cells. Our in vivo experiments showed that PAB could inhibit gastric cancer cell lung metastasis in a nude mouse haematogenous dissemination
Pseudolaric acid B (PAB) is a novel diterpenoid, isolated from Pseudolarix kaempferi Gorden, which roots are widely used to treat inflammatory and microbial skin diseases for centuries, but the underlying mechanism remains elusive. To address the immunoregulatory mechanisms of PAB, we first
Atherosclerosis is regarded as a chronic inflammatory disease which immune response is regulated by multiple factors. Pseudorlaric acid D (PLAD) is the main bioactive component of Pseudolarix kaempferi Gorden, but little of its property has been found in the literature. We aimed to investigate the
Recently, traditional Chinese medicine has gained attention for its potential use as a chemotherapeutic agent. Pseudolaric acid B (PAB) is a diterpene acid isolated from Pseudolarix kaempferi and possesses antifungal, antimicrobial, antifertility and antiangiogenic properties. It was also reported
