BACKGROUND: The World Health Organization (WHO) reported that colorectal cancer (CRC) was the third most common cancer in men and the second in women, worldwide. Our previous meta-analysis found Sophora flavescens increased tumour response rate in randomised controlled trials of CRC. We hypothesised that its principal constituent matrine had exerted anti-tumour effects. PURPOSE: To elucidate its mechanisms of action we investigated the dose-related anti-tumour effects of matrine on four human CRC cell-lines: LS174T, Caco-2, SW1116 and RKO...

BACKGROUND: Endoplasmic reticulum (ER) stress, which can promote lipid metabolism disorders and steatohepatitis, contributes significantly to the pathogenesis of nonalcoholic fatty liver disease (NAFLD). Calcium (Ca2+ ) homeostasis is considered to play a key role in ER stress. Matrine (Mat) has been applied for the treatment of hepatitis B, but its effect on NAFLD is still unknown, and there is no unified view of Mat on the regulation of ER stress in the previous literature. METHODS: The pharmacological effects were studied in high-fat-diet or methionine-choline-deficient diet induced C57BL/6J mice models and in palmitic acid (PA) induced L02 human liver cell model...

To discover new natural-product-based potential pesticides, 85 matrinic acid/alcohol/ester derivatives were synthesized by structural modifications of a quinolizidine alkaloid matrine. N-(4-Methyl)benzylmatrinyl n-decylate (76) and N-(2-chloro)benzylmatrinyl n-undecylate (86) exhibited greater than 7-fold more pronounced acaricidal activity than matrine against Tetranychus cinnabarinus; N-(2-chloro)benzylmatrinyl benzoate (80) showed the most promising insecticidal activity against Mythimna separata. The carboxyl group of matrinic acids, and introduction of n-decyl/n-undecylcarbonyl into matrinic alcohols were important for the acaricidal activity; introduction of alkyloxy into the carboxyl of matrinic acids, and introduction of the electron-withdrawing groups on the N-benzyl of matrinic esters were necessary for the insecticidal activity...

Cancer is the second leading cause of mortality, only overcome by cardiovascular diseases, and has caused more than 8.7 million deaths in 2015 all over the world. This figure is expected to rise to about 13.1 million by 2030. In order to prevent or cure this fatal illness, substantial efforts have been devoted to develop and discover new anticancer drugs with same or better antitumor activity but lesser toxicity. Matrine is an alkaloid isolated from Sophora flavescens Ait. For decades, matrine and its derivatives have been studied as antineoplastic agents which predominantly work by inhibiting proliferation and inducing apoptosis of cancer cells...
