Rhizoma Coptidis (the rhizome of Coptis chinensis Franch) has commonly been used for treatment of diabetes mellitus in traditional Chinese medicine due to its blood sugar-lowering properties and therapeutic benefits which highly related to the alkaloids therein. However, a limited number
Benzylisoquinoline alkaloids (BIQ) are among the most structurally diverse and pharmaceutically valuable secondary metabolites. A plant-specific WRKY-type transcription factor, CjWRKY1, was isolated from Coptis japonica and identified as a transcriptional activator of BIQ biosynthesis. However, the
The rhizome of Coptis chinensis is commonly used in traditional Chinese medicine alone or in combination with other herbs to treat diseases characterized by causing oxidative stress including inflammatory diseases, diabetes mellitus and neurodegenerative diseases. In particular, there is emerging
The commercially used cell suspension culture of COPTIS JAPONICA Makino (Ranunculaceae) incorporates [beta- (13)C]tyrosine into both halves of the berberine molecule (isoquinoline and benzyl portion) while L-[3'- (18)O]DOPA only labels the isoquinoline portion of this molecule. This labelling
The effects of protoberberine alkaloids from Coptis japonica Makino (COPT) on catecholamine content and tyrosine hydroxylase (TH) activity in PC12 cells were investigated. The butanol (BuOH) fraction from COPT at a concentration of 40 micrograms/ml medium inhibited catecholamine biosynthesis. The
Opium poppy (Papaver somniferum) produces a large number of benzylisoquinoline alkaloids, including morphine and sanguinarine, derived from tyrosine via the branch-point intermediate (S)-reticuline. Molecular clones for the three methlytransferases involved in (S)-reticuline biosynthesis,
Coptis chinensis Franch., the Chinese goldthread ('Weilian' in Chinese), one of the most important medicinal plants from the family Ranunculaceae, and its rhizome has been widely used in Traditional Chinese Medicine for centuries. Here, we analyzed the chemical components and the transcriptome of
The study carry out comprehensive transcriptome analysis of C. deltoidea and exploration of BIAs biosynthesis and accumulation based on UHPLC-MS/MS and combined sequencing platforms. Coptis deltoidea is an important medicinal plant with a long history of medicinal use, which is rich in
The epidermal growth factor receptor (EGFR)‑tyrosine kinase inhibitor (TKI), gefitinib, is an effective therapeutic drug used in the treatment of non‑small cell lung cancers (NSCLCs) harboring EGFR mutations. However, acquired resistance significantly limits the efficacy of EGFR‑TKIs and
Objective: Berberine (BBR), which is extracted from traditional Chinese herb, is abundant in Coptis chinensis and Berberis vulgaris, with a treatment on type 2 diabetes mellitus (T2DM). However, its oral bioavailability is poor.
OBJECTIVE
To investigate the effect of Jiaotai Pill (, JTP) at different constitutional proportions on insulin signaling through phosphatidylinositol 3-kinase (PI3K) pathway in the skeletal muscle of diabetic rats.
METHODS
The rat model of type 2 diabetes mellitus (T2DM) was established by
