Hygrolidin is a macrocyclic lactone originally isolated from S. hygroscopicus. It inhibits proliferation of a variety of cancer cell lines, including DLD-1 colon cancer, LNCaP prostate cancer, and K562 leukemia cells (IC50s = 2.9, 5.2, and 33 ng ml, respectively). Hygrolidin induces the expression and levels of p21 in DLD-1 cells, but not WI-38 fibroblasts, and leads to cell accumulation in the G1 and S phases without inducing apoptosis. It has antiparasitic activity against T. cruzi, L. donovani, and T. b. brucei but also induces cytotoxicity in HepG2 cells (IC50s = 1.1, 72.5, 77, and 24.5 nM, respectively).

Salviandulin E, a diterpenoid isolated from Salvia leucantha CAV., exhibits antitrypanosomal activity against T. b. brucei GUTat 3.1 parasites, demonstrating an IC50 value of 0.72 µg mL [1] [2].

Orfamide A, a lipopeptide biosurfactant isolated from P. protegens, exhibits multifaceted bioactivity. With an LC50 of 34.5 μg/ml, it significantly increases mortality in adult green peach aphids. Additionally, at a concentration of 50 μM, Orfamide A inhibits appressoria formation in M. oryzae isolates and decreases the prevalence of sporulating blast lesions in M. oryzae-infected plants. Furthermore, it demonstrates efficacy against T. b. brucei, with an IC50 value of 6 µM.
