The chemical investigation of a leaf extract from a herbarium specimen of collected in Banyang Mbo Wildlife Sanctuary, Southwest Region, Cameroon, yielded five undescribed abietane diterpenoids, banyangmbolides A-E, (-), and four known diterpenoids, gelomulides A (), B (), D () and O (). The structures of the isolated compounds were determined using NMR, IR, ECD and HRESIMS. Compounds , and , showed 48-55% inhibition at 200 μM against FM-55-M1 human melanoma cells.

Two undescribed oxazole-containing diterpenoids (1-2) and a new diterpenoid (3) were isolated from the roots of Salvia miltiorrhiza. Their structures were elucidated by extensive HRESIMS and NMR spectroscopic analysis, and the absolute configurations of 1 and 3 were confirmed by comparison of the calculated and experimental electronic circular dichroism (ECD) spectra. Compound 1 represents the first example of an abietane diterpenoid with a benzo[d]oxazole unit fused in the ring B of the abietane skeleton.

Transcription factors play a crucial role in the biosynthesis of tanshinones, which are significant secondary metabolites derived from Salvia miltiorrhiza, commonly known as Danshen. These compounds have extensive pharmacological properties, including anti-inflammatory and cardioprotective effects. This review delves into the roles of various transcription factor families, such as APETALA2/ethylene response factor, basic helix-loop-helix, myeloblastosis, basic leucine zipper, and WRKY domain-binding protein, in regulating the biosynthetic pathways of tanshinones.

This study aims to investigate the mechanism of tanshinone Ⅱ_A(Tan Ⅱ_A) in protecting mice from diethylinitrosamine(DEN)/carbon tetrachloride(CCl_4)/ethanol(C_2H_5OH)-induced hepatocellular carcinoma(HCC) and HepG2 cells from hydrogen peroxide(H_2O_2)-induced oxidative damage via the phosphoinositide 3-kinase(PI3K)/protein kinase B(Akt) and nuclear factor E2-related factor 2(Nrf2)/heme oxygenase 1(HO-1) signaling pathways. Sixty male C57BL/6J mice were grouped as follows: control, model, low, medium, and high-dose(10, 20, 40 mg·kg~(-1), respectively) Tan Ⅱ_A, and colchicine(0.2 mg·kg~(-1)), with 10 mice in each group.

Tyrosyl DNA phosphodiesterases 1 and 2 (TDP1 and TDP2), which are enzymes involved in the repair of DNA, are regarded as promising targets for the development of new anticancer drugs. In this study, a series of imidazolidine-2,4-diones, 2,4,5-triones, and 2-thioxoimidazolidine-4,5-diones based on dehydroabietylamine (DHAAm) were synthesized. The inhibitory activity of the new compounds against TDP1 and TDP2, as well as their cytotoxic characteristics, were evaluated.

A series of novel carnosic acid derivatives incorporating urea moieties at the C-20 position was synthesized and evaluated for their antiproliferative activity against the HCT116 colorectal cancer cell line. Most derivatives demonstrated enhanced antiproliferative activity compared to that of carnosic acid . The most promising derivatives were tested in other colorectal cancer cell lines (SW480, SW620, and Caco-2), melanoma (A375), and pancreatic cancer (MiaPaca-2).
