OBJECTIVE Pseudolaric acid B (PAB), a diterpene acid isolated from the root bark of Pseudolarix kaempferi Gordon, has shown to exert anti-tumor effects via inducing cell cycle arrest followed by apoptosis in several cancer cell lines. Here we reported that PAB induced a mitotic catastrophe in human

Type-1 immunity plays a crucial role in host defense against various tumors and infectious diseases. Here, we first demonstrated that extract of Larix Leptolepis (ELL), one of the most popular timbers at Hokkaido area in Japan, strongly activated Type-1 immunity. ELL induced production of Type-1

Pseudolaric Acid B (PAB), diterpenoid isolated from the root bark of Pseudolarix kaempferi Gordon tree (Pinaceae), exhibits an anti-proliferative and apoptotic activity in various cancer cell lines but to date, the effects of PAB on head and neck cancer (HNC) cell lines remain to be

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

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

Pseudolaric acid B (PAB) is a diterpene acid isolated from the root and trunk bark of Pseudolarix kaempferi Gordon (Pinaceae). Recent studies have reported that PAB exhibits cytotoxic effects in several cancer cell lines. In the present study, we assessed its antitumor activity and molecular

Pseudolaric acid B (PAB) is a diterpene acid isolated from the bark of the root and trunk of Pseudolarix kaempferi Gordon (Pinaceae), which has demonstrated cytotoxic effects against various types of cancer. However, the mechanisms underlying the anticancer effects of PAB have remained to be

Pseudolaric acid-B (PLAB), a diterpene acid, was isolated from the root and trunk barks of Pseudolarix kaempferi. It showed antifungal and anti-fertility effects as well as cytotoxic activities in previous studies. The present study investigates cytotoxic activity on cultured human cancer cells,

Pseudolaric acid B (PAB), a diterpene acid isolated from the root bark of Pseudolarix kaempferi Gordon, exerts anti-tumor effects in several cancer cell lines. Our previous study showed that PAB mainly induced senescence via p53-p21 activation rather than apoptosis in suppression of the growth of

A full-length cDNA and genomic sequences of a translationally controlled tumor protein (TCTP) gene were isolated from Japanese larch (Larix leptolepis) and designated LaTCTP. The length of the cDNA was 1, 043 bp and contained a 504 bp open reading frame that encodes a predicted protein of 167 amino

Two novel rearranged abietane-type diterpene acids, karamatsuic acid (1) and larikaempferic acid (2) were isolated as their corresponding methyl esters, 1a and 2a, from the leaves of Larix kaempferi (Lamb.) Carr. Their structures were established as 9,10

Six new lignans (2-7) were isolated from the bark of Larix olgensis var. koreana, and their structures were determined on the basis of their spectroscopic data. Seven known lignans were also obtained and identified as (+)-lariciresinol 9'-p-coumarate (1), (+)-lariciresinol, (-)-secoisolariciresinol,

Asthma is a common chronic inflammatory disease in which lung airways narrow and produce extra mucus. Numerous medications, such as steroids, are used to prevent or control asthmatic symptoms, but side effects are associated with those medications. There are reports of anti-inflammatory,
