AI Article Synopsis
- 12 new selenium compounds inspired by the herbicide Cafenstrole were developed and analyzed using various scientific methods.
- Certain compounds, like C2, C4, C(7-8), and C12, demonstrated effective weed control, particularly C6, which significantly inhibited cucumber and Leptochloa chinensis growth.
- C6 showed over 90% inhibition at a low concentration, while it had minimal impact on rice, indicating it could be a more selective herbicide compared to Cafenstrole.
Article Abstract
Based on the carbamoyl triazole herbicide Cafenstrole, 12 novel selenium-containing compounds were designed and synthesized. All of the compounds were characterized and confirmed by IR, 1H NMR, and high-resolution mass spectroscopy. The bioassay tests showed that some of the compounds (C2, C4, C(7-8), and C12) exhibited good inhibitory activity against cucumber (Cucumis sativus L.) and semen euphorbiae (Leptochloa chinensis N.). Especially, compound C6 inhibited the growth of cucumber and semen euphorbiae by >90% at a concentration of 1.875 microg/mL, and the inhibition of the compound on the rice (Oryza sativa L.) was only 8.3% at a concentration of 7.5 microg/mL, which indicated a higher selectivity between weed and rice than that shown by Cafenstrole.

Background: Casticin (CAS), a natural flavonoid found in Viticis Fructus, Viticis Cannabifoliae Fructus, and Semen Euphorbiae, shows anti-inflammatory activity and efficacy against various cancers. However, its effect on stemness associated with self-renewal in cervical cancer (CC) cells remains unclear, as well as the underlying mechanism.
Purpose: The primary objective of this study was to examine the effect of CAS on CC stemness and to explore the underpinning regulatory mechanism.

Lathyrol is a natural product isolated from the traditional Chinese medicine Semen Euphorbiae with unknown anti-tumor effects. We found that lathyrol had significant inhibitory effect on lung cancer cells by inducing apoptosis and inhibiting proliferation. Subsequently, we demonstrated for the first time that endoplasmic reticulum (ER) stress is a key anti-tumor mechanism of lathyrol.

Semen Euphorbiae (SE) is a toxic traditional Chinese medicine made from the dry or mature seed of Euphorbia lathyris L. Research demonstrates that the toxic side-effects from eating SE are associated with intestinal disturbance. By processing to produce Semen Euphorbiae Pulveratum (SEP), the toxicity is reduced, and diarrhea is attenuated.

Euphorbiasteroid, a lathyrane-type diterpene from (the seeds of L.), has been shown to have a variety of pharmacological effects such as anti-tumor and anti-obesity. This study aims to investigate the metabolic profiles of euphorbiasteroid in rats and rat liver microsomes (RLMs) and bio-110930 by integrating ultra-performance liquid chromatography-quadrupole time-of-flight-mass spectrometry (UPLC-Q/TOF-MS), UNIFI software, and NMR techniques.
