A new triterpenic glucoside, lup-1,5,20(29)-trien-3-O-beta-D-glucopyranoside (4), along with three known phytoconstituents: n-octacosane, friedelin and beta-amyrin, has been isolated from the leaves of Clerodendrum inerme (L.) Gaertn. (Verbenaceae). Structure elucidation was carried out on the basis of chemical and physical evidence (IR, 1H-NMR, 13C-NMR, DEPT and MS spectra). The alcoholic and aqueous extracts of the leaves of C. inerme showed significant antinociceptive activity in analgaesiometer tests.

Despite the unprecedented therapeutic potential of immune checkpoint antibody therapies, their efficacy is limited partly by the dysfunction of T cells within the cancer microenvironment. Combination therapies with small molecules have also been explored, but their clinical implementation has been met with significant challenges. To search for antitumor immunity activators, the present study developed a cell-based system that emulates cancer-attenuated T cells.

Excessive exercise can lead to fatigue, consequently affect exercise performance, and further have an adverse impact to human health. The synergistic effects of ginsenosides, salidroside, and syringin on improving exercise performance remain unknown. Hence, the effects of Chinese herb powder (CHP) which consisted of bioactive compounds such as ginsenosides (Rg1, Re, and Rb1), salidroside, and syringin on exercise performance, energy metabolism, tissue damage, antioxidant activity, and inflammatory cytokine were investigated in exhaustive exercise rats.

Article Synopsis
  • Amphiphilic natural sweeteners like steviol glycosides (STE) and glycyrrhizic acid (GA) enhance the properties of starchy products by influencing their chain behaviors such as unwinding and movement.
  • The study used molecular dynamic simulations and experiments to show that both sweeteners promote chain unwinding while preventing long-term reassociation, with GA being more effective than STE in these aspects.
  • At higher concentrations, GA significantly alters the microstructure of starch, resulting in increased hardness and a slower rate of starch digestion, which may be beneficial for developing new starch-sweetener composite materials.
